I’ve heard of a flat fanned, 4 valve per head, 8 cylinder motor coming together for a coachbuilder that’s Porsche adjacent. More of a Porsche evocation than a “re-imaginement” and would be evoking a mid-engined Porsche not our beloved 911. Believe 1 and 1/3rd of a case coming together but you’ll tell me if that is impossible. Certainly doesn’t seem like it would fit in a 911.
Next year marks 40 years of the 959. Can you build a better 959 motor? |

How about an Eaton 1.13L Roots blower.. If you did a low boost engine you could forget the intercooler or a 1bar engine and make 350 PFT at 1000 RPM. Now you might need Corvette half shafts.

What I said was driveability over "cool factor" is counter-intuitive. |

"Buy new parts" Oh, OK I don't need your advise about how to build air-cooled Porsche engines. This thread was about "what built formula" would be cool so I could build it on the forum and auction it when it's complete. |

You asked for suggestions and I gave mine without any sort of wrong intention. Merely suggested that maybe consider looking at creating new parts for customers. Even said you had a new Camshaft that was successful, so build on that and offer more. However you read my post I cannot control that. Good luck with what you are going to do. I wish you the best, |

My head is not always in the most receptive place. I am constantly looking to design and build new parts to keep these old lawn movers running, so I appreciate the encouragement. Cheers |
No apology required. We all miss read things at times.
Looking forward to seeing what you come up with. The more of us that do this and create a better mouse trap the better for all. Go to work. |

I've built literally hundreds of driveable everyday tedium....This project was intended to allow people to get creative. |
The last open ended project we built.
964 based, 3.8, Slide Valve, Motec street motor designed to retrofit in an early chassis. http://forums.pelicanparts.com/uploa...1749681676.jpg http://forums.pelicanparts.com/uploa...1749681676.jpg |
Well after 400 engine builds you have done every internal trick and combo, so that leaves the outside sub systems to customize. Fuel, air, ignition, cooling, exhaust. How about a Vortech blower mounted where the AC compressor was.
|
How about spinning the fan faster and bleeding some flow to make a low pressure blower.

There are still engine designs that can be explored. let's get creative with engine designs not bolt on ancillary gimmicks. |

Those high RPM fans were generally on low RPM street motors. Porsche even reduced the fan diameter and the crank pulley diameter on race motors to compensate for fan tip harmonics that created a cavitation. |
6 more cylinders.

Once again, let's come back to earth with your suggestions. I'm an engine builder not the tooth fairy. <iframe width="560" height="315" src="https://www.youtube.com/embed/fRDMx3-nhgY?si=LmpU5NRr05WAkTUF" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe> |
What seemingly started off as a genuine open discussion seems to have been a thinly veiled attempt to start fights.

My suggestion would be to stick to the thread intent. Make suggestions about what might make a cool engine that Henry could build while we watched. I'll start. I like short stroke engines: Let's shoot for 9K on 91 octane. 66mm x 100mm or more? Titanium rods Lightened crank Forged rockers Super light pistons with 21mm wrist pins Is there a way to make 2 valve cams adjustable? I've seen something you call Venti-port. Will that work with high rpm engines? ITB with open stacks like Singer has used in the past. Will your super short Supertec headers work with such a build? Twin plug of course. Can a 3.1 SS make 350 hp on street gas? |
