Good to know. I'm glad we finally got someone who is jot afraid to share info to spread some light on this subject.

It really is so easy to twincharge I don't understand why more don't do it. You have complete control of the supercharger bypass valve with HPTuners, so there is no need to give yourself a headache with compounding the boost.

His name was Jesse. He's not a member here or any other forum for that matter.

Exactly! For my Matrix project Im going to use the AEM FIC to control the bypass valve, Im hoping that will work well!

So the SKY is doing a compound set up, theres been multiply twincharged set-ups, why no bi-turbo set-ups?

Well not complete control.

The boost reduction table in 1st gear and remaining gears only starts at 4000rpms. So you really can't control the SC before that. At least that I am not aware of.

I think that is the main reason why ZZP recommends running a 256, 256et or 259et on their twincharge setups. Those turbos typically take a while to spool compared to the 252et.

So when selecting a turbo for a twincharge kit you really want to look for something that comes to full spool around 3750 rpms.

lets take turns and we all donate to each other and buy this kit just gotta pick straws on who goes first which I hope is me lol

The Sky is doing a bi-turbo setup.

Correct. I had the 4K RPM set to 95 then it tapered down QUICKLY to 0 by 5K RPM.

I like you.

Hes doing a compound build, unless im missunderstanding something and there the same thing. I thought a Bi-Turbo set-up was set up so the small turbo spools the big turbo, and compound basically switches from the small turbo to the big turbo after a certain PSI

Nope not me... haha Soon tho! Maybe 2 weeks? All depends on who can tune me and when

I'm going to be using a Holset H1E. Spools in the late 4k on DSMs. 60mm Inducer, 82mm exducer. Makes for a 53.5 trim. Directly comparable to the s362et. Should work perfect on a twincharged car. I got a lot of headwork also, and will be using zzp cams. God I can't wait to get back and put it all together.

When will you be able to get her all done?

haha ik you were talking about it thought i had 2 and 2 together

lol that is a weird coincidence. You don't see many twincharged threads around. I just talked to byt and he's gonna tune me as well. I just need to throw the good old blower and manifold back on first

Next summer, I'm stationed in Germany, and the car is in Nebraska. So it's going to take me a little longer than most cause I have to get leave approved to go home.

This is called a sequential setup like what the 93 rx-7's have for thier TT setup.

I know the guy pretty well. He lives about half hour from me. I saw him friday night at a little meet and when he took off it sounded like a rocket with that dump tube. The car is stupid fast. I plan on doing the kit over the winter. Prolly going to be the only 2 kits in NY!
