Steve W Posted April 1, 2003 Share Posted April 1, 2003 WELL, I think everyone says ~1.3 for STANDARDS, but not sure if you can use more with hybrids ? ? (I would think it's the standard Turbines / wastegates which are the problem - 'boostwise' that is ?) FatS.

Darren Posted April 1, 2003 Share Posted April 1, 2003 435bhp on standard turbos? I think the remapped ECU could make this possible from what ive read and with the other mods you have. But the best thing to do is take it to a rolling road and do a power run..this will give you BHP figures and more importantly will check your fuelling etc is correct. You dont want any engine damage do you?!! Most people run at 1.2bar on standard turbos. Is that the black car out of Japan performance?

Adam W Posted April 1, 2003 Share Posted April 1, 2003 1.2 bar to be safe, 1.3 bar max I think. The j-spec turbos are quite "fragile" as standard, they're spinning so fast and getting so hot at those boost levels the blades have an unfortunate habit of flying off If you want any more power than that you need hybrid turbos (to get more air in) and Uk spec 550cc fuel injectors/pump/resistor pack (you can't force all that extra air in without fuel to match or there will be BIG problems!).

Guest Terry S Posted April 2, 2003 Share Posted April 2, 2003 I'd be worried about the longevity of the ceramic turbos above 1.2 bar. Quote Link to comment Share on other sites More sharing options...
Terminator Posted April 2, 2003 Share Posted April 2, 2003 Originally posted by Terry S I'd be worried about the longevity of the ceramic turbos above 1.2 bar. When taking out both cats on a Jspec, the max bost level varies from car to car. AFAIK most of us have to leave a cat in or stick in a restrictor to keep boost safely below 1.2 bar when running a free flow exhaust system.

Suprash Posted April 2, 2003 Share Posted April 2, 2003 Originally posted by Terry S I'd be worried about the longevity of the ceramic turbos above 1.2 bar. But I know in the back of my mind, now that Im de-catted and running max 1.1bar, that my J-Spec turbos are going to be shortened in life span, just because they were designed to run at that level, thats why if you de-catt you shoud have little pot of money put aside, becuase as far as Im concerned that day will come when they decide to go whiiiiiiiiiiiiiiiiinnnnee...........Its just a matter of time.

Guest Terry S Posted April 2, 2003 Share Posted April 2, 2003 There are cars out there that have run that kind of boost levels on ceramics & lasted, it's just that IMHO if you raise the boost significantly past stock levels then sooner or later the ceramics will give up the ghost. That is when it makes perfect sense to buy hybrids rather than plough money back into another stock set. Quote Link to comment Share on other sites More sharing options...

Guest Terry S Posted April 3, 2003 Share Posted April 3, 2003 The damage is about about 2k for a set of hybrids;) Shouldn't damage anything. If they go because you drop a plug though this may well have caused damage on the way through. Quote Link to comment Share on other sites More sharing options...

Steve W Posted April 3, 2003 Share Posted April 3, 2003 Thing is, I've heard (even SEEN) the stories of turbine blades being embedded in the cat... WHAT HAPPENS TO THE BLADES IF YOU'RE DE-CATTED ? ? BYE-BYE following car's windscreen ? ? ? Quote Link to comment Share on other sites More sharing options...

I wouldn't worry about that, quite a few cars have survived my jetisoned exhaust baffle. Quote Link to comment Share on other sites More sharing options...
