Default Re: Track cooling recommendations

the thick core dewitt and ron davis radiators do a great job

run a dedicated bigger oil cooler If you upgrade to the high quality radiators that can stand the pressure, you can get rid of the bypass for sustained 6k plus rpms

I figured with the radiator upgrade there had to be a way of minimizing the effect of the bypass or eliminating it entirely, but every thread I found was full of conflicting info and no real definitive answers.

do some searches on posts from Tyler Townsley He did some very good write ups on the bypass and removing it.

If you spend LOTS of time above 6000 rpms and have a rad capable of the gpm flow and pressure, I think eleminating the bypass makes sense.

GM spend a ton to save a cheap @$$ rad, doesn't make any sense!!!
