Throttle Body Bypass?
I'm about to undertake a few HP mods. Looking at tb bypass. It doesn't make sense to me. Even if you disconnect the coolant hose isn't the heat of the engine block going to be transferred directly to the throttle body? In fact the coolant connection may actually reduce the heat at the tb. The engine block is hot metal and it's heat will be directly transferred to the throttle body. What am I missing here?

Re: Throttle Body Bypass? (94 Red Roadster)
what your missing! is about 5 hp if you DON,T do the MOD, WHY it works is that the air flowing thru the throttle body absorbs heat at a faster rate than the engine block can transfer it to the intake,

In the stock configuration, hot air is blown into the throttle body to prevent freezing in extremelt cold conditions. You don't want this b/c the hot air robs HP. This isn't a mod that you're going to 'feel' the difference, but hey 5 hp and it takes a half hour to do, and cost me .50 for two hose clamps :chevy

Some heat will conduct up to the intake and plenum of course, but it wont be so hot that you cant touch it, and it is if you leave the coolant routed thru the TB. Coolant would actually act as a heat source to directly send engine heat to the TB, which heats up the intake air.

:withstupid: I guess I didn't realize that people actually cut that piece off. I thought people just plugged the hoses.

Re: Throttle Body Bypass? (94 Red Roadster)
The LT1 has strategically placed steam vents at the back of both cylinder heads. Since the heads are the hottest part of the engine, pockets of steam can be more easily generated there. The steam vents are connected together by a crossover vent tube at the back of the heads, which directs any steam and a small flow of coolant to the front of the engine where it flows through the throttle body, warming it for improved cold weather performance. After passing through the throttle body, most of the steam is condensed back into liquid coolant and returned to the system.

Okay, what exactly did you guys plug the TB tube openings with after you connected the hoses? :confused:

Re: Throttle Body Bypass? (Beautiful Beast)
Beast, I have a question about your mods (sig). You have a 52mm tb which most have integrated airfoil in the design. You mention airfoil with the MAF... do you have an airfoil infront of the MAF? That would seem to make sense as mod-- to shape and concentrate the airflow over the MAF wires. I was just wondering.

Re: Throttle Body Bypass? (Lone Ranger)
great mod for 5 hp or so.u can feel your tb after an hour of town drivin and it wont' be hot! when i took my tb off i brought it in to kragen and matched up the ends with rubber block offs.only about 2 bucks for a pack of.....2! check it out,dont' leave em open for elements to be wandering in the tb.might not hurt it ,but ,just to be safe block em off.do that and other free mods pic up a tenth or two and be happy.
