Dragracing and MR9
I'll give you guys a run down of lastnight. Got 5 gallons of MR9 for the bike. I rode the bike to the track to try and run as much gas out as possible. Gas light came on about 15 miles before the track...ok no biggie..alittle unleaded left..i'll put some mr9 in it and see what it will do. First pass 9.36...ok not great but not bad. Hot and humid day. Second pass...9.42 wtf...turned pc up a few bars....9.43....60's are wayyyy off....hmmm...turned pc full up on high side...9.42 Didn't help. The bike traps 147 which is average mph but et is off a good 2 tenths. I took it to the gas station put 2 gallons of reg unleaded back in it.... 60's come back to 1.47-1.48 ( was 1.58-1.59 on mr9) and it drops in the 30's. It's still humid but the weather cooled alittle. The bike ran the best mph of the night on mr9 but it killed the 60's and the et...what gives? I cleaned the pipe out before a pass and when i checked it after the pass it looks to be running lean, even with the pc on full. Will i have to tune to run this gas or am i a douche and doing something wrong? lol the only thing i can think of was when i had it dyno tuned it was hot and humid....the bike ran it's best the other night in cool weather when i took it up 4 bars on the high side. Is the MR9 making it run too lean and i can't add enough gas on the high side? The bike never see's anything less than 9 grand on a pass.

I think Mr9 takes a total remap to see the benifits, but I'm not sure. I only say that because brock sent me a total different map for mr9. But I can't find any around my area so I may never know if it helps. I always hear about a tenth faster.

MR9 does NOT require any re-mapping. It will pickup about 8rwhp just by pouring it in the tank. If you didn't see MPH improvement, it was your riding or the atmospheric conditions, but not the fuel. If you had made back to back 93 pump gas vs MR9 you would have seen a difference.

I dont have a PC in my 12 just a pipe, gearing, and mr9...There is an instant difference in power when I add the VP in compared to pump gas...
Dont know what to tell you Bu...I think you may have not added enough mr9 as it was mixed with the pump gas, when the gas light comes on there is still 1 gallon in the tank, so how much VP did you add???...You should have made a few passes with the light on, then added the mr9...Best thing is to drain it or run it till the bike runs out of pump gas then add the mr9, I'm sure you will notice a big difference then!!!
There's always next time...

well the light came on about 15-20 miles from the track..so i would say i had about half gallon left. I poured about 3/4 of a gallon in the bike on the first pass. After that i put about another gallon in the bike...nothing. so now i have about 2 gallons of gas in the bike. I put 2 gallons of regular gas back in the bike mixed with the mr9 and everything was back to normal. I havent given up on it yet. I will try next week and see if it was the weather...but to be honest i think it's running real lean..is mr9 leaded?

Fresh mr9???
Yes it's leaded, but you have a pipe on your 14 so no problem!!!

I picked a several HP when I re-mapped w/MR9. I slightly leaned out the pump gas map to optimize the MR9 map. This was done on a dyno w/ positive hard data. 188hp, 109Tq.
My dyno is very conservative. No Pinnochio Dyno Here!

CR:Yes it was fresh...straight from VP, had it maybe a day.
ZX: Are you saying it will richen the bike up on MR9?...because all i tried was to richen it up on the pc...i never leaned it out and tried it....maybe thats why my 60's were way off...to rich maybe?

Bu...I think you need to give it more time with only mr9 in the bike...
It's hard to say because of the PC, what weather was the bike mapped for???
By the way you guys need more than 1 map for your bikes due to the weather changes...You need a map for each change of season...

well see i was worried about that...Ryan mapped it in hot/humid weather...and i was thinking when it gets colder i would just turn up the gas on the high side of the pc to compensate for the cooler air...i know, kinda ghetto but dyno time is expensive. Another thing that worried me was there was no air being forced into the ram air on the bike...i know that has to change it some. I havent given up on the mr9 yet i will play around with it some more on wednesday night...i will get every drop of unleaded out of the tank and put straight mr9 in it and see what happens.

If you had your best MPH with the MR9 it was making more HP...We have way more HP than we can use in the 60 foot, so even if it were down a few ponys with mr9 it would not change your 60 foot..... I think you just had some bad 60 footers , Shit man it happens to all of us.... I run poor 60 footer till i get a few passes under my belt everytime i go to the track .... I kind of have to get warmed up........Smokin...

sorry i got cut off on that last post...anyways...my sixtys went right back to 1.48..1.47 after i mixed unleaded back in it. I figured it was making good hp but maybe it was running lean/rich and was killing torque....maybe??? Trying to figure this out... you guys are a big help though...thanks!! : )

1.48 to 1.58 is a result of your clutch and throttle control not MR9 - net ET should reduce about .175 to .185 on slower launches..... KSP

I thought about that too...but making 1 pass with reg gas and doing a normal 60 then switching to mr9...then making 4 passes..all crap 60's...then switching back to regular gas...made 3 more passes and having my good 60's back....so....

Rational conclusion - appears to coorilate - except - MR9 is only good for about 5 hp...... which is not enough to make a dramatic difference in 60 foot times - if your top end speed was up then it is delivering the HP - and even low RPM roughness could not be an issue if you were launching in the 1.50 to 1.60 zones. I still hold with the hands despite the contrary apparent evidence - based upon dealing with my own demons at times in the past..... what were your short times can you post your best run - all data for each.

i'm going to try again wednesday because i know i'm jumping to alot of conclusions. My usual 60 is around 1.47-48. I noticed a instant drop in my 60's with the mr9...not saying it wasnt me but i made 4 passes and all were the same. I guess i'm trying to figure out the tune more than anything....i know mr9 will be better for the bike then reg gas but, i just have to get a handle on it. My normal mph is 147-148..i done this with the mr9....but....i couldnt do it when i mixed regular gas back in it...but...my sixtys came back and my et dropped and my mph was around 145. so i gained et and 6o's with reg gas but lost mph...i gained mph with mr9 but lost et's and 60's hmmm confusing. Next page back i posted (ran a 9.28) that has all the pass info

i was thinking on a good tune it's worth 10 and acouple pounds of torque...hopefully enough to push this fat guy in the 8's
