Race fuel

[slosh13]

Im looking into what kinds of race fuels I can run through my TRX to give it the most power. I wanted to see what some of you guys are running and hopefully I can make a decision. The motor is fully built for MX level of racing. Money is not a problem when deiciding on fuel but I want it to be legal for when I race nationals. Thanks.

depending on what compression piston you have, the fuels will vary. if your 12-13:1 i would run vp c12, which is 108 octane, if you are higher than 13:1 i would run vp c14, which is 110, or 112(can't remember), if you are less than 12:1 a 93, or 94 octane pump gas will suit you just fine. there is no need for race fuel if you're less than 12:1. if i'm wrong feel free to correct me.

actually klotz make a race fuel that is deseigned for stock compression 4 stroke engines that is 100 octane is supposed to give great power improvments over pump gas.im going to try it out when i get my new bike finished.

Some of the national riders in our area are using whats called ELF Race Fuel, its $50/ 5-gallon can! Its some bad stuff though!! VP C-14 is really good stuff too! I personally run TrackTek 105 oxygenated fuel in my race motor and it works really well.

VP Ultimate 4 is the best I have run.:)

those comp vs octane levels are a bit off I know talking to LAZ that they can run 93 pump in thier 13.5:1 wiseco R, Im going for the 13:1 or 13.8:1 Either way just screing arround ill run pump, mix at dunes/or long trips and race at the harescrambles.

i get it from my local Sunuco Station 110 octane, it is pretty good stuff.

Torco 110 or Sunoco 110 in mine, wait thats what my dad runs in his full out drag car too.
