do you actaully need all 4 valves? seems like some of this can be cut out in order to reach the same goal.

Waiting on that dyno yo.

I wouldn't try to redesign it for better spool I'd give it a bigger engine if the current one is not able to.

We use 3 outputs from the AEM for the prespool, main exhaust valve, and air control valve. The wastegate is controlled by a traditional electronic boost controller.

1000whp itself isnt practical for daily driving . twinscroll turbo with a shot of nitrous is the way i would go if i owned a supra.

sometimes i think people forget that doing something new, creative, and original is FUN. when you do this stuff every day you have to try new things to keep yourself entertained and you ALWAYS learn a bunch in the process.

sometimes people dont want the cookie cutter set ups that everybody else has.


to trying something differnt....even if it doesnt go as planned (hopefully it does), and even if it is "impractical"

Alot went into that.

I would hate to be the one installing that thing.
I would imagine there's a very specific sequence to do it in.

i just want to know why you didn't run an e-cut to open and close off the second turbo? it would have been easy enough to make a controller that would let you change the boost level where the second turbo kicks in.

Most likely because this selenoid and valve could stand up to the pressure and heat better is my guess, because it's pre-turbo.

i'm thinking they did and had problems with carbon build up. works on diesel, but not on gas cars.

It spools MUCH quicker!! We have 19 psi by 4000 rpms!! When I run the twins in non sequential mode we dont see 19 psi until 6800!!

The dyno that I posted compares our sequential kit at 23.5 psi to a GT42-76 mm turbo at 27 psi!!

Props on doing something new and innovative....
I was wondering how long it would take to catch on. This is something that has been employed in quite a few new diesels and if properly managed works very well. Again,

New? In what respects? Also, where is the torque line ? Why are you guys leaving things out in each post ?
