sup guys i have a issue that i really need help with i have a 2005 evo and here it goes...i hear sort of free spinning turbo at high rpms..., liike i go and if i floor it ,after 4k rpm u can just hear the spin and the car wont respond?? any idea!

and i think its in the turbo area..?
you guys think something may got caught in there and is not letting it work properly?

 

Do a boost leak test first.

 

how can i get a boost leak test?

 

search...

 

So the car will rev but not go any faster? How old is your clutch?

 

im pretty sure its not the clutch its been chang like 500 miles ago as well as a tcase..
everything is fine if ur driving normal. but if u try to drive it hard even in 1st gear after 4k rpm u hear something just spinning and the car not going anywhere..

 

(if your rpm's shoot up when boost comes on but you go nowhere your clutch is probably slipping.) check all your intake annd intercooler connections starting at the intake manifold and work your way around. make sure they are tight. make sure the rubber couplers are pushed all of the way on the pipe.

 

i will double check! can anybody help me out on how to do a boost lleak test???
any other ideas on wat it can be??

 

Do you have a boost gauge? See if you are acheiving your set boost. or are you stock? A list of mods helps.

no i dont have a boost gauge..
but no im not stock i have a turbo back. arc box, bov
for some reason i feel its the turbo ..

 

So you have an exedy clutch and a new TC?

Who installed them?

Did you ever get all your other issues fixed, like you MAF sensor, and you upper IC When it blew off? Your HKS bov..

Has your car been tuned?

 

it was at the long beach mits. dealer..
ya everything else got fixed
no my car has not been tunned..
i will try the boost leak test for sure..

 

You should have bought a BG before the BOV and Intake.
So go buy one..

 

Fix any boost leaks before you take it to a tuner and get it tuned along with the BG/Air fuel gage installed.
