My 1988 Mustang Lx Notchback Twin Turbo V6 3.8

I haven't been to the track yet, but I know I can't stay in the throttle on the street, it skates all over the road. 

This pic was taken the wat I usually drive the car. I don't change anything when I go to the track, except for rear tire pressure.

Small Burnout Video, no power braking, into 3rd gear.

Original set-up{The car has A/c, power steering, power door locks and windows, cruise control, tilt steering wheel, and an automatic transmission. The fuel injection system consists of a walbro 255 in tank pump, with 50lb injectors feeding the air charge.There is a second fuel pump mounted on the frame to feed methanol through a single 150lb injector located just after the throttlebody.}
Air charge is handled by twin IHI RHB52 turbo's. These came stock on 87-88 Thunderbird Turbocoupes. The turbo's are fed through home made headers. Boost pressure is 18-19 psi, which is maxed out for these little turbo's. The heated compressed air is sent to the intake which incorporates a liquid intercooler, also home made. There is a 7 gallon reservoir in the trunk to hold the ice/water mix.

The interior of the car is custom, it has leather '02 vert front seats, with matching material rear seats. The rear seat is formed around the powder coated roll bar.

The door panels are color coded to the dash and console.

I mounted my cruise control switches in the ashtray, since the factory SVO steering wheel didn't have switches.

The shifter is a console mounted B&M Hammer shifter with a C4 conversion kit. The car is so quiet at the track that I had to mount a shift light on the steering column because I couldn't hear the motor rev with the helmet on. The shift light, as well as engine management rely on a TEC3 system. There is also a switch on the console to arm the 90 hp zex nitrous. I used the zex dry kit and modded it to a wet kit. I purge the system into the 4" mandrel air intake pipe, that feeds fresh air to the turbo's through the passenger side fender well. The TEC3 also controls a 2 step that is activated when I hit the brake pedal. When I release the brakes, the 2 step goes of, and the nitrous goes on, thanks to a couple relays and some wire. The 2 step on this set up pulls timing to 6 degrees atdc, allowing the car to build boost on the line without the use of a transbrake.

The suspension uses coil-overs front and rear, with Lakewood Drag shocks in the back, and KYB struts in the front. The rear control arms are Mac, fastend to a 5 lug converted 8.8 with 3:55 gears.

 The front arms are tube lower from Hal, joined to a Hal K-Member. 4 wheel disc's stop the car from the 1320 assults. I originally started this car with the intent of having a daily driven 10 second ride, and the goal finally came to reality in May of 2006. The car ran 10.91@123.33 mph with a 60' time of 1.554. I weighed the car the next morning, and had a race weight of 3565 lbs.

New set-up uses a pair of TO4E 57 trim turbo's. I originally used the same intake system, but my intake/intercooler combo developed a pinhole. Since it was all 1 piece, I scrapped it and built a new one. The new one has a removeable upper plenum. I changed the injectors to 95# units, and used a pair of Tial 38mm waste gates. The car has good street manners, and doesn't overheat in traffic. I removed the a/c from the car, since it is just a toy now. I plan to remove the evap case from the dash and do some rewiring for the TEC3 and the onboard pc system. I still need to buy an lcd and a wireless keyboard for it. I saw a keyboard the will mount on my visor, so thats my plan for now.

While I had the motor apart, I rebuilt the C4 trans, adding  a bunch of Performance Automatic parts including a roller kit, a billet servo, a 6 pinion planet, a hardened input shaft, and a manual valvebody with a brake. I also had the torque convertor loosened up, but it could still use another 1000 rpms. The motor is a different beast at 4800 rpms, so alittle more stall is in order.

I had to change the rear control arms, I squeezed the bushings out of the mac ones. I went with Lakewood lift bars, and adjustable uppers, all with solid bushings. I used reinforcing plates on the lowers. 

 I used an electric smog pump(top left or left photo) for an evacuation pump, it only runs under boost. The right pic is my upper intake before it was welded together.

Heres a close up of my intake. I have a 75MM tbody. Right side photo is a shot of all the turbo coldside plumbing.

I use a 150 lb injector to spray straight methanol, to help cool the charge. I found this custom mounting bung on ebay, and would highly recommend it to any one needing more fuel.

A word about the fuel system on this car. I am using two 255 lph pumps in the gas tank. I added a "tee" to the stock fuel rail. 1 pump is staged, only working under boost. I have 2 5/16 lines for the supply side, and 1 5/16 line for the return. The alky system is also boost activated, and uses a bosch frame mounted pump. The fuel system is amazingly stock, no fancy rails, no 1000 hp pumps, just some creative efforts on my part. I use a wideband O2 sensor, and the car doesn't run out of fuel.
