overbore only DX SBO Olds build
#41
X2.
Gearman - your 12-13# of boost seems to be correct for a mid 80's GN. They peaked at 15 then rolled back to 12-13# so I stand corrected. But with that said you only need 425-450 crankshaft hp to run high 11's in a 3800# car, so they still didn't make big power in that form. Plus they had intercoolers and EFI, that helps a lot.
