And to really break it down further. He'll reach 14psi at what... 3500-4000? I bet it's a fun car either way. But imagine making 14psi at 3000-3500? I'm sure that's a much more fun street car when you're spinng to 6000-6500.
It's not all about psi man. It has to do with the size of the turbo. Let's say you run a T76 at 14 psi and a S91 at 14 psi. Which one is going to make more power in your thought process?

The answer is going to be the s91 by a good stretch for the simple fact of how much more air it's moving. It's like comparing a Coffee straw (the T76) To a Big Gulp straw (the s91.) Stick that coffee straw on the end of your garage aircompressor and feel how much air is coming out on the other side. Now take the Big Gulp straw or something similar and put it on the same aircompressor at the same psi in the tank and see which one has more air come out of it and how freely it moves through.

Either way at 14 psi on either turbo on the street at 3500 rpms your not going to be getting traction anyways....

Just my 2 cents. Not being a dick either.

Also, I am almost certain that Kyle aka Na$ty-Ta, was not trying to be a complete dick.


Edit: I guess I should mention also that if you are not in the compressor maps efficiency range on the bigger turbo or even the smaller turbo, the opposite one at the same boost levels will make more power that is in it's efficiency range...

I can break it down many ways but to me it seams your stuck in your way of thinking and have never owned a turbo setup.
With a 370 and a S88 I was in boost around 3K and in full boost by around 3800. With a 408 like the people above I wouldn't be suprise if its not by 3500.
I'll know with my new motor and new turbo. I by no means see the S88 and S91 as race only turbo's. Now as for boost on the street I prob spin a lil more RPM's on the street then most @2700 @ 56 mph...... So when I floor it, iyd like instant boost.

They may be a ""Race"" sized turbo but work awsome on street cars and comes into another debate........ What makes a car a street car ha ha LOL
if its driven everydayin every weather its a street car LOL

Now the Bull **** attitude as you call it came from your first reply about why go with a T6 flanged turbo if its what YOU call a ""Street Car""
the way u put it and defended your self was as if the person who has said T6 Flanged Unit is not a street car. People take that kind of stuff as defensive even if u say u aren't being that way and didn't mean it that way. U make think his or mine for that matter aren't street cars. Thats fine in your eyes. Others will think different and thats theres and your right as having your own opinion. I was just explaining and defending his choice and mine. Do I view his Nd mi e as street cars that can and do get driven every day??? Yes I do. Would I drive mine across country or to the track???? Hell no. I have to much into it........ Plus the cage and kirkey seats wouldn't be so nice LOL

I wasn't trying to offend u. Just doing like everyone does on here...... Goi ing there .02

I think the T4 flange would be a problem, when you try to turn 6000-6500 rpm. That's going to be some serious back pressure. I think it would work, but maybe not the best choice for overall potential. The t4 would be a lot easier to package for sure. These big *** t6 housings take up a lot of room. Either way, it will be a fun car to drive. I would get my goals set for the car first, then decide on parts. You don't want to buy stuff twice down the road if you want more power.

You might have missed the part in the first post which said 390whp 367wtq was what it put down on motor before the kit was installed. 722 at 14psi is cool with me on straight 93.

Yes the S91 on a 370-400ci LSX based engine seems to work awesome. Makes stupid amounts of power and spools extremely well.

Which turbo would be better with the 408ci to make more power?

FI-98X????

or a 101mm?

It's always a compromise. Obviously, the turbo that pushes the most air will make the most power. Large turbo = slower spool, less streetable, harder to package. Smaller turbo = quicker spool, less power, more streetable, easier to package. I think we all can agree that streetable for some is not for others. The best thing is to have a clear ultimate goal and work from there.

So to put a couple of those advantages of each together, those two items being "larger turbo and a faster spool", you need to increase cubic inches to match the turbo, right? Isn't increased cubes the only way to spool a given turbo fatser?

So, maybe a 454ci with a 98mm or 101mm would spool like a 408ci with an 88mm or 90mm.
