cali pyro sensor in test pipe
cali pyro sensor in test pipe
english red rat rod 1977 240D, OM617.952 burning B99.9, iron 4-speed & 2.88 diff, 195/60/R14 on alloys, 5mph bumpers, battery in the trunk, 25mm swaybar, 4x ECE H4 lamps, double brake lamps, deleted sunroof, export zoll & california blue plates
i can see why exhaust manifold is the single best place for the sensor, but in the test pipe would work pretty well too, right? i ask because it's a chunk simpler to drop. thanks.

Not really, a lot of heat is used when the exhaust expands in the turbine of the turbo. If its a no turbo car then probably the down pipe would be OKish..

Exactly. That is the whole principal here. Recouping the energy lost as heat into a useful kinetic energy of forcing induction. Directly in the exhaust has got to be the place to measure, not somewhere else down the line.
Nice body, tons of ridiculous mechanical issues - 300d turbo 82' /motor 85'

I think you're good putting it there, I doubt the EGTs would drop what 50°F in the test pipe?

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

08-15-2013, 03:22 PM #4I think you're misinterpreting-he's talking about putting the pyrometer pre-turbo, but in the california emissions cat-delete pipe instead of the cast manifold.

PS anyone know what that little bracket on the front of the test pipe is for? it made me remove an oil cooler line i would have otherwise left in place.

exactly S=B. thanks all.

There is a brace that goes from that bracket to the motor mount. That brace is important for supporting the turbo.

I would think you want it in or nearest the turbine inlet do to the pressure being the greatest at the inlet, that would most likely give you the most accurate reading.
