John Zappia silenced all skeptics at the Perth Motorplex yesterday, when the Striker Top Doorslammer Monaro fronted for a local meeting with their new Striker engine combination, and promptly ran a five second pass after a test run, and first full pass of 6.057. The TFX block, with the latest Randy Anderson heads (never raced in Australia), and a brand new PSI blower is John Zappia’s first ever brand new engine – after over 20 years of drag racing.

“Thanks to Striker Crushing and Screening, we were able to custom order all brand new parts to put this combination together. It’s a dream come true for us local sportsman racers, who have always had to purchase hand-me-down second hand engines and blowers from the US.” said a jubilant Zap last night. “People think we made a strategic decision to run with the Whipple blower, but it was nothing more than a budget decision for us at the time, and to have achieved all our world records with second hand gear highlights the depth of knowledge we have in our team. The PSI gives us weight advantages, and it appears to make more power and torque than the Whipple”.

Observers were commenting that Zap will take months and dozens of laps to sort out the awesome performance of the PSI equipped BAE – after all, most of his Australian Top Doorslammer competitors have had years to sort out their PSI combinations and still struggle with their tune ups. But after a shake down pass to gain some data, the team set Zap’s Rat up for it’s first full pass and rattled off a dead straight 6.057et @ 234.37mph. “It was fat and lazy, but showed us the real potential of the combo” said Zap.

With the first full pass under their belt, the team turned the car around for the next qualifier, and had the local crowd on their feet cheering with a 5.991et @ 235.60mph pass. “We ran a 3.929et 660ft time, which is pretty impressive. We will work on the data and some more tuning to get the mph back up again, and we are confident we can reclaim the World’s Quickest Doorslammer record back off the Yanks.”

“We hurt a couple of pistons during the 5.991 pass and had the usual thrash to get the car ready for another pass late in the night.” Unfortunately, after Zap’s burn out the crew noticed oil on the track and quickly shut Zap down. “After an investigation back in the pits we noticed a loose oil line had caused the oil leak. We are now looking forward to the next local meeting where we can fine tune the combination even further.”

Zappia Racing earnt valuable dollars from Striker Crushing Managing Directors Chris Lane and Craig Pedley, who handed over $5,000 as part of a performance bonus. “Every time the team runs a five, we hand over a cheque for $5,000 as an incentive.” said Chris Lane, “We are very proud of Zap and his team with their achievements so far, and we may extend and ramp up our Motorsport program with the team in the future..” Craig was relieved that the team didn’t make the last pass as it would have cost Striker Crushing another $5000, especially as the air was at it’s best of the weekend.

Zappia Racing will carry out further testing and racing on April 14th at the Perth Motorplex, before heading to Queensland for Round 6 of the Australian Top Doorslammer Championship “Tin Tops” event on 28th April. John Zappia is second in the championship point’s table, behind veteran Garry Phillips, and is counting on a strong performance at the event.


Striker Monaro into Semi Final at Westernationals

John Zappia gained valuable points for the ANDRA Top Doorslammer Championship at the Westernationals held last weekend at Perth Motorplex in Western Australia, with a Semi-final finish. The Striker Monaro was unable to continue the Semi-final pass against arch rival Garry Phillips, after the clutch failed reversing from his traditional long smoky burnout.

“I was unable to activate the clutch after reversing back, so I turned the engine off” said a disappointed Zap after the event, “It appears a pin has let go in the clutch – most probably the result of tyre shake of our previous rounds. The Striker Monaro was performing well this weekend, with two 6.06′s in qualifying, and our first round win against Robin Judd with a 6.075et @ 236.22mph. The next best time in all the elimination runs was a 6.340et, so we were still ahead of the pack in performance.”

“We have these little reliability issues, because we do more laps than any other Top Doorslammer racer in the country. Obviously the more laps you do, the more possibilities of incidents occurring. But we are committed to a comprehensive racing calendar both here locally in Perth, and nationally in the championship rounds. We just have to keep progressing forward in our maintenance program to increase the reliability factor.”

“Our Naming Rights Sponsor Striker Crushing and Screening, and all our Major Sponsors and Supporting Sponsors are fully behind our growth as a team. We are progressing from a volunteer backyard operation, to a more professional Motorsport organisation. It takes time to affect the changes and our current way of doing things will have to be altered to ensure we give ourselves the best possible chance every meeting. We need more checks to be done between races to make sure the little things don’t fail and come back to haunt us.”

