Organising an exhaust but the maker requires thread type for the pyro take off, I havent purchased the pyro yet but are the pyro threads all the same on the different brands, if not what brand would be recommended and what thread type, hoping someone here will have an easy answer...................

They're all different (VDO is 1/4BSP, Autometer is 1/8NPT).
You could just put in 1/4 and then screw in a reducing bush if necessary (that's what I did).

Get one of these pyro, can put a warning buzzer on them , high& low temp.,for a couple of $. I think the thread is also stated, Auto gauges, EGT Boost : auberins.com, Temperature control solutions for home and industry

I had the same dilema when i bought my Scotts Exhaust. His solution was to weld a 20mm steel adapter into the dump and to drill and tap the 20 mm plug for your size pyro when you get it.(its big enough for all pyros) It worked a treat. doesnt look too untidy either as its covered by the heat shield.

I got an auberins, it came with a 1/8 NPT thread on the probe dooflicky, which, as it turns out, is a pain in the butt kind of thread to find (you wont find one at bunnings). I got one from pirtek at great expense to the management, and cut it in half; welded to the dump pipe.

I kept the dump pipe / cat assembly when i got my 2 3/4" exhaust fitted, will put it in classifieds in case someone doesnt have welding skills to modify it them self..

NPT will screw into BSP, it's only the thread angle that's different.

I reakon it all fits eventually, just have to use a bigger adjustable spanner until it does

Mine wouldn't. I originally got a 1/4 to 1/8 (both NPT) reducing bush to try and force into the 1/4BSP thread. The thread binds after two turns and won't budge. You can get NPT to BSP adapters (which is what I did).

Wrong, thread angle and also thread count (threads per inch).

1/4"BSP is 28tpi and 1/4"NPT is 27tpi from memory.

Actually the VDO standard is 1/4"NPT. But they come in almost any size you want them.

Personally Id put a 1/4"NPT and then you can always adapt anything to it.

Im installing my gauges this weekend. Rather than starting a new thread, is there a step by step on how to install the boost gauge on this forum?

Sorry for the slight hijack

Yeah there is tonka, search for it. If you can't find it let me know I'll take some picks and email it to you.
Cheers

meh im searching... cant find any threads with lots of pics on how to.

Fair enough. That's one more thing that Denco got wrong then...

Looks good and a fair bit cheaper than an autometer, where would a good place to install one be?

1/4"BSP is 28tpi and 1/4"NPT is 27tpi from memory.

As the thread is usually only 20mm long, and the crap standards of fittings they tend to screw in OK, the other poster must have being unlucky to get some higher tolerance fittings. I'm always screwing NPT into BSW, as it too difficult to keep a stock of both sizes in every type of fitting.

Mine is below my sub tank switch

cheers mate, ill most likely do the same + hoping I can get a boost gauge in there too?
