I made 480/412 on 9 or so psi... with a super safe a/f except above 6200 rpm... the damn 255lph pump is maxed out... so it gets real lean up there. I am super happy and am gonna upgrade to the 03 setup (fuel pumps) and tune it down a bit.. maybe something like 450/400 would be good until i have more money for a shortblock.
dyno results are in!!!

WOW! Awesome numbers for 9 PSI! What kind of S/C? I'm assuming you have a stock bottom end since you said that you were saving money for a shortblock.
What kind of injectors? Intercooled?

Where you the guy that was going to run a smaller underdrive pulley to keep the boost low on the S-trim?
I'm running the s-trim and I see 13 lbs of boost.
If you are going lean over 6200RPM's, DON'T chance it. Shift by 6,000 until you upgrade the fuel system. Did you think about adding a boost-a-pump to your fuel system to help out on the high RPM side?
Nice numbers!:beer:

nah, not me. I got the s-trim, but with cobra impeller... i am shifting by 6k so no biggie. thought about it, but still not sure. running like 14-16 deg of timing or so... but still fat a/f curve. any other ideas for fuel?? besides 03 and BAP. think my block will hold at 460-480rwhp ?? tune is real good.
OK, so you have the SC-trim. What is your a/f at? If I remember correctly, my a/f is at 11.8, then around 5500RPM it goes rich and goes to around 10.8 . My timing is set at 14 degrees. I'm running 94 octane. Plugs are gapped at .028 .
I hear the pump you are running can be a problem due to the returnless style setup, but don't quote me on that.
What injectors are you running? I'm running the 03 Cobra injectors and MAF. I was going lean over 6,000RPM as well, but after we put the BAP on it cured all my problems. Not very expensive either.
Oh, and at 480RWHP, as long as you run high octane gas, don't get detonation, and change out your plugs.....assuming nothing goes wrong....you should be fine. But be prepared for the worst....cause you just never know.

Are these the same or different? I thought for the 99-01's you could only get the SQ from Vortech. :shrug:
SQ is the way the gear is cut...makes it "super quiet"
S-trim has the GT impellar....more boost, biulds boost down lower too.
SC-trim....made for the Cobra's to keep boost lower. 9-10 lbs is the norm.
E-trim...what they originally recommended for the 99-01 Cobra's...only 6 lbs of boost.
V2 (SQ) is what you see most of the time on our cars. They still make the V1 which is the loud one.
Got it.;-) :beer:

go get some new track #'s mike and u better be in the low 12's if not 11's or i am gonna come down there...lol:burnout:
you are correct....helical cut vs. straight cut gears....
after you get a new fuel pump...i saw in a post a guys was trade/selling some parts ...didnt know if u saw it...its in this forum
Are the S-Trim the same price as the V2 SQ?
You missed what I posted...I have the S trim, model V2 SQ.
S= impellar blade.
SQ=the cut on the impeller blade.
V2=not sure here, but I beleive this is what every SQ model is...like "version 2"
Your options are for your motor:
E-trim
SC-trim
S-trim
Then you can go bigger in the trim levels but you better have a motor to go with it.....:beer:
