Nitro Style Piston In Alky Application

Was looking at some really nice Venolia nitro piston blanks awhile back, and was kind of impressed by the design. Stout, ready for a 1.156 pin, enough crown material to form the top profile that we want, and basically an economical shelf item before custom machining.

In an extreme boost 10K+ RPM alky application (4.375 bore), any thoughts good or bad, regarding: 1)the extra piston mass versus a more standard alky piston, and 2)hard anodizing the entire piston after final machining like the fuel guys do?

Thanks.

 

Coating

I machined the tops of my A-Fuel pistons for use in my blown motor. Because I couldn't sell them @ a honest price. Have 3 sets, I run Brad 5's. and a roots. JE say,s the reason the top is coated because it is cheaper and easier than just coating the skirts. If you can machine the dome like you want,at a good price. I would say go for it. Just remember the pin end it is wider on a fuel piston. You will need rods for that piston. I have 3.30 pins from Bill Miller. They weigh a hefty 329 grms. So the pins are heavy, my piston is 813 grms. Really heavy compared to a blower set up. of say 700+ grams of piston, and say 225+ pins. because you can run a narrower pin.. Hope that helps a little.

Aloha TOL
Do you by any chance have the Arias piston # for the 4.375 bore, I've been to thier web page but never saw that there was a shelf piston for a Hemi with a 4.375 bore.

Where can I get 4.375 alcohol pistions to fit my AJ stage IV heads? Big pin

 

see above post....that is what i would put in your motor. i think BAE will have em on the shelf. ask them about that part number.

Thanks, I had went to Arias' website and they didn't have those listed. I'll call BAE.

 

Hi James, Eric Gates here. You may remember my Dad, John, from the old SCEDA days at LACR. I just bought those exact pistons from Arias. You can't beat their deal. PM me if you want to know more.

 

I will never forget your dad. Him and I were getting real close. One on the best guys I have ever met. . Lets light that beast off James!!!!

 

Hi Eric I remember your dad. Meeting him was like meeting a friend you haven't seen in awhile. I was testing at LACR (1st time there) pitted next to you guys and had a pump problem. Man you guys went out of your way to help that day, thanks again!
