correction

1 bar = 14.7psi

but i get what ur saying. thanks.

 

anyone have the spec sheet for the 06's?

i have the one for the 05's but not the 06's. i want to print it out, show them what it should be boosting and make them fix it.

 

the dealer is swearing to a stock boost of 19psi tapering to 16.

isnt the stock 9's 20-21 tapering to 17? well it really wouldnt matter because the car isnt spiking at all and not going past 1 bar.

im trying to find the evo 9 spec sheet but i cant seem to find it. i want to print it out and show them.

 

139 kPa @ 3500RPM
111 kPa @ 6500RPM

 

20 down to 16

ok thanks.

1.38 bar to 1.1

 

ok i am the kid with the evo that has the problem and thanx for all the posts.

i aint clueless and i know the dealership is bul****tin me cause i delt with problems like this before when i had a '03 eclipse. they will tell you anything to not have to work on ur car cause they wont be gettin paid from the customer cause the car is still under warranty and whatever the person told me about bar being boost to air ratio was a complete waste of breathe cause i know what bar means. i had one person tell me its 19 stock and another one agree with him and then another guy workin there had a '03 evo with mods and said that the '06 has 19psi stock.

 

There seems to be a disconnect here, unless someone can correct me...

You have a problem hitting target boost, and you are not spiking at all, only rising to 15 psi holding.

You have low(er) compression in cyl 1 & 2.

Are these problems related? To diagnose issue #1, WHY would a bone stock 9 not hit target boost pressure? It certainly isn't related to the lowish compression in #1,2, how could it be.

And what can you really expect the stealership to do/say? The compression test needs to be done again, with some oil on #1,2 pistons to watch for an improvement. In the meantime you need to keep an eye on your oil consumption.

 

I think they could be related. Too much blow-by which would cause less exhaust gases.

less exhaust gases = less boost.

 

if this is the case we would see a dramatic loss in oil correct? i dont think this is the case. i will email him right now and tell him to get his *** outside and check the oil.

 

uhm..... no. *bangs forehead* to lose exhaust gas the way you're describing would take a gaping hole in the piston - in which case it would not hold anywhere near 120psi.

 

he just checked the oil and he is still full.

i am bewildered.

ok so back to the boost leak test i did. when adding pressure to the system, u should not hear any leaks correct? i mean this sounds like a stupid question but im just making sure because i know it was leaking in the throttle body, and im assuming it was the o-rings on the shaft.

 

Have you pulled the intake off the turbo and given it a jiggle to see if it has any shaft play?

 

not yet

this weekend we will do more looking for stuff

 

the chunks of motor (be it piston, head gasket, ring...) that left the party and are causing the low compression on 1&2 went through the turbo on their way out screwing up the turbine wheel preventing full boost.

just a guess though.

 

im going to say.....

highly unlikely.
