    What restricts the standard EM to Xbhp?

    What about the design of the standard EM restricts it to Xbhp (can't remember exact figure)?

      Any chance we can make that thread a sticky in the Engine, EM and IM forum?

          what a wonderfull EM is that prototype of the SQ...but why is it that it seems just about the same flow as the EVORS2??

            Because Lupo911 redesigned the flow of the EVO manifold to great effect, it outflows an OEM SQ manifold.

            The main difference is the longer runners and more even flow, better for high bhp output.

              yes i was just discussing this with him... if only the EVO RS2 would be made in a way that could accomodate even larger turbos than the GT3076...it is possible that the EVO can flow more than 500hp...

              I have my mind set on a holset and i have to figure out a way to mount it with the EVO(depending on the hotside i will use).Billman will be the guineapig for me...i hope!

                EVO will easily flow 500

                OEM SQ manifold run GT35R to 600 bhp, a EVO RS2 with better flow could support it.

                As you say thing is physically the GT35R won't fit to the manifold without a metal spacer, but then it would take it out of stock position.
