Dyno Results
Hello,
I am getting ready to do a cam swap next month so I brought my car in for a baseline dyno session to see where it was at before the mods. So, I thought I would share my experience for others looking at similar upgrades.
The car right now...
- 2002 Z06 with 28,000 miles
- Halltech Venom Intake
- LG Street Headers with no cats
- Stock TI catback exhaust
- Stock Z06 rims
- Nitto Extreme RII Drag Radials
- New AC Delco Irridium Spark Plugs
- New GMPP Plug Wires
- All fresh fluids
- Self tuned MAF only
- AFR set to 12.6, timing at WOT is 24 degrees
The dyno...
- MustangDyno
- Temperature was 88 degrees
- Humidity was 80%
- Weight was set at 3300lbs
Dyno Results...
- Pull one - 389.9rwhp, 355rwtq
- Pull two - 383.9rwhp, 351rwtq
- Pull three - 385.4rwhp, 353rwtq
I was surpirsed that the car put down such good numbers on a tough Dyno with basic bolt ons. I wish I would have Dynoed before the mods to see the increase along the way. The shop says that most bolt on C5Z06s they dyno put down around 360-370rwhp. Looks like my motor is breaking in well. i hope I don't regret tearing into it.
The Plan....
Next month I will be installing phase one of the AFR heads/cam combo.
- AFR 224/228 cam, .581/.588 on 114 LSA
- ASP 25% underdrive pulley
- Patriot Gold Dual valvespring kit
- Comp Hardened Pushrods
- New belts, gaskets, ARP bolt
- Full Dyno and Street Tune
The target goal is 8-10rwhp from the underdrive pulley and 30-40rwhp from the mild cam. If all goes well we are talking stock C6 ZO6 performance numbers for about $2500 in parts. Pretty impressive from a 346cu motor.
I plan to add a pair of AFR heads and ported FAST intake down the road.

Great work for a set of headers and intake. With your ability to monitor the A/F and spark, you should gain a lot of hp when you add a cam and headers.
IMHO, most people don't know that adding an airbox causes the PCM to generally report LESS not more air, even at idle.
Any track times to cross check yet?

Moroso in West Palm Beach, FL is supposed to open up again next month so I may have a chance to run it then. However, my driving skill would be poor...
