Revetec : “Or do they hope to overcome problems at a later date?”

Revetec knows better than anyone else.
Unless Revetec applied for a patent with all problems solved.

Revetec: “So how much more power?
It is now 5 years since the Patent was lodged on a camshaft design. The engine tacho shows it goes to 9,000rpm, so the engine is running. How about posting a dyno...

Regarding the GRECO I3 (www.pattakon.com/greco/Grecoi3.exe ).
It is interesting that the initial simple design used to demonstrate the parts of the engine and their interrelation during motion, was...

I have to thank the whole Revetec team for their work on Pattakon’s projects.
The only that worries me if their findings are not the worst flaws of Pattakon’s projects.
Please continue the good...

I spent a few hours thinking on how to “prove” I am not an elephant. I cannot.
I was surprised by the “level” of taik’s arguments.
If taik is not a real person, then he is invented by a...

CMC’s design seems simple but is not adequate.

They have thrust loads on the piston skirts: as long as the crankpin is at an angle (piston not at TDC), the double piston is supported by the square...

Revetec’s Law of Aspiration

“Any engine with connecting rod to stroke ratio more than 1.7 cannot breath efficiently. The only way is the supercharging.”

A good evidence, according Revetec, is...

Light version of Pattakon VVA on Honda B16 / B18 VTEC engines.

Why light version?
Cheaper.
Easier to apply.
Use of the existing VTEC system for the control of the exhaust valves’ lift and...

Initially I was accused for lack of courage to present Pattakon’s projects in an open forums (this specific thread was opened not by me, but to challenge me) and now I am accused for “spending too...

For the balance shafts, let the audience judge who is what.

From Revetec’s posts and mistakes I suppose Brad is not. Is...

The only thing I did not heard is an answer to my strictly technical questions:

Is the Boxer Revetec project phased out?

Is there a car with a Revetec engine for tests?

Are all hopes on...

Because Pattakon is in dept to nobody, it’s up to Pattakon to decide when and what to put in production.
Soon, I can say.

The VVA prototype cars are on the road for long time.
They are...

I copy Revetec’s complete initial reply to my first post regarding Pattakon GRECO engine:


Dear Manolis,

This company doesn't know anything about breathing. Any engine of this kind has a...

One of them can be the output shaft, too, as the ratio is what has been already...

A friend (thanks) sent me the following e-mail today:

I read the new (last two months) posts. Nothing...

Brad,

Just in case X4 is going to fit into this bike:

Brad,

Using push rods and side camshafts (how many camshaft? where located? how many valves per cylinder?) is not a step ahead, I think. If you can achieve good aspiration, high revs limit etc...

Brad,

As regards your plot:
Just think of going from a town at sea-side to a village on the mountain. Think how many times you use 4th gear or 5th gear in your gearbox (maybe none). Think how...
