Hi guys, I was wondering if anyone had any experience with this product(s) from CB Performance:

Will this setup yeild accurate numbers?

Thanks,
Andy

Accurate enough for most people. However, accuracy is always improved when a temperature sensor is placed with the sensor tip in a path of flowing oil. With nowhere for the oil within the CB adapter to go, you are in fact measuring the temperature of engine case in and around the area of the stock sensor location. Any temperature spikes will be smoothed out and response will be suggish.

Thats what I figured, just wanted to double check. I heard that the type3 blockoff would be good. I currently have my berg shorty there. Its tapped for 1/8" NPT if I recall correctly. Would this work there:

I guess the better question is, "Is that sender smaller than 1/8" NPT"...otherwise I can always tap it larger.

Wait a minute, I don't think oil passes by that blockoff, so maybe that wouldn't yield good results. I've got all of the galleys drilled and tapped, except the big one towards the bottom right of the case. Any other good spots?

Thanks,
Andy

The sensor in the line is far larger than 1/8" NPT (it looks more like the one designed to replace either oil pressure control/relief valve screw plug on the underside of the engine, or maybe the drain plug). Any location within the sump is better than at the stock sensor location because you will at least have fresh oil sloshing against it.

Right, but I also have an add-on sump too. Any problems with there in theory?

Thanks,

Or maybe I could put it in one of the galley fittings where its tapped. That would definetely be oil moving over it. I was hoping to leave the Berg shorty in there too. It'd be nice to have the gauge to see relative increases and the Berg shorty to give the gauge's reading some credibility.
Or I could tap the Type3 blockoff plate for the gauge sender beside the berg shorty. But I was still wondering which place would be best for the gauge?

Thanks,
Andy

The gauge? How about in one of the panels beside the speedometer? Many aftermarket panels are available with holes already cut.

Haha, max I was talking about the sender when I said "gauge sender"...if thats where the confusion was.

Basically I just need to know if the typeIII block-off will give me accurate oil temp results if I put the temp sender there. And keep in mind that I have an add on sump(if that matters).
Otherwise, I could use a tapped oil galley...any good ones to use?

Thanks,
Andy

Well, there is a large plug in the pump intake galley. It's just to the right of the pump cover. I have heard of people tapping that to accept the temp sender instead of just a plug.

Haha, ironically I think thats the one I didn't have tapped. Can't remember my reason at this point. It looks really close to the type3 blockoff plate. Would there be a significant difference?

Thanks,
Andy

A difference between the two locations? Sure.

That plug opens into the galley formed by the oil pickup tube (you'll be looking right into the end of that tube) and a short diagonal leading into the pump itself. Oil at that point is moving rather quickly into the pump. Changes in temp should be picked up very quickly.

The type-3 dipstick location just opens into the sump.

I've read about two schools of thought via this forum.

1. Get the temp. reading where oil is moving(like a galley).
2. Get the temp. reading in the sump.

Apparently the galley idea is better. But I don't see any other options for me at this point, so I'll have to use the type3 blockoff.

Thanks,
Andy

Andy,

There are senders for use where the rear relief plug would go, you can get one of those and just screw it in, in place of the threaded plug. Then you have no tapping to do, and it's an ok place to sense the oil temp, since oil is constantly running close to it.
