Hello guys,
I just got the car back from Nizpro.... did the intake pipe and they have done a great job... and it surely does look very nice!!! And guess what?! THere is absolutely NO power gain at all from this gain (which I have sort of already expected because the plenum/throttle is not changed), but love the look of that...
The intake consists of:
1. 84mm bore diameter intake pipe with integrated MAF sensor (SS)
2. Aluminium bell mouth (a lot larger than the standard piece and down to 84mm)
3. Silicone hoses and clamps
4. Modify airbox to accommondate larger bell mouth...
I even lost 1 rwKW at the maximum rpm and a few rwKW in between 2680rpm all the way to 5000rpm and the rest of rpm ranges stay roughly the same... Simon from Nizpro says that this does not indicate the car actually loses power, but he would say it stays the same as the dyno conditions weren't the same (16/06/2005 vs 13/07/2005)... there is always a few kw gain or loss here and there sometimes when you re-dyno on different days...
So I guess most of the intake in the market should be roughly the same and the power will not change much unless you have changed to a larger throttle or a plenum since the amount of air going through the throttle is the same anyway plus there is no extra pressure to push the air into the throttle with just an intake....
Here are a few pics and enjoy them!
cheers,
