Keiths tach ahs alwasy showed 200-300 rpm less than anyone elses for some reason, Aero. . it's been reported so many times (by me at least) that i take it as a given. When keith, therefore, says 6300 with a menz 28-10, does that mean 6500 on everyone elses tach? An interesting question. So, if his engine is turnign 400 rpm stronger than HIS DA100 comparision motor, it's a pretty good indication that it will be 400 rpm stronger everywhere else too.

I have seen reports of the 3W106's at 6300-6400 with the menz-s 28-10 . .which puts the Xtreme (yes, it is) right at that powerlevel, which (as everyone knows) is substantially stronger than a DA100 by a GOOD 300-400 rpm. Then again, I've seen 6000 as the rpm for the 3W106 from several reports on this forum. Kind of makes you wonder who is more accurate.

400+ rpm stronger than a DA100? I have absolutely NO doubt about it.

As I said before. . hogwash.
