I am currently in the market for an evo and naturally im reading forums and reviews etc. about aftermarket parts. I dont know much about turbos etc. as my previous car was a chevy suburban.

I was wondering if anyone had any suggestions about whether i should use a blowoff valve or a bypass valve because i have been reading a lot about blowoff valves leaking and the process to fix it etc. and of course i love the noise it makes and the attention it gets . Thanks!

 

And if if you say blowoff valve, any recommendations?
Thanks again

 

The stock works and holds fine for stock boost levels. Some leak, some don't. They are plastic.

A viable upgrade is upgrading to the 1st gen DSM BOV, cheap and effective.

A diverter valve is a valve that recirculates back to the intake (still a blowoff), you're thinking of. Blowoff valves that vent to the atmosphere cause a rich condition in shifts due to the misread from the MAF sensor and can cause poor idle, stalling, etc.

 

do you know what the some of the best models would be because for some reason this is something im not hesitating to spend a little extra money on.

Thanks for ur response
