My new piston 3.0+

[faapgar]

My new piston design is about to arrive.Developed in 1997 I had Mahle make 5 sets of the prototypes.CP just made 2 sets off the prototype mold.Patent is pending.The best piston design for a 911 ever.I have a second version in process.More power than anyone else has done before.The early version was in a 2.8 built on a Turbo case.66 stroke by 95mm bore.Used special 3.6 early heads that the stud spacing was narrowed and done by the best drag racer in the North East.Heads flowed 326 cfm.Port size was not changed much but the devil in the details.The motor made 373 hp at 9300 rpm.It MADE TORQUE from 244 ft.lbs at 4400 rpm-249 ft lbs at 8900 rpm.They will come in the nest day or so.I will post pics.I just waited 22 weeks for these sets.I am lucky I am 71 and my 2500 sq.ft.shop is paid for.Tough to be in a business with our current supply chain.I have made 95-98-100mm pistons.Due the design and shape these make 20-35 ft. lbs. torque from 4000-6500 rpm.Coming soon.Ciao Fred

Fred - Sounds terrific. Congrats!

[Jeff Alton]

Cool, congrats. We did a similar project for our M96/97 pistons.

Why don't you explain to us what makes this the "best piston design for 911 ever" and show us the supporting data? There is much more in that motor you describe than the best piston to create the power you claim.

Would love to see pics of those 964 heads with the narrowed stud spacing as well. That is cool.

Looking forward to hearing and seeing all the details and supporting data.

Cheers

Do you have a video of the 2.8 revving? Must sound amazing when it gets above 8k!

[faapgar]

Looking forward to the pics Fred, after our recent chat I have a picture in my minds eye of what they look like and more importantly why they work. Richard

Fred,

Its great that more new products are coming for these older engines. There is no reason development should stop. The more that get involved and offer alternative options the better for all.

Good job my friend.

Pics in the next two days with an explanation why they work.Thanks Fred

I would be interested in a set of Fred pistons, are you selling any sets? Or have an agreement with any manufacturers or are these just personal use?

Fred,
Looking forward to learning more......

I am waiting for the UPS guy or gal to show up TODAY and make me smile.These will be available for sale.Long wait from CP is the downer though.These 1st two sets are 98mm.One for 66 stroke and 70.4 for the other set.

[blue911rsr]

What length rod and what pin size

[faapgar]

The wrist pin size for these is 22mm.For motors with aftermarket rods 19mm will be offered.On 66mm stroke I use a 132mm rod with 98mm bore for a SS 3.0.Still waiting for UPS to come today.

I got my 1st smart phone a month ago.I got a text picture of the piston last week I just found.So I took a picture of the picture on my phone to give you something to look at.

[faapgar]
