New Best last night

60 - 1.781
330 - 5.038
1/8 - 7.719 @93.24
1/4 - 11.903 @115.54



Mods are: K&N FIPK, Bjorla catback, 2.93 pulley, and HBH tune. Along with a plethora of IRS/suspension mods. Nitto's at 16PSI.

Both runs were a launch at 4,000 RPM's.

There is no visible belt dust at all, both runs were clean (though I do lift gas at every shift). So I'm wondering where did my MPH go?

Nice times! Seems like everyone is getting there best times in the last few weeks because of the weather. Thats not too un commen about looseing MPH though with a faster time. It all has to do with 60ft times. My first time at the track with just a 280 upper, Intake and a tune on BFGs I went 12.3 @ 120 and last time I went a few weeks back I was only able to hit 117 on all boost but still had a much faster time than before... So I duno

I duno your 60ft was pretty good but Im sure you could get a few more tenths out of her with a better 60ft on slicks. but then you would be pushing the drivetrain pretty hard and most cobras dont like that very much
