What's a good guess on the compression? Thanks Mike
with a stock brain too much lol :D dont know myself i never ran anything over 32cc and promptly melted #5 on my first blown 225 my own it had 155/ 160 and this motor was 4 years old with oiler gone
What kind of octane you have ?
30 cc will be 165 ish.
Factory stock Pro Max 225. I couldn't tell you the port height. Going to clean up the exhaust ports and chest a bit over the winter. Going to delete the vst. Saw the 30cc heads for sale and wondered where that would put compression. After the mods are done the computer will be reflashed. Need the rev limiter gone anyways. Thanks for the help. Mike
You will like that warmed up Pro Max.:D
That's about where I'd like to be. 175-180 lbs. Figure with the clean up and compression it should do pretty good.
Anyone ever put 26's ?
26cc is 180 if the bores seal
Agreed....I had 185psi on my 200 with 26’s and .75’s.....it was pretty worn out tho
Mach , what fuel did you run ? Was it worth it ?
I don't want to have to run straight race fuel in this motor.
I mixed 93 and 110 50/50. Ran good. EE carb stock porting went 116mph at River Ranch.
That's pretty impressive !! 50/50 with 110 could still get pricey. Might look into the 30cc's
