If you want to get rid of KR then free up the motors ability to breathe not drown it in water.
Just my thoughts.

I sent him a PM regarding this a few months ago when he was first starting to show interest in it. He replied and said that he was going to try it and see himself. And if it didn't work, oh well. Gotta respect the guy for that.

I have to agree with you guys regarding the 3.0 pulley. I popped on the 3.2 pulley tonight and OMG 
with these cool temps, sea level altitude and dry roads I couldn't keep the tach from instantly and continuously hitting 6000 rpm. 
It pulled like a rocket.
A significant difference from last night running with the 3.0".
It sure didn't take long to learn. About 15 minutes. :P
I launched it at one point over a rise at 100 mph and it shifted into 3rd as the front wheels lifted off the road and when it landed the tires went up in smoke.....at 100 mph
Good thing for the limited slip as it helped to control and keep the car going straight.
I still reserve judgement on the water/METHANOL spray. Yes if it was just plain water, I might have to agree with you guys but it'* 50% methanol and with the secret 50hp booster
boost juice that'* what adds the fuel to the air it displaces.
The real benefit will come from increasing my timing a couple of degrees.
I thought, from reading the INTENSE site that the stock injectors will work down to a 2.8".
Also remember that I have increased my fuel pressure by 4-6 psi which will also help to compensate.
