Hi Fulvisti,

Did anybody from the DIY performance department ever consider to get rid of the watercooled (or indeed: -heated) intake manifold? Even the special racing manifold for big webers seems to include at least some of this heating.
I'm curious to learn experiences from people who made modifications, like heating only cilinder 1 and 3 to get all 4 evenly heated.

Regards,

Bart

The ports aren't primarily for intake heating; they're the main water ports. And you'll notice that the front (nearer the rad) water port is smaller than the rear port, to equalize water flow through the head. If you try to fabricate a manifold without them, you'd need to create some other route to get water from the engine to the radiator.

I agree with Ed.. It's a cooling issue not a heating issue. The coolant is there to remove heat and send it to the radiator but also the surface of the motor is a radiator in itsefl as is the manifold.
