I was at 530hp with 150hp sticks and a 62/65/12 but it could get warm.

 

what # would my 01 put down?

 

500ish....i would think...

 

94ttss, if your friend is running 37's you need to make sure he has at least 4:10's if not 4:56's. I have 3:54's in my truck and I had 37's on for a bit but couldn't stand how bad they made the truck lag. I didn't want to go to the expense of regearing so I went back to smaller tires. If he does twins for more power and his gearing is wrong the truck will still lag. Eric
