WE’RE always excited by a new build, and Daniel Szabolics’ twin-turbo 632ci HQ sedan is no exception. The car has the crank out upwards of 3500hp and run into the six-second zone on a 275 radial, and Daniel has his sights set on Street Machine Drag Challenge 2019.
Daniel explains the journey that led to his HQ’s ballistic Dandy Engines-built twin-turbo powerplant. “I initially had my heart set on a 632 with an F3R ProCharger,” he says. “We made some blower brackets to get the ProCharger down low rather than have anything bulging out of the bonnet, and all that seemed like a good idea. Then I contemplated a front-mount crank drive, and after unsuccessfully trying to work out how that stuff would fit in the front of an HQ, I decided to go the twin-turbo path.
“I had been watching the Pro Street scene for some time and had been really impressed with the success of the Dandy Engines team, especially Frank Marchese’s XW – wow, sevens on a 275 radial in a 3600lb car! I could tell they really knew what they were doing, so I gave him a call. I told Frank all I wanted was a cool streeter that would run a seven-second pass; Frank laughed and said we could do that with a plug lead hanging off!” Daniel has owned the HQ for years, part of a collection of cool rides he has accumulated. “I always liked hatchback Toranas, HQs and HK coupes,” he says. “I was lucky enough to have bought all three back in the day when they were not worth anything. In the case of the HQ, it was a local car from here in Albury-Wodonga.
It’s been in the build for the past eight years, but I guess I’m my own worst enemy as I keep changing my plans.” But the plans for the build are now set in stone. The boys from Dandy have completed the monster mill and it’s down to minor fabrication work and finishing touches to get it up and running.
The twin-turbo 632ci Dart Big M mill in Daniel’s Quey is good for a cool 3500hp. Will this be Drag Challenge’s first 6sec car?
“Initially I was a little concerned about the size of the engine,” says Dandy’s Frank Marchese. “This thing is going to make a ton of power and it’s going to hit a 275 really hard in the first 60 feet. Daniel already had a lot of the parts so we really wanted to go with what he had. In this case we have ended up with a 4.6-inch-bore Dart Big M block with a 4.75-inch-stroke Callies Magnum crank, Oliver rods and Diamond pistons, and with AFR cylinder heads.
“For this build we have gone with a set of Precision Pro Mod 94 turbos with Precision wastegates and blow-off valve. In an engine that was 100ci smaller we have made over 3000hp, so this combination is really as nasty as you will ever get in a street car.
“We are going to give it a shot with this combination, but we are prepared to build a smaller short motor, somewhere around 500 to 530 cubes, if this thing is too brutal.” The mill uses a Peterson R4 externally belt-driven oil pump with a Jesel belt drive on the cam and T&D 1.75:1-ratio rockers, with cam specs around 275 on the intake, 288 on the exhaust and 114 lobe centre.
Fuel supply is from a rear tank to a Weldon belt-driven 16-gallon pump and a Bosch 044 primer pump for starting. The combination will run on E85 on the street and alcohol at the track.
Each runner of the billet CNC-machined Plazmaman intake manifold is fitted with a 250lb Siemens injector and a monstrous 700lb Billet Atomizer injector controlled by a Weldon regulator. Just to put the level of this build into perspective, the manifold runs around $7000 and a set of those 700lb injectors are roughly $5K!
THE nitrous boys are going ballistic after American racer Jamie Hancock recorded an incredible 3.599-second eighth-mile pass at Tyler Crossnoe’s Outlaw Street Car Reunion in Kentucky. Hancock’s Pontiac Firebird has been in blistering form lately, and this pass made it the first nitrous car in the 3.50 zone.
The car left on a .894-second 60-foot, which is mind-blowing in itself, and clicked off 198.17mph over the eighth.
However, in a last-minute upset, Crossnoe had to disqualify all the runs at the event, after copping mounting flack that the timer system at the track may have had issues.
RIVERINA local Brett Piltz is set to debut his tough-as-nails hatchback Torana, following a four-year build. The Torry has had a serious transformation since Brett purchased it from the late Mark ‘Tubby’ Diessel. In typical form, Piltzy kicked the rods out of the roller-cammed small-block in a burnout comp and since then has poured a ton of money into the car.
