how much power difference is there between the 4l and 5l

Enough

[funbobby]

mmm i know what you mean

Nice to see you again kid and actually have a bit of time to show you around the old gal, mmmmm! Can you remember when i offered you my car about 2 years ago hindsight is a wonderfull thing if we had it, any way i have to say your 4ltr goes bl**dy well compared to the couple i have been in so stick with it and forget about the rattles and just enjoy the thing By the way it would look better with my wheels and headlights but DO NOT SPEND ANY MORE ON IT!

A 4L up against a 5L will not put the difference to bed unfortunately! Way too much variation in the power outputs of both and the car weights.

A simplified example:
A standard 4L with 210 bhp and 1050 kg gives 200 bhp/ton
A standard 5L with 250 bhp and 1125 kg gives 222 bhp/ton

Proberbly not a lot of difference in performance

A standard 4L with 185 bhp and 1125kg gives 164 bhp/ton
A standard 5L with 275 bhp and 1050kg gives 263 bhp/ton

BIG DIFFERENCE!!!

Dont think the above examples are unrealistic either. Please correct me if i'm wrong.

My pleasure

Jons' point is extremely salient about the range of performance you can expect from the models. There may well be more 500s over 300bhp (doesn't seem unusual these days!) than 400's with 220bhp which skews the results even more. With the best will in the world you never know what is a definitive car within the marque, try 6 500's and they will all feel quite different?

sorry to sound daft but how does a standard chim come in a different weights bar the fat bugger behind the wheel maybe?

Much more fg in the front end and all the lardy arserp twirly stuff in the newer models

Is the Nitrous system covered/insured for road use too?

No the bottle has to be fitted and plumbed in at the dragstrip.
Only takes 10 minutes tho.

Isn't that a bit unrealistic???

If you're talking at the flywheel a 185 bhp 4L Chim would be about the worst I've heard of...and if your talking about at the wheels a 275 bhp 5L Chim would most certainly not be standard.

I thought they were pretty realistic extremes, I would hazard a guess that there are more cars (than we would like too low!) outside that range

[Hoover.]

from what I've seen on rolling roads... Jon's figures I would say a fair average of the majority of the cars out there.... most cars are +/- 10bhp of those figures
