I always imagined the key with the 1000hp turbo setup with big cubes to help give the power before the turbo came online.

I remember going from the 75/83 to 80/96 turbo. Truck was seriously doggy around town and lazy to come into boost. But good god, once the turbo came online up top it was a riot. At the track it was irrelevant of course, just brake boost and go. With the smaller turbo it was the opposite, boost came on fast and fun, but up top it was a snooze fest.

03sierraslt, I think you're seriously at a disadvantage with the heavy truck and small cubes. At that weight, you will be quick with 1k, but it's not going to be blazingly fast. 10 second truck, but most likely soggy around town and maybe slightly faster than a stock z06.

Nah. I did a BB 454 with my dad, it's in a Chevelle with a two stage shot and it's fun but not my thing.

Well when you find that unicorn of 1000hp, snappy as hell down low, and has an awesome top end let me know!

No doubt, I know best of both isn't gonna happen but it's still fun to discuss.

I think there is something to say for CR, cam, heads and intake choice and their effect on spool time and feel out of boost.

So for a single is a s480 the consensus? T6? What wheel would be a happy medium?

Single is easier to fit but twins don't have to look cluttered. It's only 1 more turbo, air filter assembly, waste gate, down pipe, and oil lines.
One pitfall many builds get into.
"I want X horsepower now. But I plan on building a bigger engine and then I want xx horse power. So the turbos increase in size and are over sized for the current build.
Build the kit for the goal.
If you want 1000 build for 1000 not 1500hp.
You'll be way happier while driving it.

Rick, do you have any more pics of how stuff is setup on the twins?



Figures, I was very close to welding a fitting into my oil pan a couple months back before installing motor and just capping it. But I didn't. Oh well. If I do this I'll change my cam so dropping the pan is not an issue.

I'd like to see more with the twins as well! A cast manifold for twins would be the *****... just sayin.

While we are on the topic, what factory manifolds work best for that? Anyone have input?

I say look into quick spool valves too.

I built two kits using CTS-V manifolds. Fit is pretty good, easy assembly, and all the benefits that a giant chunk of iron lends to durability.
