Golf Ball Technology in Diesel Engines

Dimpled Pistons Use Golf Tech to Improve Diesel Power, Efficiency

Speed of Air claims their dimpled pistons make more power and reduce particulate emissions of diesel engines, and have the data to back their claim up.

Cool! The HEMI of the modern diesel era.

well if it's good for diesel, has to be good for gas !! ?? yes, no ??

Magic foo foo. Painting flames on the side of your truck makes it go faster. Bigger rear wheels save gas too because you are always driving down hill.

The many little inverted hemis.

Interesting read. The latest in people trying technology to get more out of the old engines. Anyone remember the company that sold the metal inserts that went in to your air intake to make the air swirl in a vortex as it entered the combustion chamber? I could see the dimples working just a bit better. Better fuel air mix/suspension, better compression and better HP/ emissions.
Now who will be the first to go out and drill their pistons on their Orange to experiment?

Mythbusters did it to a whole car body and it improved gas mileage

for those of you looking for quick HP gains, remember painting your calipers red is good for at least a 10hp improvement

Sooo…. all I have to do is … drop a ball-bearing down the plug-hole …let ‘er run a while…..

Maybe taking a ball peen hammer to the body panels will increase MPG also?

they still do ! came out of a 2001 F150...one day I may install in my '97 F150

The best way to get maximum power is to increase the amount of air/fuel passing thru the internal engine at the fastest rate possible. This would be an axial-flow/ram-jet such as the SR71. No golf-ball dimples on that one that I observed in the times I’ve had hands-on it… oh…wait… what’s those little holes at the aft containment-ring…? LOL

couple somewhat well-known cylinder head porting guys have found some success in "golf-balling" the intake ports. But it comes at a cost. 15hp for another grand worth of work. The majority of people don't go for it and I don't blame them, when you can make 15hp for a lot less money.

The extra HP would be 'FREE', if they didn't spend all the money on useless, unneeded 'electronics'.....

My car has four less cylinders, more than twice the horsepower and double the mpg than the old man's V8 Model A. Electronics had a lot to do with those improvements.

Race engines are dimpled on the intake ports all the way to the butterfly. Intake valve to on the port side. Really not too hard to do and does not have to be any CAD alignment. Just touch the burr a lot. Adds 15 minutes per port and valve.

Adding golf ball technology seems to be a great way to attract water into the cylinders….

Found water with a lot of golf balls. Good thing I gave the game up.

Sorry for the tangent on diesel engine construction....

I've "witched" water well locations quite a few times. My Grandfather taught me.

Just used a small forked branch from a tree nearby.

My Grandfather recommended apple. I practiced on our farms 50 years ago.

Friggin' thing would "point" to spots....

One of those I witched now produces the water to my house, and 600 other connections in my village. Capacity was estimated at 2,500 gpm, but designed at 500 gpm or so.

I'm a scientific person. Don't believe in it, but it's worked multiple times.

Go figure?!?!

What they found was that dimpling does 3 things. It causes more surface area in the port, leading to "skin friction", it gives the port more places for cracks to propogate, and it "can" allow more power-although the gains are typically not really worth the R&D it takes to get it right. There is a reduction of "base drag" or "base friction" but the percentage of CFM and horsepower improvement was not significant enough to warrant mass production--at least not at the level we were messing with it at. Some guys wanted it and so be it, we did it for them and it cost more. Similarly the guys who were using Jager's connecting rods, they wanted them and they paid (dearly) for them. There wasn't enough advantage to justify the troubles. Then some things got "outlawed" (sanctioning body rulings), in order to "control costs" which usually works the other way in professional racing. They just find more (and often more expensive) ways to bend the rules.
