    LT4 supercharger conversion IAT location

    Just finishing up a LT4 supercharger install on a LT1 stingray. Id like to get the IAT sensor out of the MAF with a breakout harness. My though is to remove the front OEM MAP from the supercharger and use this port to install the IAT sensor. Is there a better location or way to install an IAT sensor?

    That can work...
    I welded a spot on back of passenger runner and added my iat there when I did this..

    I was the first to do the lt4 swap on an lt1 if you need help with tune

    Any additional help would be great. I’ll plan on the IAT sensor in the front MAP location, as I’m using the rear MAP location for a 3 bar sensor. I need a bit more time as I’ve decided to install the LT4 pump and injectors. Should make some decent power.

    I make a conversion harness that takes the iat from the maf, and also converts from the stock 3 wire map and uses the factory LT4 4 wire map sensor in the back of the blower with built in iat.
