335i DV's

loweredram · 02-15-2011, 07:15 PM

Was wondering how many of you are running upgraded Diverter Valves? My buddy was riding in my car (I have an 07 sedan sport with a V5, UR Downpipes, FMIC, and drop in high flow air filter) He said it felt a tad "laggy " on the bottom and suggested I get upgraded DV's or a blow off kit. I can't stand the sound of the blow offs. I did some research and it does seem the stock DV's are good to around 12lbs of boost I'm assuming thats new condition(I have an 07). So would I need upgraded DV's?

Get a set of Forge DV's, gonna be better than what you have for shizzle. Although the stock should hold 14+.

The stockers have held up to 19psi on my car without issue.

I have Forge DVs. Pretty simple upgrade to insure your are holding boost. You may want to upgrade the charge pipe at the same time. I was hoping to get away with not needing to but it looks like I will be buying a charge pipe soon.

I am currently running a Stett Charge Pipe and Forged DV's, both in Black. The charge pipe on the stock car is cheap plastic and it did already crack on me. Stett sells a set for you. Most people say to get a Blow Off Valve however the N54 motor was designed to keep the air into the motor rather then fully release it.

at the boost level you are running, the stock DV's should have no problem.

What would I expect to see if the Stock DV's were not holding up? Things like lag, eratic power......etc. I was looking at a set "Hyperboost". Has anyone heard of or used these?

Hyperboost DVs look like Forge replicas. I know one guy on here (M3 Eater) advocates them in every thread but other than him, I don't know anyone else who runs these. They look good though.

You can get a set of Forge DVs used for around 140-150 shipped. I had them on my car, and to be honest, were a waste of money. Sold them and threw the stockers back on, never had a problem up to 19 psi. I believe Terry @ BMS did a test of the stock DVs up to 25 psi, and they had no issues holding up to that amount.
