Greychevy is now running 13.3's in a 4wd truck with stock 20's. ...
Damn Fast, but I don't think it was on 20's
Post on NA says:
"my old 4x4 rims that I gave to fasthemiram05 that had pretty worn 265 goodyears on the back and some kind of 235s in the front
.....not the best set up for the track but they hooked good"
"Stock 265/70/17s whatever that is....31s I think "
Still, so awesome for a 4x4!!! to be kickin ass against a bunch of 2wd's
==============================================
My best NA Run was in the early Spring , May 2011, 13.89/98.5 at over 2600' (DA corrected to 13.4/102) usual summer time DA runs about 5k+
RCSB 4x4 with 3.55's....only mods at the time were Airaid intake/ Magnaflow catback+ypipe/ Diablo 93 tune and 28" DR's
My Dyno with those mods (minus teh DR's) was only 309hp lol! , fourth gear pull that peaked at about 5600rpm on 32" Grapplers
Supercharged now likely over 500whp with water/****, but still looking for more next season
LT Headers, 4.56's and a DTT locker should be a good Winter project, local track closes for 6 months in about 2 weeks
