I have a MPI supercharged Apex and the throttle bodies pop off under boost at times. Any one have any quick tips on how to keep them on the head? different clamps or couplers? Your help is much appreciated

A friend had this happening on his boosted Apex. He cleaned everything really well with alcohol (degrease)and then sprayed hairspray on and slid them back together. When the hairspray dried it acted as an adhesive and prevented it from blowing the throttle body off.

I've also seen guys weld tabs on and use springs to keep everything in place much like a two stroke exhaust system.

You can try gluing them on with a product called "The right Stuff" I think it might be made by Permatex but the best solution is mechanical one. I welded brackets on my intercooler then bolted it all together.

I blew the throttle bodies off my apex on the first test ride after installing the super charger. I took it back apart, re-cleaned everything with 3M brake clean and then used 3M spray glue putting them back together. No more issues. Eric
