Non Pump Fuel
- Thread starter CDN-GTR
- Start date
If you don't need it, your wasting money. I used U4.4 for awhile because my bike was mapped for it when I purchased it. $200 a weekend in fuel and I would have gone faster putting a new rear tire on my bike instead.
I was buying it at Oshawa cycle salvage or the VP fuel distributor.

My neighbour gave me some left over MR12 to try last year. My bike burnt through it like candy, but oh damn did it make awesome power!! I had to remove my wideband o2 sensor because it can damage them, but other than that, I left everything the same as when I run Shell 91.

Mr12�� its like crack! Kennedymotorsports. Michelin dealer. Or pro6. Its not cheap. It is poison. It stinks up your garage and house and trailer. But when its that good at making hp. Its worth it. I think this year its $200 per 5gal
Define not too pricey

Love MR12, also love that a sponsor pays for it.
What gains did you get from it compared to pump?
When we were done tuning , 9 hp over pump. However my engine has cams and thin head gasket. So it did really like the race fuel
When it was a Stock motor , the gains were only 3-4 hp but the throttle response was night and day over pump
This used to be my signature, but Paulo didn't like it.

That's pretty decent for a cheaper fuel. We ran it in the 600 for two weekends and after looking at the $500 fuel bill after two weekends decided it wasn't worth it.
Is that because of the size of the pistons? 12.8/1 compression isn't much.
I'm afraid to try race gas in my bike. It was tuned for U4 (I think), but the mechanic I bought it from said it will run okay on pump gas, it'll just feel "soft". I'm afraid to try race gas because I'm pretty sure I'll really like it and then track time will cost twice as much. LOL
What HP are you running on that bike? 165?
177 crank, 171 wheel

How did you measure crank hp
He has been dyno tuning for 15 years , it was his educated guess based on years of experience building engines and dyno tuning
Obviously it's not 100 percent but seems 6 whp loss is around right with light weight rims
