i would just take the head off, prolly the easiest way, i would have expect the valves to of been bent

 

I doubt they would have been bent, if the car has been running for this long. Im no stranger to internals, but a bent valve would have been pretty noticeablem if not catastrophic for the rest of the head.

 

trust me... we all were....

If that was the issue... I would of yanked the head a while ago, fixed the issue, and continued back to a kick ass 2.7 tune w/ meth.

 

i cant think wat would cause pressure on ur cyl.

 

Dont feel bad, none of us do.

 

nor can anyone else...

as shaun said before... this issue has been sort of brushed off, and the same ole answer of "it's fine" is used.

 

maybe pistons, spark plugs, crankshaft, or cams?
im googling this **** like crazy i wanna know wat would cause this

 

....

car problems suck...

 

did you buy the car new? maybe a previous owner has higher compression pistons installed?

Maybe port the head?

 

bought it bran spankin new on may 6th of 2007

 

hm...hey can I get my car tested as well cuz I think i might be in his same boat...

 

how much are you boosting on that 2.8?

I boosted 17.1 psi w/ the 2.8 and full 3" catless exhaust. difference between you n I is that have the noodle header, which I believe restricts airflow some.

 

****** 13-14 psi and then it varies sometimes...at night i saw 16 one time but I have been tuned differently now...so yea idk man something is up...

 

Yeah i took my car to the dragstrip for the first time last friday
1/4 mile=14.7 @ 101.61mph
not what i was expeting at all...i did have a shitty launch too

 

you went with all those mods in your sig? or was this be4 those...

 

Your exactly where you need to be dude lol. Back when my car ran properly, on a 2.7 and just a custom 2.5 catback w/ a ported blower, I saw 15-16 PSI.

Best way to check to see how much you truly boosting is whether or not you have PSI or KPA set up in your config file while you log in HPT.

Do a pull in 3rd until 7k.

if its KPA...

use the conversion tool located under tools. subtract the converted number by 14.7 and thats your PSI at that RPM.

if its psi... well there ya go...

what was your 60' a.k.a launch?

cause local LNF guy I know ran a 14.2 @ 101.6 w/ a 2.3 60'

 

oh ok...well i thought it was supposed to be more but yea i will check in hpt again and see thx..
