If you're running twin 4" downpipes, you better have a lot of cubes between those turbos. Your average 402 iron block won't quite cut it. I vote for a single 101. If you can't make 1500 on a 101, you probably shouldn't have the turbo to begin with.

The real question is are you interested in dyno numbers or going fast? You don't need 1500hp to be "stupid fast"(of course it helps).

 

Yeah I'd say anything over 1000 will get you into a "death wish on the freeway" situation in just a few seconds.

 

Yeah...but it can't hurt I know about the LT1 that made 1000rw with a ptk kit and a 355 w/ stockish heads. But...i bet if he could fit it, he would use a 4" dp.

 

With maximun effeciency like awesome flowing heads, A2W intercooler, proper gearing, effecient converter and propoer tuning making 1500 rwhp with a 94mm is not impossible. I plan on making very close to if not 1500+ rwhp with my 94mm turbo. It not just the turbo!

 

This is going to be a full drag cor so the power is for the track only. I have done some research and it is not the right time to go boost because of the extreme cost of things to do it right....im 19 in college .....I think im going to go ahead and do a 408 with some etp 265 cc heads and nitrous pistons with a 200/200 nitrous set-up and a big solid roller. Im thinking i can get around 1000rwhp with this if done right. But thanks alot guys for all your info I will be back in a couple of years when 8's arent enough for me anymore

Thanks for the thread though.

 

I'd say go with a 96 or 98 mm if you only want 1500 rwhp. I think you would be close to the limits of the 94 mm.