The 440ci small-block Chev boasts the best of everything and was assembled by Vintage Racing Services in Wagga. On the dyno, the aspirated combo cranked out a massive 860hp, and Brett intends on giving it a little spray once he gets a handle on it.
The motor is backed by a Mike’s Transmission Ultimate Powerglide and Gear Vendors overdrive, and the rear end has also been upgraded with a Strange housing with a Strange bolt-through Ultra case.
Piltzy’s main goal is to make Street Machine Drag Challenge at the end of the year, and is hoping to run a bottom nine in full street trim and well into the eights on the spray.
THE lads from Stuart Bennett Smash Repairs in Orange, NSW are closing in on their goal of having Australia’s quickest LS-powered car after running a PB of 6.71@209mph in their stunning Pontiac. The current record stands at 6.58 over the quarter-mile.
The Pontiac is the ex-Darren Parker Pro Stock car, which Bennett bought 12 months ago after racing an LS-powered Camira. The car is powered by a twin-turbo, 427ci Dart-based LS Next II motor with All Pro LS7 heads, Bryant crank and Carrillo alloy rods. The engine runs on alcohol, fed by an Enderle 17gpm pump and eight 500lb Billet Atomizer injectors, and is currently seeing around 40psi of boost, which puts the motor at about 1700hp. The magic figure to go a 6.40 or better is 2500hp, which they hope to achieve with a pair of 88mm turbos at some stage soon.
“The turbos are maxed out at the moment,” Stuart says. “Up to 30psi of boost we have good air, but after that it’s garbage.
“It’d be nice to be in the 6.40s to be competitive in Pro Elite, so that’s where we are aiming,” he says.
To keep the compression sealed, the block has been fitted with a receiver groove to accept the Dandy sealing rings.
The monster mill is backed by an M&M TH400 three-speed with a transbrake on first and second gear. The Mark Micke-built trans also comes with a matched M&M converter.
The rear end boasts similar-quality hardware, with an RC Metalcraft-fabricated nine-inch housing with a Strange Ultra Case centre, floater housing ends and 3.25:1 gear ratio.
In the world of big-horsepower radial-tyre cars, it’s all about chassis and suspension, and Shane from Marshall Speed Shop in Geelong has been given the task of making the car work.
“I’ve really just taken over the work that was done on the car around eight years ago, and in that time a lot has evolved in suspension,” Shane says. “I’m just trying the get the car up to a modern standard with additional bars and chassiswork throughout the floor.”
Other jobs include a removable ’chute mount, setting up the rear suspension with an antiroll bar, fitting a rear crossbar to mount the Santhuff shocks, a removable lower engine containment tray, and a whole lot of extra bar work – a lot of which will be bolt-in in case Daniel ever wants the car to go back to being a bare streeter.
“The car already had a fabricated floater rear end; I have just upgraded where the shock mounts go and have run a bar off the lower control arms to stop them spreading or moving out,” Shane says.
At this point there are just a few small jobs left, like fitting an SFI fire system, before the car returns to Albury-Wodonga to have the hot side on the motor completed.
“We hope to be testing by mid-June,” Daniel says. “At one stage I suggested to Frank that I get on eBay to buy a nut-stretcher; I’m sure he got my joke. just need to get comfortable in the car, make some passes and then pull it down before we have a crack at Drag Challenge.
“I don’t want to put a number out there,” he continues. “I’m not wanting to talk myself or the car up at all, but I’ll say I’d be happy to finish and it’d be great to run with the top dogs.”
But although Daniel is tight-lipped about the car’s potential, the Dandy boys are pretty confident about its abilities. “This car is heading for the 6.70 to 6.80 zone once we get it ironed out,” says Frank, the reigning Drag Challenge champion, who has decided not to run his XW this year in favour of getting Daniel’s car sorted.
“This guy has fire in eyes,” he laughs. “I reckon he can drive no problem. As I creep up on the tune, he will creep up on his driving.”
From where we stand, if the stars align, Drag Challenge has its first real six-second contender. When you look at the quality of the the car record and the books. talent behind s it, this HQ is set for the record books.
