wallis Posted June 22, 2010 Share Posted June 22, 2010 In the process of resorting out the set up on supra I have a rr fitted and it boosts to 0.8 I'm getting a new boost controller fitted Friday and was wondering if I can leave the 50.5mm rr in and still boost to 1-1.2 bar or do I need to take it out?

Matt H Posted June 22, 2010 Share Posted June 22, 2010 Do you have both CATs out? If so, I would leave your RR in and let the boost controller up the boost to 1.2 bar. If you take the RR out, your boost might spike to undesirable levels. A boost controller can only up the boost, it can't decrease it, so leave the RR in if it's at a nice stock 0.8 bar now. Then when you want 1.2 bar, you can use the BC to up it Quote Link to comment Share on other sites More sharing options...

Then when you want 1.2 bar, you can use the BC to up it perfect I was hoping I could leave it in, the car had some work done 3 years ago when I went bpu it seems I had a dodgee boost gauge that was Reading 1bar but that was actually 0.8(stock boost) I was also told a fcd had been fitted, which I found out on Sunday actually hadn't! I have a double decat with a 50.5 rr fitted in sec decat section which restricts to 0.8 bar which I guess is perfect for normal driving and I will now be able to increase boost to 1.2 with the new controller and fcd which is being fitted on Friday and next Thursday it's going to be on the rolling rd at Boston for some dyno readouts :-) Quote Link to comment Share on other sites More sharing options...
