Aquamist (water) at the drags in ~45F weather

[Mark P]

Here were the 3 drag runs that I was able to log from last weekend.

I don't think this is enough data to make any conclusions, but it should add to previous data and future data to hopefully show a better picture.

Naturally, the results at 45F are not where one would expect to yield big gains, but nonetheless it's data, and I'm doing my job to share such info...

Aquamist keeps the IAT's cool (ambient was only 45F. This is much more dramatic in the summer):


Cooler IAT's allows better timing advance:


Aquamist run is just slightly faster:

To ignore the effects of the launch, I compared the speed differential between the 1/8th and 1/4th mile points and how long it took to accelerate through that differential.

The first aquamist run was 26.71mph in 4.278 seconds, for an average of 6.244mph/sec.

The second non-aquamist run was 26.21mph in 4.300 seconds, for an average of 6.095mph/sec.

The third aquamist run was 26.68mph in 4.273 seconds, for an average of 6.244mph/sec.

The aquamist runs yielded 2.44% more acceleration than the non-aquamist run, which at about a 450hp power level, equals about an 11hp difference.

Simple physic. Could it be a tiny difference, a small or big one, that needs to be verified. With a good injection ratio however, you will always yield better because of lower AIT. If someone don't agree with this, remove your intercoolers, put your intake cone filter w/o an airbox directly on the side of the exhaust manifolds and block the vents in front... simple physics.

There is absolutely NO POINT in discussing this.

Aquamist is a proven solution at the margin, not that it gives a tremendous advantage, but it does reflect in numbers. It's been documented and tested many times, including myself.

I've looged IATs in 60F temps while driving and they're usually around 30-40C. Granted, that's while the car is moving but it takes a fair amount of time in stop-and-go to climb.
