Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra small-combustion-chamber head. Thats what it is. It's a J1 Elantra cylinder head. Good luck finding another one like it. (read more)... In Cylinder Head 106 I talked about the mainstream porting theories as they are discussed. We looked at a cylinder head that I have thousands of dollars of professional work performed on, and a bone-stock second-generation head that I didn't port. In this video I just might do something you haven't seen done before. For some, that may be uncomfortable. The port and polish job I perform here is what I think will work best for my current build. This is not an extreme killer port job. What will be different here is where port textures are concerned, I will be following the advice of a reputable source that will remain un-named. You're free to port yours differently than I do in this video, and I give you that out, around the 20 minute marker. The Hyundai is far from being an ultimate-performance build. It's a $400 box of scraps with nothing but time invested. It's perfect for this video. My finished product WILL be an improvement over what I had. I don't yet have access to a flow bench. I still have an achievement to un-lock. As far as you should be concerned with the techniques I employ... without flow numbers there is no evidence of what this will do, but we will gather lots of info from dynp sessions and drag strip time slips. If I could test it on a flow bench, I would. There are MANY, and when I say many, I mean thousands of flame war mongering pirates floating around on rough seas with a hair trigger cannon finger itching to fire if you port a head any differently than what the herd mentality says to do while porting a cylinder head. I cover the herd mentality because it has merit. It's been tested. Tried and true. But I don't follow it to the letter of the law. I'm definitely not here to de-bunk it. I would port a cylinder head differently for each build based on how that engine was used. There's an extremely valid reason why relating to air speed. It's not the texture of a port that maximizes the effect of fuel atomization, but the velocity of the air running through an x or y sized valve. The driving factor in this is the piston speed. I'm not going to give you the technical information, but will refer you to information about the Lovell factor. There's a better description of this in the links below, and even a calculator to help you find your engine's sweet spot. Why the Lovell factor is important: https://www.highpowermedia.com/blog/3346/the-effect-of-valve-size Lovell gas factor calculator: http://www.rbracing-rsr.com/lovellgascalc.html Only people who have flow testing equipment know for sure what really works and have the capability to produce a perfectly-matched port job for the ultimate performance build. Those guys know the definition of ultimate, and THEY are floating below the water Aegis-class submarines ready to blow your comment up if you don't know what you're talking about. They don't care if you're an armchair mechanic or a herd of pirates. I will say, they're zoomed in pretty close on me right now, and I'm expecting to take a few hits. My work will be tested based on Dyno and drag strip performance, and the results will be posted here. Fortunately, those kinds of videos are a WHOLE LOT EASIER TO MAKE!!!
