I am going to explain my objectives, and share my thoughts on the setup, based on my current understanding of the tech.
Any corrections, advice or general feedback would be much appreciated.
08 Elise SC with factory non-inetercooled MP45 supercharger. Factory maps. 93 octane(US) gas.
My only objective is cooling on the track.
Want to keep factory maps. Not looking for more boost.
Need to run 30-45 min track sessions, ideally
using washer tank.
I place high premium on simplicity and easy setup.
My understanding is that for cooling - 100% water is ideal. Except, I don't want to loose octane rating compared to the gas in the tank.
What would be lowest ratio for that purpose? My guestimate is 25% meth?
Variable vs constant spray
Seems to me that on the track I should be good with "off/fully on" setup.
To save on juice consumption I should benefit from a load-dependent activation trigger.
I am thinking 50% throttle or some proxy. The downside is additional setup complexity.
For the same reason it would be good to have a power switch, so I can keep it off for the first 8 or so min of the session, until the SC heats up.
At 25%(?) meth what should be the minimum flow to stay cool enough to prevent power loss?
I am guessing 100cc/min?
Snow Performace Stage 1 seems to address many of my requirements, except I didn't really understand how their boost switch works.
Didn't quite understand AEM and CollingMist products. They look very sophisticated but I am not sure that sophistication is of benefit to me.
Anything else I am missing?
P.S. I am planning to spray before the SC.
