Just so you know, the TB bypass is NOT a good thing on a car that operates in cool climates. There is a case for it if the car is only driven in warm climates, or on the track, but that's it.

It may be a concern for some cars, but I live in Michigan and it's never been a problem.

Different cars, different throttlebodies, different engine management, different throttlebody heat arrangements.

The pre-2000 Northstar throttlebodies are coolant flow heated to prevent bore and idle air passage icing. Deleting that slight amount of heat accomplishes exactly nothing. If you think it does, please post the before and after dyno sheets.

Not bad for a thread that is 8.5 years dead...............

WOW! This has to be the earliest thread I've ever seen exhumed by somebody.

Earlier year Northstar modification attempts....:sneaky:
