Cooler weather alky tuning

[blackgn1]

At what point does alcohol need to be turned down? What inlet temps become a distribution problem? I spray alot of alcohol(dual nozzel). We are going to start seeing some cooler temps here and Reynolds even cooler I'm sure. Bowling Greens cold temps didn't seem to cause anyone any problems but with so many guys running FAST they have a little more wiggle room. I know this subject has been touched on several times. The difference in setup's would play a role in this also. I run a front mount intercooler which is giving me cooler air than someone running a stock location.

This may be of little use to you since I am running an on center GN1 intake but I have not had any issue with distribution. My IAT, measured in the plenum, is 60*F and up during a run. I run 2 nozzles and I also run a front mount intercooler. The intercooler I run is a little small for my application (CAS V2) but that little bit of extra heat compared to a bigger front mount may be why my combo is working well.

Thanks Robert. Your information is valuable. I think even your style intake would push the alcohol toward the rear cylinders. I going to do some tuning the next few weeks and have never pushed the car in cooler temps.
