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

Stan

And publicize the detail's of your build so it can be copied. :D

If it is a "Race Engine Challenge" then pick a race class and have everyone build an engine for that class under their rule restriction...After all that is what Race Engine builders do isn't it?

They already have that...it's called Prostock. Rolling dyno's. That's a good idea though, using a known class rules to build to. Would be interesting to see if some of the builders that are in the winners cars could be bested by some other people. Sometimes a fresh set of eyes on a project can see something that people who work with them everyday overlook out of complacency.

That sounds like a decent idea as long as it is a class which has competitive, multiple brands involved.

Something like this that would include power adders would be a change http://www.mirdrag.com/v2/rules/pdf/2015/15_x275.pdf and then an NA class with a ci and valve angle limit but everything else goes. not sure if you would open it up to 4 valve engines or not.

Just a thought from someone who wishes he had the time and $$$ to enter one of these events...

Give everyone the specs for a realistic car configuration (or for two classes, one more limited and another more serious) that can be modeled in a proven drag strip simulation program that allows entering full power curves. I'm thinking vehicle weight, gearing, tire size, # of trans gears & the gear ratios, converter stall (assuming an automatic), vehicle drag coefficient, and... ?

All the competitors build an engine to the modeled application, test the engines on the same dyno (yeah, typical contest stuff), then the actual power curves for each entry are plugged into the sim program to see whose build "runs" the best predicted #s. It's not perfect, but it does apply something of a reality check on the results that an arbitrary scoring formula wouldn't necessarily show.

We could all build virtual engines on desktop dyno and enter in a virtual engine masters challenge...lol. Best part its somewhat free and nobody gets their hands dirty.

Don't laugh... I'm 99% sure that PHR actually did that one year in conjunction w/their EMC competition.

Nice...well nothing surprises me in this world much anymore. Who wants to drive a racing simulator...not me. I would rather make my own.

Don't fall into the trap of killing innovation and modification like the EMC has done.

Amen!

And also don't fall into the trap of pandering to the largest demographic of readers like EMC has done.

From what I hear through the grape vine you don't have worry about them pandering.

That's good news. let the engine builders experiment within some rules, keep them liberal enough so non mainstream engines can compete.

I think you should keep your first year of doing this simple so it goes smooth with less chance of things going wrong.

Although I would like to see a small block limited cube class..min 355, max 365. No factoring, factory block, non factory stroke/bore ok, any steel rod, any ring pack(3), wet sump, any catalog pan, any headers that fit the dyno(no crossover or upswept) , 11.5 comp? Any cam(no mushroom lifters), .750" max lift, 1.8 max ratio rocker, iron or aluminum 2 valve head(no billet or custom one offs), any port mods within the port casting(welding &epoxy ok), int port entrance must be within 1" of factory port centerline horizontal&vertical, any valve size(no Ti), any cast single 4 intake with a catalog #, any port mods within the casting. Carb, EFI ignition?

1975 and earlier chev, ford Windsor&Cleveland, Pontiac, mopar, AMC, Buick, Olds ...could easily fit this cube range.

3500 to 8k 8)

GMrocket stated don't fall into the trap of killing innovation and modifying parts. Thats my main bitch at NASCAR nowdays, they (NASCAR) have the teams (engine builders) will/desire beat down to depressed i would think by now. MPO Mark.
