How much power/spool with..
While my megasquirt remains unresponsive i was wondering what kind of power im going to be getting with my turbo set up.
*Greddy TD04-15c turbo (Different compressor wheel than 15g)
Greddy cast manifold
Custom 2 1/2" downpipe swages to 3" all the way back
Magnaflow 3" high flow cat
Summit racing 3" turbo muffler
trust FMIC (like saab)
rx7 460cc injectors
MAF delete
Turbo blankey
2 1/4" intercooler piping
Still to be added is devils own WI
Anyone have a guess on what kind of power/spool rpms id be makin with and without WI
Thanks ya

15c probably flows more at a slower speed and becomes inefficent sooner than the g. Or its the other way around. In the first case, you would get boost a tad sooner and make a tad less power than greddy guys. Probably wont be all that noticable. You are thinking about this way too much. Water injection might improve spool a tad and increase efficiency

If my quick mental math is correct, you'll run out of fuel at by 250whp at 80% duty cycle on stock fuel pressure. An upgrade to 550's should let you realize the limits of the turbo, but I think you're pretty much there. A 2% trim advantage isn't going to be noticeable over a regular 15G and they run out of grunt in the 16psi/250whp range.
Spool will be about 500rpm behind a comparable GT2560 which is the closest I can imagine this to be to a Garrett model. The Greddy manifold is the limiting factor to spool in your setup, so a good guess might be starting to spool at around 3000rpm (or a pinch later), with full spool by 4500rpm. You'll probably run out of grunt in the 15psi range.
A little water injection never hurt anybody, but my reading indicates 18psi is the absolute upper limit based on turbine RPM reaching ludicrous speed.

Oops forgot to add i have a walboro( did i spell that right?) 190 fuel pump if i get above 200 ill be happy and thanks koto for not flaming my nubness
Edit: do they make manifolds to upgrade the greddy?

You're right Koto, I'll go another 15whp as he's got access to 92octane... but it's still basically a Greddy turbo/mani on a 1.6. The bigger exhaust will help a bunch. In the end, it'll come down to how much timing he wants to run.
235whp@15psi seems doable with a fully tunable ECU on that turbo/mani combo.