“Garry Phillips has a lead in the Championship, but he is not unbeatable. He has had his fair share of luck this season, and and on most days the HQ can beat any Doorslammer in the country. Drag racing is the great equaliser, and as several teams have seen this weekend, the smallest of things can stop your best performance.”

Several racers encountered problems this weekend – Ben Bray failed to qualify in his new Monaro, Steve Stanic was disqualified in Round 1 Eliminations due to his front air dam being too low for the stage beams, and several teams suffered terminal engine damage.

Zappia racing will now contest two local rounds of racing at the Perth Motorplex where further testing of new components will be carried out. Round 6 is scheduled for 28th April at Willowbank Raceway with the running of the Tin Top Championships – a unique event featuring all forms of slammer racing.

Westernationals Zappia’s last challenge

Written by Luke Nieuwhof
Monday, 26 February 2007
John Zappia is one of the most renowned names in drag racing, yet he still has a monkey to shake off his back in Top Doorslammer racing at the Westernationals, to be held this Saturday and Sunday at Perth Motorplex.

The 45 year old Spearwood man is driving the world’s quickest Top Doorslammer, holding the record at 5.92seconds for the quarter-mile but his speeds of 380kmh do not come easy.

“We’ve never had good luck and have always had the stupid things go wrong at the Westernationals, he said.

“It is time to shake the monkey off the back; we really need the points to gain the lead in the championship and put the pressure back on the other racers for the remaining rounds.”

The Australian Top Doorslammer Championship is up to its fifth round and Zappia is sitting third, behind Queensland racers Gary Phillips and Victor Bray.

Perth Motorplex has attracted a record field of 15 cars from across the nation to compete and Zappia sees himself with a big advantage at the Kwinana track.

“We do nine events a year in Perth and always in different race conditions,” he said.

“No other team has near that amount of runs.”

In an aggressive tactic, Zappia has slotted his world-record, 3500 horsepower supercharged V8 back into his Monaro Top Doorslammer.

“The field is pretty good but I need to concentrate on not beating myself,” he said.

“A few others have stepped up and if they get the good track conditions then they’ll be right there.”

Zappia will be challenged by his championship rivals Phillips and Bray, as well as Victoria’s Peter Kapiris, New South Wales’ Steve Stanic, Queensland’s husband and wife team of Brett and Kath Stevens, Victor and Ben Bray and fellow West Australian contenders Robin Judd, Gary Stevens and Adam Croker.

The event will also feature round five of the Australian Top Bike Championship.

The big guns hit the track from 6pm on both Saturday and Sunday.

Zap’s Rat III

THE REVIVAL by Kim Soia – Perth Street Car Magazine Vol 4 No1 1996 (used with permission and copyright applies)


The events that followed were a testament to how well liked and popular John Zappia is. Although the Statesman body was ruined, the chassis was only bent in the front half and all the remaining mechanical components survived the crash. When Rick Matson from Legend Boat Builders assisted with funds to fix the chassis, others began to offer their help in a complete rebuild. Pacific Performance in Queensland helped John obtain a 1995 Pontiac Firebird Funny Car body from Jeff Burnett. This was the only option at the time as another Statesman body would take at least 12 months to hand make; which would have been unfair to the sponsors. The Pontiac is currently the fastest and sleekest body shape in modern drag racing which made it even harder to pass up. Murray Anderson Race Cars then replaced the front half of the chassis and bolted up the new body. The new roller was sent by train back to Perth and two weeks later Zap’s crew had finished Zap’s Rat III.


Only six weeks after the demise of Zap’s Rat II, Zap’s Rat III appeared at Ravenswood for its licensing runs. The car put down an easy 6.60 at 218.5mph and went home in one piece! At the 1996 Nationals, Zappia qualified 7th with a 6.16 at 227mph in his new class – Top Alcohol. This class is for supercharged Funny Cars and dragsters (rails) which run on methanol fuel only – no nitro is permitted. Top Alcohol is a very tough class of racing and unfortunately, John was defeated by Stan Tindall’s rail, 5.98 to 6.19. Tindall was later beaten in the final by Gary Phillips who put down a blasting 5.87.

