Which is better intercooled turbo or non intercooled turbo? There are kits out there that have both. From information i have read, is that you don't need an intercooler if you dont go above 14 lbs boost. Planning on installing an Aero 66 on a 09 D8. HM turbos makes a kit with water/air intercooling 240 HP, The other kit 220 no intercooler and lighter. Only planning on running 10-12 lbs boost.
