Guys Ive been researching a Vortech installation on the X fire. Chips, exhaust and K&N's will always be a band aid fix for decent HP and torque improvements. Lets see $600 for chip, $70 for K&N's, $650 for a Borla (too bloody pricey for a muffler, a resonator and some s/s tubing IMHO).....thats around $1300. Get onto www.vortech.com and check out prices for a blower upgrade for killer power increases.

Vortech makes a nice blower sized for our application. Also runs heaps quieter than the normal centrifugal set up.....much less whine, very quiet. It also should fit well in our engine bay....we have the room.

I believe our engine would stand up quite well to the rigours of a centrifugal supercharger. Upgrades required for our rides would be a Bosch motorsport fuel pump (or an aftermarket one) , a boost referenced regulator to keep up the fuel demand, possibly higher flow injectors (not sure), and maybe a reduction in compression....supposed to be 10.00:1, but effective comp ratio will be around 9.00:1 because of the aluminium heads/block. Intercooling will allow more boost/power/safety but from what I've seen around 7-8 psi should be OK. Id prefer to swap out the std ECU, and run a programmable one that can be set up via a laptop on a chassis dyno under load, that way a margin of safety can be dialled in on the fuel side to prevent detonation. Ignition system should be sufficient.

The stand alone replacement, programmable ECU's are made here in Melbourne, Australia (as are MoTec) by www.autronic.com.au check out their web site its comprehensive.

Ive done some research into the centrifugal blower, there is a Vortech kit available for the Nissan 350Z that ups the output to 415HP/380ft/lbs of torque - stout numbers indeed. Id love to have that kind of performance in the XF on a daily basis, in comfort AND style. What more could you want??

Im willing to bet Vortech will come out with a supercharger kit for our cars sooner or later.....heres hoping. Maybe we could email then as a group and see what they say?

What do you guys think....

BTW....ive played with these before......u can make killer power, safely.
