My current car is a 1989 Iroc-Z. It came with the 5.7 liter V-8 (L98), 700R4 transmission, and Borg Warner rear-end that originally had 2.77 gears. The suspension was altered before the other modifications with only Eibach springs and KYB shocks. Below is a list of the performance results over the past 5 years after several bolt-ons were added along with recent 350 Dyno results. My motor went south around July of this year (fried the bearings) and has since been replaced with a brand new 383 stroker along with a few other hi-po parts. After the engine swap I was able to get 383 Dyno results.Click on the links for some specifics.
The rims I'm using are: Centerline Saber style 394. They are 17x8 up front and 18x9.5 in the rear. The tires that I'm using are Nitto 555 Extreme ZRs. 255/40 ZR-17 94W(front) and 275/35 ZR-18 (Rear). You can also spot my new fog lights from Catz by FET. They are much brighter than the factory ones and they allow more air to go by in to my intake.

Performance Results:

Please realize that as the car became faster I also became a better driver. As you can tell, my first few runs had significant wheelspin off the line which I have now corrected. The 60 ft. times (not listed) have dropped significantly with no additional changes to the suspension. Click on each modification to see my 1/4 mile times and trap speeds after it was added. The runs were done at different times of the year so the weather and track conditions weren't consistent. Your results may vary.

  1. Stock with Dynomax muffler
  2. With Saga Ram Air Intake and 170 degree fan switch
  3. With Hypertech Chip and MSD Wires
  4. With Flowmaster cat-back 3" exhaust and Split Fire plugs
  5. With Edelbrock TES Headers
  6. With March 3-Piece Pulley Set
  7. With 3.45 Gears
  8. With Crane Cams AFPR & ported plenum
  9. With MSD 6AL & Blaster II Coil
  10. AFR heads, ZZ9 cam, SuperRam manifold & Crane Gold 1.6RRs
  11. New Motor: 383
  12. Super Ram plenum/runners & 24# injectors
  13. BFG Drag Radials

*These runs were done over the course of the last 8 years. All runs were done with 275/35-18 tires with 35psi (unless noted otherwise) which is exactly how I run them on the street.
