take a look at this engine

[cammeddrz]

how does it seem weak? 664 lb ft of torque at 2100 rpm doesn't seem to weak to me

mechanically dude.......

He doesn't mean weak in terms of power. He means weak in terms of how it's built. 12"+ connecting rods attached an inch or two to the side of the piston is just asking for trouble. Not to mention the lube and gravity problems all horizontal engines have to contend with.

oh gotcha

I cant really see the engine well on the site,Im on dial up so I can to video. From what I gather from what you guys are saying the strength may not be as much of an issue because of the low rpms. I never thought I would hear of a V-16 spinning 19,000 rpms or a pushrod V-8 spinning 9,000 rpms but they can. Materials have advanced so much it's nuts.....like a crankshaft made from carbon fiber in the new Mercedes V-8...I didn't think that was possible.

 

[rangerluver]

now he has a point there. Put in quality materials along with the lower rpms and it seems that you have the torque of a diesel with the power of a gasoline motor. Best of both worlds it would seem.

Besides, they make formula v-8s rev to 20000 so these are quite low in comparison.

a formula v8 has such tight tolerances that it needs to run a double-zero weight oil (that's thinner than atf, in fact that is closer to the viscosity of diesel fuel) and even then the engine is literally siezed when it is cold so 6 block heaters are necesarry to loosen it up enough to even crank over. and the entire engine gets replaced after every race

yes metallurgy has come a long way but if the formula enginges are any indicator.....this thing may not be streetable enough to put into a car

This new engine does not need the high RPMs is what I'm saying so strength isn't as much of an issue as it would be even if it was spinning 6,000 RPMs. I would like to know more about this engine but I cant really view the website.....dial up dont pull enough revs lol I have wondered about something but I don't know if it would even be possible....imagine how many cubic inches could be had out of a normal sized engine if it could made with square pistons.

honda tried a variation on this in the 80s,but it was oval pistons.the idea was to get around the ruling in moto gp that you could only have four cylinders.so they made what was essentially a v8,but cut out the block between pairs of cylinders and had an oval piston with two rods on each.

as you could imagine,getting the rings to seal was an ongoing issue and the idea was discarded.

High revs are key with this engine. The guy even says one of the primary benefits is with two pistons per cylinder each piston travles half the distance (stroke), which enables higher engine speeds. Paraphrased of course, i'm on a cell phone here.

Dad has a 321CI (5.50 bore x 6.75 stroke) two cylinder, I have a 175CI (4.50 bore x 5.50 stroke) two cylinder. They are horizontal inlines too.

They are low compression slow turning buggers, but they run forever and are scary easy to work on. That is what was fashonable at the time, it is crazy the power people are getting out of them now playing with the heads, carburation, cam, stroke...
