PICS























there is a lot of room for further improvement on this setup with very minor changes. as soon as the madness of SEMA passes and things settle again we'll get to work, make more power on this turbo, and then put the BorgWarner on

 

Dyno sheets and pictures of the kit?

 

the car is literally coming off the dyno right now! coming very soon

 

Well I am speechless. Time to get another credit card.

 

Why only 18psi on pump? Why not bump it up and get more pwr? Ppl running 35R setups make more than that on pump. It seems you are sacrificing the drivability and not reaping the benefits.

 

we are in az, the worst 91octane pumpgas ends up here, cali and new mexico. no point in pushing the limits of crappy gas just to put bragging rights up, particularly with 15 gal of Q16 sitting there.

no drivability is sacrificed whatsoever, considering that its spooled by 4200rpm and there is no change in spool due to the 91 octane vs Q16

 

What kind of Dyno and what correction was used? If you dont mind me asking.

 

spooled = full boost?

 

Thats a ton of tq. and spooling by 4200rpms=tons of street fun!

 

Running the 2.4L how high are you revving?

 

should have a decent powerband.

 

Nice numbers

 

nice numbers Geoff....
I hope i make near these figures with my setup...

on my car at 5600ft there is no way we spool it so quick.

pls post mods....
what cams etc..

 

jeez, you guys do amazing things with that 40R.Is that a 4094R?

Congrats I can't wait to see the powerband in that thing.

 

Geoff, do you have any dynoplots of a twinscroll 30r and 35r 2.3L stroker?

i am looking to upgrade my kit in the future but i want full boost (say ~27psi) by no more than 3800rpm like it is on my car now
