Real power of the cerbera's?

[brakedust300]

Still looking at getting a cerbera soon and was looking at getting a 4.5 because of the extra power, but some people have said that the 4.2 is nearly the same as the BHP figures are slightly exaggerated!
So what are the real power figures on a standard 4.5 and 4.2?

[FUBAR]

Most 4.2s seem to be in the 355-365bhp area, whilst 4.5s can vary from a poor running un-modded car at 350ish, up to 390bhp is unmodded but a 'goodun'. Most modded/remapped cars are in the 390-420bhp whilst a modded/remapped Red Rose seems to be 420-440bhp

4.2s dont respond to mapping etc in the same way the 4.5s do.

The blue ones have 15 hp on top of that.











And apostrophes just add weight.









Coat, door, gone.

Although this mapped 4.2, whilst not peaking much more seems to have a very very healthy Torque curve thanks to mapping http://s180.photobucket.com/albums/x2

Christ, Ive just seen that torque figure! Im sure my toque figure was higher than this recent one. No idea where its gone.

ETA: Ive just dug out some old RR graphs. My car had 340lb.ft pre map and 375 lb.ft post map (I think I'll discount the graph that started the bunfight that shows 430lb.ft!) so I aint got a scooby where its all gone? Still feels pretty rapid

The yellow ones are less powerful, attract flies in the summer and spend more time in the garage being fixed.
