The sound of producing 856 turbo-fed rear-wheel-horsepower in this low-flying sleeper ’02 T/A brings to mind a jet fighter

2002 Pontiac Trans Am - Sonic Onslaught

While at first glance this ’02 T/A is easily recognizable as having rolled off a GM assembly line, a peek beneath its vanilla wrapper reveals a level of modification with style that Pontiac would never have been allowed to achieve. Tim Conneway’s Bird hides a nasty, growling turbo LSX engine poised to pounce on anything on the road, the track, or at a show.

The 46-year-old owner of Gulf Bindery has always been a serious car guy. When he found out that ’02 would be the final year for the Firebird, he had to have one. Since his search began mid-model year, his pickings would be slim. “I wanted a white, six-speed WS6 Trans Am,” he says. “There wasn’t a single dealer near me that had what I was looking for.” Finally, in May of 2002, he located one in Orlando.

 

Humble Beginnings

Within the first year, Tim began modifying the T/A. “The plan was to keep it mostly stock with a cam and a few bolt-ons,” he explains. “But after hanging out with a bunch of my Cobra buddies making 500 rwhp with just a pulley and tune, I became a little let down with my naturally aspirated setup.” It wasn’t until he took a ride in his friend’s street-legal, 8-second turbo Mustang that he knew he had to go turbo.

Tim had a number in his head—800 rwhp. Luckily, he knew of a well-qualified shop to help him with the build—J&J Performance, located in Cape Coral, Florida. “There were quite a few local forced-induction cars Justin Nelson at J&J built,” he says. “But unlike the rest of those, I wanted to maintain pump-gas freedom and my A/C.”

Trying to make over 800 rwhp on pump gas is no easy feat, but Justin and Tim set out to make it happen. Over the next four years, Tim went through four engines before finally opting for the cast-iron, six-bolt LSX block. The stock block couldn’t hold the heads down with 15 psi of boost being shoved into it, but the six-bolt configuration on the LSX block has had no trouble at all.

No filter under this lid!... 

   

 This is where the Snow Performance water/meth kit sprays in Tim’s detonation deterrent.

Hameetman Racing Engines in Ft. Myers performed the machine work on the GM Performance Parts block before handing it back to Tim. A set of 4.125-inch CP forged pistons fill the bores and feature a 5cc dish to help lower compression. They are attached to Crower 6.125-inch rods and a Crower 3.50-inch crankshaft—final compression calculates out to 9.5:1 and displacement is 374 ci.

Tim went to Total Engine Airflow to order his six-bolt Trick Flow 235cc CNC heads. On a 4.125-inch bore, the heads are advertised to flow 344/276-cfm at 0.600 lift. A custom set of exhaust manifolds feed into an 88mm Garrett 47/88 turbo that rests in front of the driver-side tire. Justin fabricated a pair of manifolds and plumbed the piping from the turbo into a Precision Turbo PT1500 air-to-water intercooler to cool the intake charge before it makes its way into the 90mm FAST intake and throttle body.

To help Tim achieve his power goals with pump gas, a Snow Performance water/methanol kit using a reserve tank keeps the engine from detonating. A healthy dose of 93-octane is delivered from the factory tank by a Magna-fuel Pro Tuner MP-4304 pump into 95-lb/hr injectors.

Outside, the Trans Am is bone-stock... 

    The Trans Am is bone-stock Arctic White. Tim has a battery shutoff lever in his bumper for his rear-mounted battery. On the street, the lever is removed and a body-colored plug covers the hole, adding to its sleeper quality.

For the cam, Justin concocted a custom, solid roller from Comp with 270 degrees duration at 0.050 and a lift of 0.640-inch on a 117 LSA. Crower shaft-mounted, 1.7:1 roller rockers obey the commands of the solid-roller cam, and operate the 2.080-inch Ferrea titanium intake valves and 1.600-inch stainless exhaust valves.

Once the exhaust has done its job inside the turbo, it’s evacuated through a 3.5-inch downpipe where an exhaust cutout awaits the flick of a switch to be open. When it is, the symphony produced by the engine is in guttural tones, and, as Tim has experienced, catches most people off guard with just how menacing it sounds. For more reserved street duty, Tim closes the cutout and allows the car to breath through a B&B after-cat. Under full boost, however, he has actually expanded previous mufflers, so he doesn’t hit 15 pounds with it closed.

 

Holding the Power

 

There is little indication that you’re looking at a turbocharged, intercooled, 374ci LSX engine. To further the illusion of a stock appearance, Tim smoothed down his FAST intake manifold and painted it matte black. The alternator mounting location had to be raised to clear the way for the turbo’s exhaust routing.