Top Alcohol is a whole new learning curve, so John and his crew were happy with their first Nationals meeting in the new class. Zap realises that 5.80 second passes around 240mph are what is required to win in Top Alcohol and he is confident of achieving these levels given more time and testing. After being so dominant in Top Doorslammer for so many years, John has the desire and skill to succedd at this top level.

Many people think that Zappia’s racing is fully funded by his sponsors but he assures us that this is not true. He operates his team on a very tight budget and makes many of the cars components himself. John has a volunteer crew who give their all at drag racing venues around the country. The cost of racing has risen considerably since his move to Top Alcohol due to the prominence of the screw-type superchargers. These PSI and Whipple blowers have permitted incredible performance gains in recent times but come at a great cost – between $15,000 & $20,000 each.

So there you have it, a complete history of one of W.A.’s most famous and fearless drag racers. From humble beginnings in a 194 Torana, to the domination of A/gas, through the halcyon days of Top Doorslammer to the present challenge in Top Alcohol, John Zappia has achieved a cult status and plans to continue breaking the records that few even pursue. John plans to be the first alcohol driver to run a 5 second pass at Ravenswood and to aquire one of the two remaining positions in Goodyear 5 Second Club.

We have no doubt that with his remarkable record and huge crowd pleasing burnouts that Zappia will achieve these goals. Best of luck to John, his crew and sponsors.

Zap’s Rat II

NEW SURPRISES – SERIES II by Kim Soia – Perth Street Car Magazine Vol 4 No1 1996 (used with permission and copyright applies)


As mentioned previously, John began planning the Statesman by September of that year. Series II was going to be an all new car, but a continuation of the famous Zap’s Rat theme. Series II was always going to be a doorslammer, but it had to have a state of the art centre-steer chassis capable of putting down the huge horsepower produced by the TFX engine. It took six months of hard work to hand fabricate the slippery VR Caprice body as extensive modification of the original steel Statesman panels was required. This was a steel bodied, operating doors funny car. The build was made much easier thanks to the assistance of many friends and sponsors. Cockburn Exhausts built the pipes, Diverse Metals tinned out the new body and gave it opening doors, Southside Engine Centre prepared the engine and mechanicals, Amcap BBK supplied the Holden panels, ICI Autocolour supplied the paint for Base Autos to apply and Syndicate Signs covered the graphics and logos.


The final chapter of the Series II Funny Car is a very sad one which many fans will remember as a tragedy for the car but a lucky escape for John Zappia. The 554 cubic inch, blown TFX alchohol engine Funny Car was not finished until 2.00pm on the afternoon of its first race meeting versus American Jim Shalpi’s 1957 Chev. Zappia’s car was still to be licensed before it could legally race that evening.

In its first ever pass the Series II ran an easy 6.88 at 209mph. Tragically the chutes failed to open and at 7.00pm Zap’s Rat II hit the “safety zone” at the end of the track at over 200mph. The brakes were unable to slow the car before it hit the grass and shot sideways. Series II rolled 3 1/2 times, destroying the beautiful irreplaceable body and bending the state of the art chassis. Thankfully, John Zappia was unhurt, but the car was a mess.


After the crash, the option of a soft sand safety barrier at the end of the track was discussed but John explained that the Monaro had ventured onto the grass several times in the past and that he was able to steer it out of trouble. So the hard grass had helped him. He also explained that soft sand can cause Funny Cars to end over end at high speed. Even in lower speed incidents it is possible for a $70,000 engine to fill up with sand, so a hard surface is preferred.


Zap’s Rat I

The Zappia Chronicles by Kim Soia – Perth Street Car Magazine Vol 4 No1 1996 (used with permission and copyright applies)


John Zappia has a long history of crushing his opposition with achievements such as 1990 Drag Racer of the Year, 1995 Top Doorslammer Champion, the World’s first Super Stock car in the sevens, the first doorslammer in the sixes and the second racer in the 200mph club. John Zappia has defended West Australian honour against the Eastern States and America on many occasions. In the 1989-90 season Zappia won every time he staged the car. Serious domination! Zap’s Rat was the 1990 National’s winner and top qualifier in 1990, 1992, 1993 and 1995.


