Disappointed with my engine

Retroboy said
Like I said Mate it's called a discussion. I'm not talking fancy dyno results I'm talking real world outcomes and as I said there is zero similarity between a 14 or 1500 lb FED and your door car. The scoop isn't sealed so it doesn't offer anything or very little on the way of ram air.
You come across as a smart arse know it all incapable of discussion.

No, you are incapable of a discussion. I didn’t just test headers on a dyno. It’s also done at the track. The issue is you are so consumed with the thought that your car is so different from any other car on here you can’t see the forest for the trees. I’ll say it again. You are killing all your power at just below peak torque all the way to peak power with your headers. It’s that simple. You may not like that, but that’s what it is. The physics that make your RED run and move don’t change from a door car. To continue on that path just reinforces your inherent biases and cause you to strain at a camel to swallow a gnat. There isn’t a NA engine I know of that benefits from a zoomie header. And if it is, it’s a hemi and I doubt that. You can’t kill the overlap cycle and make power, and the hemi head has by far the best overlap cycle out there. You don’t have a hemi, or a canted valve wedge. You have an inline wedge head which the has the worst overlap flow going. Again, your headers are killing power. The chassis they are in makes no difference. If you are swapping out the zoomies and not gaining power, it’s likely your cam timing is as funky as your thinking on headers, overlap flow and overall air flow through an engine. Cam timing and header design go hand in hand. As for the “ram” air effect, that’s not what I’m talking about. Did you even bother to consider what I said about volume above the carb? It matters. Unless the unsealed part of the scoop has the same area as the opening does, it will still pressurize the VENTS and cause the engine to go dead rich at speed. You can’t put pressure on the vents of a carb unless you are doing it for a reason, like a blow through application. If you want to have a reasonable discussion with me, you have to get off your preconceived (and ill conceived) notions that dyno’s are “fancy” and don’t relate to the unicorn you happen to ride. When you do that, we can have a proper discussion. Until then, continue on as you’ve been doing. Your success is magnificent.
