Tom, I really enjoyed your photos of vintage aircraft engines. They are truely facinating. I recently visited the Pratt and Whitney assembly plant in Middletown, CT, to discuss instrumentation requirements on an F22 Raptor engine. The company I work for, Hamilton Sundstrand, makes the fuel control f...

Waren, Thanks so much for the link. The Pyrometer Instrument Company makes some very trick (read high tech) instruments. I read thru some of their technical notes. The way I understand their technique, they shine a laser on the IR target surface and measure the amount of energy that is absorbed. Tha...

Good one Rudy. John, Yes. it's the relative readings we are interested in. Fluke makes some fine instrumentation. We use a lot of Fluke instruments at my place of work. I have a Fluke automotive meter that works pretty well, but the inductive spark pickup doesn't seem to work for rpm on my Electromo...

Hi Warren, A thick, drilled gasket, with a suitable fitting could work nicely. Just take care that the surface contact to the carb and manifold surfaces are not damaged or distorted and that no air leaks result. John, I have no experience with a non-contact laser thermometer. I'm not quit sure how t...

Temperature measurement can be an aid in tuning, especially at start up and at idle. To be really useful, it would be a great asset to be able to measure and record the temperatures of all cylinders repeatedly and simultaneously. This could be especially useful in identifying which cylinders are fir...

A.D. When you get the new carbs in , fit them, balance them, and set the idle mixture. Ensure your ignition timing is good, advance is smooth, and that all plugs are firing. Change the oil and filter. I'd then recommend you get some miles on the car, maybe 500 or so. Ensure you have good oil pressur...

John,

I believe you mean P=I*I*R, not P=I*I*V. R is expressed in ohms if P is expressed in Watts and I is expressed in amps.

Regards,
Bill

Jason, On my 78 308, all the way up on the stalk is lights out. With the knob on the end of the stalk twisted clockwise, the head light buckets go down. Twist the knob counter clockwise and the head lights buckets rise. Push the stalk down to the middle position you get low beams. Push the stalk dow...
