I think we can all agree that turbo size and wheel design doesn't matter, because 20psi = 20psi no matter what turbo you run

well, obviously that's the case. The difference between the 2560 and EFR could be attributed to a little more humidity or a little lower ambient temperature on the two different dyno days.


The noobs have been right all along!

otherwise they'd have to use inferior cooling, like an air/air intecooler

Sure, my point/questions though:

1) Why aren't the 6258 cars romping on this particular 2560 car?

2) Why isn't the record breaking 2560 car mopping the floor with the 6258 cars now that is has a magical 6758?



Or did thenuge24 answer it?

Then there's this, just to **** everything up even more.

I don't even know what's real anymore.

315WHP and 251TQ at around 12PSI (179kPa)


323WHP / 262WTQ @ 14 PSI


There was a problem with my manual boost controller in the second dyno. I could have made more power. I'm now running EBC.

Maybe what he thought was a GT2560 was actually a GT2860?

Or it could be the larger 2560, I believe I have one in my garage.

Well, this car is back to try to make m0ar power out of the EFR. We'll see. I am hopeful for the car's owner because I want nothing but success for him.

This just in: FM doesn't know how to read a compressor map. Whoa this 2560 makes just as much power as this other, better turbo when it's outside of it's efficiency range. WHOA

Well the EFR car came back with a new external gate (internal gate was sealed) and a 4" exhaust. It didn't make any more power than last time and still makes less power than the 2560 did.

The car's owner is going to go back through the motor and look for anything that can explain it.

He didn't change anything other upgrading from a 2560?

LOL @ upgrading to 4" exhaust without first measuring backpressures.
