No exact specs here but the new direct drive has fewer moving parts. (No jackshaft, rear belt & pulley, bearings, ect) I think it's a lot cleaner design. Two piece blower and mani allows for a one man install. Stock setup does not require the crank to be pinned but I did anyway for safety. Optional pinning kit is around $100.
I can tell you I boost 7 psi on the stock 98mm pulley and 9 psi on the 91 mm pulley. Stock cam, other mods in sig & garage. Should be around 600 whp? IDK.
No dyno yet as none are close to me. 4.2 sec logged 60-100 mph pull with HPTuners, stock was close to 6 sec.
