I got a new Summit Racing catalog and under new products I saw this. Anyone with experience with this? Worth the money or not?

That is the kit I have on my car (Snow Performance). I am happy with the quality of parts used and the performance/protection since I don't use an intercooler. I have the one with the progressive controller.

I have a paxton sn2000 with the VR4 upgrade impeller. I purchased a shur flow pump for 50 bucks. Here is a link to a DIY water injection. http://members.***.net/stevemonroe/AlcoholInjMod.html

 

I dont have direct experience on my car, but I do have a friend with a 10 sec street car and he is running a similar Methanol Injection system. He runs a mix of Water and Methanol (40/60) in a seperate fuel cell. His kit is progressive, it uses input from a pressure sensor and the voltage output of the 1st injector. Depending on the readings from those two sources, it will begin injecting the mixture, and then also inject more (via high pressure nozzle) when the boost and injector voltage rises (increases voltage to the pump). Its a pretty slick setup and it allows him to hit 2 bar of boost (28psi) with 92 octane in the regular tank. I plan to use a similar setup when I get further along with my F/I project.

 

right now, I have my water injection connected to a hobbs switch so it will turn on at 6-7psi. Next year, I plan on purchasing the PAC controler unit which will titrate the voltage to the water pump in relation to teh amount of boost, so at full boost you get full power to teh pump, or where you want to be with the water injection unit.

see what julio at alky controll can do for you- hes a great guy to deal with. his kits are beautiful

 

This thread is geat.I have been kicking around the idea of building these kits but was not real sure how many people actually used them.Maybe Ill look further into it.

i have the smc kit .

 

anyone have a good cheap source for methanol?

 

local speed shop= 3.18 gal

Windshield washer fluid rated at -20* contains meth and will work = $1.25gal at local parts store

 

what about the sope and other stuff in washer fluided

 

no problem with soap-

Actually check around it is fairly common. The July 05 popular hot rodding did a snow kit install and used "peak" windshield washer fluid.

For those who haven't been there yet, here is a link to the Snow Performance website. Lots of good info on meth injection in the forum and of course all the details on their product lineup as well.

 

I have heard of the detergents clogging up small nozzles after some amount of time. What happens is the water/methanol evaporates too near to the nozzle, the detergents dont evaporate and get deposited right at the nozzle outlet.

Clogged Nozzle = not injecting when you think it is = boom.

this can be prevented with maintenance, but just something to think about.

 

The detergents have nothing to do with it. Think about it. Detergents, clogging, it isn't going to happen. The clogging is caused by the minerals on non distilled water.
By rights you should be using distilled water mxed with methanol.
you want to use -40 "winter" windshield washer fluid.
its high in Methanol and low in detergents as compared to the "summer" formula.

 

How large of a tank would be required for the extra ww fluid, yes I realize the harder you drive the more you will use, but give me an idea.....thx

 

The recommended meth/water to fuel ratio varies depending on several factors, but can go as high as 15% of your fuel amount. Considering thirdgens have a 16(?) gal. tank, that works out to 2.4 gal. of meth/water mix. Now considering that most of the time you drive, you will not be injecting. So I'd take a stab and say that anything over 1.5g would be overkill. Just fill it when you fill your gas tank. Now on a drag only car, that could be different, but just keep a better eye on it.

 

you could possibly use the windshield washer resevior as your tank by plumbing a line in the bottle. just n idea for a diy job

 

That's what I use, works great. I do have to refill it if I'm getting into boost a lot.

 

Is methanol safe for the catalytic convertor or will it ruin it?

 

Methanol will not effect the cat. It is a clean burning fuel.
Much less soot (carbon) than gasoline.

 

That's great to hear, because I want to run this system with my new WEIAND blower to prevent detonation. I like te idea of using a stock windsield tank to hold the juice and keep a neat compartment. I'll have to get a new one. I removed mine years ago.

 

Call Doug or Chris at east coast supercharging they can answer any and all ?

 

so is this really only for engines receiving boost, be it through turbo/ super charger?

basically, would it make any sense to throw this on a mostly stock engine? or would that be pointless?

 

It is pointless to put it on a stock N/A engine but for a Very high compression (1:12 or higher) N/A engine it will be helpful to use if your using pumpgas such as 93 octane. It will basically raise the octane of the fuel mixture and fight detonation. So if you got a race gas only motor and need to run on regular pump gas this might be helpful.

 

so its more of a prevention concept than a power booster?

 

It will act as a intercooler, thus a power adder, for boosted aplications but on a N/A motor when the air charge is already the ambient air temp it wont help much in cooling down the air going into the motor. It is mainly to prevent detonation on a N/A motor.

 

I'm thinking about putting alcohol on my own car again. Last friday I dyno tuned a mustang wtih a anderson mr. freeze kit.

The Mr. Freeze kit doesn't use a pump but boost pressure to push water back up into the intake (pre-blower) via small hose barb. It ws a really cheezy system to say the least. The guy even used washer fluid

Even still the car picked up 50rwhp!!

 

any idea what it picked up at the crank?

 

no?

 

Well considering, correct me if I'm wrong guys, but you lose 23% of power through parasitic loss of the drivetrain. So 50 * 1.23 = 61.5hp gain at the crank is what I get.

seems apparent that if you have a boosted engine, methanol injection is worth it.
