Are FG different to B series exhaust manifold Ralph? Link to comment Share on other sites More sharing options...

The FG one flows better. 1 Link to comment Share on other sites More sharing options...

Skids4kids in the mid....not the bum like some Member 609 Member For: 11y 7m 27d Gender: Male Posted 04/08/15 06:52 AM Share Posted 04/08/15 06:52 AM I have the FG exhaust manifold on my B series but haven't tested it back to back with B series manifold using the 6466.The shorter/smaller diameter runner length on the FG manifold would lend to faster spool but at the cost of some up top as the B series one has longer/larger runners.Application will determine which one flows better for the individual.

747pwr Member 68 Member For: 13y 9m 9d Gender: Male Posted 04/08/15 02:15 PM Share Posted 04/08/15 02:15 PM If you are saying why not something in between, on paper the gtx45 will "only" flow another 200hp more, Wouldnt be worth changing potentially turbo, manifold and waste gate, screamer or plumb back, oil and coolant lines, intercooler piping and intake, heat protection etc andddddd why not try crack 1000 With the amount of boost and e85 used pretty much anything will come onto boost quick enough Link to comment Share on other sites More sharing options...
