That is a great read.......
Here’s what stood out the most to me......
Look at these intake port flow differences(57cfm avg gain from .400-.700) .........and then digest that on a 12:1 514” motor with a decent sized roller cam...... the power difference was only 30hp in a true back-to-back dyno test.
Intake - SCJ / P-51
100 - 104 / 105
200 - 166 / 175
300 - 215 / 258
400 - 285 / 330
500 - 321 / 375
600 - 337 / 401
700 - 346 / 412
Pretty noticeable change in cam duration(on a combo that really seemed like it could use it) was worth 20hp.
Fully ported Ex port worth zero gain.
Does it continue on?
I was hoping to see what happened with their new TR.
Years ago when I was working with a builder trying to come up with a nice package for a couple of the local oval track classes....... and we tried all kinds of stuff that didn’t make any difference.
