Pauter Super Pro Heads

[mikko k]

Hi everybody. First I have to apology my English, it might not be right all the time, but I hope You unterstand.

I have build a Type 4 engine for my friend. It is 2,63 liter with Pauter heads. Main use is a street drive, but sometime he plan to use it in strip, just for fun. We have some problems with valve seats, they all seem to move and unfortenately one seat came off, went in 3 peaces and cut the titanium exhaust valve. I take the rest valve seats off and I tig welded the combustion camber back to "normal". We still have to machine the heads and install new seats and so.

The reason I wrote is, have any of you, use The Pauter heads on road. I was wundering that are the cooling fins too little or not many enough for street? Or would the seats be too loose as originally? Any experiences?

To be honest the engine is a fuel injected ( programmable ), turbo charged and intercooled. With leaking valves and leaking wastegate it made at dyno only 0.6 bar boost and about 300 hp. I have allready driven it on road at 1,2 bar boost. It's still not the goal we are going to! At this moment I'm making the heads to watercooled to pass these seat problems.
