Throttle body bypass
#11
#13
I did a throttle body bypass on my '94 Camaro Z28 over two years ago. The first comment I have is that I did not notice an increase in performance in any way whatsoever. In other words, don't expect to be breaking any new records after this mod. Take everything else I have to say at your own risk - just in case you become the first person to actually get your throttle body to freeze open.
I went through a few winters in Colorado where the temperature went below zero deg F and I did not have any issues. This includes sustained driving for about fours hours in below freezing temps at higher speeds. Before I did this modification, I did an internet search to find someone who actually had their throttle body freeze after doing the bypass. I could not find a single occurrence of this (I have not looked since then). Perhaps it is possible under certain conditions that I have not encountered, but I am skeptical. Or, maybe no one has posted after doing it because they didn't survive the crash. So if I don't post again after the next winter, it might be because I was wrong.
Good Luck.

I doubt that unless you have water comming into the intake air stream you would not be any chance of the throttle sticking open due to ice. Another thing is the engine bay would have to not heat up any of the incomming air and we all know the engine bay in these cars gets good and hot no matter what. GM put the coolant pass through there to heat up the incomming air to help with fuel atomization, since warmer air will accept fuel easier. IT was just to help emissions out a little. Gaining 6hp? really? I doubt anyone has they as$dyno calibrated that good. A machine may be able to tell, you will not.

oh and those iPhone dynos... Yea one told me the airplane I was in only had 450HP when we were taking off. (I think it missed the mark just a little) and my arm had over 1000 (again another miss)

I guess if you did full exhaust gaining 25 then cai for 10 t- body for 5 tune for 15 and doing the bypass for 6 and making a grand total of 61 hp does sound better than splay doing a bypass for 6 lol I guess if starting out with 245 rwhp and adding 6 to get 251 doesn't compare to 306 rwhp. Not a mod to brag about but does add up nonetheless
