Add boost to what you have -- with 7 PSI you easily have 250 HP -- I had a 3 liter (2990) (4.060" x 90mm) and it was very difficult to keep it cool in SoCal driving it around. Maybe it you went 4" and keep the size down around 2500 it might live better. But I like the performance of a boosted engine a lot better...
Was it the outside temperature that meant you couldn't keep it cool or the install/design of the system ? With hindsitght do you think you could control it now.
I always presumed with enough oil coolers and fans you could keep an engine cool enough.
Mine won't have an oil cooler in the fanhousing (oil ways blocked off) but thought I could easily compensate with 2x decent sized, well placed, good quality oil coolers with fans fitted. Or am I wrong
I'm hoping one big one will work with a matching fan
