Finally BPU


Class One

Recommended Posts

Well after two and a half years ownership and about 18 months of procrastination, I've finally done it and gone BPU.

 

Firstly I'd like to thank Sam & Greg at Turbofit for their advice and patience and their team for doing the work. I'm very happy.

 

So I'm running a 3" double decat, 4" Trial Racing sport S/S exhaust , 1.2bar restictor ring and one of those XS Power FMIC's, colder plugs and a walbro uprated pump.

 

I can only run upto 1 bar as I don't have a FCD fitted but it certainly seems to spool up a tad quicker and feel a spot more lively. I've hit fuel cut a couple of times, but only at serious leptons though, for normal driving it hasn't really been an issue.

 

:cool:

so when u take the restricter ring out she will automatically run to 1.2 bar? well done anywho im about to get my bpu going and finished in the next month :D

 

Nope....once the cats come out, the reduction in back pressure takes the boost over the limit of the stock wastegate, the restrictor add's some back pressure so the boost can remain at a constant 1.2bar or there abouts hope that makes sense
