Has anyone ever fitted an extra knock sensor on the exhaust side of the block?

There are some good block spots (m8 tapped boss) that I can easily get to on the exhaust side between oil and water outlets to Turbo.

Trying to fit an extra one on the inlet side is a headache (engine in) and I cannot see any reason why not on exhaust side.

This is for an aftermarket monitor, the OEM sensors are used by my G4+plugin

Appreciate peoples thoughts!

What engine? They have different amount of bosses on the block.

Rb26 single, was thinking of using the bosses that the old twin turbo supports bolted to.

Not about the bosses just about using knock sensors on the exhaust side.

I suspect that there is no mechanical reason to mount them one side or the other. I would however suggest that anything on the block on the exhaust side would need to be made out of asbestos plated titanium NASA oblative shield heat resistant Shuttle reentry tiles to have a significant life. It's not really the ideal location for wiring and piezoelectric microphones. Consider heat shielding of some sort to be compulsory.

Yeah planned on that, have a full race ts manifold which is a million miles away from the sensor.

      Need AC Compressor for R32

      R12 has not been not available for....decades now. Propane is not a great replacement. (I mean, it's a great replacement, but it is a bit too flammable). R134a being the only way to go forward with an R12 system. The design pressures etc, are close enough to R12's to work. The ability to move heat around is close enough to R12's to work.

      Out of curiosity, what's the reason for converting? I think @R3N3 might have the Frenchy's kit in the R33? I somehow think of you as the ambassador for realistic and clean street-driven setups nowadays

      careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?

      OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.
