Fuel system needed to do this becomes the issue. OK on a pure race car that can be drained and flushed after every track visit. Maintenance is the issue.


Thanks Howard..

Great thread howared coleman

Howard. I think you miss understand me,'

I have

1: tuned to the limit of the stock twins
2: tuned to a very lean mixture
3: advanced timing to a high state.
4: taken advice from aquamist
5: taken advice from the company that sells methanol to the pro dragsters

I dont see many other points tho. I know through my own reasearch that there is a more powerful blend ( this is not a discussion )

I have learned a great deal about methanol this year from one source or another ( not from automotive suppliers )

I have metioned a few times before about the floors that i have experianced. In the UK i have the advantage of large tempertaure changes etc.

I am yet to see a system that can adjust for temp at the same rate as the ecu
Also one that the pressure at the nozzel does not drop when the delivery increases ( at below 60psi the oil heating jets will not atomise correctly (( m rated jets)) )
I am still trying to get propper atomistion over the secondaries
Map based syatems still seem to inject to much liquid after peak tq for my liking.


This is not a dig. howeva i have tried to trouble shoot this idea for a while now with little success and very little help. I really dont think a 3rd party system can deliver in this way. It simpily is not stable enough. On the strip i can vary as much as 14 % on a otherwise stable fuel map. this can sap lots of power as you know.

I am still trying to perfect the art of AI but with a much re designed system.

ps i know of people that run pure meth, they run normal fuel systems but flush it out at the end of the day, Thet do this all year long with no probs.

scott,

i appreciate your efforts.

my take is that you are turbo limited. as such, the cooling and additional octane of methanol will do little good when your compressors are supersonic and cavitating. the stock twins just won't make much more than 15 psi without enormous cavitation and super heated AITs. you can run them on nitromenthane and they will act as a restrictor plate which all turbos are at some northeast point on the compressor map. they just will not flow another cfm.... burning oxygen is where it's at and those turbos won't deliver more oxygen after a point which is way down from the motor's flow capacity.

speaking of pure methanol. my friend Jose Le Duc runs a 2 rotor methanol (only) RX3 drag racer. it is a wild ride. he ran 170 mph at the Nopi Nats a few weeks ago and had to lift 3 times during the run so there is more in the car. i think i remember that the car weighs around 2190... if you do the math you'll find that the 2 rotor is making alot of power.

alot.

no intercooler BTW. (you can't beat methanol). the motor seems to be very well behaved and in excellent condition after a number of major league runs.

you raise great points as to delivery needs after peak torque and ambient temp corrections. as to varying delivery, i would be interested in Julio's comments. yes there is a point re atomization and i am aware of Aquamists' nozzles. i just assume that i have the right stuff from Julio as he gets it done. i plan to tune it out this year and then, perhaps do a 4 jet LIM setup over the winter.

best wishes on your efforts and i should shortly have something more tangible to post.

^ razor sharp, without the nicks and cuts of a blade!!!!!!!!! high value information!!!!!!!!! much appreciated!!!!!!!!!

oddly enough,
ethanol is the remedy for methanol poisoning.

my veri cool system just came in today, very happy with it so far looks like a great quality kit and they have been helping me out already with questions that I have. Very nice people.

Few pics. Going to go with stainless steel in the engine bay though to bling it up a little bit The kit came with a gallon jug and a low level light. two questions though. If the tank is going to be mounted in the truck do I have to vent it to the atmosphere? also where do you guys get your methenol?

dubulup

don't think I'd put straight meth in that tank...

^this is what howard coleman is using.

nah I'll probably just do some sort of 50/50 mix. I wasn't planning on running straight meth anyways. But thanks for the link just incase maybe later on I deside to go all out

FYI i picked a Jaz 4 gallon poly fuelcell and find it fits well/ $107 from Jegs.

http://www.jegs.com/webapp/wcs/store...tegoryId=29395

since the engine compartment is approx 140 degrees i would recommend it not be the place for your cell. also, should you decide to run straight methanol i wouldn't recommend a plastic windshield wiper container. yes, the container must be vented to the outside.

thanks howard i appreciate that info. I'm going to run a 50/50 mix for now and then ramp that up later with a fuel cell type deal in the back. for now i'm just happy I got the kit and will be able to boost a little higher than regular on pump gas. Shooting for 20-22psi on pump.

GreenMean937

i actually just orderd the same kit..... hondahater .. but i think i might just get the full meth treatment !!! that fuel cell looks great ... ill put in a order pretty soon ...

anyone thats installed it already .. ?? what would you rate the install level difilculty ? and how is everyone venting the meth tanks ??

were the easiest place to find meth ?

I always buy meth from a VP fuel dealer, I have bought water down meth from offroad places with very bad results.

On a side note, I tuned an employees To4 FC w/ meth injection a few hours ago, 20psi on 89/90 pump gas, extremly aggressive tune...

GUITARJUNKIE28

i haven't foud meth for less than $3.69 a gallon where i live.

hondahater

iTrader: (2)

Would you guys agree with this before I install it like this?

GooRoo

iTrader: (4)

That's nearly identical to the way that I installed mine.

Differences:
I did not get the clogged nozzle detector.
I ran two level lights, one by the controller (in my drivers side bin) and one up front.
I run the lights on a small flip-flop circuit since my tanks are out of sight and I wanted to know when the tank was full and also have it not go on-off-on-off when it was getting low.

hondahater

iTrader: (2)

cool! Good to know. I figured it was right just wanted to make sure from someone else that had already done it.

BDC

Uh, got any more info on this?

bump^ for howard pics of the fuel cell and sytem set-up/arragement PLEASE!! thx!!

fyi, Julio locates the filter on the output side of the pump. i asked him about that location and he gave me a well supported reason that currently escapes me.

Can you just (temporarily) run methanol in the gas tank mixed with gasoline?

Wouldn't this be easiest for most people to see if it benefits them?

I'm just running straight V-Power (high quality 91 octane) at 16-18PSI on the street and straight 110 on the track (25psi), but meth really has caught my interest.

hondahater

iTrader: (2)

well I think you have to change your fuel filter out because it doesn't take to kindly to meth but other then that I'm not entirely sure. Good point though.

YOU CAN'T POUR STRAIGHT METHANOL INTO YOUR GASTANK!!! It will not mix with gas at all. Thats just a distaster waiting to happen. You would have to drain the tank completely and then pour in straight methanol. I talked to a pro-street drag racer about this and he told me to never do this because of the above reason.

hondahater

ahhh so chemically it just wouldn't work, gotcha, makes perfect sence to me.

I've got the boostcooler kit and am running 22psi on 91 with nice
results. I think with 8.5 rotors I could go higher, but why-
the car freaks me out already. I just grin when I fill the tank
with 50/50 mix for pennies compared to $9 c16. I plan to push
the envelope next year and see how far we all can take this
stuff. Boost cooler people said it is like 116octane. I find this
hard to swallow, but makes me wonder if 30 psi is a real
possibility.
