[manny 2004 banshee]

my compression was at 105 psi. Somebody said that i would need a new top end soon. Does anybody know at what psi i would need a new top end?

that may be. ideally, you want 120-130 at sea level, but the readings can be off due to elevation, method, and the tester that you're using. 5 psi or more difference, on the other hand; it's time for some work

umm your good id rebuild at 90 or like a 7psi or so diffrence

 

 

but ak is right it depends on how you did the test and with what tester

just curious are you holding the throtle wide open while you are kicking it over??

no i start off with no gas, then if it doesn't turn on i open it some, then i give it all if it doesn't turn on

when you are doing a compression test you are suppose to hold the throtle wide open while you are kicking it over till the needle stops moving..thats what i was asking..just curious

[swrbansheeboy]

yes, when doing a compression check you need to hold the throttle wide open.

 

also, what type of set up are you running?

 

if you have a stone stock engine then 105 isn't too bad, if your running a cool head with 17cc domes then 105 sucks and it's time for a rebuild.....

mods dont matter. hold it WOT and kicked the hell out of it till it dont go no more. Unscrew it and do it again to insure it had a good seal.
