The Evo VIII BOV starts to leak past 19/20 PSI of boost. It would be a good idea to get one

Ahh, sorry for spamming! I bought a standard MBC from AMS and am having it installed now

If I do purchase a IX bov, would I have to have the car retuned?

Sorry for all the questions

 

Good call. Even with the advances in the ECU based boost control I feel like a lot of pro tuners aren't using it. Too difficult to dial in and time consuming maybe?

Anyway a MBC is a solid way to go and it super simple to install. Cheap too.

 

ams will sell u the parts for u to get your 300 hp.

 

No you don't need a retune for a BOV. Get a boost gauge tho. Make sure no boost leaks and change plugs.

 

my car was done by ams and they are amazing. they have mbc and ix dv's so just get that before your car is tuned and have the boost set to 25pounds and maybe youl hit 300. if your lucky ;P good luck

 

Chris@Ams will take really good care of you.

 

Hahahaha, the AMS tech working on my car came in and asked if I wanted to upgrade to the IX bov Which I did, so let's hope for some good numbers!!

BTW, I have. Boost, Wideband and oil pressure gauges

 

with just those mods, i doubt you'll come near 300 without a MBC. Good Luck, I hope it goes well! They will take care of you.

 

well keep us updated cause you are the closest to my setup and i want to know how much power the car will make with those upgrades.

 

That information is wrong, if that was true then at peak boost of 19.8lbs stock, I would loose boost. The plastic BOV leaks around 25-26psi. You may not need to upgrade it depending on where they set the boost at, but it would not be a bad idea to just do it, and you will not need a retune just for the bov.

 

In for your results

 

I couldn't get much more than 20psi into mine on a boost leak test. I changed it out for a IX (JDM MR at the time) and it holds 30 fine

 

Hey, can you go peek around the shop for that GT-R they are building?

 

I saw it earlier this morning outside with no front end. Said "worlds fastest GT-R" with a 10 second time on it
