Coolant Bypass Mod bad for the winter
Just like that title says, is it bad? I live in VA and it will be icy cold and just don't wanna damage my car over a stupid mod. Just curious

I don't think it will be bad, just let the car warm up well on those really cold days.
I think the only ones that should be concerned are those way up north near the Canadian borders (and in Canada) and even there it is unlikely that a 'coolant bypassed' TB would ever freeze up completely IMO.

I've heard people running with a TB bypass, and they don't have a problem.

The moisture can freeze coming in the throttle bore under light throttle conditions. The blade is open slightly & a high vacuum is drawn at that point & can freeze moisture in the inlet air to the motor. Thats how you can get strange idle issues. It cannot build up enough to freeze it open, shut etc.

You could always do what the Alcohol dragster guys do on the start line. Just pop your hood and spray deicer into your intake until you reach operating temperature. I wouldn't worry about the bypass mod causing a problem. I think I 'd be more concerned with my heated side view mirrors failing on me if I had heated side view mirrors.

I've have never had any problems in the winter with my coolant bypass. I have got 160 thermostat and induction mods so if anyone would have any problems it would be me. I have also sprayed in the winter and never had any problems.

I doubt it makes any difference. I still have not figured out why they did it. The 98+ S-10 has a remarkably similar throttle body (75mm blade, with a wonderfully designed restrictor plate on it...very interesting piece of GM technology), and it has no coolant provisions at all. I think the coolant thing is a bunch of crap. The only difference I can say is that the S-10 TB is mounted on top of the engine, which would provide more heating of the TB once the engine is warm. But once an LS1 is warm you should not have icing problems anyways.

I drove the 401 in Canada many times during college
(shorter route and cheaper gas than going through
the States from Detroit to Buffalo). One trip was cold
(just above freezing) and heavy fog. Car started running
like **** and couldn't hold speed anymore. Pulled it over,
started checking **** out with a flashlight, found my
carb was plugged solid with icicles. Had to sit and let
it melt.
Super high humidity and right near / above freezing
at low throttle is the worst for icing.
