MR11 vs. MR9 vs. MRX01 

I have found as long as it is in a sealed container and kept very cool...It lasts a couple of months...but I would not bet on it, sometimes it goes bad very quickly...and make sure its in the metal can it came in, because the plastic jugs make it break down sooner.

Let me know if you have any other questions.

  Its sitting in the cold side of our shop so its about 10-30 on average so i hope it will still be good, or othewise what a waste.  Thanks for your input !

07ZX14,

MRX01 should be great for you.

Nicks1

You could see about 190 with good fuel.

I'm trying to order some MR11 for out here in AZ. I'm assuming the MR11 runs great in the 08 Busa's right? 

Hotboi74,

We use MR11 now since MR9 cannot be found, it works best with our track map and air filter removed at the dragstrip, works great in the 08 Busa.

Do not leave in tank, drain the best you can and run pump gas through the system.

Yeah, I'm using the track map w/ 91 octane (ran a 9.49) and it is awesome!!!  Can't wait to get ahold of some MR11.  Thanks guys for the info.  

We have not tired Q16.

Here is VP's description:

NEW! Q16
Q16 will work well in any drag racing or circle track application -- naturally aspirated, nitrous or blowers. Q16 is highly oxygenated, requiring a 4-6% increase in fuel flow, which will make 3-5% more power than competitive 116 octane fuels. Q16's oxygenation will significantly expand the range of air/fuel ratio acceptability, so performance will be more consistent and won't vary as dramatically with altitude or density changes. For bracket racers, variations in ET from run to run will be substantially reduced. This added fuel flow also effectively increases its octane by 6-8 numbers above its standard ASTM octane rating.

• Color: Yellow
• Oxygenated: Yes
• Motor Octane 116
• Research Octane: 120+
• Specific Gravity: .716 at 60° F

I ran Q16 in a 2006 Busa with Piston slip kit 13/1 compression this weekend at Maxton, NC 1 mi top speed run.  Temp was 97 degrees--very hot poor air.  My top speed after 6 runs on Sat & Sun was 172 mph.  I have hit 192 & 194 mph without nitrous in 2008 & 2007.   this weekend I had 4 size 20 jets screwed into throttle body's.  Nitrous didn't seem to help--just made for a bucking pull.My 1st run was all motor on Q16 & I was still in 5th gear at 169 mph.  Re-dyno the bike in Columbus today at 232 rwhp.  Sprockets were stock 17 front & 37 rear.  Thus I am not a fan of Q16.  My 190+ runs were using Q4.

MR11 is 90 octane

MRX01 is 98 octane and works well with nitrous.

Use MRX01

Hi,i call from Greece-Europe and i have one Question about who VP fuel is better and give more power to my BKING,leaded or unleaded(we dont have rules about fuels)Stock engine,brocks sortmeg,K&N,PCV,Dyna Arc-2,Factory stacks,Factory +4 advancer.Here we have in stock VP fuels; Mrx-01,MR9,MR11,C12,C14,SV-05,MS109,U4-2,REGARDS

Anybody try the new MR-12? VP claims 5% more HP than MR-9!

Brock,

Do you plan on testing MR12 v/s MR9 soon? I have stock motor 07 zx14.

I see that they are making a new MR12 is this about the same as MR11? And will my maps pretty much stay the same?

Thanks

soetje & cbr9rider,

The MR12 is very similar to the MR11, same octane rating and both are oxygenated, we have not tested the MR12 but the MR9 & MR11 both work with the same mapping so the MR12 should work fine with our track map.

All are leaded fuels.

Thanks one other quick question.  Does these need to be drained out of tank at end of day?

What kind of E.T. difference will the MR fuels make over 87 pump gas?

07 GSXR1000, sidewinder, strapped, 64"

Yes, same as MR9 & MR11

No and we will not test it, E85 (85% ethanol) does not make any power.

It has an ethanol content which is far too high compared to standard fossil fuels. It’s 85% ethanol and 15% pump gas.

E85 cars are actually closed loop and will self compensate by adding additional fuel on the fly. Bikes don't work this way, I believe it could cause engine damage from an excessively lean condition.

Swiftkart,

EJ did not relay my answer on the subject correctly, my apologies. 

Most current motorcycle fuel systems cannot easily support the additional fuel volume required to run E85. Currently, the proven exceptions to this rule would be the ZX-14 and the BMW. Our testing on (dual injector) Suzuki’s found little or no additional power gain due to the inability to properly deliver the correct A/F ratio on the dyno, which was even worse during the longer run time on the track, hence the (very general) no power statement. FYI: These tests were performed with single power commanders using the stock fuel systems, as we are in the bolt-on/plug-in business. Given enough time, expense, hassle—the power increase noticed from the higher energy value of the ethanol (combined with the reduction of inlet temperature) is undisputable. 

Because bikes do not have the ability to instantly adapt between E85 and pump gas, as a car would, and we do not consider forcing a customer to deal with any number of expense-adding/complicated means of adding an additional map, just to get home without fouling his plugs if they can’t find an E85 pump… we don’t support E85 mapping. For race use, we haven’t seen enough of a performance gain to justify the additional work/trouble/technical support issues for the minimal number of customer requests. BTW, the total number of requests is less than a handful since E85 was introduced. 

Although more expensive, we suggest powerful oxygenated race fuels, such as VP MR12, for an instant/measurable performance gain with very little additional trouble. 

I hope this helps clear things up.

I agree with you, most stock fuel systems won't work with the fuel, I am going to try some MR12, from what I'm hearing, it should do a lot better than the E85.

Thanks
