Orratech twin plug type4

Rough translation from German,

Trial of a dual ignition Typ4Motors ORRATECH 2.5 L engine, Limbach-
Cylinder heads Willibald / Richertgebl

Interesting, not sure about the Corvair pulley system but the thing I did notice is that it still sounds like a VW engine

Maybe so, but to my ear that thing sounds awesome!

It's a pain in the ass enough to get to the 4 plugs I have let alone doing 8!

In ref to the "Corvair Pulley" fan belt. I drove a Corvair over 250,000 miles. Early on, I blew the fan belt off twice - within five minutes of each other - coming DOWN a mountain at 90 MPH. Switched to a Gates "cogged tooth" belt. Never ever had another problem after that.

Twin plug, big bore TIV engines rock.. My record is 283HP N/A on pump gas from a 3 liter TIV twin plug with EFI.. I did that back in 2008.

See the July 2000 VW Trends for a story on my first twin plug TIV.. It took me the better part of a decade of development to optimize head preparation, plug placement and camshaft optimization.. The design of the engine is critical to the efectiveness of a twin plug arrangement.

Do a search on the spyderclub for some really dramatic exchanges concerning twin plug engines between Pat Downs and I.. It was a pretty childish exchange, but man at the technical information that was spilled over the argument..

ORRATECH...Never again, that's one of the worst address in Germany.

This company is absolutely untrustworthy

Really look this:
