Race Gas

Racing a gsxr 750. If I run race gas do I need a fuel MAP? and is race gas higher octain? If so do I need to change my timing?

For all intents and purposes, you're money away running race gas unless you're engine builder told you that you needed it.

For most race fuels you will need a map for them to run properly.
FWIW most fuels won't give you anymore power unless they're oxygenated, which play on fuel system components.

VP makes literally dozens of types of fuels. Which fuel is it?

If you're looking for instant HP without a map go with vp Mr12. Its oxygenated and rated at 87 octane. You won't gain as much power as you would with a map but it does give you a boost. But at $25 a gallon I would want to get the miost power for my money.

$25 a gallon?? Holy . LOL. For the uneducated, what would the oxygenated fuel do to the system? Would it induce corrosion or something?

Short answer, yes.
Add to that the reduced lubricity and pumps fail among other things.
IF you do run any oygenated fuel, I highly recommend draining/purging your fuel system between race weekends. No doubt, the stuff is awesome for adding that 3-5 hp when properly tuned mapped, but there is a cost involved, both from the initial buy in and from component wear/failure.

all a power commander is, is a device that allows you to change your fuel map adding or subtracting fuel in certain rpm/throttle position ranges. Its used to fine tune a bike. PC does not have a map for "race gas" because there are a million different race gas' out there and everyone needs to be tuned differently

Someone correct me if I'm wrong but I believe the Motorsport 109 at cresson is oxygenated, however it wont run like that MR12.

it is oxygenated. A buddy of mine dynoed his bike the same day with both fuels and MS109 only made 2hp less than MR12 and cost $10/gal compared to $25/gal

i've heard of a few people trying the shell URT with good results. it's very nearly the same stoich value as 93 pump gas, so pump gas lambda will work. i think it's only like 3% off. which simply put means you don't HAVE to retune for it. and i think it's somewhere in the neighborhood of $15/gal.

oh and it's not oxygenated.

Some classes have restrictions on fuel so make sure you can legally run the stuff before going to all the trouble!

Bad idea? No.

Complete and utter waste of money? Yes.

If you can spare the cash do it, that way next time you can make your own decision based on results and not our opinions.

oxygenated fuel will make a noticeable difference for sure. I picked up 2-3 mph in the 1/4 on VP MR9. It didnt change my ET much but I trapped higher speeds

I used MR12 this weekend at TWS (Texas World Speedway). I mapped it all morning. By the end of practive I had went down another tooth in the back. My lap times and dyno tell me it was money well spent. I'll also say that in 4 years, last weekend was the first time I really ran race fuel. There is so much more to work on that a few more HP couldn't fix for me. Now I'm getting to the point where I can put to use the few HP gains.
Plus it smells beautiful.

You should be able to get to the front of a race on a stock motor with pump gas. Particularly with a 750 in the b classes which are mostly 600's.

But to answer you question, yes.. a map helps to maximize the gains. And no, not all "Race fuel" is higher octane.
