Razor,
>>See if your intake air temps go to 170+ degrees..its very hot and will ping with whatever gas you use. Hence why I can run those air temps..cuase the alky cools the charge down big time...in this particular case alcohol works better than racegas...<<
Thats what I find on my car... ie, once the car is well warmed up, I find the temperatures at my IAT sensor is usually around 100 degrees F over ambient, since I have no intercooler. After I spray my water/alky mixture, the IAT usually drops to somewhere around 125 - 135 degrees, which isnt as cool as if I had an intercooler, but nevertheless is a far sight better than if i had nothing.
