P/C Mahle 3.4 7:5:1
 
general condition is good

2 piston rings and 1 oil scraper ring were broken, it was not easy to get new one`s.
there are 2 different versions of the 3.4 liter set.
only RUF in Germany had new one.

I modified the cylinder (old school know how)

Please tell why you made the cut-outs in the cylinders.

I know why we did it on two-stroke engines, but gather this is not the same.

proffighter 07-22-2014 03:44 AM

That's a classic tuning procedure (boattailing) to relieve gas exchange or breathing between the cylinders and the crankcase (volume below the piston). According Bruce Anderson 10 more hp for a 2 liter engine. This needs also machining the crankcase like this which correspond (red) to the slots in the cylinders:

I do not have seen any dyno to proof, but because I don't see any downside except the work it's worth a try

Thank you Roland for the illustration!

I have picture from the Bruce Anderson Book (German Version from Roland)
This modification was made at all the factory 2 liter racing engines.
