Yes they work,some better than others. They will keep the oil cloud down and keep more oil in the crank. My 944 has a good stock system in the pan and Jon Milledge says they only help my car very little. Dont know about yours. If you are losing any oil pressure in corners I would consider it. Some cars get 5 HP from one,or so I am told. Is its legal in IT.

5+ hp at the top end (7200 RPM ) on my 1.6 VW Scirocco engine in GProd. I use it in addition to the Techtonics style windage tray.

It's free horsepower and if I had an IT VW I'd definitely have one.

Hey Mark, are those an off-the-shelf item for a 1.6?

No, I make a template for each crank/rod combination I use to get it as close to the crank as a I can . Typically I allow .030" of clearance to the scraper. Then I send it to Kevin at crank-scrapers.com and he makes the scraper to my template.

The off the shelf ones have more clearance and will help some, but the custom made ones are even better.

Yeah - not so easy with the 1.5. The dang crank never clears the bottom of the block. We need to make an angled one for Mathis' motor.

Quick question. Do you use an extra oil pan gasket with those? Right now we use a ABA windage tray in our 2.0 ABA. A scraper would go on top of that, but then I suspect one needs another gasket to keep all the oil in?

Oh yeah? I tried to GIVE Chuck a polished 1.5 crank with matching scraper...he wasn't interested. :P

Yep, I use three pan gaskets on my setup. Just need extra long pan bolts, easily obtained at various suppliers.

He probably thought it was too heavy :119:

Every time I work on that car I think about how cool it would be to work in a machine shop....
