MSD VS FAST For LS2
Getting a A&A supercharger installed soon. I was thinking with all the work that needs to be done to get the kit installed might as well go a little farther and have a blower cam and intake installed? I see posts about the MSD being far superior than the FAST but most posts are for LS3 & LS7 not the LS2. I personally think the MSD is ugly as sin but will look past the aesthetics if there are real substantive gains. If we’re talking under 10 Hp difference then I’ll eat the difference and go FAST. Can you chime in a post your experience with either FAST or MSD and preferably with a blower motor. I have a Si Trim Vortech Heritage Compressor with a 4.0 pulley 🙄 F’ing California. I’d like to get upper 500’s at the wheels with intake and cam. I plan to run higher octane gas, not corn 🌽 something like 105. Any insight is appreciated.

The gains from a non-ported LS2 intake manifold vs non-ported Fast etc in an FI set-up are minimal and not worth the $$ IMHO. Plenty of people making forced induction 800-900whp on a stock LS2 intake manifold. Not to mention Fast has been know to fracture at higher boost levels (ask ECS owner about his experience lol).
Save your money on an FI car and apply it towards a flexfuel set-up (if it's avail in your area) or some other beneficial upgrade to the drivetrain or fuel system..
