power to weight classic vs newage
Hi all not looking to start a power war as we know the classic in standard trim is much lighter than the newer cars what difference does this make ie power to weight in a straight line what extra power wud the newage car need to have to be equal?

Granted i get what your sayin have you Dyno tested both cars that's what im trying to work out your classic mite be less powerful etc I've heard it cud be around 50bhp but this cud be nonsense but there must be a golden figure physics etc lol

BHP divided by weight (Kg's) multiply by 100 gives you your BHP/ton
So, for a typical classic STi 280/1295x100= 216BHP/ton
Typical New Age 1495Kg's
BHP/ton calculator
BHP/ton Data

So to complete that if the newage at 1.495tonnes also had 280 bhp it would have a power to weight ratio of 187bhp per tonne or 15% less.
That ignores torque differences, power delivery, chassis benefits, etc but gives a rough guide: " you'd need 15% more power in a newage to match a classic in ooomph" e.g. a 322bhp newage = 280bhp classic, or 500 newage = 425bhp classic

Thanks guys what i forgot to mention was forget gear ratios just power to weight for example my 95 wrx is 1230kgs and started life at 260ps the same year sti is 280ps but 65kg heavier what was the 0-60 times for both models etc

There is more playing a part in this debate than peak power vs weight, gearing, area under the curve (power delivery), torque, just examples but you get where i`m going, JDM newages make these thing even more pronounced. Yes, as a rule, classics need less power to achieve a target than a heavier new age, but I don`t think the gap is as big as sujested. (changing the engine in a classic throws this theory out of the window too)
I had a type R with 313bhp, ran consistent 13.3@105 1/4`s, my newage with 330bhp ran consistant 12.8@107`s. Both ran many times with differing conditions for both cars.

No but also how many people claim power figures without checking my mate came to a Dyno day with me in his 4.4 bmw x5 bmw say she shud 326 and only had 280bhp shocking mine left Japan factory with 260 I've only done decat and induction and got 278.4bhp not bad for 1995 car aiming for around 330 ish heard that's the sweet spot for a classic?
