New mods, new times
Last week I ran 13.88 @ 99.6 mph with my 1995 Z28 A4. Since then, I hollowed out the cat, removed the muffler, 160 deg thermostat, Hypertec power program, homemade 3" pvc cold air intake, and LT4 Knock module. The car went 13.40 @ 102, almost 5 tenths better!
With a 50 dry shot, hit right after hitting the gas to hook, it went 12.56 @ 105.6. I was shocked at that! The 60 foot time was 1.76 (stock converter) BFG drag radials and it went 7.99 in the 8th @ 86 mph.
Just thought I would let you guys know what you can expect doing these things.

Thanks,
I forgot to mention that my car has 101,000 miles on it. I have also done the tb bypass, aluminum driveshaft, 1.6 roller rockers, 612 valve springs, descreened maf, underdrive pulley, Moser 9" with 3.89 gear and tpis airfoil.

When I first got my car last year, I ran it with nothing else but an oil change, BFG drag radials, and trans fluid change and it went 14.93 @ 93 mph. The car was a total dog...turbo bugs were beating me! It was a little bit hard to start so I checked the fuel pressure and it was 33 lbs. The stock fuel pump was on its way out. I put the Walbro pump in and WOW! What a difference! The following week, it went 14.40 @ 95.5 - that was just the fuel pump.
The next time I went out, I installed new plugs, air filter, tpis airfoil, tb bypass, and underdrive pulley. The best I could get out of it was a 14.32 @ 96.8 mph. It was pretty hot that day, and very humid so it probably could have done better. I was all set to lay at least a 14.20 or so with all of those things. I drove home a bit disappointed.
The following week, I installed a Moser 9" locker with 3.89 gear (originally a 3.23 with posi going out). It went 14.10 @ 97.3 mph. It was a cool night so I pretty much got what the car was capable of. I was pretty happy - especially with the mph gain. The 9" is notorious for eating up power so I wasn't expecting that.
A few weeks later, I installed 1.6 roller rockers, guideplates, 612 springs, retainers, keepers, and hardened pushrods. It was hot out that night but it went 13.91 @ 99.3 mph. The car was clearly running better and a few weeks later, it went 13.88 at 97.6.
That was the best I had done until last night with those mods -hogged out cat, 160 thermo, Hypertec program, LT4 knock module, muffler removed, and extreme cold air intake 3". Those mods put me at the current 13.40 @ 102 off the bottle, 12.56 with a 50 dry shot.
Little things really add up with these cars! Now I need a converter and headers.

Damnit i really want the 24th to roll around so i can take mine to the track and spray the 150 shot.
But i dont think im going to have time to install my new fuel pump before our dyno/track day on the 24th. So i guess im going to see what this 204K mile fuel pump has left in it
As rich as the car runs at WOT im assuming it works pretty good

I was shocked at that too. The jet I used was .042 which I think is about a 50 shot. I was a new bottle with 1000 lbs of pressure in it.
This is the same Compucar system I used on my 1996 Neon with underdrive pulley and Dynomax super turbo muffler that went 14.86 @ 93 with the 50 shot. It went 16.83 without the bottle so that was 2 seconds off the quarter time.
I had a 1970 Buick LeSabre 4 door that I put a 150 fogger kit on back in 1987. The car had 295 hp from the factory I think I remember, and although it weighed over 2 tons, it ran 15.70 off the bottle, and 13.60 @ 101 on the bottle. You talk about a sleeper! It was also my pizza delivery car when I went to Ohio State - I couldn't believe I was getting paid to race people all night with that thing!
