1500cc, 100hp@6500rpm!?!

Thank you Zen. Yeah..I see the trick... Although I've found such an engine for 5500 USD. Not that bad if you consider Rabi prices... But you've got to a damn good and patient macanic to play around those engines: to tune the four cams it takes up to 15 hours!!!!! Let me tell you; you don't change them every day. Another reason you get so much power is the 2 sparkplug per cylinder: better fuel efficency. I was wondering zen (or anybody) do you know if that's what the Apfelbeck project's all about: 4 head cams?

I have seen 1600cc T1 motors that make 140HP.
Its all in the heads and the compression of the motor.

Only 2 cams for the Apfelbeck Project, one for each pair of heads.
2 inlet valves and one exhaust for each head should make them able to produce 115 HP/Liter..

What's the project completion date now,haven't heard anything on these heads in a long while. Have you guy's given up.

No completion date yet...

We all have full jobs and a personal life as well

We will get this project finished, but we won't rush it.
The original plan was to go for a "one off a kind" engine. That would have been way easyer than to try an make it into something that can be built in small series...

We will finish this project as fast as our spare time AND our budget allows

The 547 4 Cam Carrera engine had high CR (11+:1) and a true hemi chamber with twin plugs and incredible RPM potential. These engines make wortless power on the street as I have driven this one http://www.aircooledtechnology.com/p...era/index.html
When I had it here for repairs a couple of years ago..

These engines run about 75K to REBUILD STOCK.. They don't make any power below 5K RPM and they are very finnicky to tune...

Here's Brent and posing with an Abarth tuned 547 from a 59 Carrera GT that raced at Leman in 1960

How about magnificent for an adjective?! What kind of type one would give a similar feel? In term of performance. 1911? 'Cauz it's basically a T1 right? T4 did not existed at the time...
