[s-cars] Second trip to the drags

Dave,
 Wow, nice numbers. I bet you'll be in the high 11's before you know it. When you say you tuned the 928 maf, does this mean just adjusting the allen screw on the MAf it self? I'm still a ways off from having mine in but hope to gain as much info through you and others before I install it. As for the clutch, the fiber carbon six puck clutch I got from clutchnet is very nice and makes the centerforce feel like a stock clutch the way it grabs. I can get more info on which one I have if you decide to go this route.

Subject: [s-cars] Second trip to the drags

After spending some tuning time with the 928 MAF, I got the chance to take  
the car back to the dragstrip again today (Boise, ID)

Again, the strip is at 2700 ft.  Tuning the MAF resulted in being able  to 
eliminate the hunting that had occurred last time out, and the car was  pulling 
well.

I did 3 runs before the Centerforce cried for mercy.  On the third  run, it 
was slipping hopelessly in 2nd gear, and I decided to call it quits  before I 
had to tow it home.

Worst run... 12.713 @ 112.65.  Best run... 12.400 @ 113.35.

My 60ft times are getting worse as the clutch goes south.  My best 60'  time 
today was a 1.997... almost 2 tenths off the pace from my last visit.

With the right clutch... I think this thing could be bangin' on 11's  door.  
Problem is, where does one get a better clutch for these cars?

As a side note... I ran my G-Tech Pro RR simultaneously on each run.   The 
worst variance between my timeslip and my G-Tech: 6/100s of a second.   Now 
that's what I call impressive for a $300 tool.

For those thinking that trap speeds are better for calculating hp than a  
dyno... 113.35mph and 4000lbs come out to 455atw... interesting.  Guess  that 
SAE 
correction factor isn't too far off after all.

Take care,
Dave
