would anyone happen to know the max value of the compression psi for the d15b7? the chilton manual doesnt seem to have it, only the ratio (9.2:1) so any help would be greatly appreciated. i want to see how good she is yet after 161,000

 

no one knows? please

 

it depends if you test it cold or warm. As long as the cylinders aren't more than +- 10 psi of the median, I wouldn't worry at all!

Edit- like if it's 190-195-190-160...then you know you have a problem

What do you mean max. pressure in PSI?

Do you mean the maximum compression ratio, which has nothing to do with PSI?

Do you mean the maximum amount of boost in PSI that the stock engine can handle?

 

he's talking about how much psi should read on the compression gauge

 

i did it the other day and i think they were 200, 200, 190, 187. that sounds bout right anyone?

 

thats ok !!.. not anything 2 worry about !

 

I'd keep watching that 187 and make sure it's not dropping anymore, but nothing to worry about right now!

 

thanks guys. now that i think about it, i think the third one was 194. just a side note!
