Air gap manifold question
Has anyone had driveability problems with an air gap manifold?
I'm thinking about running dual quads on my T and the manifold is available in both air gap and non air gap. I've never run an air gap.
I know that the air gap manifold helps build horsepower by allowing the A/F mixture to stay cooler(and denser). All the dyno data I've looked at bears this out, but dyno pulls don't always tell the whole story.
My question is about low speed driveability. Most of the stock engines I've seen that had manifolds raised above the block had some means of heating the runners(water or exhaust). I know that engines I've had with blocked off heat risers were very cold natured.
