Probe pistons

I'm looking to put together a backup engine and need 2 Probe 14792-80 pistons. If I cant get Probe maybe I'll substitute another brand. These are 80 over flat tops with a .990 pin 1.350 CH with intake relief for SCJ or P51. I will take used and buy more than two. I didnt realize how heavy these are but it'll only spin to 6300 when I'm done.

Might be able to get them new again

How is that possible when Probe is gone?

Mark uses Ross to make his pistons.

And others besides Ross.

I though that was the guys he sold the parts and building business too?

"Coast High Performance" was sold to Custom Performance in Gardena.

I have that, and I still have Probe. Sold CHP.

Racetec will make singles......eventually. As long as the compression a weight are the same, you're covered.

Thanks for the information here.
Mark- Are the Racetec pistons your old forgings? Also you have them on your Vigilante site why not sell them direct?

No. Everyone has their own forgings......and they were all fighting to see who could be cheapest. Wiseco and Mahle won. I do sell Racetec direct, I just haven't put them on the site. Frankly, the profit margin is low enough that I'm in no hurry. That, and I learned everything there is to know about a little guy competing with multibillion dollar corporations. If you have the opportunity.....don't. Between Mahle, Wiseco, and Edelbrock........

The ones I have made for me are on my prints, and I have a lot of combinations that they only offer as customs.....and I only use the Autotec for the SRS Series. The PRS are made by ROSS, again, off of my prints. I dropped the FPS, altogether.

I also have a couple of guys that say they want to buy the name, designs, and programs....but we'll see.

Mahle is THE world's largest piston company. CP has probably eclipsed JE as the top custom manufacturer by now. JE , Diamond and Wiseco are all under the Race Winning Brands "umbrella" and Wiseco is the smallest though they do forgings for the other two. Wiseco does more power sports business than automotive business. Racetec /Autotec was never meant to be a low cost piston .

I doubt Wiseco's forging plant can keep up with Wiseco, never mind Wiseco, JE, and Diamond. Pretty much everyone buys from APP....and there are two other smaller players (stateside). CP has some really solid OEM contracts. I think Performance takes a back seat to that, but that's just opinion.

Wiseco makes pretty pieces, when you can get them, though.

I just got my PRS slugs last week Mark and they are awful pretty too!

JE and Diamond have converted to Wiseco forgings. They are not using APP any longer. CP , BME, Racetec, and some others use APP. CP and Racetec also use Performance Forge.

I should have shot pictures of those.

I'll send you some pictures Mark when I get them back from the machine shop.

Thanks. I'd appreciate it.

That OEM/AFR valve relief came out a lot better than I thought it would.

One single , large , fit all relief will certainly look better than "dual eyebrows".

How many CCs in the intake relief of the 'dual' piston?

How deep?

It's not nearly as large as one might think

.310 with w .375 top land. I haven't done it on a flat top yet, he had a dish. I'll have it in about two weeks. I think it will end up at 4 ccs.
