Difference between standard 4.5 and red rose

[tvrtuscans]

Greetings all, Can someone enlighten me as to the difference between a factory standard 4.5 Cerbera and a factory red rose car. Ta in advance.

Owners of RRs have bigger testicles and deeper pockets

Sadly I have neither of those attributes.

A button.

skimmed heads, a flap wheel down the ports, an ecu chip and a button that sometimes doesn't work. that'll be 2350 plus vat please. easiest way for tvr to make 2k ever!

The Red Rose was I guess the pinnacle of the Cerbera range. Based on the 4.5, but tweaked, reaching for motoring perfection. The engine was tuned, and you had the option to hit a switch on the dash, which would tell the ECU to change to an alternative fuel map and you'd get the benefit of 440 horses pulling you along. The Red Rose was also giving larger brakes and tweaked suspension making it a very formidable package.

Wow J
That's 117.5 pounds per bhp over a std 4.5 claimed figures.

When equated to a std 420bhp it costs 49350 pounds, another usless fact!

3 angle valve seats, increased compression ratio, button for which fuel you're using. Anything else on engine?

[jackwibble]

Blown head gaskets due to raised compression??

though to be fair, a std car is about 350hp and a RR is about 410hp so the gain is actually pretty substantial in reality

Cheers mate, about time my balls got recognised but my arms are short.

My late 2001 4.5 LW RR Factory Build Sheet says :

Raised Compression ratio (no figures stated)
3 angle valve seats
Re-worked and polished ports
Balanced combustion chambers
Optimised cam timing
Re-shimmed cam followers
Upgraded head gaskets
ECU EPROM chips (?)
ECU 95/97 octane switch

(not sure what items like 'optimised cam timing' actually mean; just
copying the paperwork)

This cost an extra £3290 on top of the new car price.

Ok then 39 pounds pet bhp in the real world!
First time reality is cheaper than fiction!

Thank you very much playmates for all the info

An out of the box RR is 410bhp Joolz??

I only ever saw a couple on a rolling road and neither broke 370bhp.

Mine was 406 at Charlie's with nothing at all done to it. Ok Jules did set the throttles up, but no mods, even had the cats in.
When are you going to get another Cerb cyclone?

[spitfire4v8]

Yes the worst factory RR i ever saw was 398hp I think, most are in the 405-410hp range. There have been a few rebuilt red roses that don't make the power though, one was 370hp I remember.

[greenracing]

My RR was on the dyno last year at a local Tvr meet and made 398, that was with a burnt out cat on one bank, a diff that was shot and cam timing that was not as accurate as it could have been. I was still disappointed but after reading a few posts on bhp figures and surmising that if the cat was ok, the cam timing sorted and the diff recond ( all of which have now been sorted) that it old have broke the 400 mark. For a few more bhp I could remove the cats, put on the short induction and I think it would see north of 430 from what I can see the decay and short induction gains normally are.

The car is now in a container on its way to oz, hopefully I will see it in 6 weeks and he real fun will begin trying to get an import plate!

Joolz, Nick,

Cheers for the info, my memory is definitely fading. I thought there was a RR at the original Surrey Rolling Road Shootout.....way back in 2005/6? This is the one I thought made 370ish, anyway what you say makes sense, of course Nick's made good original numbers and was a good target to aim at for catching up with the early modifications.

I'd love to get back in a Cerb, when my Sons are old enough to get involved, then a Cerb project or similar will be on the cards. Too much time invested and knowledge gained to not be put to good use. I am currently enjoying my Merc and it should be the first car I have had since the Cerb, that can outstrip it on the 1/4 mile....we'll see.

Jules.

My rr made 415 at SRR.
100% Standard.
(Except for the yellow pack tesco petrol)

[Mr Cerbera]

What speed did you get out of her on the Kemmel straight Aide ?
The best I've ever done is 145 - and she was rated as 362bhp then.
