remote mount turbo questions
#21
I cant believe this that 88 cant feed a 408 good god man put a 100 on there holy ****! more in that setup? Have you thought about some smaller gears like 3.23 youve got enough tq to push em would probably lower et?
just a thought.
The more I think about it Id like a 402 with a 76 but I dont want to bust out the cash for a built short block, tranny and turbo. Do you think a 6.0 bottom could hold up to high boost with just some rod bolts?

didnt you say you had a 76 on your 408? How did it feel on the street?
Another thing where do you shift at? What sort of cam are you using?
trturbo:what do you mean when you say punched out?bored over? I noticed the compression is lower than stock, did you do that just with bigger CC heads? Transmission? 650-700rw is what i need to get where I want to go. Hows about a dyno sheet on the 5.3

This is not the bigger dyno. It is before the forged internals and just a start on tuning when it was still a 5.3 with LS6 cam only.

Another Mopar guy chiming in. You Chevy guys with the turbos on built motors are making some very impressive power. Very cool!
My STS set-up comes with a GTS-76. Lag is so minimal for me that it feels like a S/C engine. I'm making 550 rwhp and 590 ft/lbs with a super flat torque curve on a very conservative 5 psi (stock Gen III Viper engines have cast pistons). We're going to bump it up to 8 psi w/ methanol as soon as STS finishes up the twin turbo C5 Z06 install. I'm expecting about a 75 rwhp increase. In my case the power numbers are mostly limited by the stock parts in my engine. I understand that the 76 will easily support upwards of 1,000 hp.
