carbs i would use draw thru (can't run high enough boost through a blow thru
carb setup)
EFI defenitly use blow thru
my mates run a L20 draw thru twin 175 CD's and 34 psi
uses menthanol for cooling (detonation)
He's thinking of going down the EFI road
and changing it to a blow thru EFI setup (with intercooler)
