JClark, drool inducer for ya.

Who invited another nerd?

:rofl

just kidding, but seriously who are you and where did you come from?

I like the dual exhaust manifold setup on this one, is this for easy N/A –> F/I conversions?? :retardclap

:smiley:

+1 , Who is your daddy and what does he do?

More extremely knowledgeable people on this forum = more reading pleasure for me and everyone else :smiley:

I was referred by a friend.

I want in on the next Go Kart event. It’s going down.

I know a thing or two, enough to get me into trouble. I’m there are other people on this board who are just as well educated or better.

I signed up here specifically to comment on this rod and piston design.

john, whats up!:happy:

I know no Peters, especially none racing at Lebanon valley.

Benny, don’t be jealous now!

1320-20V…send me a private message(so you don’t have to expose yourself to the masses here, hahah! ). Also let me know who referred you and where from, it’s nice to know where the word on this traveled to :slight_smile: Credentials/past experience? I’m not discrediting your knowledge at all, rather I’m actually looking forward to speaking with someone on your level and possibly bring you in on this project the future. I’m intrigued by your interest in the project itself and you adept knowledge in the field, and am always open to someone input and knowledge on such an applied subject as this. On a similar subject I’m am going to need to speak with someone adept in thermal analysis, more in tune with cylinder cooling and expansion rates of given materials. If you know more on that subject, you’ve just been bumped to the top of my “need to be-friend” list!

You right in that I modeled those renders in SW myself. The piston design is an exact duplicate of the BMW S54 piston(aside from piston bosses and pocket). I made that model specifically to send to CP, Ross, and Mahle for review and quote inquires versus just a standard tech sheet and kills two birds with one stone. CP and Ross came back with positive notes, however I couldn’t meet Mahle minimum production requirements. My intention was for them to take their proprietary forgings and mate them with the stock compression height, valve reliefs, etc in the CAD file so I didn’t waste too much time working up the bottom half of the slug.

The rod render was also developed in solidworks, using base OEM S50 rod dimensionality but not taking into consideration all the implements you mentioned. A few things were changed from the original rod(beam design for example), but only merely as a visual impact on the render knowing that the rod manufacture would dictate everything else. I knew exactly what rod length and other various dimensions were required and made the render for use in further renders(crank, case, etc) so that I could further test the feasibility of the engine as a whole. Overall package size, complexity of sub systems(timing drive components mainly) My intentions for that render were the same as the piston, however to send to Arrow for their engineers to interpolate the required dimensions into their own developed forgings(subsequently, Carillio and Pauter as well just to have options) Arrow is also likely going to be the outsource for the crankshaft design and manufacture, but that could change.

What makes this somewhat relieving at the moment is basing most of the workings off existing BMW engineering, currently used in their M series cars(S50B30, S52, S54B32) so overall workings are laid out in general. Rotating assembly structural analysis and finite design I’m leaving up to the specific part manufacturers to complete. Just the right/smart thing to do, and takes the load off me of having it done elsewhere. Working out order vibrations and balance for later( v12 makes it easier as they’re canceled out).

I’m known here for my long-winded tech posts so I’ll stop here and wait for your response and/or PM before continuing further. If you’d prefer to contact me offsite, send an email to R247Motorsports@Gmail.com. Title S70-3 to keep it out of junk folder.

Look forward to speaking with you.
