There is a lot more to a car then just 1/4 mile times and terminal speed.

Yes our cars may be faster in a straight line, but I really think that those who believe that the current Ford and FPV offerings are better then the new HSVs are kidding them selves.

Had a read through that.. Was quite interesting.. But alot of Word of Mouth. Still waiting for the dude tuning it to actually stick something concrete up.

Without stirring up the fanboi's can someone answer this to make sure my head is on the right track.

A supercharge makes power dependent on vehicle RPM.. Ie: similar to NA power will climb with rev's constantly. Turbo makes power up to a predetermined level of boost which can be as low as 3000 rpm then it maintains that power all the way out to the shift point?

So needless to say a turbo is making max power for half the rev range of a gear.. While a supercharger may only make max power at or just before the actual shift point?

So therefore if an excel spreadsheet downloaded off the internet with a formula determines that for 348kw you should run 11.9s @ 122mph.. (Guessing here) and that formula matches a turbo car.. Technically that formula can't be applied to a supercharged car because the variables are actually different?

I can't get my head around how something rated at 310kw can match it with something at 430kw.

Don't get me wrong, beautiful car nonetheless but for the price tag sheesh.

Yeah that's my understanding. Ratter I think posted up in another thread about the area beneath the curves giving a better idea of a car's power performance. Definite integral I think is the term. I trapped at a highest of 121mph, the 11.9 was 120mph with about 320rwkw. Poor 60 footer affected ET though.

I'm pretty sure that the more linear dyno charts (NA or SC) usually trap at lower mph compared to our turbocharged cars, for a given speed (ignoring the many other variables of course). I'm still scared that they will be faster than I am even with a lower mph.

And yeah tune only they will destroy me I expect. Tune only miamis are as fast or even faster than my theoretical best of 11.7/11.6 ish.

Through reading that HSV thread from what I understand they got about 400rwkw with just a tune which is wild... but.... XFT tuned a miami the other day with just a tune and cracked 428rwkw I believe.

The HSV is a better overall car but for the same money you can buy a GT and get it going quicker and handling better than the HSV.

I get to drive the A45 and CLA45 when it hits our showroom next week! Can't wait

If you're talking about the CLA45 it's 265kW and 450Nm
