My Night At The Track (Time slips!)

[Maxx Mazda]

Went to the track last night with a few buds. The conditions were about as bad as you can get. 25*C, 85% humidity, and get this, a 5,900' Density Altitude! My friend's Whipple charged Cobra on slicks normally puts down 11.8's but he could barely break 12.5's last night. Best I could do was 14.2 on 16psi. I was running my "slicks" (bald street tires on a second set of rims, inflated to 16psi) Everyone was running bad, so I wasn't that dissapointed. Check out my 60' times compared to the trap speed. If I could get the damn car to hook up, I'd be mid 13's on a good day. I tried everything I could. Started at 10psi, then in 3rd gear hit 16, and still not. Anyways, the Cobalt SC I was running had a stage 2 with smaler pulley and tune (stage 3, but not the GM stage 3) and hoosier slicks. On the final run, I ran 20psi, but had my overbosot fuel cut set to 18 (dumbass) so I hit fuel cut halfway down the track, and then on 18psi anyway my clutch packed it in. Driving home if I gave it more than half throttle it slipped, so now I've got to change that out... Anyways:

Run 1: bad R/T and launch says it all

Run 2: Missed 2nd gear (GRIND!!!)

Run 3: Not bad, still couldn't hook up

Run 4: Best of the night, still fighting for traction. Left it at 16psi for the whole run.

Run 5: Fuel cut, and clutch blew out. Still kept the time as good as I could.

Oh ya, to put it in comparison, 2 stock C6 Vette's ran 14.4 and 14.6 respectively last night. I can honestly say that I had no idea that conditions made THAT much of a difference...

Nice! I didn't realize conditions made that much of a difference either. It does feel quite a bit different on various days.

So you got your motor fixed already?

Get those 60' times down and you'll be lookin' real good! Drag radials or slicks on the horizon?

What clutch you running?

 

[Maxx Mazda]

Spec Stage 2. It's only good for 280 lb ft and at 20psi I'm making close to 350. Those 60's are terrible. I just couldn't grab traction at all.

Slicks are on the horizon. Must be nicve in Vancouver too, I wanna race at sea level and see what this car can do! Calgary sucks for that...

I am actually very disapointed with your times...My Speed with a Boost Controller and Catless j/Midpipe put down a 14.07 @ 103....
And that was on a hot day here in ohio.
It dynoed a whopping 178HP to the wheels.

Come to Calgary and run. We're at 4000'

Ya man, but like I said DA for that night was 5800' (un-heard of!) It just and I mean JUST finished raining in the area when tech started...
