Just wondering if the times I am running are correct for the mods I have,
My car ran a best 13.14@112xxmph and was running 13.2's between 109 &111 most of the day. On street tires by the way.

Mods are; Comp cam XR265HR-14 212/218 (pretty small) 918 springs, comp extreme energy lifters,MSD 8.8 wires, SLP LT's & 3"y-pipe, borla cat back, under drive pulley, SLP lid, & 4:10's. Stock tune.

I was actually hoping to get a 12.9+ @114/115 with this set-up.

What would it take to break into the 12's on street tires.

yeah that's about right... need to know your 60' though. That's where it's at for most M6's.

Best 60ft was 2.111, on my best run it was 2.164

Eh... whats your elevation and the air density where you live? IMO you should be in the 12.9's with just Longtubes...

Elevation was about 350ft. Haven't been able to raise my rev limiter. Could this be holding me back?...What about an ls6 intake?..would this give me my 2 tenths?

Is the car tuned? Your 60' isnt that bad for street tires, but could still use some work. Heat the tires up pretty good. Also make sure you let the car cool down between runs.

The car still has stock tune. I have a diablo programmer and have been undecided about uploading the programmer tune. Would there be any harm installing this tune with aftermarket cam.

thanks for help.
