I am thining about getting a water/meth injection system and then came across the fact that some guys are using nitrous plumed into the intake horn before the IC to cool the intercooler.
So is it worth going down the nitrous route with cooling and added power or just stay with the water/meth?
It does scare me a bit but I love the thought of it .
How harsh is it going to be on the engine?
By only using a small jet and less nitrous, less bang but you would still get the cooling effect right, and it would be safer on the engine?
Any info or your thoughts on the matter would be appreciated!

Also any one use the Nitro booster juice in their water/meth kits?http://www.snowperformance.net/products.php?p_cat=251

 

The water/meth kit is a big hit right now in the BMW community running Boost Juice....they have seen great results on SC/T'd 325/330/335/M3's. So, Im sure it would be fine for the Mini. And BTW...the Snow Performance kit is 1/2 the price of the Active Autowerke kit...

 

I run the snow performance one in mine and I gained about 15Whp out of it. Good luck in trying to mount the water bottle!! I had a custom box made up for mine and you can't even see it. If you go down the road of NOS in general in Australia, be prepared to part with your car very quickly if you get caught. It is illegal over here, unless you only track the car. Just thought i would point it out. I never installed the kit but I am, at the moment, in the middle of altering it abit. Excellent system, you dial in when you want it to start, I have mine set to 8psi and you put in your max Boost. So you will need to know what boost you are running. I am putting a switch inside the car somewhere so I can turn it on and off. I am also going to put and LED in the car when I know the pump is activated. It is a good safety precaution as well!!

 

I have both!! The Snow Performance variable w/m and a Nitrous system!! the w/m is AFTER the I/C in the down stream horn.. and works great.. I picked up 11-12 HP at the wheels on a 35% mix. And it does add piece of mind. I also have a NOS system plumed into the air horn just befor the i/c. I was going to run both .. trying to keep the expense down and the HP/TQ up!! It is a dry shot. 23 jet. Befor I installed my PORTED HEAD, the a/f curve was good for some spray... after the HEAD instal , I , of course , leaned out a bit.. so now I will wait for my tune to fatten up the a/f.. or go to a wet system.. Trying to do this all on stock ecu has come to the end of my plans for certain mods vs the dollar!! IF my proposed TUNER doesnt hurry I will go to a wet system!! I am after the HP on less Dollars, as I said.. but I will try to be as safe as possible at the same time...yes??

Just me............................

Both cool and both increase the fuel octane levels BUT at different degrees and thus its usability. I'm no expert but have been spying threads for some time now on the subject. From what I have gathered is that W/M can be used in all gears but that NOS can only be used in the upper gears 3,4,5,.... do to the power it produces.

MISFITOY has both but indicated that he only uses NOS in the upper gears because the power cannot be translated in the lower gears to the ground.
Clearly the nozzle size has a role here so it would be good for Thumper to jump in and share his experience.

Bear in mind that W/M is cooling and adding HP but under the 20 HP levels while NOS is adding at least twice the HP levels in not more of W/M.

 

Anyone ever try using the Boost Juice or Nitro Booster with an intercooler sprayer?

 

meth is flammable

 

Hey Thumper why you putting the fuel jet .023 in the nitrous side

 

Thumper: The hp increases you were able to get, was this with the water/meth injection without a tune?

 

Why not use Co2 in place of the NOS?

I have a nice Co2 tank I was thinking about making a IC cooler with it. I talked about it with my dad and he seems to think the sudden change in the IC temp could cause it to crack. I didn't think it got hot enough to do that but what do you guys think?

I could put the tank in the rear, run the lines to a soloniod and then to a sprayer on the IC.

 

The C02 might cause the engine to stall if the intake was able to suck some up especially with an open air element.

 

I've been using nitrous to cool my intercooler and have had no cracking issues.

 

Love your set up

 

I run my own design direct port water/? system RPM and/or pressure regulated. Also the pump is voltage regulated. I use an OEM MINI right hand drive wiper tank that fits in the stock position. It is a little small in capacity but made the solution of where to mount a tank.

Cartar452...very COOL set up

NOS can be used in a single gear or all gears depending on how you set up the system. Right Paul Webster

 

so is gasoline . are you saying don't spray meth on a hot engine ? if so you may have a valid point .

 

that's a pretty engine bay

 

What mix of water meth do you run?
Any problems running staight meth?

 

D-man... I ran a 25% mix befor my Head install.. got 11 WHP ( LOL... US WHP!! LOL) With the Head and no tune I am a little on the lean A/F , so I am up to a 50/50 mix. Get on the net and search 'Snow Performance'.. they will help on the explanation on the amount of Meth vs the amount of water!! cool?? My self I have NOT run straight meth!! the next time I on the dyno ( hooking up a wet NOS system) I'll see what my a/f is and HP gains.. cool??Just me..........................Thumper

 

Just throwing my 2 cents in here. If you have a pinging issue, the water/meth will help mitigate the pinging and bring some HP back. As a general rule of thumb, 10 degrees F will be 1% of engine HP. A dyno run I did seemed to match this, the meth gives me about a 30-35 degree drop in IAT, with a 6hp increase( at a 232whp dyno, raised it to 238) at the time. This was on a proper tune that had no pinging or timing pull at WOT. If you have pinging your gains can be more. This was using a simple progressive boost controller, I am installing a controller to look at IAT, RPM and boost shortly. Not sure if it will make a difference(probably not), but you don't know until you try.

 

FACT:

[SIZE=4]"Water Injection is most efficient with a 50/50 water alcohol (or methanol) mixture.
Methanol, as an additive, is not a practical choice as it is prone to pre-ignition in higher than 50/50 percentages"[/SIZE]


Do your self a favor and do the research. And not Snow perfomance. They like many market parts and kits and are not water/water/meth or alchol experts.

Try a company that has built systems and racing engines for years. This is rocket science ya know and there are exact formulas to follow. Not guess work. It ain't cheap to do it right either. Its the old saying "speed costs how fast do you want to go"

pm me I will givew you the name of the company.

 

Why keep a secret with the company. I've yet to find a company that I'm happy with considering their knowledge and product offerings. I'd like to know who's good.

 

Exactly. Why would this be a super secret??? I too, am interested in water/meth injection as I'm sure are a few people on the boards. Give it up Nitrominis!!!

 

Ok - Some of the systems that you guys posted are very cool and very nicely installed. Most of you have given it some good thought before investing in the systems you are using. I am by no means an expert and have used systems dating back to Marvin Miller. ( Ancient ) However, I see possibly some mistakes that I have made with my early attemps with these systems. This company is notably one of the best in the world for these systems. Check them out - call them up - see for yourself. But da' aint cheap!!
Be open mined and read all the information they have. I hope this helps answer some of your questions and maybe improve on the systems you already have.

lots of good info in there! I will post up my dyno graphs once I hit the rollers. cant wait to put mine in.

 

I have found their site in the past, I must say the calculator seems to be spot on and the hardware is very nice. I do wonder as to the "suitability" of the system on the street. They seem to have a very nice hardcore system, and don't get me wrong, I like to have the best. I am still experimenting with what I have and have to wonder if the boost switch control scheme is the best based on variable load and variable IAT on the street. I'd really like to try something based on IDC and IAT, but there's not a lot of good options out there.

Anyway, I'm just throwing my opinions out, as I said, I haven't found anyone that makes everything I want.
