02 sensor placement on single turbo v8

[66larkgs]

should i put the o2 sensor in the crossover pipe, before the turbo on bank 1 and the turbo is on bank2. should i put on in the exhaust after the turbo. i have a F.A.S.T a/f dual o2 sensor setup and would like to moniter both cylinder banks



thier is a picture of my engine on my build thread. i will post one on this thread tonight.

Thanks Paul

I was wondering the same thing since I'm wantin to run a single as well. Mine would be header/crossover/log manifold. I don't see the log side reading correctly at all.

I didn't see where the crossover meets the passenger header on yours, maybe put an 02 in each collector??

I doubt I'm any help here but its worth a free bump anyway....

Turbo cars need to be after the turbo. Unless you've got 3 sensors 2 in the banks and one after the turbo.
