Using an AF ratio meter on our Porsches

[ttAmRoadsterAWD]

Oh, and one more thing....to keep close tabs on the head temps, from what I understand, I need to get a gauge that gets info from a washer-like sensor on the center spark plug.....guess I'll need one for each side?? Or are there better ways to do this??

what's the "preferred" way? Who makes a good kit?

They are for turbo hence the boost. I would think the break between mid and high boost would be about 0.8 bar.

Does anyone know if the twin turbos already have temp sensors?

Not that I know of that is actually capable of being monitored on the dash- correct me if i'm wrong. Westach makes a quad cht gauge (or other configurations 2 egt 2 cht) that fits in the place of the clock :-)

The number you want to stay under is 400F sustained. The cooler, the better. Our four cylinders running Nickies making 50+ hp per cylinder run typically 265-295F under a full load for comparison.
