Dave walks us through the journey of making the toughest shape in head porting, a circle! He shows some of his techniques on how to keep a circle a circle.

i like his “less is more” attitude you see in all his work not only does this theory prevent (often) excessive jobs out there-his usually not asking you too spend all the money if it’s not needed too reach your goals.

Have u ever used a steel rod with a slot cut in the end ,the sandpaper go in the slot and makes the port perfect formed
@headgames Жыл бұрын
yes! But the flapper won't make it perfect as a roll. Only use the flapper on the short turns.

Love it, thanks for sharing. Anything in the 4g63 realm would be awesome. I'm about to pull the drivetrain in my 95 talon and go over somethings. I have some spare heads to try on, if I could do some port work while it's apart that would be awesome. Mild street build for daily driving. Also I love knowing what not to do, so avoiding myths like gasketing matching is awesome to know. Knowing what a mistake is and avoiding it is priceless

Thankyou. You could polish it only and that would help,... but how much. I bet it would help. I know this sounds crazy but the the German pilots in WWII would have their technicians buff the wings to get their interceptors to go faster. They knew their stuff. @@headgames

Very nice. Seems like patience and a relaxed attitude is the best tool when porting. Looks really effortless 👍 I have oe-heads where the bowl is too big. Have been trying to find out what to do to remedy this. Is there some tricks with porting one can do or is it just filling with epoxy that is the solution? Ive been a little hesitant to put in epoxy, not sure one can trust it to stay put on a street engine? Engine is a gm 3.4 v6.

Love all the info, question for you why do hand vs CNC? Once the program is set up for the machine, it can duplicate it numerous time
@headgames Жыл бұрын
Yes we have many heads digitized. The CNC is much faster.
@davidparker9676 Жыл бұрын
CNC works to shape the port but I've never seen a CNC beat the finish done by hand. If you are doing a limited number of heads, or you have different ports for different customer needs. It makes no sense to program the CNC for such rare jobs. CNC is for production, it only duplicates what was originally ported by hand.

I have a Nissan with the “hart” shape intake, looking to put itb’s on. What would you do if anything, change the intake shape to match? The itb intake is round and with what little knowledge I have, it seems like I would have a slow moving airflow just after the round itb intake. Any help would be appreciated! Loved your podcast interview with hp academy.

@@headgames thanks, but I think this would be a waste of your time. Appreciate it. I can’t imagine this is on you radar. However I am in it to learn and interested how I can aid flow/volocity/ ultimately power. As I said the transition isn’t smooth and was really thinking of reshaping the intake to match the ITB runners. If I had a pipe and half way down we had a step, making it wider. The roof of this pipe is now almost doubled but returns to original size quickly. (It where the og injector would be) this must adversely affect flow and turbulence?

4G63 heads are another one that make no sense to gasket match. It takes too long to teach fluid dynamics, velocity and reversion to customers, I just say sign here that I advised against doing that X. Less is more, especially on a street car. Don't call me saying how much torque you lost, this is what you asked for.
