Not many Water/Methanol kits...why?

[1CrazySledder]

I'm wondering why I haven't seen that many kits installed on your sleds? I have been researching on these for the last few days and seems to me it can only help us out. We can run higher boost numbers with 89 octane fuel with a stock motor. The water/Methanol has a freezing point of -65, so that's not an issue. Is it that there isn't anywhere to put the 2 qt or 7 qt tanks? These kits bring out intake temps way down, which is better than heat going into the throttle bodies.

What am I missing? One of these kits are half the cost of pistons.

Help me see the light....

I think the weight of the kit scares alot of people. Your packing alot of extra hardware with a good water meth kit

LOL...

I'm thinking, ( Which is usually a bad thing ) if I'm pushing an average of 240hp, who cares about a few extra lbs.? That's more hp than most cars have at a fraction of the weight. One of these kits would pay for itself in a season or two, so a person could take the savings and buy light weight parts.

You may be correct tho. I know allot of people are concerned with weight. I hope this wouldn't be the only reason tho. Would weight be enough to tip the scales to not invest into something like this over the advantages?

I think the main beef I would have with it is reliability. Your tuning the sled way past safe limits with it working and if a jet ever plugs or a pump freezes up over night and you take off the next morning, bang!

Its a good way to cool things down and say on a SC sled use premuim fuel and 12psi or something but I would want uber saftey features and the SC would require a pulley change to not blow up say if the system failed and gave a warning, you still have to stop and change pulleys, or find some racing fuel. To me it would be the PITA feature. I want to gas and go not mess around with the thing all the time.

AHH. Here we go now. Never thought of having to change my pulleys back around. There is a device ( Yep, 1/2 lb more. lol ) that will set off if a line gets clogged, run out of fluid, what ever the reason. A warning light lights up and turn the sled back to normal operation. I didn't think about the pulley thing. I haven't installed my blower yet, but the pulleys seem easy enough to change.


I'm just trying to build THE BEST ULTIMATE sled I can the first time around and I am researching every possible angle I can find.

Thanks for the input this far.

Your just trail riding in Wisconsin right? 5-6 psi is all you'll be able to handle. That is about what mine feels like on the 80 hp shot and there is no way I could ride those twistys with that much power. You'll really be able to open it up on a lake but then those aren't always safe and smooth either. I really want a SC but the nitrous works for my style, its calmer and easy to control off the bottle and on it demands lots of white space and its a monster that will give your SC beast a run for its money.

I tend to do the same thing as you reasearching things to death adding anything that will make my toy better, faster, etc. But a fuel injected supercharged sled is no joke in those tight trails in WI that I love so much.

I dont know about using it on a trail application, but I have meth injection on my alpine t-apex and it works real well. The best thing about it isnt the extra hp its how much cooler your sled is after puling a long chute in deep snow. After being taped to the bar at 18lbs for 12-15 sec things get real hot, there is a noticabe difference when you run meth to keep things cool. It also allows the sled to run 2lbs of boost less and make the same power.

I think I am going with a kit. Just for another added safety measure. For 250 bigs, why not? I'm going to have it switched so If I know I got a hold of some bad fuel,( My parker box lighting up ) I can turn it on rather than taking it easy until I get better fuel.
I also have a air temp gauge with two sensors that will tell me exactly what my intake temps are on and off the injection. When trying to race this sled, this injection will really come in handy for that first second on the gas. I won't be pulling in hot air from sitting there on the line waiting and letting the IC get hot. All the negatives are out weighed by a landslide by the positives. For me and warped mind anyway.

Thanks for all the comments this far...

Whoa, guys slow down here!

There are many myths about water meth injection systems and how much power they make.

I install systems on Super or turbo charged vehicles that DON'T have an intercooler, this is a poor mans intercooler kit.

They suppress Knock by lowering charge air temps, this works well when charge air temps are 150 degrees F and up.

We can stop knock but also lose power unless we make it up with more timing.

Because they are pissing on the fire, and causing a rich condition depending on mix of water and meth.

There Is power in advertising when they leave out all the details.

Now these snowmobiles have intercoolers and charge air temps are really low to begin with, almost to the point of Freezing, throwing more water in the mix can be disasterous IMO. Freezing Carburators comes to mind.

Now, Unless your running Straight Meth there is not enough Octane added to run lower Octane fuel on high boost.

I have never added a Water Meth kit regardless of mixture, and gained power unless I tuned for it, You might be able to find that in the fine print somewhere.

Although Water/meth may be benificial in a lot of applications I don't think Snowmobiles are one of them unless your running on asphault on the summer months.

Thanks for the info Ted!!!

 

[1CrazySledder]

Okay. Thanks for blowing holes in my idea before I spent the money, Ted. lol

I'll still note the intake temps I get at certain outside
( Atmosphere ) temp. Hopefully they are cool enough.

This is my first boosted sled, so I am still in my learning curve. Just trying to think of everything.

Thanks to all,
