TOM J from Arias:

Arias , JE, Ross, Wiseco and Cp are all made of the same material either 2618
or 4032. Arias, JE, CP, and Ross use the same forging house to make all of
the forgings. When ordering custom pistons you need to be specific of what
you intend to do with the pistons. All of us, piston manufacturers,
over-engeneer all of our pistons so we have no piston failures.
This is why you get heavy shelf pistons.
Some one may say that they are going all motor and then they put NOS on the
motor and now you have a failure, the customer now says he has a bad part
when he never his intention to use NOS.
This is how piston companies get bad names. As for an employee of Arias and
a motor builder I prefer to use Arias. Arias has been using there own product
for over 35 years no other piston company can claim that.
Keep in mint that Mo from ross used to work for arias that is how he learned
to build pistons. Same with Tony and most of the engineers from JE.
Dave calvert and all the brothers from CP also learned to build pistons from
Arias. So when you ask who has the most piston knowledge,
Arias has by far the most and will continue to be the leader in sport compact
pistons.



Darius Tarman, from CP Pistons


CP Pistons has no rivalry with Arias, or any other piston company.
I’m replying to this post to give CP a voice in this discussion.
This is my first post ever on this board and I don’t want to be drawn into
long rebuttals.
CP uses a variety of vendors for forgings, some of our vendors do not supply
piston forgings to any other company.
Every one of our sales personnel has assembled engines and raced cars in some
kind of format.
We have been in business for just 6 years, but the Calvert brothers that
started this company together have a wealth of experience spanning over 85
years combined.
All of our sales personnel and a huge portion of our machinists came from other
piston companies.
Moe Mills is the owner of Ross Pistons and he used to work for Arias, along
with the Calvert brothers.
Moe broke off from Arias along with another employee to start Ross.
He left Arias to make a different piston, not the same pistons he had been
making. Dave Calvert left Arias more than 14 years ago, and has been in the
piston business for 32 years,
this is not counting his brother’s experience.
Just because you took auto shop in high school doesn’t mean your teacher can
take credit for everything you know about cars now. Arias himself used to work
at Venolia. So is Venolia the undisputed king of pistons?


I can assure you that I, along with the rest of our sales crew did not leave
a job at a piston company, for another piston company to make an inferior part.
I don’t mind if a shop is comfortable with a certain brand of piston or
product. But you can’t claim it to be the best unless you have tested them
against other brands.
Not breaking is the first demand most people have of a piston,
our customers require that along with more power.
I don’t want to sit here and right a long list of the all big names we build
pistons for.
Some of these names run other brand stickers on their cars, that’s up to them,
they paid full price for their pistons.

We have an awesome inspection room for all our high-end stuff (Nascar, IRL,
etc.) We have the equipment and programming to measure all the dimensions.
I’m more than interested in an independent test of our pistons because
I already know the results.
Nobody needs permission from any company to do this test,
grab the pistons and go inspect them.


TOM J from Arias:

Darius you seem to know very little about your piston history.
Let me help you out.
In 1953 Nick Arias and Bob Torros rented a small shop from Frank Venolia who
was a die maker for waynes chevrolet. Venolia was not a business at this time.
Early 1953 Nick Arias and Bob Torros filed for a business license in the name
of Venolia pistons. A few years later they took on a partner Joe paisano.
Together they made Venolia what it was.
In 1967 Nick decided it was time to do his own thing.
So this is how Arias became a piston manufacturer.
So if you need some more piston history feel free to ask Tom Jung.
I will post some pictures of the Venolia and Arias history for all to see.
