well I decided to see what the "worst case scenario" for my car would be. I didn't take any weight out of the car except the A/C and AIR delete I did 2 months ago. spare tire and jack remained in the back. I rode on my heavy TT2s and sumitomo rubber.
I went to island dragway in NJ. I dont know what the DA is. the track is 600 ft above sea level and it was in the high 70s. humidity was probably up there since it rained alot yesterday. ok enough excuses...

I ran a total of 8 times. all of them except one botched run and my best run were in the 12.8-12.9 range @ 112 mph.

heres my 3 best:
60'---2.088
330'--5.546
1/8---8.332
MPH--88.55
1000-10.720
1/4---12.727
MPH--112.53

60'---2.126
330'--5.632
1/8---8.423
MPH--88.40
1000-10.812
1/4---12.820
MPH--112.57

60'---2.090
330'--5.644
1/8---8.451
MPH--88.00
1000-10.850
1/4---12.864
MPH--112.15

I made the first pass of the day right after they sprayed down VHT. I cut a 1.995 60' on STREET tires! thats a personal best lol. after that I couldn't hook at all. I had to give it such little throttle that it shifted into 2nd before I hit the 60' mark. after it shifted into 2nd I just rode it out. one run it shifted back into 1st once I went WOT, spun ALOT, and I ended up running a 13.5 @ 110.5.

My best pass last year was:
60'....2.015
330...5.398
1/8...8.198
mph..87.54
1000.10.630
1/4...12.685
mph..109.72

the only difference between last year and this year (besides the much cooler weather for last year) are:
sumitomo street tires in place of BFG DRs, pacesetter LTs/Y-pipe in place of mac midlengths, no cat this year, hooker catback in place of SLP loudmouth, A/C & AIR delete this year, and ran with no spare/jack last year.

I don't know what else to do to add power or free up power. All the little stuff seems to be ok. my brakes aren't dragging. my plugs/wires all seem good. no trouble codes. I figured I should be trapping about 115. I set out to get 11s with this engine. My ideas are:
dyno tune, drop rear section of catback (straight pipe exiting after rear axle), remove sway bar, remove rear seats/spare/jack, put old 16x8 stock wheels back on with 255/50/R16 MT ET streets mounted on the rears.

I don't know if I can drop 8/10ths of a second with all that. thats alot of time to drop.

whats odd is just about everyone at the track runs slow too. there was an 03/04 cobra with at least pulley, CAI, exhaust, and DRs running high 12s @ 114. There was a supercharged 05-06 saleen mustang GT running 12.x @ 110. some supercharged 99+ mustang GT running low 13s trapping 107. I would say its due to the drive but everyone seems to run slow there.

It leads me to believe the track is slow. Afterwards I raced a bolt on 344 rwhp 99 T/A WS6 M6 and beat him by 4-5 cars from 40-130. Even on the 150 shot when he puts down 480+ rwhp he only took my by 4-5 cars up to 130. Im pretty even with a 360 whp SRT-4 neon with an AGP .50 trim turbo kit with all that weight in my car. I probably have a 500-600 lb disadvantage to that car. So it seems im making close to 400 rwhp.

Oh well, I'll just keep on at it! if anyone remembers when I first ran my 383 at the track I ran a 13.7 @ 103! If I keep fixing stuff sooner or later I'll get to where I want to be.

Hey bro, one thing I havent heard you talk about was any suspension mods. They are often over looked. You can make a stock motor car run a substantially lower 1/4 mile time and 60ft by upgrading your suspension.

Torque arm, subframes, lcas, ect will help you dramatically while reducing weight on most parts.

Take some weight out and get some draglites with a better tire, I love the MT DR's, and Hoosier QTP's, also some skinnies for the front. Get that 60ft down and you will start shedding away the ET for sure. Pulling the front sway bar out will also help with weight transfer and 60ft a good bit. No matter how you look at it your taking steps in the right direction.

Do you have suspension mods? Basic bolt on suspension stuff, lcas, sfcs, adj TA, etc, even with stock springs and shocks, and a set of those 255 M/T radials on the 16x8s and you could shave 5 tenths off your 60', which could bring you real close to your 11 second run. I run a very basic suspension set up which is not optimised for drag racing (still have both sway bars in place) and I 60' in the 1.55s. I found that working with the pinion angle is huge and often overlooked... How are you launching with that TCI converter? I have heard some not so good stuff about their converters in our cars. Do you bring up the rpms or flash it from an idle? At the very least get a set of the 255 50 R16 M/T radials and have at it...Good luck...

Yeah, you definitely need to get that 60ft. in the 1.60's at least! If not better.
