So, with the VT2 you are thinking of a fan on the front air/water exchanger for stop and go type traffic? I assume it gets plenty of airflow at speed....the only real issue here (ESS has tuned it to be safe in just about any environment) is while sitting in traffic (or the track grid queue) you will get hot air at the AIT sensor which causes ECU to pull timing which loses power significantly. A fan might prevent that?
I have purchased but not yet installed a VT1, which is why I am planning water injection. The calculations for the V10 at 5 psi and 8500 RPM result in a point way to the right hand side of the compressor map (V3Si), making almost as much heat as airflow. The S85 almost needs a bigger blower, except the next step up in the Vortech catalog (v7 Ysi) looks like a serious packaging problem in the engine bay. Or two blowers like G-spot, which would then price it out of the enthusiast market. So, long story short, without an intercooler I expect some timing-related (safety-related) power loss at high ambient temps during multiple high RPM full throttle runs, which a very mild water injection system might
prevent. I hope.
THanks for reading, and again if you know I am spouting crap please call me on it as I am still in the research/learning phase.
Tuning for additional power using 100% meth in large quantities is a whole other game, more like nitrous oxide than anything else.
