This is assuming that everyone maintains their nozzle, i.e. cleaning out the 120 mesh screen and spring loaded assembly periodically............

By closing an inline solenoid valve between WG/boost controller, on a stock steup, will cause the boost to build to max, not reduce it. Its essentially the same as pulling off the hose to the WG.

Better setup will be placing the boost defeating solenoid on turbo outlet, and then teeing the line to the WG/boost controller line.

That's not true. It will reduce the boost to around 12psi which is the spring pressure of a stock actuator.

try it out yourself, either pinch off the WG/boost controller line or yank off the WG/boost controller line, you will hit >30psig.

EDIT: nevermind

I'm afraid you're wrong on that one. If you disconnect the vacuum hoses your wastegate will not open at 12 psi.

My bad. You guys are right. I just tried it and let off at 20psi.

Not sure how this smc safeguard will work now...

I also have nothing but great things to say about SMC. I use to have a coolingmist set-up (not very good) SO I decided to give SMC a try. Best thing I have done so far.

Put the N/C (normally closed) solenoid valve on the high pressure side (eg turbo nipple). When the system detects a "fault", system will open the valve and dumps all the pressure to the wastegate - car will not be boosting more then ~12psi.

Mike, what issues did you have with your coolingmist setup?

Pump exploded, not fun. I had a full tank of methanol in there and well... it ended up in my spare tire well. The smell was horrible and it took a few weeks for the smell to go away. Every time I drove the car I got a little high. I ended up using Castrol super clean to wipe the trunk with and all is good now.

The main problem with the coolingmist kit is their pump and the boost switch (plastic POS).

Go with the SMC kit the first time. Like I have said the ease of installation and the overall quality of the kit is extremely hard to beat.

SMC certaily builds a good product. About our pumps. We use shurflo pumps in our kits. I dont know the exact problem you had with the pump but our pumps are proven to be the best in the business. Most US methanol/water injeciton companies use SHURFLO, the pump has been proven time and time again. We see very few warranty returns on the pumps as they are very reliable. I know this doesnt help you with your issue, but its not a typical situation.

Our plastic pressure switches are on our regular injection kits. for $199 to $299 thats all someone can expect. Our controller kits eliminate the need for the pressure switch and is housed in machined aluminum. When you install a controller based kit the installation is much easier than the boost switch based kits. Our controller kit for example has only 4 wires to install, Main power, main ground, pump + and pump -. When you have a boost switch system you have a 5 pin relay and a 2 pin boost switch that all needs wired its more involved.

Again, sorry about the problem you had. I have never heard a bad thing about SMC, so I am sure you will be happy with the product. Just remember that components can fail on any methanol injection kit from any company.

Wow, vendors aren't bashing each other, all i can say is i'm impressed with this kind of attitude as opposed to some other threads that were up on this site recently. Kudos to you gentlemen, keep up the good work.

I was using your kit before the release of the new control unit. I had 2.5 gal of meth sitting in my trunk for about a hour till i could find a shop vac. The car aired out for abot a day and had to use the little pine trees to get the smell out. I waited about 2 weeks before I felt safe to smoke in my car again.

I am not bashing your product, it worked pretty good when it was all installed with a few minor mishaps along the way. The thing I didn't like was there was enough wiring to choke a horse under the hood and it was quite hard to find a suitable mounting location for the tank and pump. Other than the pump giving out the unit worked great. The reason I decided to go with the SMC is the fact that the wiring and installation was fast and simple and could be done in well under 2hr. I am glad that you responded to this thread since I feel that I owe you some type of explanation.

I have had a lot of parts on my car through trial and error. I found a good combination that works and works well for right now. You seem to have the only kit I know of right jnnow for an NA car which I might need in the near future so I will for sure keep you in mind.

I will have a video shortly of the snow performance kit in action including how the failsafe works in several different situations (ie, pump failure, run out of fluid, etc)
