hey guys im all new to this turbo thing i recently bought a 03 evo 8 and put a hks ssqv blow off valve! My car seems to lose all its power around 5000 rpm and my turbo only boosts up to .5 on my stock boost gauge the dealer told me it supposed to boost up to 1.0 anyone have this problem or any suggestions what i shoud do????

 

ya get rid of the ssqv it sucks *** had the same prob doesnt work with the mass air senser buy a different bov

 

its that crapy ssqv, i run a greddy type rs recirculation, its still loud but it helps with performance as well not like crazy but just helps in general

 

Yeah, vent to atmosphere BOV valves will do that.

Recommend you run the Evo 9 metal RS valve. This is a cheaper solution and will work fine unless you're running a bad-*** turbo.

 

get a forge rs bov, i had a ssq -- big mistake

 

i have a FP bov forged performance not *forced performance* forged lol but it allows you to control the serge

 

Full boost on your car should be a little higher than 1 bar. 1 bar=14.7 psi, stock boost is 19, just so you know when you're hitting full boost.

 

Do not get another bov the stock one is fine until you really start increasing in boost. The aftermarket bov doesn't work well with the mass air sensor unless they recirculate anyway. The only advantage you get from aftermarket at the lower mods is a louder blow off and thats stepping into ricer world. Do the typical newbies mods that well proven intake filter kit, exhaust upgrade, ecu tuning, cams, intercooler and pipes and work your way up.

 

aps bov ftw

 

 

i got a stock 8 valve if you need 1

 

was it boosting low when you got it, or after you put the bov on?

 

what about tial bov? I'm planning to run tial bov with maf sensor.
I heard with good tune it works fine.

 

19 psi = 1.31 bar. You can type this into Google search and it will do simple conversions for you.

Revert the car to stock and check for boost leaks. Make sure your boost gauge is tapped into the right line. Search the how-tos on this site for the correct location.

 

def. the bov. is your problem
