compression results
well I just did the compression test on my car
on the rear rotor I was pulling 95-105 psi on all 3 (couldn't tell for sure the exact number) think it was more around 100 though
and on the front rotor I was pulling around 105-115 (again couldn't tell for sure but I think it was around 105
what is the stock compression arting on the s4 N/A?

think I have a chance of hitting 250k?
why is it also that the rear rotor always seems to be lower then the front?
oh the test was done with both leading plugs out and the car at WOT
that is the right way to test it correct?

Yeah man, seems like you are doing a great job of maintence on the car. IM sure you can probably reach 250K if you continue with whatever you're doing. IM not sure about the rear one being lower than the back, but my theory is, which might be wrong, is that the pressure comeing from the OMP is greater in the front bc it has less distance to travel than in the rear and it gets more lubrication. Again, this is just a theory i pulled out my ***, no accual evidence to back it up. Other than that, i have no clue. Anyone?

The 13B in my GSL-SE has 180K miles and has identical compression numbers as yours. Still pulls great but I am starting to get a little too much fuel dilution in the oil. Be weary of that, if it stays around the full mark all the time, you will need to replace the oil monthly. Oh and using a little premix won't hurt either. I use 1/2 oz/gallon.
The rear rotor goes out first cause the rear part of the eshaft sees the most amount of flex.
