Hems,
David is right....Ian is very easy to deal with. Fitting is very easy, especially if you already have the tapped hole in the dump pipe. When I first fitted
mine I didn't have the new Denco upgraded turbo/dump pipe, so I had nowhere to fit the thermocouple. On Ian's advice,I got a hole drilled and tapped into the manifold, just before it joins the turbo. This gives a more "accurate" reading of what gas temps are hitting the turbo, which is, after all, what you need to know. The temp readings in the dump pipe can be up to 140oC lower than the manifold. It was a real eye opener to me.......I'd always thought a turbo 'created' heat; whereas it actually absorbs/dissipates heat from the exhaust.
I quoted some figures above, for temps that I work off before switching the motor off. Please bear in mind that these temps are what I'm reading in the manifold, not what you'd be expecting in the dump pipe. If using this set-up with only the dump-pipe thermo-couple, I'd be suggesting a shut-down temp of around 180oC or thereabouts......but Ian will know more about that.
Just while on the subject of monitoring your motor, David has been very professional by not mentioning his own product in this response......... I have no interest in his company/firm, but I am a satisfied customer and I drive with a renewed sense of comfort/confidence now that I have one of his Low-Water Alarms fitted to my top radiator hose too. Thsi is another easily fitted component that I can thoroughly recommend.
Cheers
Roachie
