Cars you’ve smoked ?

[LenEV2016]

My schoolgirl maths suggest that going from 225 to 325 bhp is an increase of 44%. Whereas from 435 to 535 is only an increase of 23% . So in terms of putting extra load on the ancillary components, surely the 435bhp to 535bhp is a milder upgrade?

It's how a car already on the limits in terms of current performance of chassis/suspension brakes performs without adding an extra 100bhp, and it's the 535bhp you mention that will push the car beyond it's limits.

Show me a car out there with that power output that doesn't have massively uprated brakes and suspension
If there wasn't a need for vented discs etc they wouldn't exist.

Which goes back to my original post if you are going to bump up the power is the cost of bringing everything else up to a standard to cope with that worth the extra performance over what is currently a decent enough driving car with blistering straight line speed.

Apples and oranges thing, it all depends where you're starting from.

Percentage increase from the same base is relevant, but from different bases, it's meaningless.
