Hello,

 

wondering if anyone has designed a single plenum? Something which looks a bit like this:

Would be keen to hear if anyone here in england makes them.

 

Cheers.

Not in the Uk, no, None available "off the shelf" so to speak anywhere, although the likes of JUN have the designs to manufacture.

 

Might be worth having a chat with John Dixon if your Seriously interested, as he has designed and had manufactured a new Intake plenum, albeit for his Vh45de V8 transplant into the Z32 using individual throttle bodies....but he has the knowledge and the contacts to make it happen.

Wasn't Mac1 having one fabricated a while back?

I remember NitroPower in Cyprus putting a piccy up of an highly modded Escort fitted with a zed engine that had a single plenum but i think it was a home made jobby :confused:

in what way are these advantageous? I was under the impression that nissan spent a considerable amount of time designing the stock plenum for best power delivery?

Obviously depending on the design but the general consensus is that aftermarket plenums help bhp but reduce torque!

Its more to do with the stock plenum becoming a restriction at very high power levels.

 

I doubt you would see any gains with a current output below 600/700hp

 

Although changing to an Individual throttle bodys and custom intake could prove to have its advantages even in a mildly tuned state.
