Is your Touareg a 3 liter 6 cyl diesel? That's what I have in my 2015 Cayenne. If that's the case, with 50.000 miles maybe I ought to get rid of it before big expenses.

I read that bore scoring on water pumpers was due to warming up the engine improperly. The article said that folks started the cars and let them idle for long periods of time to warm up. This caused ...

I've done a ton of air cooled 6 cylinders but never a water pumper. Looks like a lot less parts. It should be fun.
Enjoy

Can turbo engines be run with more advance like the NAs? Vaughan and I run 41 degrees in our NA race cars. I mistakenly cut mine back to 34 degrees at my last race and acceleration was decidedly slow ...

Flat top piston...any cut out for the valves? Or does it become an interference engine? Sounds like a great way to really bump the compression ratio. Similar to putting turbo pistons in an NA engin ...

I didn't shop for stock pistons since my application was SCCA's IT-B class. We are allowed one half point increase in compression over stock. I chose to have that encompassed in the piston top rathe ...

Diamond has the specs for a turbo piston as well as the specs for an NA piston having made both types. I don't know if the turbo specs are under Dan/Ideola or Chris's (friend of Vaughan Scott) name, ...

Perhaps someone in the past had installed one of those no longer legal "Y" shoulder harness straps. They only needed one mounting point behind the passenger and driver's seats.

Sounds like your issue was the negative terminal on the battery (intermittently not connected). If your radio dropped on and off at the same time as the car running rough, they both share a need for ...

I thought about doing the same thing (cut three additional threads). But I decided to just put in a 5 mm spacer when I removed the big spacer and installed 7 inch cookie cutters on my race car. I wa ...

Mike,
I have one of those Sears advance timing lights and they are not very accurate.
I set my race car at 41 degrees at 3000 RPM and it runs great with plugs on the vacuum device. We determined tha ...

8 degrees is too much for anything. Rule of thumb is: advancing the cam moves the torque curve lower in the RPM range while retarding it moves the torque higher in the range. Usually only effective ...
