installed a greddy type s bov the other day. i done the spring mod. i'm having two problems.

1. having a hard time getting boost not to spike. spikes if i try to run more than 19 psi

2. My car feels slower than before. even my girlfriend said something about it being slower!! it is not the fastest evo but i have ran a 8.3 1/8 mile so its not slow!!!

please help, i like the sound of the greddy but i'm to the point where i want my stock bov back!!!

umm... weird. Mine actually seems like the car is smoother and pulls harder. Did you have the adjustment screw set correctly? Or is the bov installed correctly?

 

need some info... what mods are you running and have u checked all vacume lines and hoses?

check to make sure its not in backwars and all lines are hook up corectly

 

i have tried changing it several times nothing works.

 

checked all lines and made sure it was in correctly.

 

get rid of it and get the MR bov

 

i thought about that but i like the BOV sound to be loud. do you know if it is louder then the stock evo bov.

 

no same sound as stock. Take the bov back off take it back apart and check the spring the seat and reinstall. Also do you have the line from the intake manifold going to the top nipple or bottom and do you have either one plugged?

 

Sounds the same as stock. I had the type s and loved the sound, but had problems with it on my car and only mine Do you have an intake pipe? If not get one and you will notice the bov more.

 

read thru this i have the same bov no issues... http://www.evomoto.com/tech_info.php?tPath=1&tech_id=7

maby you could be leaking a bit did you put the plumbers tape or teflon tape on the set screw and the nipple screw threads?

 

i have taking it apart several times to make sure it is seated. i have the hose on the top port and the bottom port is not capped off

 

thats the correct way hmm i dont know bro.

 

Only way to find out if it is slower......

Run it at the tracks.. Butt dyno is always deceiving.
