I'm going to do a test and i need to know what the compression should be or where it should be around.... Please answer this and dont be a smart *** please!!!

 

brand new condition is 205 on each cylinder. your compression is going to vary between each clyinder. your maximum minus your minimum should not be more than a 20psi diff. your minimum compression on anyone one cylinder should be 165 (i think). I'm not too certain on the last figure. IE mine was 190,190,190,185. it's normal for one clyinder to be stronger or weaker than the rest.

 

is it 205 for 1st and 2nd gen?

 

yup.

 

I'll check mine today and post what they were tomorrow.......

 

my 1st gen has 235/240 across the board.

 

compression numbers depend on a lot of variables....general rule of thumb is 180 psi is "a healthy motor" anything above can be considered normal as long as cylender variation is no more then +/- 10Psi

 

i just did mine last night...


205-205-205-200

Also make sure your battery is fully charged... and you throttle is wide open!!!

4 to 6 cranks will be good..

 

Why does your throttle need to be fuly opened? Does it affect the numbers? I tested at 192.182.182.182.

The throttle must be fully open because w/the motor only turning at cranking speed the motor doesn't have the ability to take in air as easily.

 

So this will effect my compression numbers. Also I saw your signature ... email me on a price for a b16 port and polish job and where you are located. I am building up a head right now

 

Yes if the trottle bades aren't fully open you willusually see lower #'s.For a fully ported B16 $850,I'm located 10 mins south of Philadelphia Pa

 

I still havent checked mine......but today for sure....if i dont forget!!!!!
