nick t Posted May 4, 2008 Report Share Posted May 4, 2008 ok i was talking to the guy that does most of the work on my bike about a cool head. we were actually talking about a friend but we were on the subject. i asked if he had one layin around my buddy needed one. he procceded to tell me that he doesnt suggest it. he said that there are other better ways to make sure your engine doesnt run hot. he said something about a water impeller or something about the water pump part. what do coolheads do? are they worth it?

peak-j Posted May 4, 2008 Report Share Posted May 4, 2008 I'm not sure how much they actually help temp. wise, but I like being able to change out my domes if I need to. Quote Link to comment Share on other sites More sharing options...
mopar1rules Posted May 4, 2008 Report Share Posted May 4, 2008 the water pump impeller that your buddy is talking about is probably the vitos. it is suppose to pump coolant faster i believe. Quote Link to comment Share on other sites More sharing options...

In my honest opinion. The cool head does cool better, and gives you the bonus of regulating youre compression. I ran one for 11 yrs now thing rocks!

nick t Posted May 4, 2008 Author Report Share Posted May 4, 2008 so the different heads or domes changes the compression? what does that do? Quote Link to comment Share on other sites More sharing options...
2001Stroker Posted May 4, 2008 Report Share Posted May 4, 2008 so the different heads or domes changes the compression? what does that do? Domes come in cubic centimeters (cc's). The smaller the number cc, the more compression. It makes a smaller combustion chamber. You get the head, and removable domes. So, you can change them out for whatever riding you plan on doing. 17cc would typically be the smallest dome, with the highest compression. Most people on here, from what I've read, use 21cc domes. Personally, I have 18cc's. And yes, they do cool somewhat better, but higher compession makes more heat, and calls for more octane. I vote to get it. I have a ProDesign, and love it. Alot of people on here use NOSS. Personal preference. Quote Link to comment Share on other sites More sharing options...
nick t Posted May 4, 2008 Author Report Share Posted May 4, 2008 1. what is the difference between the two brands? 2. what does more compression do like to your power. more/less or is it just how it is delivered? Quote Link to comment Share on other sites More sharing options...
mopar1rules Posted May 4, 2008 Report Share Posted May 4, 2008 more compression gives you more low end torque. to be safe on 93 pump gas, i wouldn't run a dome smaller than 20cc. one of my buddies has 19cc domes on his pro design, but he runs a 50/50 mix of race gas and 93 octane to be safe. i hear from more people that the noss machine head is better, but i think some of it boils down to personal preference. the smaller domes would be more ideal for high altitude situations, and the larger domes for low altitudes.

nick t Posted May 4, 2008 Author Report Share Posted May 4, 2008 ok when you say 93 octane, do you mean just 93 octane? no premix? the guy i bought my bike off of said i could do that with high enough octane but the guy who set it up for me told me to run like 50:1 or something. all i know is i dump 100:1 oil for 6 galloons into 5 gallons of gas then put it in my quad.

WHAT?????????No matter what octane you use, you still have to pre-mix oil. 32:1 is a good all around ratio. 4 ounces of oil to 1 gallon of gas. That's what I mix, and so do alot of people on here. NEVER run straight gas. Quote Link to comment Share on other sites More sharing options...
