Which has me wondering why anyone would send you a 461 or a 661 with their hard earned money to hop one up. You obviously do not understand how they actually work! I also question your instance that pop-ups are better than squish cut, and that one ring is better then 2. You have continued to refuse to compare your saws 1:1 against other types of modified saws in dyno testing that would easily prove things one way or the other. But noooooooo! You are above empirical testing and analysis!
And yes, I am aware that there are other engineers here. At least one anyway. You are certainly not one of them.
You're showing your ignorance on so many levels, in nearly everything you have to say. You obviously know basically nothing about me, my saws, or my work. The proof's in the pooding, right there buddy. I have no need to go into my professional credentials. I've also never said cutting squish bands is inferior. I simply don't find them necessary. Again, the proof's in the pudding. Cutting the squishband is a valuable tool when needing to lower the exhaust, or need more compression than a popup will get you. That's not very often IMHO. Different people skin cats different ways. What's it to you? The only thing you have in this is a bone to pick, and who knows why. I never had any dealings with you. The simple fact that you need to exploit your supposed credentials and tear down mine speaks volumes!
