fp green dyno today.
May want to trade out those Revolvers for a set of some Cosworths. I have yet to be tuned, but i must say the mid to top end with the 20glt now is ridiculous. Wish i actually was tuned and dynoed to see the real results tho.
i agree, ct9a gsr made 389hp and 420trq on topspeeds dyno w/ less mods... there is power missing somewhere, i'm gonna check my cam gear settings, see if there's power to be had there. I just can't think where else it could be.... i was hoping to be in the 450 range. had too much pump gas in for c-16 tuning.
GSC S1 cams are producing good numbers for people. Wonder if your meth pump stopped working? I know of a few people that had problems with their SMC kit not working up top. Once you find the problem I'm sure you will close to 450whp.
Then I guess you missed my point. 
That extra boost whether it holds it or not has MUCH to do with peak power. Do you see any stock turbo running 22psi making 400whp? NO. You hardly see 370whp ones, however with high boost you will see that and thats with it dropping hard all the way down to 21psi from 28+.

IN the end, both would theoretically have the same peak power output, one would have a huge torque spike, one would be pretty flat
i'm pretty sure if my meth stopped working knock woulda been going crazy @ 28psi, but doug did suggest a larger nozzel for better flow = higher boost on pump. But even @ 28psi, i should be making more than 400
are you serious? If properly tuned you can set your peak boost at 22psi and hold it all the way to redline

I see what youre saying and you are correct IF the situation I just spoke of did exist (hitting 28psi or so then immediately going to 22psi), however this is not what happens.

^^^ Agreed. Spiking 28 --->22 owns spiking only 22 --->22 by buslengths on the street.
Who cares if horsepower @ 7000rpms is the same; the area under the curves of the two cars would be miles apart.
The car spiking 28psi would be looking back at your headlights in the rearview before either of you even got to 7k...

I would be as well.
For starters, your fuel injectors are almost double what you need if your methanol injection is sufficiently sized (unless you plan on using E85).
Where the methanol injection is concerned, if you're using anything smaller than an M10 nozzle, it's too small. An M15 would be best.
If you don't see a quick burst of flames coming from the tailpipe when you lift the throttle immediately after a WOT run, your methanol injection isn't working.
You mentioned cam gears but no settings.

Ya Im real serious. You must be confused. This "tapering" that happens to the boost is very gradual. Its not hitting 28psi and slamming in a quarter of a second back down to 22psi. It slowly tapers but makes more boost just about everywhere until aruond 6800-7000rpm. The car running higher boost will make more torque and more power across the rev range. This is evident in EVERY stock turbo running meth or race gas, or hell, even my car. My car spiked 25psi and tapered to 19psi. There are a bunch of guys holding more to redline on the stocker on pump and not coming near my trap. This whole "taper" stuff is non-sense and not a big deal

Seems like pretty good numbers to me. I'll keep an eye out for when you do cams. I'm doing the cams first, along with fmic, piping, tbe, avc-r, et.al. before i go to the fpgreen, which is my next step.
