Here is the DA starting at 12pm noon. Cant get any better than this. Water grains are only at 10.2 and 00.0 is perfect. The track altitude is 1178 ft. To get a better DA than this you would have to go to the north pole lol.

temperature: 32 deg f
uncorrected barometer: 29.202 Hg
humidity: 38 %
vapor pressure: 0.180 Hg
dew point: 12.487 deg f
grains: 10.2
air density: 102.916 %
density altitude: -987.557 ft

What wheels are you using?

EDIT: I should probably read stuff twice.

EDIT#2: Something I CAN ask without feeling stupid, what width and offset do your wheels have? I've been searching for 5 spoke forged wheels but it's slim pickings.

Nice times! I guess that tune (and the weight reduction with the skinnies up front) are the biggest factor.

The 390 gears have to get a lot of the credit. I would kill for those 60' times. My best was 1.772 when I ran 11.279 @ 119.18. Great setup for NA car. Tell me your launch secret. :)

had several 1.66 to 1.68 60fts prior to the gear change...no secret, about 1000 rpms or so at launch. 16 psi in the rears and let the car do the rest.

Great runs! I'm nowhere close, but it gives me something to shoot for.
