The S480 I have coming is a T6 with a 1.10 A/R. also I'm going to be using this valve that should make it spool something like a T3, .55 A/R, but still have almost full flow of the big T6 housing once it opens I've heard nothing but positive results out of these valves.



Here is some pics of a BW S400 vs. MPT76.

 

KB..that is the baddest thing i have ever seen. i did not know that they made such..i have heard of a procharger and somthing like that.. can you get that for a T-4. instead of using nitrous to get off the line, would it work better?

 

Sound Performance sells them but they want $500 bucks for them! I built this one for much less, but still wasn't too cheap. It will only work if you have an open manifold and a divided turbine housing. Zombie over on LS1 tech put one on his big remote mounted turbo and made a BIG difference in spool time, about 30% or so decrease in lag.

 

I have a S85 on my 408ci and I love it 744rwhp at 12lbs here.

 

how much would you make another one for???

 

now we are talking...

what tranny are you using?
when does it see full spool?
what does it pull to?
whats your CR?
what converter?

man just describe your whole truck please
what you like and dislikes

 

def. a S80-85 on a stroker but not a T78 T4 but a PT88 T4 will work because of it big turbine housing and its 4'' flang exaust... less back pressure

 

To a point, you're going to have to try different things and see what YOU WANT.... This hobby isn't cheap, especially when you get into the boost/stroker game... Swapping parts to tailor your setup isn't always easy or cheap. But at the same time we can't spoon feed you every bit of this information...

Learn to read compressor maps, try different stuff, and in the long run you'll be happier with your own personal setup. Its a much more gratifying feeling to know you built and spec'd something yourself and it works...

 

i understand buddy..

i'm just taking in knowledge is all

 

^^^^^^ this is what i am really trying to get info on^^^^^^
