I plan on buying a DC manifold and tapping it for an EGT sensor on the runner #2 (2nd from the passenger side, correct?) about 2 to 3 inches away from the head.

All my searches say this is the best location! Is this correct?

My other question is: Is this a good manifold?

Seems better than stock from the dyno graphs and I don't plan on upgrading turbos at all. Searches don't bring up any bad comments about it. I would like to see a comparo between ported manifold and it, but have not - thus far.

The DC manifold makes sense based on my goals with the car: I plan on basic bolt-ons and upped boost with EBC and flash and calling it a day. I don't want to overdo things with this car. Just make it look decent, drive decent and easy to maintain. I don't want a tuning headache, I have no time for that. Everyone has different goals and I respect yours, so please do the same for me!

So, if this a bad choice, then I will lay off it, but any sound advice is greatly appreciated!

Thanks!

 

I like the way the dc sports header looks in the collector!

what dyno graphs are you refering too?

 

look at last post here:

The gains look impressive down low.

As to where to put the egt sensor, my advice is to have it installed where the weld will be good & the replacement of the sensor is easily accesible.

IMO where the egt probe isnt to important on such a short run of a primary pipe.

In my experience of high revving n/a & turbo engines, the closer you place the egt probe to the cylinder head, the sooner the probe & or the welding of the bung to the pipe will fail due to vibrations.

Good luck

 

The bung wont be welded on. The manifold will be tapped and the probe bolted on. Thats how I have done it in past DSM's...

 

I would suggest trying to put the sensor to the collector instead of the number 2 runner

 

Essentially you want to put the sensor on the hottest cylinder/runner, an overall temp reading is nice, but there is a loss in heat from the begining of the runner to the end of the collector. Find the hottest cylinder/runner (search) and place it 2-3" away from the flange.

 

tvieira24 -If you read my first post, I said the same thing as you! I will ask the experts who I am buying the zietronix from as well and see what they say! Thanks

 

Tap a tubular manifold? I am not sure if this is a good idea. I have never tried it beacuse I just weld them on.

What is the manifold 16 gauge? doesn't seem thick enough for a tap to me.

I can't comment on that, I've always tapped cast iron manifolds with a pretty thick sidewall. 16 gauge is about 1.25 mm thick and seeing how 90% of tubular manifolds on the market use 16 gauge, it'd probably be a good idea to weld a bung (to be safe). It'd prevent cracking around the actual tapped hole and would also give the egt sensor more to "bite" into.

 

good point,guys. I guess I don't know enough about tap vs weld. I have only tapped DSM cast manifolds as well. Time to research...

Thanks for the link. I don't like the hose clamp style. I did see they had some weld-on bungs, though!

 

Talked to DC Sports. The runner wall thickness is 0.065 inches = 1.651 mm. Zietronix needs at least 3mm to thread on. So, welding is the only solution.
