Pontiac G8 2008-2010 - Good night at the strip last night...

Good night at the track last night.....weather was mid 50*s and relatively dry, not sure of the DA but I would guess around -500 or so...crowded as hell and only got 3 runs....

Setup:
09 G8, Tires at 30 psi, Sport mode, manual mode in 3rd., 1/4-1/2 tank of fuel. 4165lbs raceweight. 1865 miles(first trip to the track was 460 miles)-this probably helped some also...

Run 1:
13.06@107.1 w/ 1.99 60', tapping the 6300rpms limiter about 50' before the traps. Off idle launch, just smoothly pushed it to the floor.

Run 2:
13.05@107.1 w/1.99 60', still tapping the limiter in 3rd. Off idle launch but pretty much nailed it on the last amber. Also removed the air filter on this run

Run 3:
13.13@105 w/ 2.02 60'. Left in sport mode and let it shift to 4th..(big mistake)....Stalled up to 1100 rpms and nailed it out of the hole...Spun the tires some....not bad but definetly some. Had a tad bit of hesitation on the 3-4 shift, definetly slowed it down.

I guess the problem I have now is, if I leave it in 3rd, it tags the limiter, shift to 4th, it slows down...If I could extend the limiter to 6500 rpms, it would probably be ok... It would definetly go 12.90s@108+

All in all, I am very happy with the car's performance and I am ECSTATIC with the gains I got from the Superchips tuner.....This is the only mod to the car and it took off 5 tenths and gained 3 mph, pretty much all from the tune. The weather was identical to my first and only other trip out, only this time I had 30lbs less fuel and the Superchips tuner... I HIGHLY recommend this tuner to anyone....

What was real cool was that on all three runs, I won.... I beat a C5 on drag radials with at least exhaust and late model GT mustangs...I know they all were hate'n it....

Freaking G8s are awesome machines. The chassis they have is simply insane.

Zeta baby. Gotta love it. Its like its on Viagra...stiff as fuck! Some nice ass times coming from a tune only car. Almost beat my record, and I mean almost. You had the advantage of far less fuel though.

Nice times! Where's your torque management/transmission settings? Put the fronts up to 50psi to decrease rolling resistance and run it with 1/8, just when the low fuel light comes on, and you just may knick the 12's.

I had the "shift torque" setting at 150% last night.... Although today I moved it back to 75% and it still seems to shift as hard WOT, just a little softer when normal driving.. Yeah I was really trying to get a 12 but.....the track was too crowded and I just didn't get enough runs to try different stuff or run some gas out of it.

The immediate problem is hitting the limiter in 3rd at 107mph right before the traps....if it shifts to 4th, it loses 2 mph....Not much choice other then let it bang off the limiter at the end....If I 60' better, I might get a 12.90 out of it but the mph will be stuck at 107....

This shit is really unbelieveable when you consider its MAYBE making 300rwp, weighs 4200lbs and runs 13.0s at 107.....comparing that to my Trans Am when it was stock going 13.0s@108 with 300+rwhp and only 3600lbs, and its a 6spd stick with more rear end gear...its crazy... I guess that new A6 tranny just makes it haul ass...:secret2:

Awsome, I just got my tuner yesterday and I'm very impressed at the performance. Mine ran 13.57 with just cai and cheap mufflers and now I'm pretty sure its gonna go low 13's for sure. It pulls really hard and doesn't loose the r's like it did with the stock tune between shifts. Its definetly the best bang for the buck. Gotta love it. Those are some great runs. I've seen some VMS tunes that didn't get where you are right now. Its very possible you will get into the 12's with the 93 tune thats coming.

Your making over 300 whp...i'd guess around 315.

If you update your tuner it now will support moving the limiter to 6700

I just received mine yesterday and I don't remember what the setting were, I set mine at superchips settings.

DAMN....thats good to know.... Right now, all I can do is raise the limiter to the "Superchips value" and that seems to be 6300rpms or so... I just updated my tune about 2 wks ago, is this change something they just came out with? Would be sweet if its true..... 6500rpm limiter would get me by....

Mine came with the latest updates and so, it should be up there. I just know that it is jack the bear and it goes to about 6300 without a hitch. I like it.

Good times and traps!!!!!
