Hmm, strange. Is the top end of the 1.5d better than the 8L if you use it in an open area. I can kinda understand how the 8L might get to a faster speed by the end of a short drag race, since the small rotor might spool up quicker, but if when given room to get to full speed the 8L is still faster thens something's not right, because the neu should be reving higher. Have you played with gearing much on the 1.5d? I have the 1515 2.5d as well and from using that, it's kind of hard to work out how a 1515 could give poor performance.
If it looks like a poorly built motor, have you talked to neu about it?
Have you tried the 8L on the MGM, to see if it's not the MGM that's limiting the rpm or something?
