The drive by wire throttle delay on the late models definitely make consistent launches difficult to say the least.

I raced my brothers completely stock 2010 Challenger R/T (Hemi, auto) in the Street class at Monster Mopar Indy last fall the best run it did was a 13.62 at 102 mph.
I made it to the Qtr finals before getting eliminated.
The car ran about a half second off the dial in on the last run.
I'm not sure why (wheel spin or what) but it the car ran about a half second off the dial in on the last run (But the mph was still 101).
Ahh well, I thought I did pretty well for a car I hadn't driven before driving it up to Indy.

I drove it there, raced and then dove it home which was fun and simple.

A pic of my brother and his Challenger.

I have a 2012 GT500 that I use for a daily driver, but I haven't had it to the track you. I just bought a TVS blower for it today. That should make it a little more fun.

010 R/T, modified, lowered, love it. No races yet but it is my DD. 48K miles so far.

I bought an 03 Cobra a few yrs ago. A "few" boltons and it has 615hp at the tire. Fun car.

I drive a 2009 Dodge Challenger R/T with a 5.7 Hemi.
Nice car, I love it.

I just bought a 2012 SRT 8 Challenger that seems fun but I have only had it a week.we will see

Bought my wife a SRT8 Jeep and did it up with all the usual bolt on (cold air, headers, exhaust, throttle body, programmer). Fun car to drive all year round even when it is snowing up here.

Here's my 08 srt...had since new with only 13k on it now!!!

A little stroke and a little boost.

The R/T uses a composite intake manifold. For better throttle response, ground the TB to the engine block. A couple of other tips when using a drive by wire TB in bracket racing is to disconnect the battery between rounds so the factory PCM adaptives don't have a chance to take over and you'll run more consistant. I've also tried shutting the engine off and restarting it after my burnout which then puts the PCM back into closed loop startup for about 20 seconds or so. Going for fast times I leave the line from an idle. My short times have always been faster this way vs loading the converter, but my reaction times ain't pretty lol. When I leave off the converter my reaction times are always the best and I run way more consistant and brought me home some paycheck's.

Would pulling the #2 fuse do the same thing as disconnecting the battery? It clears the PCM. Curious if your car is a M6 or A5. Do you run with traction control on or off?
