TweekedGT said:We had 2 500rwhp LS1 Firechickens running 13.00 last night at our track, timeslips show 99% humidity. Both were running Vortech superchargers with over 20lbs of boost (So they say). What elevation are you at? That can make a big difference. 12.00 sounds pretty good to me. Probably have some traction issues too. Do you spin through first or second?
Procharger95 said:Yes on the Nitto Drag Radials 1st and 2nd were just there to give me enough movement to get into 3rd where I finally hook. My 8th of a mile time was 8.0 @ 90mph. It has been a while since I did this but I was just thinking back today at how much power the car made and the fact that I couldn't ever get the car to show what it was truly capable of with a good 11 or 10 second time slip. I even laid waste to a few 03 Cobras beating them by multiple car lengths that should've been mid 12 second cars but I couldn't ever get that kind of launch at the track

I think the trickiest part is launching hard enough to get moving without annhilating the tires and if I launched to soft (losing time) then I would have to worry about not annhilating my tires (losing more time) when the boost kicked in really hard around 4000-4500 rpm. It's been a while now since the car was running, it was just something that has always bothered.TweekedGT said:Have you tried launching at idle and feathering it out of the hole? The procharger has an increasing power curve like a Vortech I believe, so as more rpm is achieved more power goes to the ground right?
If I remember it right it was a 1.96 60ft time but the wheels were spinning until 3rd I think. It has been a while and the block is broke now and car is history but I'm bringing up spilt milk and regrets now till I get an 03/04 Cobra (sorry for the poor sentence grammar police if any are readingI_AM_CANADIAN said:what was your 60 foot time?
NoNOS said:According to your mph, you should be good for low 11's once you have everything figured out.
A calculator I tried out has you at 543 RWHP....is the weight you gave out including yourself? Thats the only thing I can think of.
And theres alot more to getting traction than just tires....proper inflation, shocks, springs, control arms, bushings (polyeurothane spec.)and tweaks to the front end play a major role as well.
Even adding weight to the back like a couple bags of sand can make a big difference. Once you can get your 60 fts respectable, an 11 sec. timeslip is inevitable.

brownbrosperf said:The Mickey Thompson drag radials will last about a week on the street. They are down to the wear bars after 2 weekends at the track, ULTRA soft. And besides that our car didn't like them at all, shatty 1.8 60' with wheel hop,switched back to ET Streets and went low 1.7 and no wheel hop.
