edgehanger Posted December 12, 2013 Report Share Posted December 12, 2013 http://www.harborfreight.com/multi-use-rule-gauge-65339.html So is there some kind of technique or special angle finder to measuring the roof angle of the ports? Been searching the net and can't seem to find any specific how to's. I can measure the boost port angle with a protractor/angle finder with no problem because it is steep enough but, I haven't seen an angle finder that would get in the transfers enough to make an accurate measurement. Any insight would be greatly appreciated. . Quote Link to comment Share on other sites More sharing options...

edgehanger Posted December 12, 2013 Author Report Share Posted December 12, 2013 No. Im trying to raise my port timings and keep the exact same roof angles of the stock ports. As well as start to play with different roof angles and match all the port roofs so the angles are identical in the cylinders. Any suggestions?

edgehanger Posted December 12, 2013 Author Report Share Posted December 12, 2013 Make yourself a guage thanks. I been trying that since it was suggested to me this morning and its working. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted December 13, 2013 Report Share Posted December 13, 2013 No. Im trying to raise my port timings and keep the exact same roof angles of the stock ports. As well as start to play with different roof angles and match all the port roofs so the angles are identical in the cylinders. Any suggestions?You would not really wanna duplicate the stock angles for a couple reasons. First being that right off the bat, stock porting is obsolete and can be improved upon in any and every way not just heights and durations. The second reason being that if you in theory design the angles so that things flow a certain way toward the combustion chamber. Now if those ports are aimed a certain direction and you change those port heights and keep the angle the same it will be aimed toward the combustion chamber in a different way as it has not moved in relation to the ports. I couldn't tell you if your plan puts the angles of the ports in a better location or not though. But I doubt it will be all it's cracked up to be in your head.

Coupelx Posted December 13, 2013 Report Share Posted December 13, 2013 for his purposes stock angles will be fine. your theory is sound though. my stock cylinder had mostly stock angles and it was a running bitch. Quote Link to comment Share on other sites More sharing options...
registered user Posted December 13, 2013 Report Share Posted December 13, 2013 theres a real easy way to measure the angles. its not letting me post images or links. not sure if its on my end or what. ill try back later and see if it works Quote Link to comment Share on other sites More sharing options...

edgehanger Posted December 13, 2013 Author Report Share Posted December 13, 2013 Yea I get that @tricked. I think the stock port angles are aimed in ideal directions as far scavenging but, there is much room for improvement. I just didn't wanna raise the windows and have the directions all out of wack flowing in 8 different directions and creating all kinds of short circuits. I want to make both cylinders as identical as possible. For some reason the quotes aren't showing up Quote Link to comment Share on other sites More sharing options...
registered user Posted December 14, 2013 Report Share Posted December 14, 2013 pretty sure its something wrong with the site. quote wouldnt work. couldnt post links either. but anyways i just use a paperclip against cylinder wall and bend into the port then measure the angle with a protractor thing from the hardware store.

registered user Posted December 14, 2013 Report Share Posted December 14, 2013 for hell sakes. you just need something to bend into the port chanell. doesnt matter much what it is, hell some solder could probly work. look around the garage and see if you have something that can bend and hold its shape. some of you guys really over complicate shit. then most any protractor type of imstrument will suffice for measuring the angle Quote Link to comment Share on other sites More sharing options...
camatv Posted December 15, 2013 Report Share Posted December 15, 2013 the few times i have made some big changes i have actually just used the porting tool angles and based my flows from that. any major measuring i have had to do was done the same way.. with paper clip and measure from there.. just need to know where to point the charge and how its going to swirl through to the head design.
