Doug,
I’m just catching up on the emails but WHAT do you intend to prove with your
test??? In my eyes, all you will prove is that you have the ability to
make three, albeit non-identical test runs, with two different filter set
ups. That is all. You are not PROVING anything UNLESS you know that the
car is optimally tuned on each set up which, as I recall, you are having
difficulties with currently. Are you going to spring for the dyno time to
verify that everything is correct prior to the “Test”
This is one of the fallacies that exist with “Performance” parts. Too
often, people take worn out components, replace them with new “Performance”
parts, and swear that the parts make a huge difference when in fact
replacement “Standard” parts would have had similar results.
Making more HP involves a lot more than bolting on a part or two. Change
the air flow, opps - now you might need to adjust the carbs. Opps, now the
standard needle profile might be incorrect. Opps, now the timing may be
adjusted. Its a PROCESS and to optimize the system the effects of the
change must be carried through the entire system.
Your “Test” does not meet any engineering or scientific standard for a
controlled test. It therefore can not be replicated, hence is of limited
value. In other words, its just the sort of thing that I argued with the
marketing department about :>)) What it will prove, for you, is which one
your car appears to run best on, given its current state of tune.
Do what you will. Have fun doing it. But don’t anticipate proving anything
because this sort of test can not do that!

In reply to a message from Ray Livingston sent Sat 18 Jun 2005:
And you haven’t proved one way or the other that the stock
setup is better than the K&N setup.
Here’s what I’ll do:
My father has purchased a set of K&N air filters from
Classic Jaguar.
I currently have a GTech Pro meter that provides accurate
HP/Torque readings, actual to the wheels.
I’ll run 3 runs with the stock filter on, and then 3 runs
with the K&N filters. If there is an improvement, the
records will show improvement. If it doesn’t, the test will
show that.
Hopefully, this will solve it.
