Quick restrictor ring/boost question

Recommended Posts

I'm planning to fully de-cat the car and run 1.1 - 1.2bar. Question is, having a boost controller that has a high and a low setting am I better off getting a 0.9-1.0 bar restrictor ring then using the boost controller to be able to increase it a bit, or will it run better/differently with a 1.2 bar restrictor ring and basically not using the controller at all?

Mate, if you already have the boost controller installed - get a 1 bar restrictor ring. This is what I do with my car and have a Apexi AVCR. I normally have it switched off (1 bar). When I fancy a play/race I switch it on and get 1.2 bar, turbos spool quicker and earlier in the rev range too. I think it's better than permanent 1.2 bar as you soon get used to it. Keeping it at 1 bar most of the time and then switching to higher boost makes the car more enjoyable IMO

Ideally you want a restrictor plate that'll give you about 1.1 to 1.2 bar on the coldest days and then use an EBC to bring it up to the level you want (between 1.1 and 1.2bar) the rest of the time. That way you'll always have the maximum safe boost available without going over the safe limit when it's really cold out.
