I just bought a pair of t60s because the t70s I have would probably have been too big.

Im just trying to get an idea of what kind of response to expect from these. its a 5.3 with a 230/234 cam so it will be able to rev to about 7000 no sweat but plan to keep it to 6500rpms.
fuel is e85 or e98 not sure yet

so, when do you think

min boost rpm?
max boost rpm?
maximum power potential on a 5.3 ls and at what boost level?
will two of these go 8.50 on a 5.3?

any other input?

Don't expect it to spool fast, maybe 4k??? you've got a 1000hp of turbo on a 325ci motor.

as long as it spools faster than t70s Im fine.

here is another question though. does the compressor side have anything to do with spool time? or is it all turbine side? reason I ask is the t60 and t70s have the exact same turbine side. no difference at all. will spool be the same?

Here is my 5.3 motor I built for my twin 60-1 kit. I'm hoping to shooting for 700 whp. I built knowing that I was going to have a ci challenge. I need to change the turbine housings to atleast a .58 since the .81 are going to be to big for this 5.3.

Depends on your psi goal. you can reach full boost by 3k if your goal is only 2psi. Sry i've been in a smart *** mood all day. Anyways what are your goals, and what is it going in?

I prob wont be able to answer the question, but with those details someone else will.

You sure would think so, that 4.3 v6 with the S400 I got from Gus in his Sunbird was at full boost at 5000 and thats a much smaller engine with a big *** S400. Hurry up and get it going I want to see what a 5.3 with those does, should be good stuff.

Isnt this a drag car? How about a 4500rpm stall converter and a 2 step. The 2 steps are crazy how good they work.
