I finished getting baseline numbers for my 1994 Z28 tonight as I took it to the track. As stated before, I'm starting this build from scratch and keeping track as I go. The car is a 1994 Z28, A4, with 2.73 gears that is stock with the exception of ZR1 wheels and Eibach lowering springs. Rated 275hp and 325tq it dynoed 230 hp and 273 tq to the ground. I had previously g-teched it just for comparison's sake. It ran a 14.1 @ 100ish on the g-tech.

Tonight I got the final baseline for it at Lebanon Valley Dragway. I left the car untouched except for changing the oil (conventional oil) and setting the tire pressure to 45 psi front and 35 psi rear (changed to 30 psi after the second pass).

My first run I spun to a 14.79 @ 96 mph with a 2.40 60'.

Second pass was not much better with a 14.63 @ 96.5 mph with a 2.25 60'.

At this point I was beginning to think that maybe I just got a slug. I was pleasantly suprised with my final 2 passes.

14.33 @ 98.0 mph with a 2.20 60'
14.32 @ 97.5 mph with a 2.14 60'

Nothing earth shattering, but at least the car is running what it should for what it is. I would not have been happy going home with a 14.6, lol.

Now I can move on to the next stage. I'll be getting and installing a Magnaflow cat-back, K&N CAI, airfoil (the Thunder Racing Kit), a 1LE elbow, Nitto drag radials, and Royal Purple oil. Then it will be back to the track and hopefully a 13.9 second pass unless the weather kills my performance.

I'll be holding off on the dyno until I get more hp mods than those listed above. At $100 a pop for 3 pulls on the dyno, the track is just more fun.

 

I'm glad you got the results you expected.

I've been doing the same thing. I plan to go a couple more weeks before I pull the engine out of mine to do the following.....

• Headers
• High flow cats
• CC503
• CC Pro Mag 1.6 rockers (NSA)
• New timing chain
• 37# injectors

I forgot how fun the track can be....been a couple of years since I've been. The one's around here are 1/8 mile. The best I could muster that night was a 8.9@81(should get better once I learn the track). I've never been to Farmington before....nice little track.....however the left lane would not hook worth a dang....right lane would hook hard.

 

Your stock injectors will work for you...easily at the power levels you will be at.

 

Agreed, it would be a waste of money to replace the injectors unless they are broke.
$100 for three dyno pulls is too much. All places around here are $75.00

 

^Yeah, $100 is actually the cheapest place around here. There was a great place that charged $75 the first time, $60 the second, and $50 every time after that, but he went out of business.

ACE1252, I'd listen to these guys on the injectors. I've never been to an 1/8 mile track, but any racing is better than no racing! Those new mods should really make a difference! Keep us posted!
