And that's another thing NEVER trust manufactures dynos. I don't even look at them. If it's not proven by someone that doesn't work for the company you can bet it's exagerated.othick said:I've bought cams for 2 different cars from colt cams and had very good results. However those 4ag dyno graphs are pretty sketchy. There is no tvis dip at 4400rpm's? And 90whp on a 4ag with i/h/e? What happens with the aftermarket cams below 4000rpm's, it's not even on there. 24whp by just switching to some relatively mild aftermarket cams is pretty hard to believe, I think there might be some other factors going on there.
