TT De-cat with afr & egt Flange pics?

As above guys anyone got any pics of the first tt de-cat with the afr & egt probes welded on?

I've ordered my de-cat from Paul Whiffin but need to get these welded on to fit new guages shortly.

Theres a 1/8 npt tap to go into the decat pipe for both guages but just need a look at what it looks like as i havent seen

it before.

Thanks in advance.

Anyone know the drill size for a 1/8 npt tap?

has your 2nd decat got a sensor on it ?

has your 2nd decat got a sensor on it ?

I'm not sure Jurgen would it be an 02 sensor if it has one? I'll need to check under tomorrow mate.

one we can drill and tap the other possible will have to have make like this lug on the pipe..

next to flange

Ah ok i see now ill check when i get in from work Jurgen and pm you. If the lug needs to be made on the pipe would you do that on the day or me prior to arrival?

JUrgen you know anybody in the uk that stocks these http://www.aemelectronics.com/no-weld-o2-sensor-mount-3-inch-1175

you can buy adpaters etc.. let me look tomorrow i will try and make it as easy as i can for you and me.

Thats quite neat!

better to have it done prior to arrival but since your 2nd decat is on maybe both on first..

Ok Jurgen thanks.

do you know anybody that sells the nut bung with threaded end to exhaust (so it can be drilled and tapped _)

nope but thats another way of doing it..

Is that this?

Is that this?

if we can find a NUT with extended thread that goes into exhaust (leaving NUT exposed) , then the AFR sensor can go into the thread in nut..

It's pointless having an EGT probe AFTER the turbo(s), it needs to be in a manifold runner or collector. I put them as near the port as possible, what you are really tying to measure is combustion temps, a probe in the cylinder is the ideal, but very costly and tricky.

11/32 inch is the recommended tapping drill size for a 1/8 NPT thread.

AFR probes are nearly always 18mm thread size, now way one will go in a 1/8 NPT hole I sell weld on adaptors and blanking bungs for AFR (O2 sensor) probes.

something like this will make my our life easier

dont worry i can nip out tomorrow and get one,.

i guess we can use the AFR on 1st decat with a bung (i will get part tomorrow) and egt we can drill and tap onto manifold runner..(if its easy enought to get too) ..

got any pics on a TT set up of were EGT probe is tapped.

I don't have any photos but I have literally put dozens of EGI probes in the number one runner right by the port on TT Supras. Just a bit of removing to get at the heat shield to either hole saw a hole in it, or use tin snips to trim the corner back. Drill and tap manifold, using grease to catch swarf, add adaptor, add probe, a few bits back on and job done. I charge £50 for doing this.