Tim knew he couldn’t expect everything in his Pontiac to hold up to the abuse of the monster mill. Justin pulled the T56 out and installed upgraded gears from G-Force, including new overdrive gears because Tim didn’t like the ratios on Fifth and Sixth. An Exedy triple-carbon fiber clutch was installed and offers a tremendous amount of grip without killing Tim’s left leg or driveability. Gears are selected with a Hurst Performance stick. A custom 3.5-inch Dynotech Metal Matrix aluminum driveshaft extends back to a Moser 9-inch with 3.50 gears and a 40-spline spool.

Getting the power to the ground was a project in itself. Up front, the factory control arms and K-member were replaced with BMR’s lightweight tubular units. The steering system was upgraded with a Flaming River shaft and a Turn One pump. QA1 single-adjustable struts and shocks were installed, along with Eibach Sportline springs, and BMR’s 36mm front sway bar and 36mm rear sway bar with Extreme Anti-roll kit. A BMR Extreme torque arm and adjustable Panhard bar, G-2 subframe connectors, and Spohn tubular lower control arms round out the suspension upgrades.

 

   

With the front bumper removed, the turbo setup is revealed. The air-to-water intercooler not only provides more effective cooling, but its smaller size allows Tim to hide everything, giving no indication that the Pontiac is turbocharged.

A set of Baer 13-inch front and 11-inch rear brakes with drilled-and-slotted rotors sits behind a set of 18x8 and 18x10 BBS LM wheels. Tim went with Nitto NT555 tires up front in 245/40R18 and its drag radial brothers in a massive 305/45R18 out back. The combination gives a sinister rake to the Bird.

 

Dialing It In

 

The stock interior was good enough for Tim, who added oil pressure, oil temp, water temp, fuel pressure, and boost gauges from Auto Meter.

As is standard with most forced-induction setups like Tim’s, the car was converted to run on speed density. Justin dialed the stock PCM in to provide a well-tempered street machine with a nasty personality when agitated by Tim’s right foot. The rollers were screaming as Justin finished his pulls—the Turbo T/A made an astonishing 856 rwhp on 15 pounds of boost. “The block and car will support 20 pounds of boost when I get tired of 15,” Tim jokes.

 

So what do you get after four years of hard work, trial and error, and spending lots of money? Well, it gets you one of the nicest street-driven Fourth-Gen Trans Ams in the country. With around 15,000 miles showing on the clock and an air-conditioned garage to keep it in, the T/A looks like it was purchased from a Pontiac dealer yesterday. Inside it has perfect carpeting, silky leather seats, and a new-car smell. Outside the paint is blindingly white without a hint of swirl marks.

Tim feels that he built a great car, and who can argue? He would like to enter it into a competition where cars are judged best all around. “I really think the car would do well in a competition that involved some road-course driving, street driving, and dragstrip passes,” he adds. With a best pass of 9.90 at 145 mph and a 1.63 60-foot, it’s getting the job done on the top end.

    

 

The A/C and fully functional CD player were retained.

Tim has expressed interest in participating in a standing-mile event, too. “The car is geared to have a usable Fifth gear, and the lower 3.50 rear-gear ratio means I should be able to get the car over 200 mph in the standing mile.”

So, if you see Tim in his T/A, it probably won’t be for long—he blows by with tremendous force and the sounds you may associate with a jet fighter.

 

 

Nitto NT05 Drag Radical Vs. ET Street Radical II Tires - Drag Radial Shootout!

Super Chevy Compares Nitto's New NT05 Drag Radial Against Mickey Thompson's ET Street Radial II.

Hot rodders have been searching for stickier street tires since Louis Chevrolet squeezed a blown LS9 his Type C Classic Six in 1913. From day one, engine technology has outpaced tire technology and the game has always been to get a starting line advantage over the guy in the next lane.

Enter the NT05R. It's got a far more aggressive tread pattern, a specialized race compound and large contact patch. It is DOT-approved, but is designed for the serious drag racer. Nitto has aimed the NT05R squarely at the modern muscle car market, including late-model Camaros and Corvettes. It ranges in size from 275/40R17 all they was up to 31535R20, with five other sizes in between.

 
 
 
 
 

1999 Chevy Camaro SS - Bait & Hook

A '99 Camaro Draws In Prey With Striking Good Looks, Then Dominates Them With 9-Second Passes

The LSX community, although quite large, remains a very intimate and close-knit group of enthusiasts. From time to time there are "rogue cars" that pop up, seemingly out of nowhere, run fast and then disappear again. However, for the most part, if you look close enough, you can watch a car coming up through the ranks as we have for a couple of years. Such is the case with Tommy Herrschaft and his '99 Camaro SS (although he probably didn't know it). Starting with a stock car and developing into a beautiful 9-second street ride wasn't done overnight, but according to Tommy the fun was in the journey, not the end result.

