Default max Greddy power

Any guesses what kind of power I'll make with the 550's, Link, big FMIC, 96 Torsen, RM DP, and full 2.5in exhaust with no cat?

With 550cc injectors, you'll likely be able to push the TDO4H-15G to its limits: around 275rwhp.

I say 275whp. Not sure if the turbine is going to push 300whp.

Well, you'll always see power gains going with a bigger exhaust to increase the pressure differential across the turbine. I would imagine the gains would be pretty substantial at the 275-300rwhp when moving from a 2.5 to 3.0" size, but not necessarily if the turbo is already about maxxed out.

Tough call...but if you're really shooting to max it out, you'll probably want to go bigger than 2.5".

Probably start with the 2.5 in place and then see where that leaves me.

Oh, pulled the cat too. We're also talking about a 2.8l motor with a t3/to4e.
