What could we learn if each engine had in-cylinder pressure equipment? :mrgreen: That would be cool alongside the dyno sheets. =D>

Doing a standard xxx RPM dyno test has the engine see a variable load during the dyno test.

The inertia dyno will have a fixed load on the engine and show a variable RPM acceleration. The highest RPM acceleration rate will be around peak torque.

Stan
Average HP does not necessarily equate to the best engine in either scenario. The best engine can be figured out from both types of dyno tests, but the standard dyno requires some "more than basic math" to do it, and the inertia dyno can be done with direct measurement, provided the right thing is measured.

I would like to see rules that motivated innovation/fabrication rather than use of "off the shelf" parts.

Recombining decades old parts has become way past boring.

And a huge thank you, I fully agree.

The best dyno for this test would be the dyno Mike laws built and sold to that other company I can't think of right now.

That would be the dyno you want.

Revolution dyno or something. Sucks being old.

I'm sure there is going to be late model Hemi and LS engine so SBC engines should be allowed any valve angle head
and 55MM cam cores.

Why don't you skip the Dyno and put everyone's engine on a dragster and run for best et. It is a race engine challenge not a Dyno challenge. I don't care about what Dyno number a computer picks for me, I care how fast my car is. Set the trans type as powerglide and you bring your best engine combo, trans and converter. Brings more sponsorship to the event too. Trans companies and converter companies. Something different to think about.

Some of these extremely expensive, time consuming and almost impossible suggestions are rather humorous. \:D/

Especially ones by those who have no inkling of ever placing their own entry into one of these competitions. :roll:

i like this idea tell everyone bring your converter and conversion to this bell housing and motor plates that fit this chassis, let them know what the car weights and what gear is in the rearend, tire height and what low is in the powerglide. then make them hot lap it three times and quickest average wins.

Walter,
Want they want is to spend your money and have you do the work, but have you build what they want. :lol:

I'll start a contest where I will build something I'm really good at...like left hand permalloy wingdingers. I have you know I build the best left hand permalloy wingdinger in the country. So If I start my own contest building something that nobody else builds or cares about...who cares. It takes special kind of people to want to go to an engine masters challenge. Trying to get more people to participate and watch or whatever is a difficult task. I would love to build an engine for any of the challenges, but I'm broke from racing. If I owned my own shop where I had access to my own machines I would be more tempted. If I owned my own shop I would hopefully be busy building and machining customers engines making money. For those of you that enter I give you props...not easy to do and not cheap.

Just exactly how much does one of your special permalloy wingdingers cost?

How many do I have to buy to get the volume discount?

They are quite expensive...lol. A wise man once told me "Something is only worth what someone is willing to pay..." If that clues you in to what a left hand permalloy wingdinger would be worth.
