250HP out of a VW engine isn't going to last long, I don't care what any "expert" says. VW's have oil-cooling issues even at 100HP. A VW pumping out 250 is going to chew itself to pieces in no time at all. I've seen some VW-based club dragsters like PT is talking about, putting out that kind of power from a bored-out Type 4 engine with the euro pistons, but that literally was only for a few seconds at high RPM, and they practically had to rebuild the engine after every event.

Putting out 250 for hours on end is a totally different animal.

your almost better off with a Marine Engine then an auto conversion, IMO. Marine engines run 75% full throttle for hours on end in boats, i don't see why one can't do the same in an aircraft application.

Well, it's interesting, but it is not a VW. Does it even share one component with an original VW? Looks like an entirely new creation and not in any way comparable to what can be done with the VW types we usually see in airplanes.

Blaine,

I'm a new poster to this blog. Very interested in an update on progress you have made and additional info on the marine ECU to eliminate all of the auto sensor constraints. Can you elaborate please?

I have an RV6A under construction and might yet consider diverging from a conventional O320 Lycoming.

Thanks!

The MEFI 5a ECM from the GM Parts Direct, P/N 12607802, is a marine application with none of the auto related parts but all of the good engine reporting data.

it is hard to say what the boost level of the engine is, according to the calculations i did the engine needs to run 15-20lbs of boost to get 205HP, but once again that can't be accurate, there are way to many things that can be done to get that HP out of the engine, If you run bigger injectors with higher pressure lines that will increase your base HP over that of the block HP. if such is the case it can change the whole VE of the engine and thus the HP and boost.

You need to find the boost and the BSFC first before you can say that the engine runs x amount of boost for example.

1,400HP i casn't believe, that is over a 200% increase, especially for the displacement of the engine, now 400HP is the most i could see that engine putting out, and even then ITS NOT A RELIABLE 400 HP. just remember that.
That engine can produce 200+ HP with 8 psi boost..reliably..

I'm curious as to whether anyone's gotten further with these things. I'm driving an '06 HHR with the 2.4, and am very happy with it as a car engine, and have wondered how it'd be in front of a CH801.
Maybe even a 750, slightly derated.
