Not really my idea, the Snow Performance kit came with little LED's. I just decided to use larger ones for level and spray so I could see them from the corner of my eye. For all other LED's I recommend smaller ones and placing them out of direct sight when sitting in the drivers seat, so they don't irritate you when driving at night.

I guess I should have added a new post instead of editing the last one with 1/4 mile times. (see post
#400 )
I have noticed a slightly richer A/F mixture while spraying. I have not adjusted for it yet since I am still experimenting. I am not using boost to activate the W/M spray, I am using MAF voltage. Most W/M manufacture instructions that I read say to use MAF with Roots type superchargers, and boost for Centrifugal and turbos. I don't trust the vacuum/boost ports(vacuum transducers/sensors) on electronic devices either, they can break easily or the vacuum/boost line could break and then you have no spray. If I had a turbo or centrifugal SC I would have used the boost port though. My controller can do both.
Snow performance says you should not spray below 3,300 - 3,500 RPM or you could have combustion quench. I have read that feels like spark blow out or hitting the rev limiter. I looked at some of my datalogs to see what the MAF count number was at 3,500 RPM and choose a number slightly higher, I then converted the counts to volts and set the W/M controller to that spot to come on. I looked at my max MAF counts and set my max spray off that.
Driving around watching for the light to come on under different conditions proved that the spray doesn't come on under normal driving conditions and it does come on when under heavy acceleration so I am pleased with that setting so far.
As far as the jet/nozzle Snow has theirs rated for HP.
250 - 350 RWHP: 175ml/min nozzle.
350 - 475 RWHP: 375ml/min nozzle
475 - 600 RWHP 625ml/min nozzle
I started with the smallest one. I want to see how far I can advance the timing with that nozzle, then I will try the next size bigger. Once I find an appropriate nozzle size I will order one from another manufacturer that uses a hex shape to tighten or loosen it. The Snow nozzle uses to small flats that you can barely get a wrench on, I was not impressed with that.
If there is a worthy gain in horse power I will keep the system, I will play around with timing and A/F to see what works best. I also plan on adding the Safeinjection unit and W/M flow gauge (another $400.00 for both) for added engine safety. If there are no worthy horse power gains I will just remove the system.
I wanted to add that some W/M calculators came up with a nozzle of over 600ml (when using 1) when I typed in my specs, and I have only started with the 175ml.
There seems to be a lot of conflicting information on jet size. I think mainly because of pump pressure and flow specs.
