There's something worng their. Typical rwd vehicles lose around 15% power threw the drivetrain. This mean the C should have in the range of 306RWHP. Either these numbers are something they pulled from their arses or the C's do not have 340hp.
As someone that owned and operated a Dynojet for a while, I can say that an automatic RWD car should lose somewhere around 20-23% in HP through the driveline. Torque loss should be about that much also.
So the torque numbers do seem way low, and the HP numbers are a little low.
I would recommend turning off the stability program, and also was this a very low mile new car? If so, you can expect numbers to come on noticably after about 10,000 miles.
Another thing, are the numbers corrected? The Dynojet can give "actual" numbers as of the test, or it can give corrected numbers, factoring in altitude, humidity, etc. For instance if this test was done in Denver (mile high) on a hot day, the numbers could be way down. at sea level on a dry cool day, it would be higher. Always ask for both the actual and corrected numbers so you can compare corrected numbers across the country.
The drop from test one to test four indicates that heat is taking a LOT out of the car. So they didn't have a decent fan or ventilation, or allow enough time between tests.
I will dyno mine when I get it just to see what happens.
Here's the results from today! I do not know anything about dyno's....I have no idea how accurate this is. The operator seemed to think it was very accurate. (within reason) So + 20% = 390hp at the motor?
I would like to see a baseline pull done at that same shop with pulling the #17 fuse... Wonder how those results would look? And maybe a pull without the Jetchip? Are the guys at the dyno shop nice to work with? Prices reasonable?
Anyways, great pull, it's nice to see some numbers up here from dyno runs. =)
