hehe nevermind i found something in archive topics https://honda-tech.com/zerothread?id=400842

boosted hybrid

That link is a good one. I'll have a good DIY port and polish up this summer. I have zero time to write anything up with my finals, but my article will be forced induction based.

if you dont know what you are doing i think the most i would do is port match. i dont think i would go much farther that that unless i was more experienced with it. just my .02 which isnt ****

boosted hybrid

If you understand fluid dynamics you can apply all sorts of equations that can tell you approx. what will maximize flow and what rpm range, or boost level it will be most efficient. There are plenty of factors: lift and duration on cams, valve shape, valve size, port radius and overall shape, etc. I will be doing a full analysis of the d-series heads using fluids to tell me the answers of how much material i should take out, and in what quantities. With boost the overall ability of the head to move cfm is critical more so than an all motor application where port size and shape dictate the velocity of the air, and whether it will be turbulent or laminar accordingly. All motor head porting is out of my league, other than a mild p&p and port matching.

well the only thing i dont like about the write up i found is no pics....im a visual person. I understand everything i read...i just like to double check myself with pics...so it would be nice if anyone had a write up with step by step pics

im the same way bro, i like to see if i F'ed up not read it. good luck with it

I don't think a Dremel is as fast or has enough torque to be a proper porting tool.

USDM 4G VTEC on here did it with a dremel. I'll let him post pics of it if he wants, i'm too lazy to look for em

die grinder for $15 beats the hell out of a dremel for $30, assuming you have a compressor that is. I would love to read about your project boosted hybrid. I have a z6 head that I refuse to put any money into but time with the grinder would be fine, if I actually got some HP from it. It seems like the gains will be really small compared to turning the boost up but i guess everything works together so every bit helps.

After you create a head that flows better will you make the same Hp at a lower boost because the head gives less backpressure? if not, why?

the carbide bits and coarse sanding drums on mandrels are very effective and easy to control, the biggest problem is extending far enough into port.
