Cool engine

I found this online the other nite read the link first  
Interesting way to make lots of torque. which all  ricers lack
All fabbed execpt for what appears to be a suby twincam set of heads

And here's a link to the dyno run  3 times the torque  never reved past 4200  do the math I can't but the fig are from 1350 cc

Holy hell i need that in my suburban:lmfao:

[EuroSS]

right ther"

and one more
heres the text to explain it

[cutlsp]

its a rotory engine:o

[EuroSS]

not really

[cutlsp]

wow to bad its not cost effecting compared to a 383 or something swaped into it:lol:

[EuroSS]

Well Speed cost $$$
how fast do you wann go

[cutlsp]

in a suburban not very fast i want lots of power to get it moving though;)

That thing is fucking awesome! It looks just like a scooby engine! I could easily fit an 10cyl version of that under the hood of the Lumina

shut up shut up shut up SHUT UP!!! THAT WAS MY IDEA 9YEARS AGO i though of that same consept back in grade 3,  but my dad said its useless itll never work GOD DAMMIT l foudn that sombody made this 2years ago l wanan strangle every person who told me l could never do it....but yet again mine works a tad differently and better with the structeral mounts virticly       anywho atlest l got my papaent for my design 6monthes ago a horazontil crankless all in one motor as l call mine

Heh nice a "roller" crank to go with "roller rockers". I can see how the would be usefull. However as with rotories I can also see where it would be problematic. But without the frictional losses of the bearings on the rods and using the rollers as well as shorter "stroke" Ill bet that puppie can hit 15k rpm easy.

[EuroSS]

with 3 power cycles/ a piston (6 for a pair? or 12 for this motor)? per rotation? it doesnt need to.

(quote from their site)
 "One module which comprises of a minimum of five  moving components, produces six power strokes per revolution. Increasing the number of lobes on each cam to five produces ten power strokes without increasing the number of components. "

so if you do the math? ?3 powerstrokes/cyl? ?@ 4k and change
the pistons are techincly? moving @ F1 piston speed @ over? 12.5k
part of the reason it makes more power

hp=  torque x rpm / 5252
 so if you spin it faster you can make more hp. within reason and that the parts can spin 2-5 times faster than a production part and no grenade

[Slims00ls1z28]

Ya but spinning faster also reduces torque so you really shouldn't need to take it over 4k but giving the way its made i bet it could handle the high rpm no problemo

[EuroSS]

no what im getting at is   it the oppisite of a rotary  where in those the rotors spin 1/3 crank speed so you have to wind them up to make power , the revetech spins the  the piston assy's  3 tmes crank speed  so the power is more tractable @ normal crank speeds

[Slims00ls1z28]

Yah I got ya. I could just imagine the maitenance on one of those though (one of my first thoughts in buying a car like my camaro I though oh shit changing plugs gunna cost me at least 3 skinned knuckles ) Alot more moving parts in the middle. But I'm sure if it gets a chance it will become just as reliabe as anything else out there.

[EuroSS]

NOt a lot of moving parts?, just 4? the crank, the 2 lobes, (counter rotating) and the piston halves (w / the roller brgs bolted to gether to make 1 part!)

I have a 2.5 limited gt scuby? and the plugs arent that hard to do ,just move the airbox? on 1 side and the w/w resevoir on the other.

Shit if you want reaally fun job? try doin an ls6 intake swap? on youre car w/o diconecting the fuel lines cause no fukin store around here had the godddamn tool and the back 4 bolt dont come out cause the too long ,

 HINT use old ladys hair ties to bind them together? 2 at a time, comes right out!

FIXED (mod edit)

[Slims00ls1z28]

Well I was looking more at 4 spinners per piston assymbly then the guiderods, bearing per lobe, bearings in crank, and whatever parts make the other lobe turn the opposite direction all that x2. Not really more than a standard V8 per se but I dunno its new and in this field drastic changes dont do too well at first in mass production. Caddy 4-6-8, CV trannies, all wheel steer, hybrid cars, etc. New tech (at the time it was new rather) but none did too hot in its first inception. Same reason I'd never buy a brand new car ( new design/platform not just 0 miles). Scratch build designs always have bugs to work out.

As far the LS6 goes though when time comes for it to pull the intake it will be in another car and a built LS2 will be in its place

Looks like a combo between the Mazda RX7 rotary engine and a radial engine from an old plane or something.  Torque's not that hard to come by in a small package nowadays... example, Ford's 4.6 SOHC (281 cu.in) bored and stroked to a 337... and Edelbrock now makes a Victor Jr. intake for use with a carb or DPI system, plus all the Paxton and Vortech goodies out there, aluminum heads, etc.  Then you start talking 5.4 liters but the horsepower adds some serious weight.  But that's just my opinion being a Ford guy.  Maybe this motor they're developing will have some good fuel mileage and they'll start putting them in cars ???

(and camaros still whoop them)

[streetboss351]

Kinda depends don't it ???  When you're loaded, you can make anything happen.  Those modular Ford strokers are pretty tough to beat...
