And yes will retain the same engine type (MSP) with some select modifications.

Same one I am running now - Adaptronic 440 Select (Stand alone).  I already scaled the maps for a bar of boost I just don't use that region at the moment!

Ah didn't know you had that. Well all things being equal, same temps etc and one bar of boost you should double your hp hopefully.

The saying goes if you want to go twice as fast then you need four times the power

It all depends where you start and end...  The problem is (assuming nothing else changed) as the air speed increases so does the drag exponentially, the faster speed you got to, to start with, the more power you need to go even faster.

A generalised drag equation look something like this:

Drag = Cd x (d x V^2)/2 x A

Cd is the co-efficient of drag that is a constant the represents the slippiness or otherwise of the object it does change unless you change the aero
d is the air density (That does not change by much)
V is the velocity and is squared
A is the area of the body referenced (also constant)

So that pesky speed has an awful lot to answer for and gets exponentially worse the fast you go... booo!

Yeh, ends up like your driving through treacle. That's why the Veyron needed another 200hp to go 10mph faster I think

Yep and the Veyron had significantly better Cd than me!  I would not be surprised if I added 200hp that I only got 10mph as well (and I'm starting at a far lower speed) given the rubbish aero the car has.

Wonder how much better the airflow over the car would be with a proper wind screen an a roof panel?

So so good to see you out enjoying the car, a car that is a credit to you due to the build quality you have achieved.
All the best Clive

Yes, I did have a westfield aero kit but got rid of it due to it being too ugly to put up with!  It's interesting that yours gets figety over 120, I was at 135 and apart from my head being ripped of my shoulders the car was as planted as it is at 20mph (this might be a slight exaggeration).  Do you run a chin spoiler on the nose? and a rear diffuser?
