Boosted Bowtie's combo pretty much says it all.

4450 pound truck. 383 with a standard cover 87mm turbine S480.

[email protected] mph.

1000-1100 hp @ the crank to run that number at that weight.

I can divulge this number, 5.6x at 128ish on a 1.5 60ft on a 347ci sbf in a fox at around 3450 with a driver, maybe a tad heavier, never scaled that car. I have seen one put up low 160's all in however, but thats using a bullseye s480 race cover model with t6 hotside. Both cars had the bullseye race cover turbo, the sbf ran a 1.25 ar hotside with a 87mm turbine if my memory ain't to fuzzy

Allot of power if that was your question. I know there are some people that have been faster, but thats from vehicles I can talk about.

306ci Fox body @ 3348 weight, S400-80 billet with race cover and 92mm LDP turbine wheel, T6 1.25A/R, went [email protected] Same car with cast 82mm wheel upgrade went [email protected] 2 weeks ago. Boost is not dropping off and back pressure is still in check. I figure the customers car with everything but the kitchen sink will do 135-137max with the 82 and 133-135 with the 80 if he had pushed it. He is working on the converter to get the car off the line harder.

Damn I hope my 306 s400-80 combo works That good. I've got a 1.25/ar but with a 87mm turbine. You know what heads are on this car and cam specs?

Is your T4 or T6. AFR's I believe are on it. I can find out for sure though.

imho there is no reason when starting from scratch to not go to the t6 flange turbo. package it nice now and make it all fit so down the road all you might have to do is put a bigger exhaust housing on.

6700 and I cant remember the seat pressure. I set it up like a Renegade car. Run a solid now and a slightly better head now. With some good sixty footers I look to run 20's this year. These turbos work great. with the 5.3 you should do well.
