Even if you just use it for comparison to your next project you have a baseline of port energy vs. Performance. If your next set of heads have more port energy and perform better you know you are on the right track. Just another tool, more info the better. I would be glad to do it for you but you will owe me a beer when you visit. Thanks, Charlierandy331 wrote:What would knowing the port energy tell me ?

I've calculated the port energy on several sets of heads I have dyno results on, and don't see a connection to power.Carnut1 wrote:Even if you just use it for comparison to your next project you have a baseline of port energy vs. Performance.

The only trend I see is ported heads are higher port energy than un ported, but within the ported heads the higher ones don't necessarily make more power.
Tommy Boy's heads would be 23ish at peak lift I think.
I have to decide what to spend my limited amount of time on.
I have a thermometer in my test bore to collect temp info during a flow test,
a static pressure port for the spark plug hole to collect static pressure at the top of the bore vs my test pressure,
Velocity probes for the ports,
Velocity probes bent to probe the port while an intake is bolted on,
etc,
It's a lot easier to collect flow bench data than it is to get it all correlated to power.

VERY GAY
Thermometer in the bore sounds interesting, what has that told you
Re: Budget pulling truck engine named (Tommy Boy)
You're not going to but your thermometer in my bore
but I' like Randy's thinking outside the box

Your taste in music really tells me a lot I am disappointed that you didn't go with the Pet Shop Boys! But then again I guess human nature is https://www.youtube.com/watch?v=ST86JM1RPl0

Re: Budget pulling truck engine named (Tommy Boy)
Well if the throat isnt blown out and the pinch isnt too small looks like you have good fps for the average csa so at least the heads arent butchered in the normal chase flow only wayrandy331 wrote:FlowZ for the 034 Bowtie's on Tommy Boy.Carnut1 wrote:Even if you just use it for comparison to your next project you have a baseline of port energy vs. Performance.

I will try to graph this for you tomorrow. Thanks, Charlie

In order for the graph to be accurate I will need flow in these increments and sizes of intake opening and exhaust opening as well as throat diameters. Take a look at this sheet for input info. Thanks, Charlie

Got no flowZ below .200"
Very seldom flow anything down there.
