Lots to think about J.B. thanks for that.
Can’t see the pic John but I know that one well.
You make a very good point about 2” SUs. The problem with all this is not having back to back tests on the same engine and conditions. Yours is about as close as it gets.
As for ZT racing, they are producing great power at 8k rpm so for us mere mortals not racing, flow should not be an issue. But again, you make some good points above also. I guess all of it is about compromise somewhere. Even with DCOEs many many of them are not set up properly to deliver good power lower down, it to do that you have to choke your high flow carbs to achieve intake velocity for lower revs which kinda defeats the object of them. But that sound!!!! Yummmmm.
SUs will never produce peak power like DCOEs but in all of this, I look foe the total area under the Torque curve and across the range which is what makes a street car tractable and fast without having to be thrashing along.
Around 2.1k ish and 3.5k rpm I get horrible reversion.; as seen on the web cam. There are many theories but once I figure it out/stumble upon the answer, I will put up my results. For now, I am trying to get the low end leaner to minimise the reversion and richen up the top end to maximise power when on song.
