NASA...we have lift off!
Fellows,
I've just come back from shop (Paddock Performance) and we've corrected an existing A/F problem...and did a few other things.
Mustang dyno runs done at 18.5 lbs of boost now produce 424 HP at 5,667 RPM and 391 lbs/ft of Torque!
When the boost is turned down to a more modest 15.5 lbs, the resultant numbers drop to 371 HP and 336 lbs/ft of Torque...Plenty of oomph
for me; while maintaining a bullet-proof monk!
All the while maintaining an A/F of around 12.1 to 12.4.
So, what would those numbers be if they were translated to flywheel HP and TQ figures?

General rule of thumb is 15% driveline, so its would be safe to say you are making some serious power . I do notice that your torque numbers dropped. Also, what boost levels do you plan to run at?

I think I'll keep the boost at the more conservative number of 15.5 lbs...Seems like it's still plenty of power to play with.
Yeah, the TQ numbers at 15.5 lbs of boost are lower than before...not sure what's up with that either.
Car was re-tuned and is running on 93 octane pump gas now, too...that'll save me some money compared to race fuel!

Jason,
I'd guesstimate 470 hp and 412 hp, respectively, at the crank. Wow!
BTW, you need padding on your rollcage. I'll try to email you tomorrow. It's getting late.
Ciao!

Jason,
Stopped by Paddock to drop off a part for my car this afternoon. Your car was on the dyno (a new O2 sensor was plugged in) and I witnessed the last two runs: 386.6 hp & 415 ft lbs. torque. Last run: 386.9 hp & 405 ft lbs. Boost was at 16lbs.
That's about 430 hp at the crank, I guess.
P.S.: A/F was at or just under 12 for all runs.

Richard,
Thanks for the update!
By the way, if I can 275's under the front, I just may go with the Hoosiers this year...I do worry about the potential rub up front, though. If the 275's work, then I'll try the 275/35/18 and 295/30/18 combo.

Jason,
I don't believe you'll have a fitment problem with 275's, but if you're truly concerned, Hoosier sells a 255/40 18 in the R compound which would fit 8.5 - 9.5 wheel width. Why not try my 10" rear wheels (that have 285's on them) on the front of your car? If the 285's fit, then I guess the 275's won't be a problem.
SBump,
Well, when you think about it, a part for my car is part of my car. No?
