If I said I am running 7psi I made a mistake its only 6psi.
The last two days with the weather here so cold (its around 30!!) I have seen and felt 6.5psi. and 7 once or twice.


I think there is a rule of thumb for the whp to crank conversion. I think its 1.14 times the dyno number but I am not sure at all.

Here is how I did it:
Porsche claims 201 at the crank my base line dyno showed 164

164 times 1.22 is about 201.

226 times 1.22 is 275 crank.

I will assume right off the bat someone has a better way of finding these numbers but this is the "logical" way to me.

Growing up the car magazines said how amazing Porsches are. Was I brainwashed? Somehow...I doubt it.
