oh my lord this is perfect!!!!

[n12frost]

hey check this out some major power up grade and say some serious rpm. although not into production but if i had enough dough i would seriously take it into consideration. no valve float better economy less emmitions..*droool*:bow: http://www.coatesengine.com/

[n12frost]

quote from coates.. "Equipped with the poppet valve head, the Lincoln engine dynoed at 260 hp and 249 lb.-ft of torque. When equipped with the CSRV head at the same 5,500 rpm test protocol, it made 475 hp and 454 lb.-ft of torque, with no changes to the block or rotating assembly" i can only imagine the power my inline 6 would make just by changing the head..mmmmm yumm..:firehop:

oh yeah, lets do a group buy! Hooray!

Lets see..interest(BS)√$(R3V)=11 people with more than $100 to their name

So, with developement costs at about 2 gazillion dollars, this should be affordable in 2132. We should get Meric to make us some! (r karz woll ned bug brraks)

Seriously, that is fucking cool. Rotary valves have been around forever, but never gonna happen. A bunch of solenoids popping open poppet style valves is so much cheaper, plus this is Amurrika, so we like things that go up and down more than round and round.

Wish I were rich.

i cant get enough this is anouther quote..."Since horsepower is defined as work over time, the CSRV allows for an extremely high rpm potential. Test run at Coates' facility have seen a Ford 5.0 liter engine spin to 14,750 rpm! Though the CSRV removes the valvetrain rpm limitations, the need to have a rotating assembly that can withstand the engine speed becomes the essential element. Another benefit of this design is the extended oil change intervals, with the lubricating system not being exposed to the rigors and pollution from the poppet valve."

HAHAHAHAHAHAHAHA.

I was able to do that complex calculation because I attended school in California.

Luke you are on a roll today.

Hahaha BUUUUG BRRAJEAKz. All yuour bumbners are bleong to us.

[n12frost]

yea only if we had LOTS of money to spend freely. 15k to start on anyblock set up and they will build one for you. although it sounds great i will rather wait till its more widly used to save money. i almost want to invest in them because if it does get used world wide its going to be huge. it almost solves polution from the current motors we use.

lol, not too bad either.

The only problem this head design has is the ability to apply VVT.

This is where EVT beats a RVT. EVT = IVVT (Infinite Variable Valve Timing)

[Rennsport]

so what happens at 20k miles on the head... how well does it hold up to carbon build-up?
(i did not watch the video, cuz im at work and i cant do that here... so if that info is in the video, i apologize in advance)

[StereoInstaller1]

how well does it hold up to carbon build-up?

My understanding is that the carbon build up is primarily caused by oil leakage down the valvestem.

According to Coates, there is no lubrication required on the top end.

I imagine there has to be some blowby on the rings, but if those valves rotate, not much is gonna build anyway.

Rit makes an interesting point...no VVT. One of the main reasons I want a bunch of solenoids popping poppet valves, like MBZ planned/prototyped back in 2001. Talk about CVVT!

A buddy and I were talking about this very idea, any more info about this prototype engine?

[Fidhle007]

Y'all got it way wrong. The flux capacitor is where it's at yo!

Seriously though, this sounds like an awesome idea although I'm sure it will be a long time before it catches on, if it ever does.

Nah...read about it back in about 2001 in something like "Popular Mechanics" in a doctors waiting room or something.

Variable lift is do-able, but way too much hasle. Variable timing and duration would be infinitely variable. Smooth idle, rowdy power on top. Wewt!
