Good to see this thread, keep everything civil and on topic and I'm sure there'll be no problems.

EFR - 1.05 divided

GTX - 1.06 divided.

everything else was the same, just turbo change apparently. No too sure on engine details.

Ahh S50 engine, thats why is spool so great

Nicks has the speed sensor installed but the road rage gauge was faulty. If it doesn't get fixed soon the speed sensor will go straight back to the ECU.

I might do the speed sensor in the next couple of weeks

Hey guys, how's the speed sensor coming along?

This popped up on the Borg Warner facebook page.

EFR 9180 making 960ps - on pump fuel in japan....

 

[Piggaz]

Pretty crazy 34 that. Exhaust straight out under the passenger door! It had a T51 on it before the 9180.

Thats Kenneth's car

The 88mm is a +1500hp turbo, 9174 is a good street replacement though. I'm keen myself but no one is showing any turbo speed logs.

[Piggaz]

Not sure what to make of the 9174. It might be a bit of a 2871 thing going on. Too much compressor, not enough turbine.
