    Swapping MP 112 for 76mm?

    I am tired of constantly fighting the IATs on my Maggie...it feels like after a couple pulls I don't even have a supercharger on and the IATs are around 200-210* so I am thinking of selling it and buying Trick Performance's Stg3 turbo setup. What are your thoughts? I've always wanted to try and go turbo, but never wanted to piece it all together. It seems like Trick's kit is pretty straight forward (of course minus fuel and tuning).

    Had the same problem with a vett we were working on. my tuner refused to tune it because the iats were so high.

    I figured that would be the consensus...

    French, yes they are intercooled, but not enough!! These things are like a waffle iron on top of the block!!

    No Meth? Seems crazy to me that it could be that bad, but hey turbo's are awesome too.

    Meth would be too complex to work efficiently, I would have to modify the manifold. If I ran it through the SC it would just heat up as well...

    That is a great decision. You will make more power and most of the kit can be paid for with selling the Maggie and other parts you will no longer need. Like headers exhaust. Etc.

    Simply the best turbo kit for late model GM trucks.

    Custom fabrication to fit your budget and needs.

    His kits are a great value. No need to cut a deal his kits are already priced very nicely.
