How To: Cheap TB heat shield for 3800's

I was bored and going thru my parts bin when i came up with this.

I had the Radiator fan heat shield left over from when it had to come off for the header install and had my L67 TB laying around and saw the bolt hole for the support bracket that most do not use anyway... with one simple bend i was able to mount the radiator heat shield to the TB. Yes I know people are going to say heat shields don't do much at all for performance. But, it can help lower the temp of the TB due to the header cross over and may save or lengthen the life of the MAF sensor. either way its basically a free mod. most run the radiator fans without these heat shields when having headers anyway and don't have any fan issues. ok on to the pics.

While that's cool and all... what happens at the first stoplight, heatsoak.

easy solution... dont stop at traffic lights!!!

i know engine bay temps go up when stopped, but this will be better then just having the radiant heat without it.

also GAIN vs COST is pretty good cause its free. I know over the years i have told people its not worth buying a TB heat shield, but it is free and cant hurt.

It sure as hell can hurt. If you work on the car...you will get hurt from that. Trust me. lol

Heat shield or heat collector... ? I've always wondered... lol

Great idea, but I don't think it will help all that much, what's needed is something that can DISSIPATE heat. Considering these parts are all Aluminium cast products and heat pretty readily, I would guess that the piece of metal attached to it does not contain enough surface area to dissipate heat to any effect.

Air to Air cooling requires a very large surface area with lots of fins, etc., to accomplish this. Great idea, but needs some work...


Just my $.02
