I know there will be more power but what about the torque and power at change points.
Planning to fit them but don't want to mess it up for towing or have a hole when changing gear.

i think they reduce the torque at the bottom end but great for higher up the rev range martin!

Hoping that someone has done it - if I lost torque around 3000rpm to 4000rpm it would be slower not faster.
I have an auto and I tow as well

in low rpms torque values must be lower :-/

high end will not be useful unless you drive a manual..

Best to wait for MarkDTM's findings with the Countess' 2.6 IMHO.
Conventional tuning theory says hotter cams shift the torque further up the rev range to get more power but, for example, if the difference is in cam lift rather then timing / duration, you may lose very little low down. :-/
It's quite possible that the 2.6 cams are mainly different in lift because it would have allowed them to keep the intake charge velocity high, giving better emissions. Until someone measures both types of cam, it's a guessing game, though.

agreed..
and there will be another side effect like increased consumption (hoping not) :-/

I have had an offer at a good price, and just want to be sure before coughing up.

They appear to be slightly higher lift and little else.
So the torque curve should remain pretty much the same at lower revs.

Get the lower inlet manifold to (the plastic bit).....its got slightly larger ports on it

The bills getting bigger ;D

I think I should be getting preferential rates and commision at this rate!

How much larger?

How much skimming can I give the heads?
Target would be 11.0:1 compression but anything is a bonus.
Again emmisions don't care except for MOT, and fuel consumption - will be on LPG.
I normally use LPG and BP Ultimate

Bugger all in reality....its a V engine so would affect inlet alignment.
The compression drop on the 2.6/3.2 is achieved with dished pistons!

Damn - I have used 60 thou skimming before on an engine to raise compression, gave an extra 10bhp at the wheels ;D
I suppose inlet dividers could be modded if necessary

head skimming will increase torque directly in all RPMs..
so worth it..but really expenses seem to increase ;D
I remember a similiar story :-X
