troyzstang Posted January 6, 2014 Report Share Posted January 6, 2014 Currently running 180+ on mine. 19cc alky domes cut by Brandon ( Wildcard Racing) What are you seeing? Troy Quote Link to comment Share on other sites More sharing options...
04_blu_shee Posted January 6, 2014 Author Report Share Posted January 6, 2014 185 psi with 19cc domes. How much is too much when the motor will actually fight its self on compression. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 7, 2014 Report Share Posted January 7, 2014 Motors start to really fight them selves over 165 but depending on your riding more can be beneficial but I certainly wouldn't run a lot in something that gets wound out down log roads or a strung out quater mile asphalt bike Quote Link to comment Share on other sites More sharing options...

99michael Posted January 7, 2014 Report Share Posted January 7, 2014 <p>So what's the difference between alky domes and race gas domes? </p><p> </p><p> </p><p>I have an older trinity mx built (yes, i know) motor I got with the bike and po said to run 110,, started playing with it an I was running 205# cold. With 17cc domes.. Curious if they could be used on an alky bike if I ever decided to step it up a notch. Would alky let the bike run cooler?</p> Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 7, 2014 Report Share Posted January 7, 2014 Alky would run cooler. Ditch those domes Quote Link to comment Share on other sites More sharing options...
99michael Posted January 7, 2014 Report Share Posted January 7, 2014 <p>So what's the difference in the domes?? I understand trinity is shit.. But them 17 domes don't have that stupid swirl deal cut into it like the others I see people having problems with. Just curious if they're worth holding onto or just send em off ebay's way. More than likely eBay.. Lol</p> Quote Link to comment Share on other sites More sharing options...

Surfrjag Posted January 8, 2014 Report Share Posted January 8, 2014 170psi squish velocity is the determining factor not psi Quote Link to comment Share on other sites More sharing options...

possum Posted January 8, 2014 Report Share Posted January 8, 2014 Some builders have same domes for race gas or alky. 1 Quote Link to comment Share on other sites More sharing options...
registered user Posted January 8, 2014 Report Share Posted January 8, 2014 does he need a certain compression ratio or just as long as the gauge says 170+ then hes good to go ? not than any of you guys would know the answer but just wonderin Quote Link to comment Share on other sites More sharing options...
