What fuel is everyone running here on their engines?

I am running Sidewinder 30%/10% pro and with my Elite 8 I will run in 2016 I am considering a change as no one locally seems to run it although 2 major hobby shops have lots of stock of it.

Would like to see what some of the regulars here say they run.

Sidewinder is good, Byrons, or Bones Brew are also good. I have seen some engines come through my shop not looking as good as engines with these fuels.

i had bad experiences with sidewinder ,i am now using byron or o donnel

What about VP Powermaster or Werks Fuels?

Werks is great fuel, I have seen some awful looking engines ran with Vp.

angreed also with 22 racer, vp fuel has only bad news and roumors ,werks is good quality fuel. there is sometimes a diference of what we want to use fuel for ,profesionaal use ,club racing ,bashing and having fun.stability and runtimes are winning races .most of us we need long lasting engines .tessman was using vp power master 25 but he has the ability of changing parts and engines when ever is needed .....

Hi guys,

My brother is currently running a Nova PLUS.21-4BTTSWC. How does the new Nova Mito 4 and Rex Legend 4 compare to this engine?

Thanks in advance!

I have never owned a WC - but it's a pretty well respected motor, and the last of the real ballistic motors. It also uses a regular bearing, so bearing changes are much cheaper.

The Legend 4 is the evolution of what he has - much smoother and more toned down. Uses the weird expensive bearing.

The mito is a much longer stroke.

So a BTT and a Legend 4 are nearly identical engines, they have the same piston and sleeve but have different crankshafts... The Legend 4 has a onroad style crank with a large bore and double tungsten slugs whereas the BTT has a offroad crank with a smaller bore and no slugs..... Sometime in the next little bit I plan to dyno test my Legend 4 and will swap back and forth between a BTT and Legend crank to see what the difference is....generally speaking the larger bore crank has a smoother throttle response but makes more power and RPM...but usually a crank like that is in a engine with higher timing and more aggressive porting, so we will see what the results are...

Neal, is there any timingdifference between thoose two cranks?

VP and Werks are mixed in the same factory. Pick your poison.

Just a comparison you can make with the parts to see if you really want to try it..

A big thank you to Socket, Maximo & kgombe for the detailed info.
Looking forward to seeing the result of swapping those cranks!

Hey Rex, got my Rex Revenge this week. Great looking engine, started breaking it in today. Awesome deal for the money..
