tb coolant bypass question
I was just wondering what kind of benefits you get from doing this coolant bypass on the tb..I've seen alot of people talk about it but never heard any pros or cons..I'm trying to figure out why it's there in the first place,I have an 86 if it makes any difference..anyways just trying to decide if I'm going to mess with it or not..thanks

Since you are no longer heating the air as it pass through the TB, the air is cooler (difficult to measure)...cooler air = more power (again hard to measure)....never seen any dyno numbers on this.
Biggest as far as I am concerned, is that you don't have to drain coolant if you need to get TB off or remover plenum/runners. That alone is worth the small amount of trouble to do this.
I did it several years ago without any problems.

In practice the intake / TB gets so hot from engine heat TB bypass has no effect but as you say makes life easier

It mainly cleans up the front of the engine and makes the work space roomier. If you were in a very cool climate it's probably best to leave it hooked up, if not bypass it. There are many threads on "throttle body bypass".

thanks for the info,I guess I'll go ahead and remove it then..whats the easiest way to go about this,can you just pull the hoses and cap them or do you have to connect them to each other..thanks again for all the help

On my 1989 I just pulled the TB hoses off and ran a 48" piece of hose from the front of the engine to the firewall heater connection. Measure everything out and figure your route before you buy the hose. These cars are sometimes a little different year to year. You don't have to cap the TB, no in, no out.
