If I remember correctly, you had to use 100oct fuel to run 12psi on the Stage II TT kit on Christian's car? So maybe slightly lower compression might help with staying on pump gas?

In a turbo application it is really easy to make up for the lower compression by simply adding boost. on the other hand in a SC application you are going to be limited by how fast you can spin the SC to make up for the lower compression .

Woot. Over 400! Good job GTM!

NYBladeZ · 02-27-2010, 04:30 PM

can we get another 2psi and get it up to 10psi?

G37Sam · 02-27-2010, 04:43 PM

10 psi on stock compression and pump gas would be on the limit of calling for trouble I believe

I'd say 10psi is the limit and it can definitely be done safely. Sam, you guys are doing great! Keep it up! By the time you guys get around to advanced tuning I should have a full exhaust and clutch/flywheel done awaiting a blower!

roplusbee · 02-27-2010, 05:59 PM

Awesome. The setup in the video is the stage 1? That fluttering was kinda crazy for a bit, but I guess that is how bypass valve go huh? I am feeling the temptation to come over the the dark side of the boost now, lol.

I think Sam himself said earlier in this thread that 9psi is actually conservative on 91 pump gas with the right tune. Scaling the numbers up, 9lbs should put down about 425whp...which is the magic number in my book (~500bhp!)

The top end hp numbers are good, but the TQ is extremely lacking, TQ is what powers you through turns, i'll say that whoever makes the most low end TQ between this and the Stillen kit, is gonna be the one who gets my hard earned cash.

How much torque are you expecting ?

Sunco 94, with an agresive tune by GTM @ 9lbs boost= about 425 RWHP on my car,.
11.7 1/4 mile time here we come.
There is more power to come yet, I beleive that this is a very conservitive tune. Just wait till he starts to tune it.
Sam thanks for the phone call today.
Your customers in Canada beleive in you.
and
Canada will win the Gold Metal in tommorrows hockey game vs the USA.

GO CANADA GO !!!!!!!

I'd like somewhere between 340-350.

DannyGT · 02-27-2010, 08:14 PM

LOL he's doing this on stock exhaust components...I'm sure he can come close to your TQ figures. Also, I plan on tracking the car but the last I checked you wont be spending anytime in the 3000 range. These power outputs so far as keeping in line with the motor as is except making a ton of more power. The TQ is more than fine so far. It should only get better.

With downpipes + exhaust + meth + 10psi and a very good tune (still safe) = this stage 1 should have no problem making close to 450whp.