"First it was bolt-ons, then cam-only, then heads, then nitrous. After I broke a lifter, I had to build a new motor, which led to this current combo." That combo is built off of an '07 LS3 block, which has been punched out to 416 cubic inches by Scoggin-Dickey Parts Center. A 4.00-inch Callies Compstar crankshaft spins a set of matching rods, which hold tight to a set of Manley -10cc pistons wrapped in Sealed Power rings. SDPC also installed a set of ARP main studs over the stock main caps and ARP rod bolts before shipping the short-block to Tommy, where the rest of the engine was assembled. Motivating the valvetrain is a Comp Cams camshaft with LSL lobes, which features 247/254 degrees of duration, 0.623-inches of lift on both the intake and exhaust, and a 114-degree lobe separation angle. Sixteen TrickFlow 7.450-inch pushrods actuate the Harland Sharp 1.7:1 roller rockers that reside in the TEA/Trickflow 215cc LS1 cylinder heads. Milled to 60cc, these heads give the motor a final compression of 11.5:1, perfect for the nitrous.

Done with the motor and power adder, Tommy began fortifying the rest of the drivetrain. A Fidanza two-piece flywheel mates to the back of the crankshaft, which is bolted to a McLeod RXT clutch and pressure plate. When engaged by the Pro 5.0 shifter, a built T56 sends power down a 3-inch Strange driveshaft to the rearend. "Justin Nelson upgraded small parts in the tranny (pads, forks, slider, etc) but we are still using the stock gears and mainshaft." Out back sits a Strange S60 rearend, stuffed with a set of 4.10 gears, 35-spline axles, and a Power Lock posi. Depending on where Tommy is, the axles either turn a pair of 17x11 ZR1 wheels wrapped in 315/35/17 BFGoodrich KD tires or a pair of 15x10 Weld Prostars wrapped in 28x10.5 M/T ET Drags.

It also looks good enough to show up most cars on the road, as Tommy has taken the word "immaculate" to a whole new level. The factory black paint has been polished to near perfection, along with the factory wheels being so clean you could almost eat off of them. Up front sits an SLP grille, which helps clean up the front end and pull your attention upwards to the factory SS hood. When open, the hood reveals a show-quality engine bay, which has been meticulously painted, polished, wire-tucked, and cleaned. A subtle true-flame paintjob on the FAST intake draws your eyes to the polished nitrous hard lines heading to the plate and polished throttle body. Out back, below the factory SS spoiler, are a pair of Corsa exhaust tips, which are welded to an SLP dual/dual exhaust. Not only does the exhaust look great, but it sounds even better thanks to a set of 1.75-inch QTP long-tube headers and a custom Y-pipe. A subtle (well, as subtle as a 416ci motor can be) tone just barely gives away the 9-second beast that lies beneath this beauty. Unfortunately, by the time most people figure that out, it's too late, which is exactly the way Tommy likes it.

1987 GT Michael Saponara: Daily Special

Did you order 700 hp and a hot pizza to your door in less than 10 seconds?

Michael Saponara & His '87 GT

Michael Saponara was the first car in line on Saturday afternoon when the cars began their three qualifying passes. He was still there after all the cars were done. At 3,440 lbs with driver, Mike’s 9.08, 8.97 and 9.09 worked out to a 9.052 average, which was certainly more impressive. While no one else had times that were even close, Mike was actually very lucky to make it through all three rounds. He had a tire go down at the end of the last run and was lucky to even make it back to the pits.

Mike’s 1987 GT used an A4 block bored and stroked out to 347 cubes with a set of Oliver rods and CO 8.5:1 pistons topped with Trick Flow Twisted Wedge heads. Boost came in the form of a Precision PT88 turbo, which can support up to 1,250-hp. Backing the engine is a 2-speed Powerglide with an 8.8-inch rear holding 3.55 gears and Mark Williams 35-spline axles.

What makes this car particularly interesting is the fact that he still runs factory A/C along with stock power steering and brakes. It’s so street worthy; he even used it to deliver pizza from the Italian restaurant he owns. Mike has since won three out of the last four FFW Gainesville events and plans to hit several more before the season is out. His goal? To try to break the FFW True Street 3-run record average of 8.98 seconds.

Hats off to Michael and his great running 1987 GT!

Drag Radial
Watch out for Michael Saponara


Sep 12 2007:   Congratulations to

 Michael Saponara & J&J Performance get their drag radial car running better than ever. Michael runs a Pro Line Racing 427ci built engine with a pair of twin Precision PT-88mm turbos.

After making some test passes, Michael got his car to run a new best of 7.68@185.95mph! Not only did he run that fast, but he did it weighing in at a heavy 3520lbs!

How about these numbers:
1.27 - 60 ft.
3.37 - 330 ft.
5.02 - 660 ft. @ 150.35mph
7.68 - 1320 ft. @ 185.95mph
