Tail Pipe Sniffer

SLC Free 2

I have an Sunbeam Tiger (331 V8 with a race Carb), basically a race car now. I forgot to weld in the bungs for the O2 sensors at the collectors so my option being lazy was to purchase a couple of Innovate tail pipe clamp on for the sensor. It I have short turn downs right after the straight though mufflers with 3 inch pipe in and out.

I have heard from others that at the end of the exhaust the readings will be a bit on the leaner side. Any one use this type of set up? Using to set up idle and for static testing until I get the bungs welded in.

Thanks

As long as there is no catalytic converter then it should be fine. During light load the lambda/afr might show leaner than reality as outside air maybe pulled into the clamp.

Thanks for the info!

I have no cats on the car. Not sure how well the Innovate clamp will work, it’s pretty short, odd design, but no idea how well it will work but will keep an eye out ones I get it all going
