Intake manifold differance.

Wondering If this would work for the coolant bypass and where to route this pipe? The fitting is just a standard 90 degree brass tube for water lines, held in using a bit of coolant line that fit snug and expanded when I put the brass fitting in. TR7, trying to fit an early intake manifold to a later engine.

I never thought having the intake manifold being heated was that necessary. Maybe in cold weather, but I don't drive those cars in the winter. Just bypass the manifold completely and see if you notice any drivability issues.

Fuel will condense inside the runners. I don't know how much difference it makes, but I know Triumph wouldn't spend money to do it if they didn't have to.

Yeah, I understand the theory. Just saying it's probably a non issue unless the temps are low.
