What do you use for porting heads, and so on? I just like to see what other people are using.....figured it be a nice discussion.....I have the foredom heavy duty flex shaft txh-440 kit. the kit includes tx motor, hd 44 hand piece, cast foot pedal to have more control of tool and 10 piece bit set.... I also have a napa 90 degree air pencil grinder kit comes in a case with some bits and a in line oiler, I mainly use it for transfer ports on 2 stroke atv cylinders. but works great for hard to reach in corner ares as well...what do you use? I would like to see well known motor builder chime in if they would as well....

Cylinder Head Supply also known as Woodward Equipment has a good selection of tools. I buy a lot of "flame shaped" carbides, they are shaped like a flame or tear drop to allow cutting around a corner to leave a longer radii.

I use a Superflow flowbench, a set of flow balls and flags, I've got a set of petot tubes for measuering air speed. I've read a lot of stupid posts on here where someone was bragging about supersonic air speed....... well some people are clueless in the real world ans should best stick to fictional writing for entertainment purposes only. I've seen some pretty messed up port jobs and like Cody says, huge valves for dinkey manifolds and carbs. I've tested some fairley big name and expensive port jobs from around the country, I think some people pad their pockets and customers think spending more $$$ is better.

Shape is more important than size. Every "orfice" meaning port oe valve seat area has a certain coefficient of flow. The shape of the orfice or port has more to do with it than the size. The inlet to the orfice and the outlet will greatly effect how the individual orfice flows. The exit past the valve is verry important. If there's a chamber what can be done to help the air discharge into the cylinder or the exhaust discharge into the valve and port?
Most people should use their checkbook to poer their parts, if they really want to learn and do it themselves then find someone willing to spend some time on the flowbench and teach a little. Spend some time makeing the custom adapters needed to flow the parts and doing research rather than hacking away. Then learn a little and work on the parts.

I'll look at all the parts in the induction system and then start to figure out what can be done, what things should do and start to make comprimises depending on the given application and set of rules. It's not a perfect world and these tractor engines are far from perfect platforms to start with but the challenge is fun.

Burnuelis principle. Plan and simple. Amazing a fellow who wants to make profit from others would want more people to open their check book.lol pirot tubes or hot wire anometers do work quiet effeciently at evaluating the. averages to get a velocity the more readings more accurate the average becomes when transversing the porr.

A fellow asked a friend of mine at a pull this summer what he used to cut his tires. I'd imagine his answer would apply here too. He said "my checkbook". LOL

When I was probably fourteen I used an electric drill with a stone in it to polish ports on my dad's snowmobile.

What's a cartridge roll?

How can a end mill make a port flow?

Fogorn thats a good south alabama name . Lim has a good tn mountain name and is known for his math skills in figuring 5ths quarts pints and gallons . Lim decides he wants to hot rod a tractor he has been reading the hotrod magazines while in the outhouse . He remembers the test depression for a flow bench is 28 inches of water. He gets him some wire and makes a crude go no go gauge and realises the tractors port is smaller than the valve size of 1.5 inches . He remebers a neighbor saying he has a 1.5 inch drill bit so its lunch time. Lim goes into kitchen and while eating a piece of chocalate pie he starts scratching out some figures on a note pad . He takes the radius of 1.5 being .750 times it by itself again and gets .5625 times that by pie 3.14 while wiping the chocalte pie from his lips and gets 1.766 . Lim then takes the square root of 28 inches of water and gets 5.291 takes that times 4005 and gets a velocity of 21190.45. he takes his 1.766 and divides it by 144 for a square feet of .0122. he times it by the velocity of 21190.45 and gets 258.523 cfm . So he says hmmm if i get my port sixe to my valve size i can have a maximum flow of 258 cfm . He then goes to neighbor and ask to borrow drill bit the neighbor say shure but tells him its dull. Lim knows he can sharpen it on a bench grinder and can check the angle to maintain it by putting two nut flats together and the angle the bottom two flats give is close to the drill bit angle. So he tells the guy he will sharpen it for his use. Lim goes and gets it hung in the port and it breaks his fore arm so now the head will have to wait six weeks . During tha six weeks he stops on the mountain by a machine shop and they tell him a 1.5 end mill would be alot safer . Lim replies them are expensive ,the machinist replies probably not as expensive as the emergency room visit . Lim laughs and awiats healing up.

Quoting Removed, click Modern View to see Thanks guys . The name was changed but the drill bit roughing in a port is actually a true story . A guy who is known in this area for his ford 2200 dirt track engines does use a drill bit. he hasn't been hurt like the fellow in the story but has said a end mill is to expensive.It just added some color to topic. Dblair shop is staying busy not covered up but busy got to get that 440 inch allis done and to its owner. Yeap Ron your absolutely on track . The torque function comes from increasing cubic inches hp comes from improving airflow but wait increasing bore does both to a extent. see you guys when another funny shop story comes through.lol

Just remember that "Bigger" is not necessarily "Better"..! You need to be thinking "Air-Flow", in an Aerodynamic sense.. Study where high-performance heads are changed for performance.. Go to some Speed Shops, or "Head Service Shops" and ask to see some examples..

I hate to admit it but you are right, to a extent. The guy I go to (Jim Harrison) has a set of NHRA legal Chevy 2 humper cast iron heads that flow 100% more than stock. To be legal the ports have to be the same sq in. as stock. They also have one of 5 426 Dodge Challengers.(2012) I have looked at the latest Chrysler porting job. pretty neat. I know I am off subject.

Actually, I think you are right ON subject..!

Anytime you can spend some TIME, not money, and make your engine a better air-Pump, you are ON track..

That is about all an internal combustion engine is, is an air-pump...pump are more efficiently and you can increase RPM and that equals HP.. More HP at higher RPM allows lower gears, at the same ground speed, etc.. Low-end Torque is great "in the field", but Horse Power wins races and "pulls"..

Various sizes and shapes of Carbide rotary cutters get the major work done. I use the abrasive rolls, to clean up the rest. You can use longer arbors to reach farther with the abrasive rolls. A good drill will get it done, or you can use an air-powered Die-Grinder (or your flex-drive).. A GOOD performance Valve job will help as much as anything..after the porting and polishing is done).. More exotic ways are sometimes used, like an abrasive is pumped through the ports (extruded), to smooth and enlarge the passages, etc.. Ron..

cylinder head abrasives. www.ruffstuff.com. Get you a few long arbor rocks, some sand rolls & a good long arbor carbide burr. I also recommend an electric die grinder, preferably a Suhner brand w/ variable speed.

cody, thank's for the info. a good web page..... I always like finding a good place that sells all the dif porting and polishing bits instead of buying here and there....you know what I mean....
Kelly

some got off topic but I wanted to here what tools you use for porting.Its a learning curve that never ends.....there always ways to make power in porting all angles pay a toll smooth exhaust for flow, rougher surface on intake to help atomize fuel and air, everything makes things flow different and help or loose hp....

Boy I've seen just about everything come thru the shop. People get carried away & hog out a head then put a small manifold on it or put a huge valve over a small port. Bigger isn't alway better. A good smooth flow that isn't in danger of hitting water is what I usually go for.
