I am sorry Magnuson but this is a TERRIBLE idea..... Our motors cost over 11K new and you have not long term tested this on any vehicle.... not a good idea...

Actually this is one if the strong points of a DI engine, the ability to handle low octane fuel and run high static compression ratios. The LT1 is designed to run on 87 octane fuel, so it has plenty of margin for low boost on premium fuel, with or without an intercooler.
The Magnuson non-intercooled kits run a 10mm smaller pulley to provide less boost and have been thoroughly tested and calibrated to ensure that there is no danger of knock.
It is a very good entry level system that delivers similar performance to a full head, cam, intake, header install. When combined with a water injection system, can provide performance that rivals the intercooled systems in the market and the kit itself is fully upgradeable to be intercooled.
