Pressure transducer location Q
 

For those of you (if any?) who have used pressure transducers in rotor housings, where did you install them?

Im currently planning on installing them below the leading spark plug between the two tension bolt bores parallel to the plugs them self


There seems to be no information on this anywhere i look, so any help would be appreciated.

Which transducer are you using?

I have tried Optrand 0-3000psi sensors in the spark plugs.

I haven't decided on the brand, waiting for a distributor to drop a little more literature at work.

The spark plug idea sounds nice, and that would save me modifying the rotor housings to accept any sensor.


Did you piece your setup together yourself or go with a ready to go system.

I was hoping to build something to capture pressures on a per degree accuracy and export peak pressures into the innovate motor sports data logging suit however something like TFX's units look rather attractive

But if you install it in the trailing plug location (which I imagine you did Barry?) you would miss out on the effects of the trailing spark and split on combustion pressure. Seems like it would be a lot easier though!

I am using TFX but I don't have much to tell. I hurt my two non-TFX related sensors .

I am waiting for a new sensor now.

My thought is that if we use it in the leading it will sense the exhaust port opening and if used it in the trailing it will show the intake closing.

Are you able to modify the plugs to accept the sensor yourself? Or is this something they have to do.

Hurt non-txf sensors how? is the 3000psi sensor not enough of a range?

Thanks

I modified a 5/8" plug but it overheated.

Would you recommend the water cooled sensor then?

No experience with water cooled. Might work.

Hopefully more testing soon.