Zap’s Rat was equally impressive against big reputation USA teams. In the 1992 Australia vs USA Ravenswood Doorslammer Series, he overpowered Wayne Torkelson’s 1959 Thunderbird. In 1994 Zappia crushed Kurt Kuhns 3-0; blasting a 6.57 ET to Kuhns’s 6.62. He has run a personal best of 6.54 at 218mph.

John Zappia began racing in a 14 second 194 CI Torana seventeen years ago. He progressed into a steel bodied HQ 4-door running a 383 small block, turbo 400 and a nine inch diff, which ran a best time of 12.86 at 113mph in 1981.

In 1982 John fitted a big block 454 LS-7 into the 4-door HQ. This only resulted in a marginal improvement to 12.75 at 121mph due to the car’s insistence on doing 1/4 mile burnouts. Due to this disapointing performance and the fact that the 4-door was now too radical for the street, John was forced to think again.


The original Zap’s Rat, 2-door Monaro body was purchased for $350. John kept the LS-7 and initially decided to race in A/Modified production. However, on a trip to the last Castlereagh ADR Grand Finals, Zappia decided a pro-chassis car would better suit his aspirations and so the story really began. In late 1984, the white, all steel, HQ put down it’s first pass – 9.39 at 148mph. This early LS-7 powered Zap’s Rat went on to a best of 9.11 at 151mph with the engine out to 460 cubes.

In the 1986/87 season, Zappia was determined to smash the 8.67/154 AA/Gas record. To destroy this record a blown 427 big block was employed. The first pass on this engine yeilded an 8.69 at 164mph. On the second meeting with the 427, Zap’s Rat became the world’s first Super Stock Car in the sevens – 7.98 at 174mph. This configuration made over 100 passes with only minor troubles. During the 1988/89 season USA chassis guru, Tom Alston, proclaimed Zap’s Rat to be the world’s quickest ladder-bar rear end car.

During the 1989/90 season, the HQ went faster. Zappia decided to progress from a big block Chev to a JP-1. John had to spin the Chev to 8,500rpm to run 7.9′s with a 5.1:1 diff. With the JP-1 he did not go over 7,300rpm and ran 7.3s and 7.4s with a 4.3:1 diff.

In 1988/89 the chassis was similar to the latest in US Pro-stockers. Not a bad effort considering that Zappia designed the entire chassis at home. John copied ideas from US magazines and then logically thought through the geometry. Many experts protested that the car needed a four-link rear suspension, but John felt the car would need to be modified too much to accomodate such a set up.

Consequently, Alston asisted John to improve the ladder bar suspension rather than replace it. Alston suggested that the single ball-joints were a weakness, so Zappia utilised double heim joints on the front bars with two diagonals also fitted forward of the rear axle assembly.


The chassis comprised a rectangular section main frame with heavy-wall chrome moly front down-tubes and sub-assemblies, with Spax coil-over adjustable shocks front and rear. The steering is rack and pinion while the roll cage is a full Funny Car style but right hand drive. The cage is a six-tube, head and shoulder encircling affair. Front brakes are Kawasaki motorcycle discs and calipers on HQ stub axles. Rear brakes are Wilwood four-spots.

John recalls, “At the first meeting of the 1989/90 season the car ran a 7.69 off the trailer. It was a radical change and caused such savage wheelstands that I had to back the launch revs down from 4,000rpm to 2,500rpm”. The JP-1 conversion resulted in a bigger 14-71 blower and higher compression. Using this configuration Zappia dominated the 1989/90 season with a best of 7.63 in the 2892 pound AA/Gasser and a 7.36 result in the 2620 pound BB/Altered configuration (while carrying 220 pounds extra weight for this class.)


The JP-1 displaced 482 CI by the use of a 1/2″ Keith Black stroker crank. Keith Black stage II heads using Manley 2.20 and 1.99 inch valves exiting gases into a set of Funny Car style pipes made by John. Venolia pistons and rods, Casale gear-driven roller cam, Crane overhead components and Manton springs complete the package.

The JP-1 used an Enderle 990 pump, Enderle magnesium Bird Catcher fuel injection system and a BDS 14-71 supercharger, overdriven between 44% and 52% using BDS drive components. The blower sat on top of an extensively modified Cragar magnesium manifold. The JP-1 produced an estimated 1400 BHP. The drive train in 1989/90 consisted of a three speed Lenco with a manual shifter, backed by a L&T three-disc clutch. The rear end was a severely narrowed Ford 9 inch with Strange components and 35 spline axles. The final drive ratios used varied from 4.3:1 to 4.8:1 depending upon track conditions. In the 1989/90 season, Zappia won the 1990 Nationals and was Drag Racer of the Year.

