Thread: For Spark plugs fans . Indexing

I'm still waiting for Mr GAS to come in and say it can't be done on Rover heads because they're rubbish.

Smoky Yunick did extensive dyno testing on this (and many other tricks that some engine builders were obsessed with) and found no discernible benefit.

Too true.

My favourite chuckle with performance seeking is the dragsters - especially top fuel - where you see how much money is spent on performance from the engines, and lightening the total vehicle - space-age technology abounding - and then an overweight drag car racing driver jumps in.

Save some money on the burgers and chips, save a lot more in reducing the weight of your drag car.

And years ago I did dyno testing of tricks that other engine builders had thrown away and picked up repeatable improvements.

It all comes down the the specs and combinations used.

I think it was Isaac Asimov who said, "People who think they know everything are a great annoyance to those of us who do."

So does mean I'd be wasting my time indexing my glow plugs, because I need every tenth of horsepower.
