SlowMoe Posted January 12, 2017 Report Share Posted January 12, 2017 On, for example, a 4 mil serval/ cub.... What kind of difference in HP can you expect going from pump gas domes to race gas domes? Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 12, 2017 Report Share Posted January 12, 2017 Easy 5-10 hp. The results compound the bigger the motor gets. Also, even better gains running oxygenated race fuel. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 12, 2017 Report Share Posted January 12, 2017 Taking my old 69mm bore 4mil from pump fuel to race fuel went from 76 hp to about 87 hp. Just domes and timing Quote Link to comment Share on other sites More sharing options...

bluebanshee98 Posted January 12, 2017 Report Share Posted January 12, 2017 What are you planning to do with fhe bike? You can make plenty of power with that setup on pump gas Quote Link to comment Share on other sites More sharing options...
SlowMoe Posted January 12, 2017 Author Report Share Posted January 12, 2017 It's gonna be a 7 mill cub. Probably 50/50 dunes/drags I know it's not going to be the fastest but if I am faster than sa a fully drag ported stock cylinder bike I would be content Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted January 12, 2017 Report Share Posted January 12, 2017 What are you planning to do with fhe bike? You can make plenty of power with that setup on pump gas I just want more power. My jugs will be ported again (timing). I bought the lp for a reason, you have room to play.

special06shee Posted January 12, 2017 Report Share Posted January 12, 2017 A 7cub dune bike on any gas will get crushed by a full drag stock cylinder. So dont get your hopes up. unless your talking a drag port stock cylinder in a heavy dune bike. Quote Link to comment Share on other sites More sharing options...
SlowMoe Posted January 12, 2017 Author Report Share Posted January 12, 2017 Yeah im not talking all out drag frame etc. Like your average stock cylinder bike with a drag port n alky Quote Link to comment Share on other sites More sharing options...
SlowMoe Posted January 12, 2017 Author Report Share Posted January 12, 2017 So without running a lockup/ super aggressive tires, would it be worth running race gas on a duner (would I be able to get the extra HP to the ground)? Quote Link to comment Share on other sites More sharing options...
