*** UPDATE*** 26Dec 2005
SMC company claims that the flojet pump fitted on the SMC alcohol/water kit are custom modified to handle the necessary demand pressure despite the rating of the pump labeling.

-------------------------------------------------------------------------------------------------

It caught my attention that the rating of the SMC kit pump says 35PSI(2.4 bars).
My system puts over 100PSI at the nozzle, I verified this by placing the pressure gauge one inch from the nozzle and inline with the alcohol steel line.

Anyway, being the pump rating at 35PSI don't you guys think that pushing 100PSI is a bit overloading on the pump?

If I am not mistaking the pump is adjustable via spring that adjust the contators and current flow in top of the pump..

Any comments?

Thanks!!

 

35psi is where the pressure switch is activated ontop of the pump. I think you are being mislead.

 

Carlos,

I would call SMC directly and ask them what they think afterall they should know about the pump they put in the kit.
PJ......

Ps: get this someone jacked the badging off our mrs trunk last nite and scratched the hell out of the trunk

 

Yea it should be around 100 psi for it to be working properly.

 

I suggest to get it from the horses mouth, call Flojet to see if it is acceptable to exceed the stipulated rating by 3 orders of magnitude.............. My 0.2 cents

 

thats blows....is the paint work damaged???

 

Pj, sorry to hear that man. I think your MR badge and my MR badge are complety different, my badge is rectangular and says MR edition, yours is all letter and says evolution MR (MR in red I think).

I just can't believe someone did that to your car already. The lettering are about $18. I am really sorry to hear that. I have a spare lancer evolution badging, it is silver/chrome, just let me know, you can have it.

The pump has an overload protection, the motor has a thermal-cut out switch so protects the pump but not sure at what temperature it cuts in.

The pump is listed as an intermittant duty cycle - but no other information regarding the load/temperature rise over time - the shurflo has published such a chart on their specification sheet.

I think most application is intermittant - I can't see you can be on boost more than 10 seconds at a time.

I think you should take a CLOSE look at the inscription on the pump label:

Flojet
Demand spray pump
LF122202
SN:XXXXXXXX
12VDC
4.0Amps
Flow:1.0gpm(3.8lpm)
Pressure: 35psi(2.4bar)

"The LF122202 pump with santoprene diaphragm and EPDM check-valve is designed to run water at a maximum pressure of 35psi. Tampering with the pump to run 100psi will result in pump failuer due to cracking of the pumphead....." Flojet - Engineering Support, (949) 859 4945.

I really hope you got a plan "B"

 

Holy Jeebus Batman!!!!!!!!

 

Why can't you be on boost for more than 10 seconds?

 

I was referring to driving the car on the public road with traffics - or drag racing.

I have not consider the situation on track racing and rallys. My bad assumption.

 

That sucks, dude, but like I tell everyone, Please Keep EVOs (or any other nice/desirable) car in a garage. I'm not trying to hate and if you have a garage and the debadging happened away from home, disreguard me post.


Now to the thread, if the Flojet people say whats above, then I hope/think that SMC modified the pump to handle it. If not, I don't know why SMC would make a kit will a pump unable to handle the PSI.

 

The LF122202 pump was never meant to be used for alky injection. The polypropylene pumphead was designed to be used to pump water in boat and RV applications.

The only modification i can see to make the pumphead take 3 times the designed operating pressure is MAYBE going to a fiberglass filled/reinforced polypropylene resin...........
