I'm considering trying Sunoco Turbo Blue race fuel in my 03 CR 250. I've been using VP 50% with super unleaded pump gas @ 40:1 with Silkolene Pro Comp. The bike runs great, but I can get Sunoco Blue a lot cheaper. Will it hurt my engine to run the race fuel straight (not cut)? You guys who run race fuel, what brand do you use?

I run straight TORCO 110 w/ TORCO GP-7 synthetic oil(32:1).  I have been using this for three years now and am very happy with performance.  I have taken apart two top ends this winter and no carbon build up or gummy exhaust valves.  Of the bikes that I have, two have been modified to run race fuel i.e ported and head/cylinder mods.

even with a poor brand of race gas, my bike ran infinitely better than it ever did on pump gas!

I switched from your combo in my 03 CR250 to Philips B35 with MX2T and the bike loves me for it!

I've never heard of Sunoco Turbo Blue either?? I run Sunoco GT Plus unleaded uncut. When you mix a race fuel with pump gas your final product is unknown. Find something w/ a low initial boiling point and low evaporative rates and stick with it. C12 is a good fuel as well.
Good luck.

Using any race fuel will not hurt the motor, but you will probably have to re-jet. Race gas burns slower than pump gas which is why you have to re-jet.

use of an oxegenated fuel<race gas or not> can hurt the engine if the bike was jetted for non oxegenated fuel. Race gas does not burn slower than pump gas some fuels are being blended to actually burn quicker for large bore cylinders. Race gas is a blanket statement there are many different blends,some work better in certain scenerios than others.

I could be wrong about Sunoco making Turbo Blue, I know they did years ago, because we used it in stock cars, but maybe somebody else took it over? Thanks for the help, I think I'll stick to the race fuel. I just read somewhere that their going to put another additive in pump gas starting in March. Probably not a motor healthy additive!
