Hey SBS! I am thinking of meth for intake cooling.. need your suggestions

I think the pump is 5 lbs. I was thinking of attaching it to the plastic splash guard and then you can just drop it and do what you have to.Would have to see if it could hold that weight. You could also just zip tie it up so it doesn't push very hard on the cover.

Oil changes are gonna be a b!tch that way...

I mean the splash guard that is in front of the tire / under the washer fluid tank.
 
Yup... the log pretty much is .1 volt for each psi...

At 100kpa which is 0 psi and 0 vacuum the logs show 1.58...

At 129kpa (4psi) the volts are 2.0 on the MAP... and so on and so forth...

About .1 volts per psi...

And I am using a voltmeter and/logs to adjust the rheostats to find where I want it... yes it's a PIA...

It's not just enter a number and go...
 
One of the problems I have noticed and it's not really a problem but more a characteristic of this setup and any setup...

Our turbos spool so fast that if I tune it for 8-9 psi for the meth to spray, I won't see the effect until after that...

Sure the pump kicks on and starts spraying but by the time it turns on, builds pressure, starts spraying out the nozzle, and hits the IAT sensor I am past 9psi...

This only applies to WOT runs.. I can see it in the logs... BUT if I tune it to spray at 6psi then it helps catch up to the fast ramp of our turbos.

Duly noted.  I am still not sold on using the MAP versus a boost switch.. it goes back and forth in my head.

Either way will have the same issue.... if you use a boost reference it still has to hit a relay that activates the pump...
 
Indeed (noted),  I need to data log a drive around town,  See where the boost runs typically and set a smidge higher... OR use a on/off switch to only enable the unit when I feel like it.

 
I'm just being nit picky really... as long there is no knock and STFT are ok then "tuning" a meth kit isn't that hard :-)

I just don't want to be spraying while I am driving around like a normal human being... lol

Sort of tangent question.  If you turn it WAY up.. IE max at very low boost would it all vaporize?  or would it 'wash' the intake?

No.... it will flood the engine and you will stall out. You could end up washing the walls of the cylinders which would foul up your oil....and potentially hydrolocking your motor...

Nice!  ''ok not to do'' list ..
 
Think the McMaster sprayer will be the better option install wise, it has a head so you are able to lock nut it and then use a standard brass 90. Thats like double safety and no bulky adapter inside the intake pipe.
 
Bought these last night:
Nozzle Holder low profile: Devils Own

Check Valve: Devils Own

Still torn on which nozzles to use. Alky looks to use the mcmaster nozzles purely based on appearance.

Went with McMaster nozzle 3178K85. Its 200 ml/min.
Also bought the tank bulkhead, boost switch , and pump from snow.

Its a collection of items from different vendors but for this purpose, I think it will be the cleanest install. The only thing I'm missing is a (silicone, neoprene, buna-n) bonded washer which I need the size of the base of the nozzle to get the right size for nozzle to pipe contact.

I like the nozzel, it will be more flush to the pipe..

my thoughts exactly. I can confirm its what the Alky kit uses. Emailed them about the sealing washer as I cant seen to find one.
