Question regarding TIT

[gsxrpilot]

Does this formula work with my MB engine? And can you break down the formula for me? 

(9 X 13.7 / 210)

9 - gph

13.7 - ?

210 - ?

Thanks.

Yes,
13.7 is the multiplier for 7.5:1 pistons, and 210 HP. Good for all K’s except the 220 HP Encore.

Perfect, thanks!

The %hp calculation is highly dependent on the compression ratio of the pistons/cylinder combination...

Fortunately the CR for our planes is easy to look up in our engine specs...

Nothing better than having Mr. Kortopates deliver that message for an M20K.

Just throwing my hat int he ring here.

io-360-lb, intercooler, gami's, tempest fine wire plugs, jpi 830.

What i've found best on my engine is to do the big pull and keep my TIT under 1600, generally around 1590.

engine temps are fantastic, runs smoother, and last flight was true at around 155 on the aspen and 9.9gph.

Can't complain around that!

+1 for the "Big Pull"

My process is not to actually "pull" my mixture, but I turn it back REALLY fast unti my TIT peaks and comes back down, then I adjust to get my tit around 1590. Purrs like a kitten.
