Throttle Body, Coolant Bypass

[Les Hall]

I have noticed alot of you guys have the coolent bypass listed in your mods, I did a search but didn't find much on it, I assume what everyone is talking about is re-routing the coolant line that runs through the throttle body,,Im guessing this is to help with cooler air intake, what I was wandering is : Is this worth doing on a stock engine? (CIA, Hypertech programmer,,Magnaflow Muffler) and will this be ok to run durring the winter months? I also wanna get a 160 or 180 Thermostat,, will I see any difference with a stock setup?

How cold does winter get where you're at?

 

Personally, I've considered doing the bypass in the summer, but GM put that coolant line there for a reason.

 

IMO, just leave it. One less thing to worry about.

it wouldnt make a difference to be there or not to be there durning the winter, its ONLY purpose it to cool the TB with coolant passing through it, which it actually heats the bitch up. so just remove it and you will be fine, no freezing up ar TB getting hot

Put it this way, I have been using the LS2 Corvette TB for 3 years and there is no provision to have coolant flow through it.

my 2008 GM OE 90mm TB has no provision for that...GM figured that it was not needed

I was under the impression that it was designed to keep the TB warm/hot in the winter so that the throttle blade wouldn't ice over.

 

I know that it keeps the TB hot as hell, and I know I'm not in a cold enough climate to worry about the TB freezing up, but I'm still going to leave it alone.

pull off the 2 coolant lines off of the bottom of the tb and splice them together. Pretty much a waste of time IMO, but I guess every 1/2hp counts and this takes no time at all, and is super cheap, so if your bored, knock yourself out

if you really think about it you really dont gain any horsepower rather in return you dont loose any HP/TQ when your engine starts to heat up thus getting your TB hot for hotter IAT

[mike1booth]

what did you guys use to splice the lines?