For the 1990/91 season, the JP-1′s cubic capacity was increased from 482CI to 526CI and fitted with new twin plug Veney billet heads and twin magnetos. In this configuration the engine produced 1700 horsepower. At the beginning of the 1990/91 season, Zappia had very specific aims, “we want to be running sixes at over 200mph before the season is out.”

John recalls, “At the first meeting of the 1989/90 season the car ran a 7.69 off the trailer. It was a radical change and caused such savage wheelstands that I had to back the launch revs down from 4,000rpm to 2,500rpm”. By 1992, Zappia ran sixes every pass and just got faster and faster. Racing against America’s Wayne Torkelson at Ravenswood Raceway, Zap’s Rat ran 6.80/208, 6.82/205 and 6.83/207. John, again, top qualified at the Nationals that year.

By 1993, Zap’s Rat weighed in at 1,224kg (2,693 pounds). The JP-1 was replaced with a Walt Austin Keith Black 540CI Hemispherical-headed monster producing 2,200hp using 12.1:1 compression and a high-helix 14/71 supercharger. A triple disc L & T slider clutch, a three speed air shifted Lenco and a Strange equipped 9 inch were used in conjunction with a Funny Car style solid rear end. John said, “If the car gets traction, it runs straight.” Prior to the 1993 Nationals, Zappia’s record stood at 6.78 at 214.28mph and he commented, “Here at Calder the car’s probably really leaning on it! The conditions would have to be perfect. It does 6.80′s easily.”


In 1994, John Zappia won the Australia vs USA Doorslammer Challenge 3-0 against Kurt Kuhns’s 1959 Corvette. Zap’s Rat ran 6.56, 6.57 and 6.62 at 215mph. This was also the year that John started planning the new Zap’s Rat II to take over from the original Rat. It was necessary to have a chassis which could handle the ever-increasing horsepower the engines were producing. Kim Soia was instrumental in organising the production of the new chassis. John visited the USA in late 1994 to arrange shipment of the chassis and to purchase new engine parts for the ongoing horsepower wars.


As it turned out, the new Statesman Zap’s Rat Series II could not be built for the beginning of the 1994/95 season so Zappia dusted off the Monaro and brought her out again. The Rat rose to the occasion achieving its fastest times and arguably greatest successes in 1994/95 despite many people believing it to be a spent force after 11 years of racing.

In the 1994/95 season, Zap’s Rat achieved 4 wins and 3 runner-ups from 10 events. Zappia was the 1995 Top Doorslammer Champion and using a 554 cubic inch TFX engine, producing 2,380, achieved it’s best performance of 6.54 at 218mph. Zappia was again top qualifier at the Nationals that year.


The final run Zappia ever made in Zap’s Rat was at the Winternationals at Willowbank in 1995. The Monaro ran a strong 6.60′s pass but burst into flames near the end of the track. Zap kept on the power to the end of the track and still ran 199mph.

Zap stopped the car near the fire truck. The first person on the scene was Victor Bray who dragged John out of the car. The trick front fibreglass panels were singed black but the car survived the potential tradegy. Two weeks later, John sold Zap’s Rat to Kim Soia of Soia Seminars.

Interestingly, while Zappia was racing at the Winternationals ’95, racers from Cairns, Queensland, were interested in purchasing Zap’s Rat. Their mention was to paint it red and keep racing it in enemy colours. Zap was not particularly happy about the car’s future in the East. Kim and John knew that if this icon was sold interstate, a famous piece of WA automotive history would be lost forever. Eleven years of blood, sweat, tears and incredible success would vanish. John was saddened by such a prospect but needed to sell the Monaro to finish the build of the Statesman Series II Rat. Kim Soia purchased Zap’s Rat with the view to keeping it exactly as Australia’s drag racing fans will always remember it – in its final aerodynamic nosed, huge winged, record breaking incarnation. Don’t be surprised if you see Zap’s Rat being raced in the occasional doorslammer grudge match in the future. You can’t keep a champion at bay forever.
