MarkTheBoy Posted November 3, 2007 Share Posted November 3, 2007 Me and a mate were just talking about how installing a wet nos system would affect the level of boost on a Jspec TT BPU. Mine for example runs about 1.1 - 1.2 ish and has a restrictor ring fitted to prevent it from climbing over this. Would running nitrous increase the level in which the car boosts to? (ignoring the fact that the restrictor ring would prevent it) Just wondering... anyone got any ideas? Quote Link to comment Share on other sites More sharing options...
JohnA Posted November 3, 2007 Share Posted November 3, 2007 .... Would running nitrous increase the level in which the car boosts to? ... You'd have a lot more exh gases produced, so you'd see higher boost figures if you don't make mechanical changes (boost controller, wastegate spring perhaps) Have a look at the Wizards of NOS forum, they know the subject intimately.

MarkTheBoy Posted November 5, 2007 Author Share Posted November 5, 2007 I had a look on there but couldnt see anything relating to the results of adding nitrous to a turbo system. I'll have another look and see if I missed anything. Quote Link to comment Share on other sites More sharing options...
JohnA Posted November 5, 2007 Share Posted November 5, 2007 Mark, that's all they do! It would be the best place to go for the first layer of empirical information, so you can avoid making 'newbie' mistakes that could cost you the engine.

Loads of other really usefull information though... those guys really know their stuff! Quote Link to comment Share on other sites More sharing options...
kylestt Posted November 9, 2007 Share Posted November 9, 2007 Its going to vary per application but the likely hood of your boost increasing is there. It may increase just SLIGHTLY or it may spike way up. Depends on the amount of nitrous your adding as well. Best thing to do is when your ready to spray the nitrous, do it on a controled environment like a dyno so you can quickly get out of the gas if you see something not proper. Goodluck and keep us posted! Quote Link to comment Share on other sites More sharing options...
JamieP Posted November 9, 2007 Share Posted November 9, 2007 It does make the car boost harder when on Nos, really needs to be setup by someone that knows what they are doing on a dyno imo, had mine so it retarded the ignition by 2 degree when activated to stop it running lean.

Retarding the ignition has nowt to do with how lean or rich it runs In this case pulling some timing counteracts the artificial raising of the compression ratio that nitrous causes and avoids detonation from that source. -Ian Quote Link to comment Share on other sites More sharing options...
