Everybody goes on about bhp figures of ther scoobys but not how the weight of their cars affects their performance.I found out how weight was such a big factor several months ago before I sold myUK turbo 2000 wagon ,a friend had a 2003 wrx sti with full decat,remap and all the extras, my wagon had full decat,no remap.From 20 mph too well into three figures there was basically nothing in it much to my surprise and my friends dissapointment.
Obviously this was on a private piece of dual carriage way and I do not encourage breaking the speed limit.
When my mate was at the scooby specialist the following week for some more exspensive mods he mentioned the similar straight line speeds and was told that my car weighs 1235 kg and his weighs 1470 kg.This equates to him having three 12 stone passengers and my weight advantage takes an awful lot of bhp too overcome.
So basically what I am trying to say is bhp figures are not everything.

 

Bhp per tonne is everything.

Not sure that a uk wagon weighs 1235kg though.

 

Agree totally with the OP - POWER TO WEIGHT ratio is what matters, not just BHP - I'm sure big lorries have huge bhp figures, but I wouldnt want to race a car in them.

 

I have old 99 2000 uk turbo brochue and says in the back 1235kg for saloon .I have 05jdm sti and that 1460kg .Regards lorrys have 580 bhp or 610 it the torque they produce.The jdm sti i have now to me gets up to speed a hell of a lot quicker than my my2000 uk turbo i had and that had h&s turbo back system panel filter tek3 remap by Andy f

 

You'll get your ***** whipped all day everyday by LocoCaterFields with 120-170bhp bike engines, mainly because they weigh no more than 400-500kgs.

A hayabuse engined Locost could have 425bhp/ton!
