cuz de car where it iz doh hav a bov and wel it duz sound like if it ha one buh de ting bout it wen i did now geh de car an mash down u used tuh like sink into de seat buh now wel it still reachin full speed buh u eh gettin dah feelin again so it need tuning??? or de turbo goin??
May need tuning.. check and see if you have any boost leaks... that might be causing your issue... It would be a good to invest in a Recirculating Blow off valve
As you are you may very well be getting surge especially if you're running high boost. And it can damage your turbine blades... or even crack the housing and loose boost among other things... Is the turbo leaking etc ?
check with W2J on the forum... he sells these as well as other well established parts
You need to check the car for boost leaks.. it's possible you have leaks somewhere and the loss may be causing the car not to feel as responsive as it did before.
Pm a couple other evo owners and hear what they have to say...
Pornstar, No CT9A, Freak etc... and again talk to W2J or Sanctifier.
do u have a boost gauge in your car? check and see how much u runnin now if u have one..ent u shud be able to identify if u hvae a boost leak from that...
and well i feel it needs tuning...but also..if it is that u getting a surge u shud try like runnin less boost ...since 2 much boost and problems like that cud cause u 2 damage uh turbo and i sure u doh wah do that
Hey u could check if your intercooler leaking, a leak in the intercooler could cause your boost to spike. And apparently the evo 7 intercooler is prone to leaking after a few years of wear and tear. U can check anil he should be able to sort you out.
if u need a recirculating valve to buy i have a 1 week old forge motorsports replacement valve for the evo. it could work on the 4 straight to the 8. i goin and post it up in the classifieds and this mitsu section. if u interested call 620-1239
That sounding like the vacuum hose come off the recirculating valve. With no hose attached, it'll get pushed open under boost, and it won't open when you back off, hence the compressor surge.
so it need tuning??? or de turbo goin??
it doh hav a recirculating valve..... an it doh hav a bov either...
