Alky horror stories???
Abner -- I know you don't like the SMC pump, but what are your thoughts on just running a larger pump? I have not run the setup on the bench (yet), but my guess is that for most uses, if properly installed, all of the pumps will last for years. I plan to run some tests on the various pumps to determine failure points

...SMC is selling a water/alcohol injection system, not customer service.
1 - substandard product/excellent customer service
or
2- top notch product/decent customer service
i pick #2
selling such a failure prone system w/o offering a failsafe - is not right
hope you all that are sway by the "excellent customer service", when your motor blows up - your customer service will help you with a new motor

Chris, you want to run a sturdier pump, not a bigger one - a pump made for water/methanol injection, not one for an RV to move water around.

I will be doing some testing in August, which pumps would you recommend I test and which would you recommend I use with my setup ? Thanks
Totally agree if that is the case (substandard product). I do agree the lack of a failsafe is not good, but I am using the Zeitronix and WG solenoid, so that should be more than enough. Steve (SMC) is very helpful with setup & tuning advice and offers rebuilds / mods at little to no cost (e.g. I had Steve modify my controller with remote lights so my setup could be totally stealth and he is willing to check/ replace the seals whenever one wants.)

2 out of the 3 pumps are ticking time bombs
I went with Snow because I heard of so many issues with SMC. Pumps going bad, controllers going bad, yada. I know 3 people directly with SMC kits... all had problems and had to get new parts for them within the first 6 months. That freaked me out enough not to get one.
It is interesting because Buschur has been selling / using / and recommending SMC kits for several years. I read the pump details and it seems to have good seals for ALK, is self priming, and is compact -- so I don't understand why it would be considered a problem waiting to happen. Thoughts?
This was covered in another thread. https://www.evolutionm.net/forums/sh...4&postcount=62
If anyone still doubts the integrity of the modified flojet pump SMC uses, there are plenty of other nice alky inj systems out there to choose from. Simple as that. Run a proper failsafe and you should have nothing to worry about. Now with that said, should any part of your SMC kit fail(while running a failsafe mind you
), just know that SMC will take care of you in a timely manner most likely free of charge.
Geez Guys- Ease up!
The Flojet pump goes through some serious mods before it gets put on an SMC kit. The stock pump can't handle 100 psi. We totally rework the pump covers and seals to increase their sealing ability. I like to run the kits at 115 psi max, but we test at up to 140 psi. We didn't go with the Shurflo because they are HUGE, HEAVY and much harder to mount, and they draw double the current that the Flojet does. The santoprene diaphraghm and EPDM seals in the Flojet are fine for the alky. Just like modding a car it's amazing what can be done with a little re-engineering or blueprinting.
If you check specs on the Shurflo you'll see that they are not rated for near the pressures they are being run at either...I'd prefer to have an all stainless, compact 150 psi pump, but then the kits would be $1,000 since a pump like that costs $500 IF you can find it.
Thanks for listening- Have a great Christmas!

you seriously think that its so easy to switch out some parts and call it good and its ready to run injection pressures in excess of 100psig on a pump made for non-critical applications @35psig MAX? It is not that simple..
when you raise the operating pressure of the pump, the following happens:
-current draw increases, heat generated by the windings increases - heat kills the pump - pump was DESIGNED to run 35psig max and the heat generated from a 35psig pump.
-seals leak
-diaphgram will tear
if you yourself think its ok, do not convince others its ok, it is not and its messed up to think that its ok to run a ****ty alky system and run a failsafe.

Slow car I think you know your stuff, but has anyone measured the amp draw running at 100 or 115psi vs the FLA on pump motor? I would guess that you are right just because tripling the pressure has to pull more amps, but we would have to see to be sure. I'll do a little research too.
