[QUOTE="Willie, post: 15473811, member: 14133"] As I stated in that thread, I installed multiple digital air temperature gauges. The first was on the elbow, just after the methanol nozzle. Comparing this temperature with IAT1 told me how much the methanol cooled the aircharge. As you know, the IAT1 is close to ambient, as long as there is no heat soak. Let's use numbers here so I can illustrate my example better. Let's say IAT1 is 90 degrees, which is what my gauge would show. Then as the methanol is sprayed, I could watch the gauge drop. Basically, it would drop linearly and continue to drop as long as the methanol was being sprayed. At the end of a 1/4-mile pass, it would be down to 65 to 70 degrees. So all is well, right? Not exactly.... This is the air temp going into the compressor. My second air gauge, located at the base of the blower (pre-intercooler) would read around 200 degrees, give or take. Now if I were NOT to use the methanol, this pre-intercooler air temp is basically the same, so the 25 degree drop pre-blower is completely negated by the blower compressing the air. IAT2's are unaffected. Snow's "claim" is not what I see in real life, so if you decide to go with their system, most, if not all of us, don't see a difference in IAT2's and eventually trash the idea, thinking it was a waste of money.... On a centrifugal blower, such as Vortech or ProCharger, the methanol is sprayed after the blower and is very effective in lower air temps. Not so with a screw-type like ours. So I then tried experimenting with nozzles after the intercooler. This is where I DO SEE a temperature drop in IAT2's. I know this is long so I'll stop here... There's lots more, including tuning, or the inability to find a tuner that will work with this stuff...... but trust me, if you are a die-hard methanol fan like myself, I can say there is a way.....
