If you have 50 different "mules", that is a problem. The only way to do it with some sort of repeatability would be to have a couple mule cars, both weighing the same with exactly similar chassis weight distributions (not wheel dist as that could vary with susp and adjustability, I am saying exactly or near exactly the same weight and cg location). Then you have to be able to quickly swap out suspension packages into that mule car and have "the Stig" drive every one thru the same course, etc with the same tires (new each time) etc. Way too hard to have repeatability for true comparisons.
Cool idea tho' on the surface and would be great if there were a way to do it... and I do love the engine masters challenge. I am absolutely blown away (having been a race engine builder for a few years) by the HP per cube they are getting on pump gas at 6500rpm! Staggering - I was reading the last challenge, which I thought was the coolest so far is it was a free-for-all on engine parameters with only essentially a HP/torque per cube calc. Bad ass and the best concept yet as bore v. stroke v. rod length etc were varying like crazy. The top guys... just staggering. But that is a LOT of dyno time on a particular combo, trust me. I knew a couple of the entrants over the years and 100 dyno runs getting a good combo (not winning BTW) is not "crazy talk".

byndbad914:
I agree with your statement about all the different parameters.
Maybe the solution is for every company who wants to participate, bring their own Mule. Each one limited to any difference unless it is involved with their suspension.
Then it could be held on the same day, under similar conditions.
Many of the companies already have Camaro's/ F-Body's anyway as they had to have one to test and build their own products.
Good point.
What would you think if it was approached from that standpoint?
I look forward to hearing from you.

BTW: Yes, the engine Challenge is awesome and incredible.
