I had done a search on the topic and stumbled on some links to articles that basically summed up that bigger is not always better as far as intercoolers go.

For a 6-8 psi setup which of the JRC intercoolers would be most approriate? Looking for a good balance of pressure/cooling for a daily driver.

 

6

 

t-3/t-4 sounds good, with a bar and plate intercooler

 

It depends on alot more then just how many psi you want to run. Need to know a little more info. Like what turbo, power goal, ect. ect.....

 

thinking about running either a t3/t4 57trim or a GT3251E

Goal is ~ 250-270hp at 7psi (daily driven)

 

like i said 6". At his original goal of 6-8 psi, it really doesnt matter what his power goals are. If you are only running 6-8 lbs the chance that hes retarded and gonna run a t88 turbo are VERY unlikely 250-300 hp you will be fine with te 6"

 

6"...can't go wrong with the 8" though it'll work just as good.

 

My 5 inch has been working fine for me. I would go with the 8 inch if I was you incase you want to build your motor in the future.
