Blowthrough AFR's

[70wayfarer]

what should the afr's on a turbo blowthrough application be at idle, cruise and WOT.
I have got 11.7 at idle, which is way out.
cheers

From what i hear, idle doesn't matter, you just need to find the best vacuum.
At cruise 13
On boost or WOT 11

That's the basic numbers from every turbo forum I've ever seen and that's on any motor.

pretty much what he said. can go a little leaner on the cruise. i shoot for 11.5 on boost.

I idle at 14.3 +- Cruise at 12.5-13 WOT at 11.2 +-
