if you want something simple, inexpensive and ideal for auto-x with faster than stock spool - our stock location EFR 6258 kit would be my recommendation. we are about to release a 2-bolt lower manifold that would work great with this also.

the other option worth consideration is the EFR 7064 twinscroll iwg, that would be a bit larger but still acheive your targets and goals. both of these are in stock right now, pretty rare for the EFRs

agreed the 6258 is a 44lb/min compressor so it could do 400+ as long as the engine can breathe
