Hi Mike

The concept sounds really good, and different types of these have been around for many, many moons.

I think you hit the nail on the head though it is not testing the engine under load.

Can remember seeing a "Factory Trained Mercedes Mechanic" using something similar to set up the old dual solexs on a 190SL so some mechanics must believe they have specific applications.

What would be neat though is to set up an engine with all the cylinders having one so you could compare. Might work particularly well with Ford Pat 13 so the mechanic could look at the all while the engine is running under load.

If you get one do let us know what you think.

Cheers Phil
