To me a 240/240 @.050 on 110 centers idles just fine, but not at factory idle rpms(1100 in neutral is just fine)
Untill variable valve timing becomes available, a 2 valve 4 stroke engine becomes a trade off in many ways, todays 4 valve engines release many of these handcuffs, but not all.
A 2 valved engine is todays equivilent of a "Red headed step child", don't care how well it can work, just won't get it done to suit everyone's want's(I used to have red hair before the grey took over, so piss off)
It still comes down to head flow capabilities divided by displacement it's trying to feed, Donnie has an advantage over Street Lethal on displacement per degree of crankshaft rotation, allowing him higher crankshaft speed before his pistons feel the effects of drawing thru a straw of restricted intake ports/valve area.
I'm just stating what I know, Donnie has probably the highest output of a production based 3.8 Turbo here, it's ludicris to try to compare to a Stage2 headed engine.
The only other I've seen go as fast/faster was Buddy Cox back in the early 90's, he was using a Duttweiler built engine with original Stage 1A heads (which were what Ted Wayman used for his M&A casting derivitives).
I'll bet few of anyone here have ever actually "Chased" a dream, I see a bunch of devout followers scrambling after the latest and greatest parts just to say they got'em, but never use them effectively, but always asking others "Why" did my heads blow/cam wipe/can't rev/no boost/my ****'s fubar, etc. Year after year, the same questions for the same problems.
The guy's with Stage 2 equipment are swinging their big dicks against a Stage 1 equipped driver/owner, funny will be the end game results.
This whole thread should have been a Q&A about the real "Potential" of the small valved(production based) V6's, he's not far off what many of you actually run, yes he runs Methanol, but he isn't even running close to the limit there, if anything his methanol is not really productive untill he's in the 45 lb range.
Strange as it may seem, he's probably hurting power output at 30 lbs and less(he's at least 2 full points low on mechanical CR to be of benefit)
Take it for what it's worth, most of you have handcuffed yourselves with hydralic roller camshafts(My hatred is well documented) which limit your "range", so it becomes a "Monkey see, Monkey doo" follow that dude in front of you, which now again a race of boost guages, and blown head gaskets, etc, people are getting better about not driving over their crankshafts, but that ain't saying much.
I've pm'd my thoughts to Donnie, he is the only one I hope succeeds surpassing his dream, because he had the balls to step out of line and ask...."Why"
Good luck to all, but keep your head out of the ground,
Kevin.
