Well the weather is gettting warming and I'm thinking of doing a throttle body bypass. Have any of you guys done this? If so, did you notice any hp gain?

You might get half a horse gain with it. Your car will idle like $hit + in colder weather its a killer. If you're year round in hot climate area i guess it could be worth it.. or rather, it just wouldn't cause harm, but whether its worth it or no - is debatable.
If you want real gains in summer time go a step further and hook up throttle body intercooler system that runs off your AC freon

It wouldnt be worth the trouble vs the performace gain, maybe considering a cold air ram system, with some 3" flex ducting pipe, bring up some cold air from the front of your car to where your CAI setup . at lease you can bring down the temp of the air going in ( warmer the air temp the less effective the combustion) since your running a short CAI setup. engine compartment gets very hot in there.

Do tell. More info please. I don't think I ever heard of this before. I've heard of icing down the TB and intake manifold, but this sounds interesting.

I think you and I are talking about same concept, icing down the TB using AC freon. Or just building a separate freon system that runs off electricity and non belt driven. The problem with icing intake manifolds, they are made out of plastic nowdays. Cast iron or aluminum manifolds used to be easier to cool down than plastic ones they use now. So now your options are pretty limited to cooling down TB and intake piping itself, then your manifold will raise the temps a bit before air hits the engine.

Yup same concept, but using the ac freon system seems a lot more practical than carrying around bags of ice or dry ice with you. At the track the dry ice thing works, but a system that uses freon to cool all the time, that sounds cool (no pun intended). Ya your right on the intake manifolds now-a-days, plastic is harder to cool, I was thinking back to when I used to use dry ice on my mustangs aluminum manifold. So is there such a kit, to use freon to cool the throttle body / intake piping? Have you ever heard of anyone doing this?

I'm sure there are universal kits out there for hardcore racers. Theoretically it shouldn't be that hard to fabricate a kit but working with freon is not easy, you gotta make sure your system is sealed.

Yea if theres a leake anywhere the engine will suck it up n shut off due to the non combustable nature of the gas. I did ac work for about 3 years and freon piping is pretty tricky when it comes to making bends and joins. the slightest weakness in the pipe or any rubbing will def cause it to break and god forbid the gas shoots onto hot engine parts causing them to rapidly cool and crack. It sounds like a good plan for some added power but it needs to be planned well and executed with perfection to ensure proper function and reliability
