Supercharged VH45DE w/porsche Cayanne intake mani dyno
Posted: Wed Jan 25, 2012 1:24 pm
So i had this vh45de in my s14 with a super charger and heard that a porsche cayenne intake manifold had the same port spacing.
So i went from this...
made these
ended up with this..
and here are the results and gains from the stock intake to the porsche intake... The power loss after 6000rpm is due to the supercharger belt slipping, i would except it to make 450-470whp up top once the belt is corrected. But no need to wonder because I'm correcting the issue now and will be back to the dyno asap to prove it. Other than that great gains everywhere in the power band about 3000 rpm
Before and after
Heres is the peak gains....
