Rallimike is running the T3 .82, Adams is the exact same volute only with the T4 footprint. He should see roughly the same as rallimike's car. Give or take. The 15psi@3300 is exactly where the T3 1.06 runs on a well sorted motor. Sounds like the porting is done nice, I am assuming you got decent numbers?

ok, i got the car back this morning and i have been driving it ever since. the turbo spools stupid fast, prob as fast as stock twins, and the power feels AMAZING!!! i had no idea i would gain that much! Thanks to the Chris Sanders street tune the car runs Flawlessly! it actually runs better and smoother than with the twins, and my gas mileage is suprisingly better than with the twins too while running 850/1600 injectors! I really cant say enough about how pleased I am with the Quality of work performed by Banzai Racing! I would very highly recommend them to anyone!!!

btw my buddy is going to be trying to get together a dyno day at his school so I should have some numbers pretty soon!

What gear are you in when you reach 12 psi by 2,700-2,800 rpms? Is this logged?

That spool up is very impressive. If those numbers were not from the Peak Hold function, would you mind placing your Commander in Peak Hold mode for rpm(s) and Boost and performing a 3rd gear run to 3,000 rpms and posting your peak values for boost and rpms?

Thanks in advance

ok i took the car out today for a while and found a good place to test boost. with the new wastegate and no problems i get 15psi at 2850 and hold it all the way to redline in 3rd gear! it feels great!
before ppl fly the bs flag one of my buddies is coming over tomorrow so we can shoot some videos and i will get one with boost guage(steering column mount) and tach so everyone can see.

2850 that's amazing (400rpm's sooner then me). That may be more street fun then my 500R. I would like to see the video. When you dyno, I would like to know at what rpm's does the power fall off at to see what the trade off is for the smaller compressor. If you are at about 400rwhp then you can stay with a single plate clutch and your car will be extremely comfortable daily driver.

At what rpm are you flooring it at in 3rd gear to get 15 psi at 2850? 2000 or so?

Just hit the dyno, what will it be, 75 bucks? That's a drop in the bucket with these cars

i took a few vids today but the only one of a third gear punch for boost response came out blurry and my buddy deleted it, so i will have to get another one next time i take her out. here is a vid where i floored it from 40mph and had to let off bc a car went thru the intersection in front of me and scared the **** out of us(that ****** came out of nowhere!). anyways here ya go. ill make some more worthwhile vids soon hopefully.

Rpm's, boost and a steady hand with an antivibe camera would be better but still cool.

Looks great! I would love to see the dyno sheet with the boost value too... people always talk about how there cars spool up full boost at 2500 rpm, but I want to see it on a dyno sheet!

Keep kicking *** bigcox!!!!
