The newer 2072 has increased top end over the 0801 as well, so it would be the one to go for I would think.
talking 2072 grizz1 I was running in the 7 port with the 2047 cause I was reinforcing the stinger I broke on the 2072 by building up thin layers of jb weld..anyway 7 port was running just sweet throughout the rev range with the 2047..switched it for the 2072 and ran it down the straight and it was practically 4 stroking at the top end.had to close the hsn a full half turn..didn't touch the lsn and now it runs spot on perfect with the 2072...
there's your xtra runtime right there..1/2 turn shut on the hsn..switched the pipes back to test I hadn't made some other adjustment inadvertently but nope..2047 open hsn 1/2 turn..2072 close by same amount..
I do prefer the sound of the 2047 though..nice deep throaty crackle.plenty of rooooolled r's .the 2072 is louder and is a flatter harsher sound..but as sound is secondary and of no importance performance wise.what the hell.
MG66 might be here today..surely this week..
