Default Finally got into the 11's, I want to join the club!

After three years of waiting, I've finally made it into the 11's! I never got there with my Turbo 3.8L Firebird(12.10@114mph), LQ4 powered Firebird(12.08@114mph), I ran a new best today with my 98 Formula.

My mph seems kind of low, the DA today was 1550ish. I like my 1/8th mile time and speed, just thinking maybe I'm shifting early. The car has the following mods;

stock LS1 short block
PRC stg 2.5 5.3L heads w/ 59cc chambers (11:1 static compression w/ GM MLS Head Gaskets)
eps 226/234 cam (.598"int/.601"exh 113+2 lsa)
Stock 1.7:1 rockers
comp 7.4" pushrods
LS7 Lifters
Katech Rod Bolts
LS2 timing chain
LS6 oil pump
Fast 92/92
slp lid
Ford #30 injectors (36@ 58psi)
pacesetter lt's w/ ory and magnaflow 3" catback
homebuilt 4L60E
4000 stall converter
stock aluminum driveshaft
3.23 rear gear
26" 275/55/15 MT ET street drag radial (22psi hot)
15" weld prostars
SD tune

Here's a couple passes down the 1/4 with HP tuners log files, maybe someone can decipher that jibberish??

Congrats! Are you shifting your A4 manually? After a lot of reading and trying, I found it's best to just put it in 3rd and let the computer shift... Give it a try next time out, my car liked it.. Agreed, MPH seems low.. But hey, welcome to the 11's!!

Not trying to be a dick but the mph and ETs seem off. My cam only full weight car runs that in worse DA. 1/8 looks a little slower then it should, and 1/4 is definitely off. Compare our slips if you like:

I know it seems off to me as well. I'm only running 26 degrees of timing, the pcm is set to shift at 6100rpm. It does the 1-2 shift around 6100, and 2-3 at 6500ish according to my hp tuner logs. I'm also close to full weight and with a 6 point mild steel cage. Only things this car doesn't have is ABS, EGR, AIR, Cruise Control, carpet insulation, spare tire, and the backseat. I'm 150lbs on a good day as well.

What is that D/A? Your definetly running slow and your mph is down. With that 60ft you should be running low-mid 11's easy @ 116 or higher

The DA for that pass was approximately 1550. I'm thinking my shift points need adjusted, I'm going to adjust them some and see what I can come up with. I need to wait until my local dragstrip begins Saturday test and tune(when their drag season ends)

Shift points should help. I see you are running at Kil-Kare, they have TNT every thursday evening. I will be there this week.

I would be there, except that I have class Thursday nights at Wright State. I may roll down to Tri-state for a Saturday t&t

You are on the right track, 60' is decent just need to up the shifts. I'd say 6600 minimum for both shifts will give you another 1-1.5 mph.

I'll be sure to get those tires back you before thursday.
