Redfox340 Posted October 1, 2003 Report Share Posted October 1, 2003 Coolant circulates through your throttle body to avoid thermal expansion / cracking in very cold climates. The myth is that if you 'bypass' the throttle body you'll see more power. Not true; you'll feel a better throttle response but nothing on the charts. My recommendation: leave it, engineers made it for a purpose. I would find other modifications / parts that'll make more of a performance impact. - Erik Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted October 1, 2003 Report Share Posted October 1, 2003 sumone told me sumthing about a throttle body bypass, and i was wonderin if neone knew who to do that wit a 3.1 cutlass I did it on mine, very easy. Makes taking the TB off 20x easier Rob Quote Link to comment Share on other sites More sharing options...
ismellrealbad Posted October 2, 2003 Report Share Posted October 2, 2003 I did it on mine, very easy. Makes taking the TB off 20x easier i did it for that reason and you do NOT get any performance gains, however the car seems to run alot cooler on the highway. i cant tell you yet if it runs cooler for around town driving because my fans are not turning on for some reason Quote Link to comment Share on other sites More sharing options...
Nick1234 Posted October 2, 2003 Report Share Posted October 2, 2003 I was told that cooling off the tb will not give you any performance gains do to the fact that the air doesn't stay in the tb long at all to heat up that much. What could help you would to somehow cool down the plenum and intake with spacers to get it further away from the hot engine but your best bet is to just get some sort of CAI.

midstar Posted October 3, 2003 Report Share Posted October 3, 2003 I know that on aircraft they have a carb-heat function to keep you from freezing up the carb. It mainly happens when landing and you are at a low throttle setting, then you are gliding in. Could that also be a reason? Quote Link to comment Share on other sites More sharing options...
mdelorie Posted October 3, 2003 Report Share Posted October 3, 2003 Nah, TB ice isn't really an issue. It's more just to warm the air entering the engine for REALLY cold climates. The only way a CAR would get TB or carb ice is if it were operating at 8000 ft! Cars engines also rev way higher and are generally warmer to start with (being liquid cooled) And actually, carb ice is a problem on a/c anytime you're on low power settings OR if the relative humidity is high. Doesn't even need to be freezing, as the venturi in the carb is enough lower the pressure of the air to it's dewpoint. I bypassed my TB on my 3.1... but only because I blew a hose under there anyways and was just looking to keep things simple. I didn't even have to take the TB off, just pulled off the hoses, and used a 90 degree elbow to join the two other segments. I DID seem notice a BIT (hardly noticeable) more power available when the engine is cool / cold... and it takes a bit longer to warm up. Unfortunately, I had my induction system off yesterday and noticed that the ring clamp for it was rubbing the hose I had put on there... :x Quote Link to comment Share on other sites More sharing options...
