Stock 2008 C6Z goes on the dynojet today (baseline) Well a friend wanted to dyno his car and I've been itching to stick my car on the dyno aswell. So I let the car cool to see what the car dyno's when the starting coolant temperature is at 170* and at 195* operating temp.
So I did learn a few things about the cars performance I think.
Dynojet 224-same dyno as my C5 was dynoed in my sig.
DYNO SAE
439rwhp/422rwtq-170* coolant temp
445rwhp/425rwtq-195* coolant temp back to back pull
Then cool down try again.
444.00rwhp/425rwtq-170*
447rwhp/428rwtq-196*
Typically these cars always pull higher #'s on the dynos. This perplex's me that the cars performance at the track shows the opposite. I run the car down the track at 195* temps and the car will trap 123-124mph. If the car is at 170* the car runs 126-127mph.
On the dyno after I figure how to post the graph. The cars torque is lower on the colder engine temp by approx. 12rwtq from 2800-3700RPM then matches up for the rest of the run.
Uncorrected #'s which air temp was approx 50* but cloudy overcast day.
463rwhp/443rwtq-170* coolant temp
465rwhp/445rwtq- 196* coolant temp
I dont want to go into a long story on this one but as many know I ran 11.09 at 126mph with a 1.76 60ft in +40 DA at Cecil Dragway.
Well I took the car to MIR and I'm pretty darn sure the weather was alot better and the car didnt come to run to my expectations.
11.24 at 125mph with a 1.76 60ft definitely a negative DA and a headwind of approx 15mph. I lit the clutch up on the first run regretfully and not sure if she's gonna recover easily this time. It actually smelled on the dyno but comparing RPM to MPH doesnt look like it effected the dyno runs. IMO the car definitely has the power/torque to get me in that 10.9x range that it should be but i'm not sure if the clutch is going to let me.

So lets get this straight you bought a car with more WHP and weights less and spent and extra 20K and the car is slower...
