o'donnell 30%

Go Byron 25% or 30%. Also remember that once you go up in nitro %, your piston and sleeve change (expand larger slightly) so you can never go back down in nitro, or you'll lose compression.

u can always replace the p/s if u have to

yea I knew that but thanks. I didnt know that the piston and sleeve expanded though

[kevinF]

when I go up to 30% should I richen it and if so how much?

currently im running 20%

[bigjs]

just run it with the current settings first to see how it performs, then adjust based on temp and smoke

I say traxxas 33%

[kevinF]

tex the only pprobllem is my LHR store doesnt carry top fuel so I guess I got to go to hobbytown for my fuel.

is that what you run tex?

+1 for the Traxxas 33% Top Fuel.

[Tex]

no but out of the fuel you said you wanted, thad be my choice.

I run Trinity Platinum 30% from LH

[Michowski]

traxxas fuel is awesome. I ran a couple gallons in my old 2.5 and it really woke up that motor.

But not the 20% Top Fuel....just the 33%, right? I've heard lots of guys say the 20% has too much oil for good power output.

im running byrons now, i like it and they sell it at the track.
