Well you may know that I have a 2 ltr turbo - and with some recent events I have noticed the car suffering from heat soak, this reduces the car performance.
I could not justify the cost of larger inter-cooler as you talking best part of £1,000 and I would be an gunie pig - as not many people have done such work to an N20 in an E89.
Injecting Meth into the charger - I thought would be pushing the car beyond its capabilities.
So when I was at the rolling road, I was disusing with the engineers - and said that the WRX guys user water spray and spray onto the inter-cooler to reduce heat soak.
So I started the venture of of implementing an independent water spray kit.
Cage for water
Water Jets
Water Tanks
Primary Switch in glove box
Operator Switch
Results
Well weather need to improve but I post testing
The plan is to use meth or screen wash with atlest 30% ethanol as this has a lower evaporation level than water - so it is able to disburse heat better than water on its own
