wmi intallation

[owen lcr]

just in the process of fitting my water methanol kit to my car today and i am about 50% through the fitment.

I am not at the stage of tapping the nozzle into the pipework, and just want some verification before i go for it.

Going to install the nozzle after the intercooler but just before the AIT sensor (about 8" before TB), just want to make sure that this wont affect the operation of the Divert valve as it is piped between the AIT sensor and throttle body.

Got a quick drawing to try and make it easier to understand than my crap explination

I'd mount the nozzle as close to the intercooler exit as possible. That'll give you the best chance of all the methanol evaporating before it passes the valve. Also the charge will be cooled by the time it reaches the AIT, rather than getting a 'false' reading because the charge in the inlet mani is cooler than the charge at the AIT.

I had some evidence of methanol on my 007 divert valve - and that was through vac lines.

right ok, only problem is that the pipework from the intercooler is Silicon so cant really mount the nozzle into that, and there is only about 4-6" of hard pipework prior to the AIT sensor then a further 4" to the DV and then about another 3" to the TB

You thought about a Self sealing bung On the silicone pipework?

 

[owen lcr]

not really mate, i could do that but not sure how effective and robust they are???

You can get a plastic adaptor that goes into the wall of a silicon pipe. They work well.

looks good but next problem is i have a twintercooler so would i mount it on the forge cooler, oem cooler pipework or where the 2 peices of pipework meet/join

I'd mount it where/after they join so you're cooling both charges. Otherwise you'll get warm air from one heating air that's cooling from the other.

ok, sounds like a plan mate...

from all the places ive spoke to about the position of the nozzle, they have all said no closer to the throttle body than 8", and ideally closer towards the IC than the TB.

they said to beware of going to close to the intercooler connection as there will be turbulent air coming around the bend which could cause droplets, so id say in the top of the bottom third of the pipe

ok mate, my car is out at my old mans at the moment on the ramp so will get cracking on it tomorrow morning, the only thing i an worried about with those silicone mounts is that it may get in the way of the spray pattern? thin i am just going to try it in the very first part of the hard pipe!

this is still about 14" away from the TB but only 4" away from the AIT sensor...

 

[vRSy]

i reckon that would be alright, hae you took pics of the install

 

[owen lcr]

not yet, didnt have my camera so going to do it tomorrow mate

Is there any sort of soleniod valve on our engines that is used to regulate the amount of boost the waste gate sees? or is it all mechanical

i think its the spring stiffness in the waste gate that does this isnt it?? are you after a boost signal for your take off??

 

[owen lcr]

need to find I wire that can shut off boost to my turbo for the fail safe on my wmi kit. If the car does this mechanically I will just need to get a boost controller

it's n75 valve. Look at illustration 145-65 in ETKA, pn - 06f 906 283 f

 

[owen lcr]

does the MK2 cupra have an N75 valve? if it is this can someone please get this page up from ETKA for me as i dont have it

 

[Amet]

i need one more post to give a pic
