How did you see that average power was down with the 104 LSA? I didn't see that. From 3500 on up on the test they posted the 104 was much better than both.
The 104 just didn't make peak hp was all I meant. Not down on power at all.
When you are talking low speed, what does that mean? Are you talking lowest possible RPM or the lowest RPM the engine will see under load? They are two entirely different things and the former is a rediculous expectation.
Low speed to me is idle to 2-3k RPM. Street RPMs.
The text says that Chase Knight says that the narrower LSA would affect torque from 500-1200 RPM. Was he guessing or did they do testing to show it?
Since it wasn't dyno'd at that RPM, I'm guessing he is basing that on the crappy idle.
That engine should have had a 107-108 LSA with a 105-106 ICL. Then you could run 242-245* duration in a single pattern cam and you would gain the vacuum back, clean up the idle a bit and make more power yet.
I realize some people want a Honda idle and 500 HP. It's impossible. There is a difference in an engine that idles at 900 RPM and will run power brakes and still makes 500 HP and one that idles at 1500 and makes 210.
