That would be a very loud ride

  1. I think that if it goes fast it should be loud.

  2. Ear plugs and a helmet will fix that. I think it's a Porsche 718 which succeeded the Speedster in the late '50s.

    1. Yes, the RSK variant. Pretty cool then and now!

  3. The intake honk at wide open throttle with those open velocity stacks is rather loud if your not wearing a helmet.

  4. Im confused on the intake. Looks compressed, but has open velocity stacks?

    1. It’s an air cooled 4 banger that’s normally aspirated. There are velocity stacks on the 4 carbs. The big blower you see is an air fan to move air across the engine.

    2. I had figured out most of that. So the turbine style supercharger also helps to cool the engine. That's duel function genius

  5. The Porsche flat 4 was one sweet engine, even detuned for the road. I had a 912 I bought from my engineering professor who taught me how to wrench it. Super light and agile and 102 hp was plenty. Drove it from Gainesville Florida to San Francisco when I graduated.
