Just thought I'd post up some info from my first day out with the new combo. Unfotunately I only got in 7 runs, I arrived at the track late, only had about 3.5 hrs to get some tuning in. A few guys have asked about my combo recently, here goes.
S2 oncenter 4.1, with Champion R heads from the latest version, about 2 years old and a "bunch" of passes on them. Heads and motor were freshened up recently after 2 years of, yes, you guessed it, a "bunch" of passes. So we replaced my 4 plus year old hyd. roller cam with a new solid roller cam recommended to me by my engine builder, (RPE in Hartford, Ct.) Yaaaaaa, he's the man!!!! 274" motor, think around 8.75 to 1 comp., BMS crank, BGC intake, ATR headers, modified by me for my brandy new Turbonetics T88 turbo, built by Kathy from T, Yaaaaa, you guessed it, she's the best!!! 3.5 DP, 160lb inj., 3.5 exhaust system and last, but no least, of course, my very own Cotton's performance frt. mnt. IC, the biggest and badest IC available.
Fired her up a few nites ago, everything was pretty normal, couple minor "opps" but overall, 150lbs oil pressure, yep, I know...... we adjusted it, wanted to make sure it was alllll there. Tuned in the base idle, made a couple of spoolups, to be sure, everything looked good. Washed her up, looks great, all one color again, loaded the Pumpkin in the trailer and left for the track. We arrive, go thru the usual warmup the rear end on the "jack", check everything over one more time and head to the staging lanes. I'm my usual calm, cool and terrified, all at the same time, self
Remember now, this is a track rental by a bunch of kids, with everything from F-bodies to BMW's, not too many slick cars so traction was not good. I spool up at the line, all good at this point, let it fly at a conservative 8lb launch, 17lbs down the track, go 20 ft, unload the rt tire and take a sharp right turn. OUCH, no problem, I lift and jerk it back to the left, coast down the track, I gave it a little pop half way down, seems ok. NowI go back check over the air pressures, head back out, same thing, only go about 40 ft before taking the rt turn, back to the pits after once again, giving a little blast half way dwn. Check the springs, shocks, control arms, everythng looks fine, never did this before. ok, number 3 pass, this time, 60ft, tire unloads, rt turn, lift bring it back after gathering my wits, hit it at about the 330 and run 130mph, 12.23. hmmmmmmmmmm, WTF !!!! heading back down the return road, my son stops me, says they saw water come out of the frt rt blinker assembly when I launched......... naaaaa, no way, he says, Yaaaa waaaaayyy. Ok, getback to the pits, sure enough, the lense is full of water!!! I only had one of the lite bulbs pugged in, when he washed the car the nite before, must have filled up the lense, the quarter sized hole allowed enough water to splash out on launch to break the rt tire lose, hence, rt turn!!!!! 
Talk about weird!!!!! empty it out, back to the line, 8lbs launch, 17lbs of boost, 6200 rpm, 9.70@139.... something. Next pass, 10-12lb launch, 20lbs boost, 9.50@145 plus, oh ya, no hook either pass. high 1.40's. Next pass 12lb launch, 7,000rpm in 1st, rev limiter kicked in, forgot to raise it..... 6400 in 3rd, more spin down the track, 9.56@144.99. Hmmmm. ok, one more time, 15lb launch, 21-22 lbs down the track, spin em hard off the line, 1.56 60ft, it takes Fn\off, 7600 in 1st, 7300 in 2nd the 1\8th mile is comin up and I see something in the middle of my lane, WTF... can't drive around it, so I lift coast over it, the runs over!!!! Damn mustang threw a blower belt, about 6 cars before me, the punks in their imports must have drove around it before me, and never said a word to the track officials!! Felt like a good one, get my slip and I run almost 119mph in the 1\8th!! Previous runs were 115 in the 1\8th, 145 in the 1\4. If ya do the math, it should have been somewhere round 149mph!!! On only 21-22lbs of boost,just saw a couple blips of 23lbs in 3rd gear for a moment. To sum it up, the Pumpkin is back and ready to run, not sure how much boost I'll be running, would like to keep it around 24-26, maybe take a peek at around 30, but I think my goal of running low 9's should be easy at a safe boost level with maybe a blast here or there if I'm close to the magic number, don't want to say it though. With some decent hook today, I should have been able to run 9.20-30's.
I have to thank Bobby, Paul, the best bodyman, Kathy and my boys for getting me back out again. Sure feels good.....
