My guess would be:

335rwhp
340rwtq
12.7 1/4 @ 108mph

It'll be tuned by Sam88gta1

I think the thing that'll hurt me is my race weight - If my wife was driving, it might run a 12.5 - haha

pull the back seats, jack and tire, floor mats, all the **** in your glove box, loose change, and anything else that you don't need to go down the strip.

Thanks to Sam88gta1 for his work, perhaps next time I'll bring something a bit more challenging for you to work on

Sadly, the track decided to close for "cold weather" despite it being 50* and sunny today. I'm going to try and make it out to another track Sunday but may have to hold off till next year.
