Snow perf. water/methanol

[darwin88]

I have a Saleen series IV blower and was wondering if anyone has used water/methanol injection on it? Is it safe? The kit injects in the air inlet tube before the supercharger and i have heard that you shouldn't get the spray on the rotors. If anyone knows or has suggestions that would be appreciated. Thanks

Nitrous works better
Water meth works great with turbo's and centrifigul blowers, not as good when going though the intercooler and rotors. I haven't really ever been able to get good gains though roots or screw blowers. Nitrous through a screw though.... picks up 2 psi on one of my customers 03 cobra/whipple combo's.

thanks, well i ordered the water meth for now but i already have around 10psi boost and stock bottom end. What size shot would you use? I have seen guys with kenne bell get around 25rwhp out of the water meth kits. what would the out come of using nos give?

nitrous would cool the intake charge much like the water/methanol and would add power from the extra oxygen. Some people just spray the outside of the intercooler to lower the intake charge 2.

well i have the w/m on the car and can't quite get it tuned right. I am not tuning the car for the w/m, the tuner said if the kit ever gets plugged or stops spraying the tune would be to aggressive and might start to detonate without the w/m. All i want to do is cool the IAT and the computer will add a bit of timing itself.

I have the smallest jet in and i have set the high and low spray points and it still bogs down once in awhile. The guys at snow say i should be running a jet twice the size that i have in but that would make it bog down even worse, i think. I am gonna try to turn the pump press. down and see what that does once this rain is gone and i can at least get some traction. If any one has tuned or set a w/m system please let me know what i'm doin wrong.

I'd say talk to TomaK but apparently he and his vast knowledge in regards to tuning isn't liked around here for some unknown reason.

[darwin88]

o ok is he on this site? I'm fairly new but haven't heard of him. thanks

Don't take it personal. With the internet, all you need is one bad experience and you are targeted. I'm sure TomaK is great at what he does. Take it for what it is (ie. someone's opinion only) and move on. There are a slew of tuners on this site now and everyone will have their favourite and their opinions regarding the ones they are familiar with. If you have had a good experience with a particular tuner then promote that tuner. Some folks just don't know how to control their emotions and would rather blast someone anonymously while shielded behind the internet curtain opposed to just doing what they've been told to do since being toddlers and that is that if you have nothing nice to say about someone then don't say it at all. There are too many factors that affect each one of our experiences whether good or bad and that doesn't necessarily mean that everyone will have to deal with identical circumstances.

Personally, I've dealt with Matthew at Tecmotion located here in Calgary and he is a great guy and awesome tuner.

They let me back as long as I dont talk politics or "promote my business" on Matthews forum....

I agree. The current state of the water Meth kits really is not so good that I would trust my engine to one. Plus, all the distribution issues with single point injection.....

First question I guess before I can offer a suggestion... what fluid are you using/what percentage is methanol?

Also, is it a boost referenced kit or a MAF voltage referenced one?

If your bog problem is on the initial hit, your problem is is not uncommon, however, it should generally clear up at higher rpm and as you row through the gears.

Amen to that...takes a whole lot more energy to be pissed off all the time anyway......well said John.

Not that I'm anybody, but this past weekends escapades of guys signing up on the site with numerous aliases just so they could be assh*les to each other was a waste of time. ( Don't anybody take specific offence, cause that was a general statement not aimed at anybody in particular).

What John said is true....can't say anything nice...shut the f*ck up and quit screwing with my serenity!!!

On a somewhat positive note, dropped the 'vert off today to get my long tube headers installed....geez, guess what...that has absolutely nothing to do with this thread....but, I feel better!

50/50 distilled water and methanol. It is a boost referenced kit. Sometimes it is good and i do notice as i do a full run through all the gears it doesn't bog down. Say i'm in 2nd about 2000rpm and then punch it, as it revs up it will bog down at certain rpm's. If i take off in 1st and run it through the gears it doesn't bog mainly because it revs up so fast in 1st and by the time you hit 2nd your revs are fairly high. So I guess is this normal or should i be as concerned as i am about it?

[Brownbrosperf]

I have used a few and I like the maff based ones best. That being said I don't think they are the best option on a liquid air intercooled car. Distribution through the intercooler is terrible. On a centri or turbo car it is alot better but still less than ideal.

[Tomak]

Yeah, its probably the boost thing that's causing the problem.... as the kit will psray the same amount of mix whether at 2000 rpm or 6000 rpm (ie, the full boost regions).

Without seeing your dyno graph, this is only a rough guess, but you could easily be fattening your low end mixture 7% and upper end 2.5%, and slowing the flame speed enough for the big power loss... my guess now would be that the richness plus additional cooling, plus slower burning of methanol is hurting you down low.

You could try leaning it out by reducing the percentage of methanol. Wont cost you anything to try maybe 25% and report your findings....

Good luck!

Or switching to 87 octane fuel if you are running higher octane.

[Matthew]

Personally, I think if you are willing to run 10% methanol you might as well just put it in the gas tank and turn the timing up. At least then you get an even distribution of the higher octane fuel.

I always think its funny when guys spray water or windshield washer into their engines. The fuel companies go to great lengths to keep contaminants like this out of their product.

-Matthew

BTW: Methanol is very corrosive to fuel systems, so don't put too much in your gas tank either or you will have corrosion problems and irreversible swelling of rubber parts in the fuel system. I have run a Mustang on 100% methanol, but it creates a lot of problems.
