landman Posted February 12, 2017 Posted February 12, 2017 This was made out of two Mickey Thompson 389s.
wayne swayze Posted February 12, 2017 Posted February 12, 2017 Nicely done Pat! Fits in well in your diorama. Was there ever such an engine in real life? Never heard of it before.
Dann Tier Posted February 12, 2017 Posted February 12, 2017 This is Extremely cool!!!!!!!!!! -killer diorama!!!! Q: where did you find that forklift?

DumpyDan Posted February 13, 2017 Posted February 13, 2017 Awesome V12, you should drop it in something

Ace-Garageguy Posted February 13, 2017 Posted February 13, 2017 Pretty cool, but if it was real, you'd have a very complex balance and even-firing-pulse problem to solve. A V-16 on the other hand...

Eric Macleod Posted February 13, 2017 Posted February 13, 2017 I think John DeLorean would have called in Zora Arkus Duntov, who would have been up for the challenge! Great engine and I'm loving the evolution of the diorama.

Ace-Garageguy Posted February 13, 2017 Posted February 13, 2017 (edited) I was thinking about that. Most V12 are 60 degrees aren't they? Yes, that's it exactly. When you build a V6 or V12 on a 90 degree angle, the only way to get even firing pulses is to stagger the rod journals on the crankshaft (exactly what GM did with the "even-fire" 231 and 252 cu.in. 90 degree V6 engines), and though it's not the best solution for a high-revving, high power-output engine, it can work just fine. The "odd-fire" 225 cu.in. version of the engine uses a very heavy flywheel with unique balance characteristics, and has a unique exhaust note. The Chebby 200 / 229 / 262 90 degree V6, essentially a smallblock V8 with two cylinders missing, used an odd-fire crank, with special flywheel balancing and "softer" mounts, and eventually an internal balance shaft to deal with vibration and rocking. Anyway, it's theoretically entirely possible to get a 90 degree V12 to work acceptably smoothly (a couple of different ways, actually) and nothing would show from the outside.

espo Posted February 13, 2017 Posted February 13, 2017 Beautiful engine. Mickey Thompson would be the person to do this in 1:1. I remember when he cut one of the 4 Cylinder engines in half for a 2 cylinder and latter even tried a single cylinder. You never wanted to tell Mickey he couldn't do something. The guy would just go out and prove you wrong. You really should build something appropriate for this engine.

I had bought this as a special car show vehicle that FTB could use to haul and display engines. Perhaps it would be a good place for that engine, it being a Pontiac and all...
DumpyDan Posted February 14, 2017 Posted February 14, 2017 Great idea, there is a lot of room under the hood. I have this car started, I put a roof from Buick GSX didn't care for the Convertable.
geetee66 Posted February 14, 2017 Posted February 14, 2017 That engine is remarkable! I'm right into dioramas at the moment. Looks like you've constructed a very detailed and interesting scene, there.

Bernard Kron Posted February 14, 2017 Posted February 14, 2017 Super cool idea and execution. It serves as an inspiration to me for the Engine Build-Off on the TRaK board. Fantasy engines are always Big Fun!
