Searching for alternative to stock 3.2 CHT sensor

[jons911]

I've been using the stock 3.2 CHT for my turbo conversion, but I would like to move to something that shows me the full operating range. Unfortunately, I'm not at a point to wire in something else, so I'm stuck with the basic two wire temp senders. I've found the temp senders at Westach have a chart that includes 300 F and 400 F at the top of it's range, but it's not available in the M10x1.0. He was pretty helpful last time I called, but I wanted to see if anyone has a drop in replacement they're using before I see about a custom sized version.

In short, does anyone know of a temp sender that goes to ~350-400 F? Or know the resistances beyond the oem table for the stock sensor?

Thanks
