The White Car

Tremayne Brown's Fox is no frills, and all speed. He's that guy who doesn't say a lot, and doesn't have to. His cars are fast and dirt cheap.

"I started turbos with a '70 Monte Carlo in 2003," says Tremayne. "It was a gen-one small-block on a blow-through with an old stock turbo from a 12.7L Detroit Diesel. It was big."

Tremayne was into the car with a friend when the other guy bailed out. He bought all the parts and installed them on his Fox Mustang.

"For the water-methanol, I bought a garden sprayer and used a Snow Performance nozzle," says Tremayne. "But that wasn't enough. I added the garden nozzle that came with the sprayer, and that was enough to frost up the intake on 20 pounds of boost hot lapping it all day long."

This wasn't a turnkey combo. Tremayne went through several blocks by cracking the lifter bores or simply splitting the block down the middle. "This was the cheapest way to have fun," Tremayne says. "The thing should be able to run 9s all day—it's whether or not the block will hold up. I drive it daily, even in the winter. It cruises on the freeway and gets good mileage."

The garden sprayer, diesel turbo, and big tank are gone now, but the ideas are still there. Tremayne has been working with the carburetor to get the A/F ratio safe and deliver enough fuel to make power using the BorgWarner S475, 75mm turbo. The engine is still a basic small-block Chevy with a mix of TRW and Speed Pro pistons (his words) and iron heads. The cam is a solid flat tappet, but he didn't seem to want to share all the specs, or maybe he doesn't care—boost fixes small camshafts and a host of other shortfalls.

Tremayne's technology is slightly behind Derek and Brian, but that doesn't mean his car isn't fast. He is estimating 800 hp and 700 lb-ft and has a huge bank of gauges so he can try to control the car. "On the freeway at 70 or 80 mph and you hit it down, it will smoke the tires," says Tremayne. "So I need to warm the tires to race it at 20 pounds." If you want to find out exactly how fast the car is, you'll have to find him on Snelling Avenue.

Tech Notes

Who: Tremayne Brown

What: '89 Ford Mustang

Where: Vadnais Heights, MN

Engine: The current engine is a gen-one 355-inch small-block Chevy with a one-piece rear main seal. It's been rebuilt with Summit Racing rings and King bearings, otherwise there are a lot of stock and older speed parts. The heads are iron Phase II from GM Performance's distant past with torque-to-yield head bolts. The intake is an Edelbrock Victor Jr. with a Demon 850-cfm carburetor using E85. The whole thing is fed by an Aeromotive A1000 fuel pump and a 75mm S475 BorgWarner turbo.

Transmission: The Mustang uses a GM Powerglide with a 2,600-rpm stall and a TCI transbrake. Up on the cam, the converter is more like 5,000 rpm, but the car doesn't blow through it at the track.

Fabrication: Tremayne is a CNC tubing bender by day, so he knows something about stainless bends. Richard Brown and Jon Solomonson helped get the exhaust and other race parts together.

Suspension: The stock four-link hasn't changed; he just added new shocks and some homemade Heim joints for some strength. The front struts are 90/10s.

Rear: The 8.8 has 2.75:1 gears and 33-spline Strange axles.

Wheels: In the front are Weld Draglites and in the rear are Center Lines. The meats are 28.0/11.5-15 M/T ET Drag.

Interior: The dashboard is "cardboard and Bondo." The carpet is "gray with black footprints." The paint is "what's left of white."

Awards: Three moving violations.

I have been reading car craft for ever. the fact that there is little to no chrome on these cars has merit and that this is all done inexpensively gets my vote.  I have read a ton about turbocharging and other car stuff  for that matter and the articles almost always cost thousands.  these cars are done ok and look cool for daily drivers/racers and I would be just as proud to be the owner of one of those and I would any hot rod. this is what was the norm back in the 50s and 60s(innovation and recycling)  and has been missing from car craft and other magazines. I hope this and other magazines can do more articles like this in the future.  thank you and thank you to the guys who built the cars.

Lol slant 6 better than an ls I've heard it all now. All of our turbo cars in that issue have been at least a full second and a half quicker than that and all are stock motors.
