I'd also say its knocking, because thats what Hemis do.

Buy racing gas and try again.

Okay, lets even do more and make it simple. Make sure you have the best name brand gas you can find, load the 91 CAI TUNE and try again. Like Mikel said it is knocking. You may want to work on your launch and get the 60' time down also. That's all - simple - have fun!

[mikel]

yeah, thise 60' times are killing the whole run, look into some drag radials to take advantage of your new power!

What RPMs are you launching at????

[ricks]

First off, you need to tell us a little more.
Like:
Are the tires spinning when you hit the gas? If yes, how bad?
Are you putting the pedal straight to the floor or easing into the gas?
Automatic or stick shift?

[craigw]

Smoked the tires one time with the esp all the way off. Mostly just getting a chirp with the esp 1/2 off.
Tried several rpms. Seems 1500 is about right. I may be hitting the gas too hard. A tuner in St. Pete says ease into the gas.
If we get no rain I'm going to the track Thurs. night.
I'll let you know if it gets any better! The car still only has 1800 miles so it's not broke in all the way yet.
Auto trans. poor gear 3.08

[crf450rr]

When you get to the track let 5 psi out of your rear tires, do not drive through the water box with street tires, launch at 1200 rpms
and use auto stick (not "D")
High DA will also kill your times...
I was running 14.20s with my 07 Charger R/T in stock trim without the predator.
Now I'm running 13.30s on stock tires, a RDP CAI, 180 T-stat, Flowmaster Force II catbacks and a 91 octane CAI tune.
DA was around + 900...

[craigw]

Were getting our 4th night of rain. Maybe I'll get a break for tommorow.
I was planning to let some air out this time.
Not sure what DA is? Also when I shift the car, it seems like there is a much longer pause between gears?
Cross your fingers for the weather!

7 passes before the rain.
Best pass stock tune, 2.225 60 14.313 et 98.99 mph

I need a gear!

If you've not installed a 180 stat with coordinated efan schedule AND a catch can, install those.
