Hi all,
Went to Island last night. I got 7 runs in! It was great.
Short version:
Ran an 11.83 @ 115.0.
Long version:
Got there and saw there were 2 other GNs there. One was a board member with whom I've exchanged lots of e-mail but had never met in person. It's great to see people in real life. His car was running really great though neither of us could hook up on our new Hoosier QTPs (more on that in a minute). The other GN guy didn't really come over to talk to us.
I put 5 gallons of 116 fuel in it along with the 8-9 gallons of 100 octane I already had. I figured I wouldn't have to worry about knock and I can focus on other things. I was right.
First run I just rolled up in "street" trim. Didn't mess with the air in the tires or make any adjustments. I ran 12.0 @ 111.
So right off the bat I was slower than my best MPH last year but close to the ET. New mods this year are PT-61, 9x11 converter @ 3400 stall, 60# injectors and a PTE doghouse.
Second run I took some air out of the QTPs. Put both at around 15 psi. I was rewarded with a crappier 60' time and ran a 12.2 @ 111.
Third run I figured I'd change chips. I took the TT chip out and replaced it with my Extender. I spun even worse (2.0 60' time) and ran a 12.8 @ 108. In all fairness the Extender chip is an "alky" chip and the TT chip is a 100 octane chip. The TT also locks the converter at 90 MPH. So I put the TT chip back in.
Fourth run I figured I'd just concentrate on launching it. Made no other changes. Got a 1.9 60' time and a 12.2 @ 111. Hmmmm. The QTPs were beginning to piss me off.
Fifth run I put MORE air in the QTPs. 60' was 2.3, ET 12.9 @ 112. This time I actually looked over at the boost gauge. 22 PSI. DOH! Need more boost.
Sixth run I turned the boost up to 25 PSI. Took some air out of the Hoosiers which got me a 1.807 60'. Got a 11.89 @ 114.95. That's better - a new personal best.
I lined up one more time without changing anything. Figured I'd get the QTPs REALLY hot this time. Got a 1.817 60' and ran an 11.83 @ 115.0, besting my previous best from minutes earlier.
The last run was vs. a new SRT-10 Ram pickup. 500 HP. He had been running high-15s @ 95-97 MPH all night. As soon as I launched he threw in the towel. He ran a 20.9 @ 72 MPH.
All in all, my 1/8 mile times have not changed with the new parts. The improvements are after the 1/8th. It's pulling harder on the "big end" as they say, but I'm not sure if it's just because the converter is locking or not. The car should be faster, but I'm not running an aggressive chip yet. O2s are good and it's not knocking. I'm going to get a "real" race chip or two and see what happens. Also I'm at around 5300 RPM at the end - not sure if I need to move to a 28" tire or not.
