I figured out in my long ass post, I didn't post a comparison between step 1 and step 2 of the MHR.
While reading all the 35 pages of this topic about MHR, I've read that a lot of people are quite dissapointed with the cylinder, because it doesn't pull out the expected power.
But I think of it in a different way...
Most of the setups I've seen in those 35 pages are soft-tuned, some have rotary intake, some have low cyl timings under 125-185°, and NO ONE has a widen exhaust port. We're talking about a bridged cylinder, that comes with a 70% exhaust width. Why would you take a bridged cylinder and use it with a 70% exhaust width? Makes no sense (and keep in mind I still have it at the original 70% width, but I think that was a mistake from me, to raise the timing BEFORE trying to widen the port).
And also: why use an MHR for a soft-tuned engine, when there are better options, like VMC Stelvio or Quattrini M1X? What I mean is, 2 exhaust types, one single port one bridged port, if both are at 70% width, the single port will flow better I think, because the gasses will not be divided in 2 by the bridge.
In my opinion, if you want a soft tuned engine, that pulls a 23/65, that has early torque, that works with low timings, then get a Malossi 177 sport, or a VMC Stelvio, or a Quattrini M1X that are the best options, in my mind.
MHR means Malossi Hyper Racing. Not Malossi Soft Tourer :D
So give it what it really wants! Give it 130-190°, give it an 85% wide exhaust port, give it a 38mm carb on a huge reed block, give it an exhaust that comes into resonance at 5.5 - 6k rpm, give it a 22/68 primary with a short 3rd and 4th gear cluster! Then we will see the true face of this 177 MHR. I might be wrong with this way of thinking... but when I went from step 1 to step 2, the torque I lost at lower rpms was quite small, and the power I gained at higher revs was HUGE.
As I said, I forgot to post a dyno of step 1 and step 2, so here it is. Step 1 with PD Bullet M1X and Megadella XL, vs Step 2 with the same 2 exhausts. Check the difference and tell me: does this MHR work better with standard timings or with much higher timings?
