Image below. Not sure if this is true but the guy figured the last dynorun made so much more horsepower because of something about my car being warmed up now and the computer probably corrected some figures and leaned it out some. He probably said it a little better than that, but you get my drift. Would that be true?

Also I just noticed for some reason the last dynorun they stopped it at 5700rpms and not at my requested 6500. The last run looked like it was going to continue to go up in horsepower numbers and it seems as if I was going to make more than 377rwhp sae. Am I right or am I missing something?

 

I have no idea why he would only rev the car to 5.7k. A 306 should be taken to 66-6800 rpms.

Mechanic sounds fishy...lots of things dont make sense.

As long as the oil is at a decent temp and it should make proper power. But you do want the water temp to be 165-195.


What did it make before??

 

this is the first time I've dynoed it. It was some new kid at the shop. The main guy wasn't there. I don't think he meant to stop it at 5700. But I'll be sure to watch closer myself to make sure he keeps on it. I am afraid to take it past 6500rpm with my 10308 crane springs. How do I know when I start to get valve float?
