Re: The "4.9 liter turbocharger, stage 1" thread.

Just mentioning I am still kicking around, I pop in hear and look around every now and again.

My 4.9 is still running great, however I am now getting ready to install my 8th yes eighth transaxle. I managed to blow up the Centerforce Dual Friction clutch I had in the car as well. I have a new Clutchnet clutch that is suppose to be able to handle 450lbs of torque. I am building a custom one off 4spd standard transaxle for the car, with much better gearing for the 4.9's torque. It has a 3.32 gearset with a .73 overdrive 4th.

I do still have a turbo sitting here for the 4.9 but am not sure if I am ever going to get around to installing "it". I still plan a Turbo at some point however the turbo I have is way too big for the motor. It was almost a gag joke that I got it. Its from a Kenworth Tractor. Yes as in long haul tractor. So it should be good for uhm 20-30psi on a 6L+ V8. The inlet is so big, it looks like it could swallow a wooden 2x4 and spit it out the other side.

As for the Turbo 4.9 Fiero. It was modified a fair bit, however for the most part, the engine and fuel system was stock. Custom ECM, and such. I know he had A LOT of passes on that motor and nothing ever failed, it was actually built for his wife and she ran the hell out of that car.

I belive it was a high 12 second car IIRC. I would have to double check the records to make sure. I think there car was in the 3000lb range.
