diy V12

Post by ProstheticWeasel » Sun May 12, 2013 9:38 am

Saw this http://www.foxnews.com/leisure/2013/05/ ... p=features" onclick="window.open(this.href);return false;

To sum up guy takes 2 v8 engines cuts them up and makes a v12. Apparently they have several successful ones already and this one is from the parts they had left over. The crazy part to me is that they cut the cams and crankshaft and connect them back together.

I'd love to chop a C4 Corvette at the front, and another length of engine bay, and build a V16 :clap:

They've dropped one into a Suburban, and another into a 3/4 scale P-51.

More info can be found here at the LS1 forums. Pictures of chopped heads, crank, cam... I give these guys mad props for their ability to make this work. The thing that stands out the most to me is that they cut the cylinder in half. Measurements, and the cut, have to be exact to maintain roundness.

They also built a V4, because, why not.

The first V8 engines were made by putting two inline fours together on a custom crank case.

The Kawasaki 500cc two cylinder engine is the outside two off of a 1000cc four.

So it's not a new concept, just new parts.

Neat project. If I were doing it I'd probably start with two inline sixes... or would two straight eights be better? :twisted:

Weren't the first generation GM V6s made by chopping two cylinders off a V8?

In effect, yeah. I don't know if that's how they deigned the 90* V6's, but a lot of the internals are interchangeable with the V8's.

Same with the Cummins 4BT and 6BT. I think the only difference between those is the crank and cam.

Yep, but it's still pretty cool. Way beyond my abilities/patience. If you snap the crank or the cam shaft I think you're pretty well toast though, since these are one-of designs. According to the LS7 forum posts, they're still developing their process, and this one is intentionally being put together differently than the others they have made.

Chevy made a zr12 concept vette back in the day. Fit it in a nearly stock engine bay too.
