MR12
After 7 or 8 passes I have come to the conclusion mr12 is crap.
Bently as my witness, we did everything but put it on a dyno and tuned it.
VP tech said add 5 to 7% fuel. We tried everything addin all the way up to 13%. we even went -2% from my base map. The whole time I didn't gain but .01-.02 over pump gas and lost 5-8mph....
Brock was a big help all day as I fought this problem, but just couldn't get it to perform as people talk about.
Before I spend $130 on fuel again, a small shot of spray will be next.
Granted, there was a steady head wind, but the air was too good today to not run 8's

He's going back to pump gas tomorrow so it will be interesting to see what happens.

What I don't understand is the 1/8 wasn't off as bad as the 1/4. The 1/4 was terrible...

Even if its new and sealed mr12 still has a shelf life of 6months according to my VP dealer. He just had to send back a bunch of march made mr 12

Yep........ True Statement Here.... With that said, I never saw significant gains from the oxygenated stuff.. Maybe too many old but sealed cans...

I ran the same ET with Mr12 and added 6%, 1bad helped me out, still no better then pump gas. My 8th mph went to 127 but it was 126 on pump gas in warmer air. I saw no gain.

It was MR9 that we had the issue with. I've heard that MR12 is better in that respect.
Most of the feedback that I have heard on MR12 has been positive. It's always hard to compare results without knowing the state of tune. I've definitely seen it make very good dyno power, and run very strong on the track. Even some record-setting LSR bikes are using it.
Dusty, are you saying you are adding 5-7% fuel on top of the Brock's race (MR9) map? Or 5-7% on top of your own personal map? Did you get every drop of pump gas out before pouring in the MR12? Are you adding the fuel through the buttons, or actually changing the map with a pc?
Were the conditions exactly the same when you compared the pump to the MR12?
Anyway, just some things to consider. Good luck this weekend!

Shane I believe people when they tell me they had good luck with mr12, but there are a lot of guys here that its done nothing for them.
Shane, my tuned map is brocks race map cleaned up and just a hair of fuel taken out.
We tried a map he made for someones bike for macron (rich)
Tried brocks race map
Race map +5%
race map+8%
custom map +8% ( proven over the passes, with the same 60' and 330' I made my fastest passes)
Race map -2%
race map +12%
not in the order.... You guys get the idea.

Anyone you know at the track using it this weekend, with good results? How were people's ET/MPH overall yesterday?
I have heard that even a sealed can could be bad at times, so that is always a possibility.

My results were not good with MR12 either. I picked up way more mph with MR9.

Before going to Maxton a few weeks ago I took my 14 to the dyno for some MR12 testing. Had a about gallon of Exxon 93 and made enough pulls to get a good baseline. Drained the fuel out and cycled the pump until the bike wouldn't start. Added a gallon of MR12 and made enough pulls for maximum power after fine tuning.
I picked up between 8-10hp almost all the way thoughout the range. I had no air filter in the bike and it took right at 4-5% more fuel, no air filter either on the pump gas pulls, that's what I had it mapped at.
We repeated the steps again going back to pump gas and I was back down 8-10.
According to my logger I have found out all I need is around 6% more fuel with MR12 and no air filter vs. pump gas and an air filter.
At the drag strip I've never seen much of a difference in et's using good fuel but my mph is always up.........but then I'm not much of a dragracer so your mileage may vary!
FWIW........I've had good results from MRX01 too.

I did my fastest passes on MR12 with Brock's Quantum map, I didnt see any gains on the the dyno compared to the E85 map but at the track my bike was flying!

Same here, E85 and the MR fuels made the same hp when I tested on the Dyno also, but what we did was switch the dyno to time and found out the MR fuels accelerated from the same rpm and in the same gear 2 tenths quicker so it must be a lot faster burning fuel and there's where the MHP/ET improvement must be coming from.

I have noticed a gain of 3 mph minimum with MR-12 over pump gas. Track and weather conditions
dictate whether or not more are to be had.

I have heard and seen people have have great results with MR12 over MR9. But with that being said, I have also heard that if it is hot and humid outside you may as well stick with MR9. But hearing all this makes me reluctant to get my bike tuned like I had planned.

I'm on Convinced to go with a small 15-20 shot of spray. A lot cheaper than mr9/12

You need to make a map and tune for these race fuels. Other wise your just wasting your money and time, buying and using them. And you can even damage the valves and seats or maybe even pistons if not tuned properly for it.
MR 12 will make approx 8 more HP and go faster than pump fuel if the bike is tuned properly for it. We have seen it on stock bikes, modded bikes, and heavily built bikes.
The key is proper tuning!!!!! And run them fat, they carry there own oxygen. 12.6-12.8 air fuel ratio.
If you dont dyno it with an o2 sensor or have an o2 sensor on your bike with a data logger you cant possibly tune properly for these fuels.
