Afeen Posted June 20, 2006 Share Posted June 20, 2006 Hi guys, looking for some info and help on Carbon Fibre intake systems which actually work. So far I've found this: I've found that they work really well on the BMW 6Cyl cars. Has anyone ever tried one of these? They are around £230. Your views would be appreciated.

Removed Posted June 21, 2006 Share Posted June 21, 2006 is that the Gruppe M? as for the fact if they actually work or not, well none of them do on our engine, so don't do it for power as you get any extra, do it for the noise Quote Link to comment Share on other sites More sharing options...
Afeen Posted June 21, 2006 Author Share Posted June 21, 2006 I've read this quite a few places that nothing will work on our engines. Can you explain, in detail, why please. It's nothing like the GruppeM for our cars. It's similar to the GruppeM for BMW's though. Thanks A Quote Link to comment Share on other sites More sharing options...
M13KYF Posted June 21, 2006 Share Posted June 21, 2006 It's because the ECU learns any mods and cancels them out. Unless you put on a piggyback ECU. Quote Link to comment Share on other sites More sharing options...

Unless you put on a piggyback ECU. and still after that sizeable expense, you can only expect about 20hp more from cars with intake plenum headers cats and exaust na tuning for our cars is just silly lol Quote Link to comment Share on other sites More sharing options...
Afeen Posted June 21, 2006 Author Share Posted June 21, 2006 The ECU must be working inside some really tight set parameters do be able to do this! Most modern ECU's are to some degree adaptive but this sounds like something taken to a different level. Even by passing this ECU learning factor, I'm well aware that an engine has a limit as to what kind of power it can produce. The Z may already be near this limit as it is and therefore modifcations to the headers, intake will really only change the power delivery rather than increase the output. If modifications aren;t working that well it simply means everything has been pretty well designed from factory and the Z is a well optimised. With approx 80 BHP per litre out the box it is quite highly tuned to start with. In which case - you guys are spot on, these mods are about increasing the driveability rather than out and out power. If i'm wrong in anything I say please correct me. A Quote Link to comment Share on other sites More sharing options...

A you are bang on mate, apart from the 80hp x litre. this is quite poor actually, hence why my italian colleagues insist the NA engine MUST be giving some extra hp! 100hp/L would be more like it Quote Link to comment Share on other sites More sharing options...
Afeen Posted June 21, 2006 Author Share Posted June 21, 2006 I'm so used to older cars where 100 bhp/litre is unheard of. I guess by modern standard 80 is a bit pants when we have the likes of S2000' and BMW M3's which far exceed 100. A Quote Link to comment Share on other sites More sharing options...

Chesterfield Posted June 21, 2006 Share Posted June 21, 2006 With a roadster, there is the extra 100kg to worry about too! So carbon fibre used anywhere to lighten the weight must be a good thing. That metal plenum is looking dangerously close to being replaced as part of my modding program, closely followed by that big fat air box and filter.

I dont think you,l save much weight Chris with the airfilterbox it weighs bugger all Take of that heavy standard exhaust and get a raspier one you know you want to Quote Link to comment Share on other sites More sharing options...
Chesterfield Posted June 21, 2006 Share Posted June 21, 2006 Yeah, and I could do with shedding about 25kg from the driver too! LOL. Quote Link to comment Share on other sites More sharing options...

Afeen Posted June 21, 2006 Author Share Posted June 21, 2006 The Carbon airbox is purely for noise and driver enjoyment (if you like that sort of thing). Lighter exhaust is definately a good thing as OEM Jap exhausts tend to weigh an absolute ton. What's the options on exhausts? - and I mean proper well built exhausts which have proper internals. Here's some exhaust porn for the Z: Afeen. Quote Link to comment Share on other sites More sharing options...
