Static voltage.

Car reads 160 across with throttle closed dry/cold/hot
180 across closed throttle and wet.

Cold open throttle car is showing 175-180 gauge is hard to read very accurately plus i was getting tired.. None the less they are close.

Every cyl cold showed a 20psi increase at WOT by adding 1tspn of 10w. Each was very close to 200 if not right at it.. This motor is over 60k old and was built in 06.

Are these cold/dry/wet increases typical? 20psi on a 180psi motor? I'll do a WOT hot dry/wet test tomorrow and get numbers

Also lastly whats started me with this is my #3 plug has been turning a darker color than 1,2,4. Which isn't the normal, i'm leaning tward maybe a injector seal causing a rich situation in just that cylinder. If it helps i'm on e85

 

so at a cold compression test you were reading 160?

 

175-180 cold/dry 195-200 cold/wet

 

I'm at 160psi warm/dry... I think... I don't remember

 

he's at 10:1 according to his sig

 

i'm more or less wondering what is acceptable or "common" for dry/wet differences..

if your 160 dry what wet?
