MBC Hooked up...questions.
Yes...I have searched...
My mods:
HKS Cat back
HKS RS intake
GReddy Type S BOV (Single spring)
TurboSmart MBC
Car:
Evo IX MR
Ok...so, I have searched. Never used an MBC before always used EBC's. Enjoy the fine tuning of EBC's but I decided to go with the MBC this time. Read a couple of write ups and what not. Basically, this is my configuration: Factory boost control lines taken out and the BCS just looped closed with a single piece of SVH. The nipple on the intake is plugged. Simple and straightfoward, the MBC connected right with one side going to the WG and the other going to the compressor nipple.
No worries. Boosting and holding 1.4bar all day long. Goodie. But I am getting more flutter and say I am driving in 4th at about 1bar and 3/4 throttle, I let off, I can really feel the car let off. DOn't know how to explain it...Feels like the engine moves. Almost like too spongy mounts. Maybe it did that before but I don't know. I am just noticing it tonight. The flutter I can deal with as I think that the single spring in the BOV is just too light. I have never heard of the single spring deal until this car and it just seems hokey. Even though I know the JDM BPV will work just fine, I like the sound of the Type S.
Am I just being goofy because of the feeling of the car? Is it because I am running a MBC? Should I toss a restrictor pill in there? I am sure that mechanically, things are cool...Just some quirks I am learning about with the Evo. Any help would be cool.
