What happens here

The intake manifold is ported and polished, and the intake ports on the cylinder heads are slightly raised to optimize airflow. This work aims to significantly improve both intake and exhaust flow, measured at around 35-38 CFM for intake and 14-15 CFM for exhaust. This fine-tuning of airflow is crucial for maximizing horsepower and efficiency.

Goal: Optimize airflow through the intake and cylinder heads.

Tools and materials

  • Cylinder Heads — Porting and polishing intake and exhaust ports
  • Intake Manifold — Porting and polishing to improve airflow
  • Porting Tools — Grinding and polishing ports

It was built just fine. It was just used in the wrong application without the update. What did you do to the manifold? It looks all shiny now. Jim went in and did the plenum. He did some work in the plenum and then when he he updated the ports on the heads, he had to raise them just a little bit, but he he got a lot of the We went from a 2100 intake valve to a 2150, [clears throat] which is still isn't that big. So, that'll be an improvement. Improved the seat ring on the flow, the intake port, little bit on exhaust, and then he did some work on the intake. How much flow did the heads pick up from what he did? I think 35 38 CFM on the intake or exhaust. Intake. Exhaust was I think 14 or 15. I don't mean I don't know a ton about that stuff. Percentage. It's about seems like a lot. It's about 10%. And there was more there but you know what we're trying to do here we felt like would be good for this
