2. because most people don't want to pay for the best way. People want 100 horsepower for $10. This is a step closer in that direction compared to the old South County CAI's...


1. In Normal driving the temp never goes more than about 20-30 degrees above ambient while stopped. (ambient above 80) It drops back to ambient in a matter of seconds once moving.

In a "worst case" scenario...
I waited in the staging lanes for 30 minutes and IAT was at 150+ degrees. Ambient was 85.
By 330' it was ambient +20, by half track it was ambient, by the end of the track it showed less then ambient. Yes it was (and always is ) very humid so evaporation of the air moisture from the high velocity air is why.

Also that was with my old "el-cheapo" garbage can heatshield. (basically a hot air "break")
Now I have one made from ~3/16" plexiglass and it seals completely to the inner fender.

2. I definitely agree. I was mainly pointing out that most "CAIs" are really "HAIs" without a good heatshield and adequate cool air source.

Though I do subscribe to having a straight shot into the TB from the MAF. That's why I like my setup better.
