I was wondering if I should install the heater transducer and the pressure sender for my electric bottle pressure gauge before the N2O filter. I have a fitting that has 2 1/8" NPTs for the transducer and the sender, but should I mount it directly on the bottle or mount my 6" line, then the filter, then the fitting for all the electronics? Just looking for recommendations.

Thanks,

Matt M.

 

IMHO the heater pressure switch has priority on being on the bottle, so that it will correctly function with the bottle open or closed. If the heater pressure switch is anywhere on the mainline it will only work with the bottle open. The last thing you need is to be heating the bottle and forget the heater is on with it closed, and heating to the point you blow the rupture disc and waste the precious juice into your trunk or out your blowdown tube...

Here are a couple pics (ones a dynotune bottle the other an NX bottle).

 

Yes transducer at the bottle before the valve, however even this location on some bottles the bottle needs to be open. On the gauge transducer, i like to mount it in the engine bay to clean up the look of the bottle, and easy to hide. Pics in my web.

I have a total of 4 ports on my bottle: blowdown tube, main line, and then 2 1/8 NPT ports. I guess I can just put the transducer in one and the pressure sender in the other. thanks a ton!
