    Default Innercooler before or after throttle body?

    On a twin turbo setup, would you run the innercooler before or after the throttle body. Assume to be running a Fast setup, with port injection.

    Assuming you mean the intercooler, and assuming it's a TB that has the air temp sensor integrated into it, you will want it AFTER the intercooler. There's really no reason to have it ahead of it anyway.

    Default Intercooling

    Intercooler, sorry my spellin not always goood. Just looking at what I want to accomplish, it would be easier to mount the thottle body before the intercooler, but did not think that's the proper way to go. Just checking from the experts.

    I wanted to keep the system compact so i cut a edelbrock street ram in half,welded a plate to the top of it,then made a box to hold the intercooler with a mounting flange for the t/b on top of it.Their is 2 1000 hp spearco i/c's in their.Fuel dist is awesume.I can slide the coolers out the front for inspection and cleaning.My iac,map and iat are mounted just below the cooler.It's been working great for 4 years now.Good luck with your build.
