Flowed a couple more heads this evening.
I did a nice stock RH4 and a stage 2 modified head by a well known tuner.
The modified head started life as an RH10 and has stock valves and 35mm ports. Here is what it looked like.
Here is the graph, and yes I flowed it multiple times because I though there must be something wrong.
The green line is the big port modified head.
The yellow line is the stock RH4
The red line is a competition flowed fullauto with stock valves
The blue line is a ported fullauto with .060 oversize intake - it's going on my bike
The white line is the Maney stage two with .115 oversize intake valve and 35mm port
And here is the velocity graph
The blue line is the competition Fullauto
The blue-green line is the stock head
The red line is the Maney stage 2
The green line is the stage 2 that I just tested. Glad I didn't buy it.
