Guest NathanMcbeath94 Posted July 25, 2016 Share Posted July 25, 2016 A bit confused with the results as was expecting higher, I know every car is different but I've seen people get more with far less and 95 octane. So that was the results and that included it getting mapped. The mods I have (most done over last few months) Turbos rebuilt FMIC Full Service Mishimoto Radiator Fully Decatted Walbro 255 fuel pump HKS FCD Blitz speed limit defender Greddy Blue Emanage HKS induction Kit HKS boost controller NGK colder spark plugs gapped at 0.8mm Blitz Nur Cat back Shell v power used on run, only even used 98/99 octane since purchase around 8/9 months ago. So was I being optimistic as I would looking for at least 400bhp from what I've read online or is that a fairly good power output for 1 bar?

mellonman Posted July 26, 2016 Share Posted July 26, 2016 (edited) Looks like you may have a boost leak mate or vac pipe leak would have been nice to see that boost curve from the start but looks to drop off fast at the transition point , your still under 1 bar of boost so if you dont have a leak your boost controller is not setup correctly for sure. Read through this thread and see your your experienceing any symptoms ^http://www.mkivsupra.net/vbb/showthread.php?35926-The-sequential-system Edited July 26, 2016 by mellonman (see edit history) Quote Link to comment Share on other sites More sharing options...
Style Posted July 26, 2016 Share Posted July 26, 2016 Yeah there's something not right when the 2nd turbo comes on mate. That boost line should flatten out at 1.1-1.2bar and stay there right through the rev range instead of dropping back to 1bar at the transition point Quote Link to comment Share on other sites More sharing options...
Wez Posted July 26, 2016 Share Posted July 26, 2016 If you look at the boost graph from 4500rpm you are not even running a bar boost, if this is BPU you should be up at 1.2bar hence the lower power figure. As mentioned above you may have a boost issue / leak... Quote Link to comment Share on other sites More sharing options...
teddan Posted July 26, 2016 Share Posted July 26, 2016 Always pressure test before dyno.. Quote Link to comment Share on other sites More sharing options...
ShawnPreece Posted July 26, 2016 Share Posted July 26, 2016 Yeah thats lower figures than you should be getting bud, when driving it do you feel a noticeable power increase and kick at 4,000rpm when the second turbo kicks in? as mentioned a few times above it does sound like a boost leak somewhere Quote Link to comment Share on other sites More sharing options...
