Well I desided to go c16 on my motor since a) it's going to be track only and b) because I spent about 4k on it and don't want to break it I've already got the AI system setup and if there is still a good use for it then I will keep it and spray a 50/50 mix at the tb inlet with two m10 nozzles. Anyways thanks for any help yall can give.

 

I would just use water for knock protection. 1 m10 nozzle.

 

oh really? I know jrat uses c16 and alky with some good results. what would the alky do with the c16.....Should just add to the octane correct?

 

What boost are you going to run?

 

The octane is not the problem, its the effect of *net flow of fuel* and the heat it liberates that is totaly proportional to the qty of fuel the engine injests.

WI gets away from the fuel only philosophy and does a better job (depending on which side your activley pushing) with far less qty's of fluid

In regards to the question at hand YES it has application as a heat control device if not a detonation control one. i can tell you from first hand experience that the addition of WI on C16 fueled rotaries at the upper ends of the sport that use it does indeed extend the life of engines using inferior materials on items such as apex seals

If your not prepared to use fuel dumping (up to 50% excess over stoichiometric) to control temperature then WI is a viable alternative to look at regardless of fuel octane.

 

Interesting, thanks for the input rice. I'm going to have my microtech tuned around 25+ psi on a t70 and was going to go with pump gas/AI however with the motor costing around the 4 thousand dollar mark (new housings, all new seals, springs, porting etc...) I would rather not take my chances on pump gas. That being said my main reason for asking this is I'm going to want to get the egt's down as much as possible since this is a small little .96 hotside and hks log style manifold. I would emagine that back pressure is going to be a big problem at those boost levels witch I would think would push the egt's up pretty high. I'm going to be logging my egt's pre turbine so I should get a good feel for how the water/alky injection is doing for my egt's. I also have a 1.32 that I was thinking about making work with my downpipe along with my .96 so that I could change them out durring the tune to see witch one would be a) more healthy for my motor and b) witch one got me to my hp/boost goal.
