pistonbroke Posted July 14, 2009 Share Posted July 14, 2009 Have you got a restrictor ring in there? Quote Link to comment Share on other sites More sharing options...
Lee_e Posted July 15, 2009 Author Share Posted July 15, 2009 yes i do , forgot to put that on the list [OOPS][/OOPS], its a 1.2 bar ring. Quote Link to comment Share on other sites More sharing options...
Guigsy Posted July 15, 2009 Share Posted July 15, 2009 seems like a low number :S i assume thats flywheel? Quote Link to comment Share on other sites More sharing options...
wkdtime Posted July 15, 2009 Share Posted July 15, 2009 I see you have the RR fitted, but what actual boost were you seeing on the dyno? l Quote Link to comment Share on other sites More sharing options...
Lee_e Posted July 15, 2009 Author Share Posted July 15, 2009 not sure on the boost levels yet but all will be clear when i pick up the data sheet in the next couple of days. he said it was running 1.1 bar but ill believe it when i see the graphs it could be flywheel or rear wheels im not sure, i will just have to wait untill i collect the data.

Thorin Posted July 15, 2009 Share Posted July 15, 2009 345RWHP sounds about right for 1.1 bar to me. Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted July 15, 2009 Share Posted July 15, 2009 You just need a boost controller in there now then. May I also suggest you get a boost gauge so you can see what it's doing. Or even better, the AEM tru boost (which I have) is a boost gauge and controller in one Quote Link to comment Share on other sites More sharing options...
Thorin Posted July 15, 2009 Share Posted July 15, 2009 You just need a boost controller in there now then. I'd leave it as is, if it's hitting 1.1bar now then it's quite possible it will be hitting higher than that in cooler weather. A boost gauge is a must if you haven't already though. Be happy with it as is, that extra 0.1 isn't going to make a great deal of difference. Quote Link to comment Share on other sites More sharing options...
danhicks22 Posted July 15, 2009 Share Posted July 15, 2009 With a 1.2 bar RR in, is it possible to lower the boost below that with a boost controller? Or will a boost controller only raise? Quote Link to comment Share on other sites More sharing options...

Only raise the boost, you could always fit a 1.0 RR and then raise the boost to 1.2 for those sprinted moments. Quote Link to comment Share on other sites More sharing options...

That was what I thought, but a guy at my garage said that's only the case if I run the stock solenoid alongside the one with the controller and that if I remove the stock solenoid, I can control it both ways. Didn't sound right to me but I don't understand enough about this stuff to know why. Quote Link to comment Share on other sites More sharing options...

danhicks22 Posted July 15, 2009 Share Posted July 15, 2009 You need to find a different garage Bit awkward now, they're building me a custom exhaust with sports cat next week. I'll just make sure they put the RR in when they do it. Whereabouts should the RR go, or does it not matter? Quote Link to comment Share on other sites More sharing options...

Id place it where the De-cat pipe meets the exhaust, that way you can easily change it if need be Quote Link to comment Share on other sites More sharing options...

danhicks22 Posted July 15, 2009 Share Posted July 15, 2009 If you're putting a cat back in you won't need the restrictor. Won't that depend on how restrictive the cat is? What I'm having is custom front decat, high-flow cat in place of the second cat and Envy GT Evolution cat back, with 3" piping all through. Is it not better to put one in just in case? Presumably I won't know if I'll need one until it's tested? Quote Link to comment Share on other sites More sharing options...

For some reason I didn't really think of it like that. Thanking you, sir. You're a gentleman and a scholar Quote Link to comment Share on other sites More sharing options...
