Dan.....You are not missing anything. It only states ground RPM of 16,500, not peaked, or at least this is how the CD's interputed the rule. This RPM is a random check on the start line, ready for takeoff. This 16,500 number was not something APRA adopted at first. That was AMA. Most TT's will turn from 15,800 to low 17,000's peaked, and other engines on the list also, but of course no body launches at peak, mostly 500 / 800 back of peak, then the 16,500 number is no problem. I think this is not a good number to go by, because engines unload differently. Thats why APRA tested all engines with a flying prop, & unload prop. We found the Webra's, Rossi's, ABC Super Tigers, MVVS's, etc, blew the doors off the cheaper engines from the tests. The engines that made the list were K&B 4011's, ASP .40's, Super Tiger GS .40's, Thunder Tiger Pro .40's, OS FP .40's, and others. Over the test of time, the TT Pro .40 was found to be the fastest on the list, so thats the engine most everyone migrated to, with the Super Tiger GS .40, a close secound, so you see it not a single engine event. The TT Pro .40, was the one most wanted to use, because of performance.
AMA 422 rules are close to being workable, but it needs a little more work.
The way the rule book is worded for 424, I could see a Nelson / Jett .40, with a factory supplied canned muffler, backed off to 16,500. I have tested this setup, and A Nelson, with the mini pipe, out of the muffler, will turn the APC 9-6 over 19,000 RPM peaked......Do we need $350 engines, or engines that could turn over 19,000 RPM's peaked, and expert pilots lapping the entry pilots 3 or 4 times in 424 ??? I think not. See my point ? We desperatly need to get the 424 rules figured out with no loop holes. Until that day comes, APRA, NEPRO, etc, will be the successful races. This has already proven, by the test of time.
I would love to see 424 flown at the NATS, and I think Mike Condon could run 424, as long as it was according to the AMA rulebook, and he could run the APRA style provisional 424. Mike "can, & will" run the NATS however he see's fit, and that is his right ( thanks for the cart Mike ).......PS...What do we do with pilots that might be considered experts, that can't, or will not fly Nelson / Jett costs & speeds.....Shoot them ? Ask them to retire ? Buy them a Bass Boat, or a Girl friend ?.... APRA / 424 is a fun, & some times relaxing sport, that you don't have to get a loan, or have twenty year old reflexes, or all the extra time, to participate in.....Is it right to shut them out of this event.....Come on you guy's !....Speak up !...Am I the only one that gives a crap about you ? Maybe I'm wrong. I hope not.

Formalized Already - 
424 Unification - 
and that is where it will do the best for us all overall. We don't need another event with "Speed Creep" - (what is that anyhow, this is racing!) nor do we want "Dollar creep" - or "run" - as the case may be. We will do nothing but chase away ptoential pilots and the cry for a "true" beginners event will come forth from the ranks once again! I have heard this before and I would like to stop from having to hear it again.
