Turbo Questions

Question for our install this morning... the manufacturers of the kit I bought tapped the block for the oil feed. We want to skip all that work and tap the pan. Any reason why that would be a bad thing?

Hi ChinoCharles,

Are you planning to tap the oil pan for both the feed/return of the oil for your turbo?

I would recommend you to tap the feed from your oil pressure sender and tap the pan for your return. You want to do that to ensure your turbo gets the oil feed via a constant pressure.

I too asked my tuner to skip all the work and tap everything right off the pan, his justification is that if we're driving the car in extreme conditions such as taking a hard corner fast, the oil inside the pan could be "pushed" against the side wall of the pan, and there is a chance of a vacuum being created resulting a situation whereby there will be a temporary cut of supply of the oil to the turbo. Not sure whether it makes any sense to you.

Also, if we're tapping the feed off the pan we need to calculate the correct height. Too high we might not be able to guarantee a steady supply, too low we risk sucking up all the particles at the bottom of the pan, although you could minimize the risk by using a magnetic bolt nut or use a magnetic oil filter such as one from Power Enterprise.

Alternatively, you can just use an oil sandwich adapter and add a pressure and temperature sensor for monitoring purposes as well.

But I would recommend you to use the oil sandwich adapter for an engine oil cooler, as the oil will be warmer since it is shared by the turbo as well. It is really a good investment even you're not planning to take car to a track or down the drag strip.

Just my 2 cents!
