Just curious on how many have experimented or bench raced with the injection angle of our fuel and bowl configuration best suited for high rpm operation? Just something I have been day dreaming about lately.
(read: spend on a performance engine) .
Lots of work has been done in this area. If you want to get the good bowls, you'll need to call around and gain trust (read: spend on a performance engine) before any knowledge can be released.
Get rid of the flycuts.
No, 230/240* 0.360/0.360" cam could still be used.
In the open-chambet type, the mixing of fuel and air depends entirely on spray characteristics and on air motion, and it is not vitally affected by the combustion process itself. In this type, once the compression ratio, maximum operating speed, and operating temperatures are selected, the delay angle is determined chiefly by fuel characteristics. Engines of this type are very sensative to to spray characteristics, which must be carefully worked out to secure rapid mixing.
The engine builders that I trust already have the actual cylinder pressures of these race engines. Some of this data is incredible, yet it lets you understand why some designs work.Also check what Haywood has to say:

I need to just spend the money and get a copy of his book.
I have been curious to see some testing on dynamic cylinder pressure.
