| Re: Primary pipe length formula Adam,
Thank you for the information!
I have known you were out there from some of your other posts and was hoping you would jump in on this one.
I have one question if you have the time to run one more simulation. (I would love to have a copy of your software.)
What happens if you use a flat (180 deg.) crankshaft with normal headers? Does it equal the graph for the Bundle of Snakes on a conventional 90 deg. crank engine?
I was surprised by the graph of Primary Tube size. I would have expected the large pipes to have moved the torque peak up noticeably on that small an engine. Also the VE was very good – 95% up to 5,500 RPMs with those Heads (Is the exhaust flow really that high compared to the intake flow? That seems like a very high number for the exhaust.)
Thanks Again,
Kevin |
