HP vs VCT

[sleekism]

I was having a chat to a mate who has a XH XR6 ute with the XR6 HP motor modded with NOS and a supercharger and I responded that since his was the HP and mine is the VCT with the same mods mine has the potential to make more power.

The Tickford Sixes don't seem to have the same information as other engines on the internet so I'm not sure if my statements are justified.
I mean is the VCT motor based on the HP with the addition of VVT or is it based on the lower Intech motors basically does it have the same air flow characteristics as the HP?

Also is the HP motor the same as the EF/EL with the larger ports or is it based on the AU small port motor?

What does Tickford actually do to the Intech motor to increase power and torque ?

How much can the valve timing be changed in the VCT motor and is there are aftermarket support to cahnge the valve timing and what sort of power can be made?

I have heard some people say that the VCT was added for fuel economy not extra power but seeing as Ford officially rates fuel consumption higher in the VCT over the HP this seems stupid.

I have seen the results Casper has got with his VCT but has anyone done this with a Fairmont Ghia?

I am currently booking in soon for 2.5 inch cat back and a bit further down the track Pacemaker extractors what power figures can I expect to make and how much performance would I gain?

I have heard that fitting an XR6T snorkel helps but looking at the intake it doesnt look that restrictive would I gain any power from it?

I'm looking for around 7.5 to 100kays and low 15 quarter miles at a good price but would probably look at different diff if need must be also would it be too difficult to fit XR6 shocks to my Mont and would it improve handling?
