with 270 you'll light those tires up till 4th gear. I know of a guy running a setup close to the one I'm going to have and it puts down 283whp. He can shift really light and not open it up all the way and break the tires loose. 12's with 270whp on street tires I don't think possible. I wish it was cuz I'll be putting down close to 300whp and would love to hit 12's on drag radials so if I could hit 12's on street tires that would be the ssssssssssssssssssshit.....good luck and keep us posted...you too Jan
