Guest Artermis Posted March 1, 2008 Share Posted March 1, 2008 Ok I'll try it without the RR in. I know as was mentioned previously that RR's aren't an exact science. But it's a 1.2 bar Envy RR that's in place so thought I'd at least see it hitting 0.9 of full boost. if my math is right its only about 1.5 psi to 0.1 bar, so the difference between 0.8 and 0.9 is pretty small. we dont wanna be annoying, but the biggest veriable right now is the restrictor ring and its probably one of the easiest things to check and eliminate. if you take the RR out and you still only getting 0.8bar then you know its a different problem. worst comes to worst you take the RR out, bury the loud pedal in the bulk head and go flying faster than you've ever been before and still only read 0.8 you know the gauge is duff.

Guest MaTTi Posted March 2, 2008 Share Posted March 2, 2008 Why do you even worry about the gauge showing right or wrong values, you should be able to decide if its on 1.2 or 0.9, its supposed to be a big difference. Keep us posted when you find out the solution. Quote Link to comment Share on other sites More sharing options...

Solid Snake Posted March 3, 2008 Share Posted March 3, 2008 Have you tried adjusting the settings on your boost controller? It may be set at 0.8 maximum. If you have an e-01 let me know your setting and can compare them to mine. Andy Quote Link to comment Share on other sites More sharing options...
Solid Snake Posted March 3, 2008 Share Posted March 3, 2008 Which boost controller do you have and do you know what the settings are? It may be set at .8 maximum boost. If you have Greddy e-01 let me know your settings and I`ll compare them to mines. Andy Quote Link to comment Share on other sites More sharing options...
JohnnyW Posted March 3, 2008 Author Share Posted March 3, 2008 Hi Andy, I'm not running a boost controller at the moment. I've got hold of a stock airbox so will be fitting that as the induction kit thats on it looks cheap and crap will also try removing the RR will see if it makes a difference, not holding my breath though.

JohnnyW Posted March 4, 2008 Author Share Posted March 4, 2008 Alrighty time for another update. Managed to get a stock airbox (Thanks Sedge) fitted it tonight. They're a bloody tight fit aren't they! Another one of those two minute jobs that turns out a lot longer. It's now boosting slightly higher than it was before but still a good bit away from BPU levels. Guess the next step is to remove the RR and see what affect that has. Good to get the stock airbox on though, feel a lot happier now i'm rid of that pile of sh!t that was on there before. Temps seem slightly lower and boost is slightly higher so that's definitely a good thing Quote Link to comment Share on other sites More sharing options...
JohnnyW Posted March 29, 2008 Author Share Posted March 29, 2008 Another update removed the restrictor ring and it's now boosting at 0.9 bar. Definitely a lot faster but still not reaching the magic 1.2 bar figure. Anyone got any suggestions? I'm totally stuck on this one now :-( Quote Link to comment Share on other sites More sharing options...
jaymdee Posted March 29, 2008 Share Posted March 29, 2008 You said in a previous post that the Apexi exhaust may need replacing. It's possibe it's collapsed in the middle causing a big restriction Quote Link to comment Share on other sites More sharing options...
JohnnyW Posted March 29, 2008 Author Share Posted March 29, 2008 Yeah it's been replaced. Really stumped on this now I have no idea what could stop it reaching 1.2 bar, state of play at the moment is: FCD Envy decat pipes Motoria 3" catback exhaust Walbro pump Stock SMIC No restrictor ring Iridium plugs Quote Link to comment Share on other sites More sharing options...
vvteye Posted March 29, 2008 Share Posted March 29, 2008 No idea mate but when I was BPU I did have the HKS boost controller as part of the set-up. Funningly enough I've just updated this on the forsale thread Quote Link to comment Share on other sites More sharing options...

QSC Posted March 29, 2008 Share Posted March 29, 2008 A boost controller can't increase the level of boost unless the car is already capable of reaching that level on its' own - just ask Andy Hannah - Quote Link to comment Share on other sites More sharing options...

letmeshowyou Posted March 30, 2008 Share Posted March 30, 2008 Definite fail - that's not true. I'd suggest getting a boost controller - if you don't want to invest in an electronic one to start with, try a manual one to see if it helps - you can pick these up for about a tenner so no biggy, and could change to an electronic one if it works out. ps. are you sure the second turbo is coming on?

JohnnyW Posted March 30, 2008 Author Share Posted March 30, 2008 2nd Turbo is definitely kicking in, I've got the whiplash to prove it Love the difference in the car after decatting, soo much more responsive and quicker spooling. Even at just under 1 bar the power difference is phenomenal I'm desperate to get up to 1.2 bar to see how insane it is Quote Link to comment Share on other sites More sharing options...
QSC Posted March 31, 2008 Share Posted March 31, 2008 Sorry QSC... but that was funny. I said ask Andy Hannah - I don't pretend to understand how these things work - ask him - seriously. Quote Link to comment Share on other sites More sharing options...
QSC Posted March 31, 2008 Share Posted March 31, 2008 Is that what Andy told you? Mike Yes - it is. He had my car in for two weeks - fully decatted but only reaching standard boost level with an EBC fitted. The only way he could get it to boost any higher was to fit a less restrictive exhaust - in other words, the EBC couldn't increase the level of boost because the car wasn't capable of reaching that level without the EBC. If you know different and can prove it, I will gladly pay you to sort my bloody car out, because I have spent a reasonable amount of money trying to do this already to no avail.

Thorin Posted March 31, 2008 Share Posted March 31, 2008 A boost controller can't lower the amount of boost a car is producing naturally, but it can certainly raise it. If not you're doing it wrong Quote Link to comment Share on other sites More sharing options...
JohnnyW Posted March 31, 2008 Author Share Posted March 31, 2008 Interesting..... not being too technically minded can someone explain how it manages to do that. I'd have though since it was decatted, running no restrictor ring that would be mine running as high as it could go. Quote Link to comment Share on other sites More sharing options...
QSC Posted March 31, 2008 Share Posted March 31, 2008 This is the point though isn't it ? Think about it logically - you buy yourself a standard car & you want to increase the performance, so the first thing you do is all the BPU mods, the main one being to remove the cats in order to allow the boost to increase. If a boost controller is capable of increasing the boost to whatever level you desire, then why does everyone remove the cats from their cars if it is not necessary (and thus technically making them illegal to drive on our roads) ?
