I think a little higher would be good as it has its own specific problems never addressed or tested becuase the torque. So as the test conducted by grubee is of a smooth rpm it does'nt have a gerking torque test conducted. So it does and it doesnt kinda.
I would also tend to say no because of the low end torque. As I need low end torque I have it tuned there.
So as the rpms climb to about 6K the sound and torque smooth out from bwaw bwaw to vrooom. So at the beginning of the run and after a shift change I have the need and ability to climb into higher rpm making the need to shift.
If I use 80 90 weight gear oil it should stop the grenade tranny from from blowing and stop the chop chop clutch stuff.
If you notice in the cheap video I have thats described as video with blown out exhaust is sitting there at idle speed so in-fact the engage time might be ok as far as engagement.
I you can picture a torqued out motor pushing open the clutch and letting it compress all in a single stroke or rotation whatever you call it.
I was just trying to clarify the reason there was old information that wasnt mathcing my situation.
Heres the video with exhaust leaks and back blown out of the exhaust.

I had some two other videos but the sound wasnt on. I was rather busy trying to figure why the chop chop problem was going on. Luckily I only strecthed some cheap chains.
