throttle body bypass pros VS cons
the throttle body is supplied coolant to prevent it from freezing. in most cases, these cars dont see freezing cold weather or they are garaged during the winter.
so a lot of people will perform this "mod" to keep hot coolant away from the throttle body and keep the throttle body cool, thus cooling intake air charge.
my personal opinion, waste of time. i hate coolant. i hate getting it on my hands. this mod isnt worth ****. ive done a lot of research, your intake manifold is going to absorb heat from the block and heads, so the throttle body will absorb heat from the intake. its going to get hot either way, but it doesnt matter anyway because the air will eventually enter the intake, heads, and combustion chamber, which dont change in temp by doing this mod, so the air will still get hot.
i did it back when i was a noob, but now i realize all these little free mods are a waste of time and create unnessesary risks.

I did mine. Its very easy and I drove mine during the freezing cold a few times. never gave me any problems. It has been proven to be 4-6 RWHP by several places around me. It might not be seat of your pants power, but it all adds up.
it's not a waste of time, it is worth a little hp.
no cons really
I also fail to see how it creates an "unnecessary risk". It was designed to prevent the tb from freezing but I have never heard of a case where that happened as a result of this being done.

I did mine and it was easy and now when if I take off my t.b. I don't have coolant everywhere
I did it when I had my LT1 and when I got off of the road you could put your hand on the TB and it was cold. I don't know about it absorbing Heat, it was pretty damn cold everytime.

[snipped] my personal opinion, waste of time. i hate coolant. i hate getting it on my hands. this mod isnt worth ****. ive done a lot of research, your intake manifold is going to absorb heat from the block and heads, so the throttle body will absorb heat from the intake. its going to get hot either way, but it doesnt matter anyway because the air will eventually enter the intake, heads, and combustion chamber, which dont change in temp by doing this mod, so the air will still get hot.
maybe, just a few drops of coolant come out when removing the hoses. The whole
process took much less than 10 minutes - additionally, I got no coolant on my hands.
difference - the true worth is when you do multiple mods that make a difference.
When I come home from the office, I drop the change out of my pocket into my
"change drawer" - sure, 13 cents or 77 cents isnt much, but it adds up - last time
we counted, there was over $400 buck in the drawer.

I think the gasket helps a bit to keep the heat away from the TB. If there was no air moving from the TB into the engine, and you got the motor up to 200F with say, a system like F1 cars where they pump hot coolant through the motor (because when cold, they are essentially seized up due to such tight variances when built), that MIGHT get the TB warm. I just think that the air really helps, as well as the aluminum construction. My intake actually doesn't get very hot, however my crappy eBay CAI that is chrome steel, does. (I'm not the tard that bought it, came on the car.)
IMO I see no reason not to do it, whether it offers gains or not. I don't feel the need everytime I want to pull my TB to clean it, or to pull the intake, to have to dick around with coolant being routed through the trottle body.
As for freezing, many many LT1 b-bodies get driven in all sorts of nasty cold *** weather. I don't think I've ever seen a single mention of the TB freezing up.

to the OP if you are torn enough to make a whole thread about this mod that takes less than 5 minutes then i think you would be better off not doing it. it seems you already have your doubts and it would be worth the piece of mind to just leave it on.

It can't hurt to bypass it cause the new vettes, tahoes, subs, and trucks don't have coolant lines running through the throttle body anymore. I did it to mine long ago with no ill effects, but I live in Texas.
Just do the mod, Im doing it soon for the heck of it, I cant see any real consequences of doing it and any power helps even if you cant feel it because it all adds up.
