BF XR6 TURBO UPDATE - WE TURNED UP THE BOOST - SO WHAT DID WE MAKE?

[@farmer3242]

Iv just put an Artec t4 split pulse manifold and a Borg efr9174 on my fgx, it makes 441kw at 16psi on 98 octane, its very responsive too.

Gee thats a big turbo mate, I thought you might be able to make abit more with that size, thats on par with a G42 turbo - generally not very responsive down low, so your lucky if it is. Thats why I stick to small frame.

The efr9174 has a titanium exhaust wheel 74mm and its supposed to be really light weight. Has 750nm at 3k revs, 865nm at 3300 to 4300 then drops away to 750 at 5800rpm, peaks at 20psi at 3300rpm, holds till 5k then falls to 16psi. I have a 14psi spring in ts 50mm gate, im gonna try 17-19psi spring and get it retuned to try hold 18psi right through because we think gate is getting pushed open despite 95% duty cycle with mac 3 port. The artec manifold is a awesome design and looks to have great flow to wg and i think its getting pushed open.
