O.K., let’s get some good tech discussions going. I’m getting bored and
Tony Vicarage has chosen to ignore me and isn’t answering any of my
questions, so here are somethings to chew on.
1 - The Jaguar specs say that the ideal timing (for my 3.8 SI)is
10degrees BTC. I was recently speaking with someone that strongly
recommended 5 degrees BTC but no more. Retarding and going up to
10degrees After top-dead center is fine but advancing beyond 10degrees
BTC is very bad for the car. Any conjecture?
2 - I recently adjusted the mix in the carbs since one carb was running
obviously lean. The same friend went pale when he heard that I had been
running a lean. He said to always run a little rich with these cars
which might make you loose a little power but running lean is very, very
bad for the engine. My understanding was that running lean was not good
because it would just burn up the valves and plugs quicker and cause the
engine to run a little hot, but not death to an engine. Any conjecture?
3 - My friend also totally disgarded the idea of using an air-flow meter
(like Colortunes). He feels that they are entirely inaccurate with
E-Types. I must admit, I have one and have used it on my Austin-Healey
with only modest success, but never found them to really work on the
E-Type. Any conjecture?
