Snow Performance makes a new water/methanol injection kit for our cars that reads off the MAF. Has anybody used their products or any others for that matter?

My LT1 is n/a but really high compression after the recent rebuild. It does not like these 100 degree days at all. The dynamic CR is borderline at 8.8 +/- and I'm sure cooler temps would help but right now lots of knock without lots of xylene which is getting expensive. I'm considering this kit if it will allow me to run on 93 octane. Right now it likes about 99 octane so I'm wondering how much a water or water/menthanol injection would help.

 

Maybe rskrause will answer 'cause he has experience with the water/alcohol injection.
If he doesn't then PM him. There are others also.

If ya don't want to tear it back go here and read. They are nice to prevent damage to the engine.

 

For an NA motor I think the way it could help you is by slight high octane enrichment more than cooling. Alky is pretty high octane and the slight enrichment should help too.
I have no experiance with it but everything I have heard about that kit is good.

 

Ya could try a bigger rad and Evens coolant.
I am running 9.1(figured correctly) with 92 octane with no problems.

Maybe your tune is off.

 

I have done a bit of experimenting with water injection and NA motors. It's hard to quantify with the tools I have available, but in one test we used my '01 Silverado. It would pull quite a bit of timing on 87 octane, and the knock retard as well as a bit of audible ping was eliminated using water injection. Would it eliminate your knock?: Maybe, I can't say one way or the other.

I haven't looked at a Snow kit, they almost seem to cheap to me though. Working off the MAF is not logical to me. On an NA car, I'd activate it using a WOT and rpm switch.
