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?

just wanbt to make sure I got this right. I have a stock 04 GSXR 1000 with a sidewinder and a brocks track map. Do I need it remapped for MR9 or MR11 or can I use the map already installed.

Track map is for MR9, MR11 and MR12 with air filter removed, if you have the track map installed you do not need to remap.

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

07 GSXR1000, sidewinder, strapped, 64"

7-10 HP gain, can make bike harder to launch because of increased power so it would depend on the rider.

For those that haven't tried the MR12, I've been running the MR12 in my 08 Busa for 2 weeks now. I was running MR11 prior. I spoke with my VP folks out here in Phoenix to find out what the difference was between the two fuels. I was told the new MR12 is more oxygenated that the 11. I can honestly say I love the new stuff (and it smells good!). From 89 (9.50's) and MR11 (9.40's), I ran 9.28 (about 100F and on a HOT slippery track) with MR12. 60ft went from 1.49-1.52 to 1.40-1.43. I can really feel the bike pick up right off the light (on my setup) Shooting for 8's when the weather cools off this year. My opinion, VP just made a heck of a replacement for the MR11. I highly recommend for all you MR fuel guys. You won't be disappointed. Also, as reminder, you still need to drain the tank after use.
