Peppy's Build Thread

[bjc]

Pity the custom exhaust manifolds cost the earth!

Are FG different to B series exhaust manifold Ralph?

[k31th]

Yes, the B-series is different to the F-series turbo exhaust manifold. The FG one flows better.

[Ralph Wiggum]

Yes, and universally regarded as flowing better.

[Skids4kids]

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.

Hey Peppy, considering you've been having traction issues, have you thought about finding a hub dyno to jump on?

[747pwr]

Hey Pep, I have a spare FG exhaust manifold you can have mate - just pay the postage and ill ask you stupid questions when I build the ZF haha

[Peppy_t92]

I think there's one local fifty one, but the dyno time is good for myself and the operator, were both learning

747, if your not going to use it, I'd be more then happy to purchase it from you for research and flow testing.. but if I'm going to start changing manifolds I'll be making up a tubular one, to sit a gtx45 on

[MattyP]

why gtx45?

[747pwr]

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

If Pep's research heads down the tubular manifold path, i'd be quite keen to get my hands on the FG manifold.
