just wondering, we did some dyno testing on a spec stock type race motor and loss hp the colder it we got it below 180.


I did not say we lost power with the aluminum heads. With the aluminum it disapates the heat in the cylinder better than steel to stay away from detonation. On the dyno when you run the engine hotter you are getting the oil hotter also that will make a little extra power because the oil is thinner. When you put your 180-190 degree motor under your engine hatch and go boating in 80-90 weather the air going into the engine won't make the extra power you seen on the dyno.

crockett, i was asking about the difference between steel heads and alum. i'm running aluminum heads on a race motor and and steel on another and the found that, and also told that we could run more compression with the aluminum heads compared to the steel. since the aluminum disapates the heat better before running into denoting issues. we switched from 8.25 to 10.2 and gained quite abit of hp.

my point or question is could you run 10 plus compression with that motor(more like 11) and get away with it, using the alum. heads and 120 on the water temp?? and still just 93 pump
