ClaudeMachining Posted November 19, 2016 Report Posted November 19, 2016 Theory doesn't always align with reality. Cyl temp n water temp also are two diff temps You gay. That align with reality. Quote
Keno Posted November 19, 2016 Report Posted November 19, 2016 If you are worried about the ability of the cylinders to air cool, why not machine ribs to increase surface area? Quote
JTmachining Posted November 19, 2016 Report Posted November 19, 2016 You gay. That align with reality.Lol now ur talking with cents Quote
Big Mike NY Posted November 19, 2016 Report Posted November 19, 2016 I am not a builder or and assembler. Here is a logical question to think about. Isn't powder coating cured under very high heat? To me that would make the powder coated cylinders more resilient to heat, trapping the heat inside the cylinder easier and longer, as well as not alllowing the outside cool air to do its job cooling down the cylinders because of the powder coating. No???! Quote
ClaudeMachining Posted November 19, 2016 Report Posted November 19, 2016 In theory, yes. You have one more layer on the cylinders. But when the engine is running the main cooling system is the coolant circulating, That's why i want numbers. How many more deg F are we talking? Sleeper said he did tests but didnt give any numbers.

ClaudeMachining Posted November 20, 2016 Report Posted November 20, 2016 Yes, but i guess he also monitored the operating temps Quote
sleeper06 Posted November 20, 2016 Report Posted November 20, 2016 My spread sheets are on my wife's old iPad . I don't get much opportunity to race anymore , I'll get back to it once kids are squared away in college. My test subjects were two identically built 4 mill stock cylinder motors which were ran on gas for two seasons then switched to alky. I get every motor is different the pc coated cylinder ran 15 deg hotter at the end of 1/4 mile pass and took dbl the time to cool down . Not a big deal in a race platform . I have little to no testing in a trail bike but I do push paint over powder to my customers Quote
JTmachining Posted November 20, 2016 Report Posted November 20, 2016 Canada wants numbers to input in his computer program to calculate fluid dynamics...JP he don't need this info cause it doesn't pertain to his shit Quote
sleeper06 Posted November 20, 2016 Report Posted November 20, 2016 I didn't post my comment to start a fluid dynamics war just kinda an FYI pice of info. I've ran and built many bikes with pic cylinders with no issues its just personal opinion to my customers Quote

ClaudeMachining Posted November 20, 2016 Report Posted November 20, 2016 U use Banshee to go to store for beer Nice hun?? ;-) Seriously,i need 'real life' numbers to match theory Jt. Theory and practice should always match.If not, you got to figure it out. I trust my computer, as an example, i wrote 'John Tabata' in the input box and the prog said: Gay! So it cant be wrong. Quote
