1/4 mile estimate?
#11
On well prepped track those "junk" Pirellis have went 1.7's on mild cars.
Is that a M5? If so I would check the fuel filter and plugs (please search and read before you attempt the plugs). The traps are very low for 55F and 550' ASL. You are not doing anything to kill the mph like shifting to 4th and running the car heatsoaked are you?
Car is capable of around 13.2 @ 103 Stock (On Limiter in 3rd - 1.8 60'))
Car is capable of around 12.8 @ 107 CAI/TUNE (1.8)
Car is cabable of around 12.7 @ 108 CAI/TUNE/DS Track (1.7)
Of course that requires tip-top surface prep, outstanding air and a passable driver.
If its a 3.31 car add roughly 1/10 in ET +1 mph trap for a stock car and subtract 1 mph trap from modified cars.

Hey Gene K, since I did my cams, 4.10s and LTs, I'm all the sudden having to shift into 4th at the end of the 1/4 and I know its killing my ETs...is there some way to prevent that?? It makes it seem like you're saying you can but I don't see how thats possible?

What size tire are you running?

This is a little bit of a rant so I apologize . . .
Most of the time our cars get a chance to run at any track, there is little to no track prep done. So it will be hard for you to find the 60' the Gene is speaking of.
Afterall those mods I would still invest in a set of OEM 17" wheels and some DRs or cheater slicks. It's about a $500 investment.
They will help prevent your tires from spinning and give you better times. I've seen lots of people go into the wall with little to no experience because the spin the tires thru 3rd. Not that the OP is doing that with the time he indicated.
I hate seeing regular street tires at the track. The F'up any decent track prep that was there in the first place.
I hope after you get your mods you will hit the 12 second zone.

With 4.10 the best option would be a 28" Drag Slick. The flex and compression reduces loaded radius on launch while the tire growth on the top end lowers rpm.
PS that Whipple will pull 4th just fine!

With 4.10 I dont think you have much option. On street tires I would have went 3.73 Max and spun it 7000 rpm. Actually I would have just kept my3.55's
