Chris and Alana Posted October 29, 2007 Share Posted October 29, 2007 Hi guy's, I was just thinking about something the other day. If you put a rr in the exhaust (after decat and performance exhaust) to give you stock boost 0.8-0.9bar, then you install an EBC to raise boost to 1.2bar, will this create more stress on the turbo's and give you higher EGT's than if you had a rr allowing 1.2bar to happen naturally?

Gerry Posted October 29, 2007 Share Posted October 29, 2007 Good Question... don't know the answer but I'm sure many will (lets hope you don't get seven different answers) ! Most people seem to recommend a 1 bar rr and then a bc to up to 1.2 bar when needed, seems sense to me, as when pootling about, 1 bar would be fine for me, but would like 1.2 for Sunday morning runs....

hodge Posted October 29, 2007 Share Posted October 29, 2007 Hi Chris. Hope your well young man. Funny enough mate ive just got a 1 bar ristrictor ring from CW and my plan is to run 1 bar for normal driving and 1.4 bar (hybrids before anyone jumps all over me) on my overtake boost with the E-01 boost controller. I shall check my EGT before and after and let you know. I dont know anyone who does .9 bar ristrictor rings as I think I asked when I was considering it myself. I'll keep you posted fella.

Chris and Alana Posted October 29, 2007 Author Share Posted October 29, 2007 Thank's guy's, the reason I ask is that I would like to have stock boost for reliability and help on fuel for most driving (boost controller turned off) and then have the low and high settings at 1.0bar and 1.2bar. it just gives me a nice varied level of boost to chose from depending on how I feel like driving oh, thought I would mention I still have my second cat in and when I got a 1bar rr it held boost to about 0.9bar to maybe 1.0bar in the cold of winter. I know there is little restriction from the second cat because when I first got my nur spec on and first decat I way overboosyed to 18-20psi before the rr so I know it will reach 1.2bar ok. Anyway I was just wondering if this caused more stress on the turbos as instead of naturally being allowed to create boost they are being forced to create more and this must have an effect on the turbo life and egt's. Anyway, look forward to your experiences hodge. Link to comment Share on other sites More sharing options...
