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.

Now how bad will your car beat a Z06? This one looks like it has a tune.

WOW!! May need a VT1 just to keep up with a stock F10.... boy that is impressive!

Before the F10 came out, I was thinking the Dinan stroker would be the benchmark for it...and so far that seems about right...so the VT-1 kit will probably be very close...but perhaps slightly slower. That F10 looks very easily tunable...so might as well just go with the VT-2 kit just to be safe...because I think we're gonna have a lot of 650-700chp F10's running around soon....

That F10 is fast from just out the box, who knows what it is capable of with some tuning

Have no decided if the fan will be on ony when at a standtill, maybe it will be activated via a switch in the car. The general idea is to cool the air prior to the heat exchange but we shall see.

I think you meant G-Power as G-spot... well lets not go there

.
I would get the heat exchanger unless your adament on just using meth to do the same thing.

I am actually amazed at how fast the F10 is. My M6 isn't fast at all at the moment. Got off work to head out of town to the track and the car went into limp mode on the on ramp. YAYYYY!!! Throttle actuator on bank 2 is out and will take a day to get here, FML!!

Lets talk about the G Spot that will cheer me up, haha.
