This if my first post here, so I'd just like to say hello. Thought I'd start it off with a good note: a blowoff valve. I wrote up a big long thread about it, and then when I went to send it somehow it got erased. So after much frustration and mumbling under my breath, I made one picture for the whole install. Sorry for 56K users, but it's the easiest way to do it. We installed a GReddy Type-S blowoff valve on my friends 03 Evo 8 today. I know he is around here somewhere, so if you read this Art - come in and say hi! Hope it helps...



I hope this helps to anyone who might be considering doing this install. It took about 30-40 minutes total, including a phonecall to Road/Race to check one thing, and looking for wrenches. Good luck!

Nice write up!
Is it considerably louder then stock when recirculating?
Also does it sound like wooshing air when recircing or does it sound like the signature greddy chirp?

 

Thanks! It is definitely louder than stock. When partially on the throttle and then letting off, there is the nice GReddy chirp, and if you really get on it.. you hear plenty of wooshing (most of this is from the intake though, I'd imagine) and then the BOV really rips. It sounds great! We couldn't wipe the grin off our faces after it was installed

 

Sweet!
I have one on order

 

Nice! Good luck with it. Hopefully my writeup helps

 

where did you buy it from, that it came pre-adjusted?

 

From Road/Race Engineering:

http://www.roadraceengineering.com/evo.htm

It's $230 for the kit. It includes the adapter, too.

 

so no stalling or idiling issues whatsoever with RRE's kit?

 

Nope! When you're in neutral or just idling, it stays at a consant 900~ rpms or so... No bogging down or anything.

 

How about surge??? Do you get the bucking effect?? at part throttle?

 

bump for an answer!

 

your not going to see any stalling or idle issues with recirc valves, There should be no compressor surge either if its adjusted properly.. I'm jsut surprised they adjusted these before installs... COOL

How much PSI is the valve good for? actually i should say spring...

 

i love my greddy..... on partial throttle you get a lil chirp....but when " getting in it" and shifting you get a nice "back up b*tch" WOOOOSH........ i have a spring removed and i have no stalling issues or anything and yes i recirced... and its still loud.

 

i guess 20psi+ since the guy above me has his set to 20.

 

Whats diff between the regular Greddy Type S BOV vs the RRE one??
