what fuel would you guys get first between O'Donnel, Sidewinder, or Blue Thunder Race Forumula??????? and why would you put them in that order?

and what types of problems are you talking about with the Rossi engines have problems with OD fuel...i no many people running OD in there Rossi's and dont have anything bad to say about them......

thanks

Mike

Run the O'Donnel, its a little more expensive but it is definately worth the extra money. There is nothing wrong with Sidewinder or Blue Thunder, however, it comes down to personal preference. When I ran the O'Donnel I noticed more power on a big track, and the engine's piston and sleeve are still spotless after over a gallon of fuel.

Just my $0.02

I've had great luck with the Byron's ($22.99 for 1 gal. of 30%). I left my buggy engine all winter with just a few drops of after run in the cylinder and the internals were spottless this spring. The areas of an engines internals that you should be liikong at are the bearings. If you leave unburnt fuel in the crank case of any engine, no matter what kind of fuel, rust will start forming on the bearings.

I think im going to buy some maxy tommorrow. Im going to be taking the car out to a track here in florida as well. Should be fun.
Had a black magic that would get to 265 deg without clearing out on O'donnel. Made great power well below 200 on Race BT (same day). Rossi engine has VERY close tollerances, might be a factor. I sold lots of Rossis too, all drivers using O'donnel had troubles...

Wow so the race BT was running a lot better below 200 and @ 260 with the OD it still wouldnt tune out?

I was having this sort of issue. Real bad idle , always flaming out. Couldnt get a good rip until the car was basically on its way to overheating.

That's right! I have never seen such a difference in tune (one fuel vs. another). Most engines won't show such a big difference.

Yup, O'donnel.

MAX P7 .15 7 ports
RB .15 Evolution

O'donnel 25%, Tornado 25%, doesn't matter.
