Circle Track Race Car: Modifcation Questions?
Hi guys i race a 2000 Dodge intrepid on a high banked 3/8 mile oval. Kinda base rules for the class is v6 automatics FWD. A few things about the car it weighs about 3200lbs. We have to run a DOT street tire. The best tire thats legal that we run is a Good Year triple tread. Right now on my new motor for next year i got my heads off and the block is torn down bare. Getting ready to have it hot tanked in the next couple of days. I am doing a bottom end rebuild. (Crank, bearings, piston rings) and replacing all gaskets. Planning on opening up intake and exhaust a little. The big thing that i think will make a noticable diffrence is opening up the throttle body. I was talking with a friend and he said see if one from another vehicle will fit and work that is bigger. I was thinking is opening up some. I have never done it a friend that has built engines says he has a mill you could do it with, but i was thinking that you need the flap the same size otherwise your going to idle at high RPMS. Any suggestions while i do the rebuild on performance increases?
Also i need a right rear spindle/ knuckle. The bolt that goes threw the lateral links and spindle is stuck inside on mine. I need to get it out or get anther one so i can make both lateral links adjustable. I am open to any suggestions to help the performance.
