Red Rose 4.5s

[Tripps]

Does anyone have the details to hand of what the actual differences are between a standard 4.5 LW and one with the RR kit?

Cheers

a little button to change maps between 95/98 - "Red Rose" scribbled in marker on the ECU - less tyre tread at the back - 50bhp+ more than a normal 4.5 (a guesstimate, sometimes more than that, like up to 90bhp more)

Lowest RR that I know of: 399bhp / reasonably big torque

Highest RR that I know of: 438bhp / big torque
both figures without further mods.

Given the choice of two cars, same spec, except one was the red rose - and say £3k more expensive - I would pick the red rose and eat beans for a while. The Cerbs the daddy of TVR's, the 4.5RR is the daddy of the Cerbs.

Does that mean it can run fine on 95 then for trips abroad etc. I presume it would be down on power, but even for if you can't find 98 octane...

I dont know about daddy of cerbs, they're all within .1 of a second within each other (4.5's) but I understand the RR gets up to 160 and over a lot quicker....

Well as long as it feels faster than the 4.5s I've driven I'll be happy

Well their handling is better, their response is quicker.... but I suppose most standard 4.5 owners have already gone to nitrons and also some beefed up tuning to smooth out the flat spots...

Anyway, I guess anyone can always stick the RR sticker on the back if they want...

[quote=SXS ]Well their handling is better[/quote]What sort of changes did they have to improve the handling then?

Was it just Nitrons as you mentioned?

[SXS]

They dont use Nitrons as far as I know (unless they had started recently?), Nitrons are comparable to the likes of Ohlins but at half the price, so unless they're also using mono-tube racing shocks I doubt the RR setup can touch the Nitrons - a different class... joo is a lot more clued up on this than me.

Higher compression, ported heads, different injectors, waisted exhaust valves, different ECU mapping. And double valve springs I think - I had the list somewhere. Anyway, it ran like crap on 95 the one time I was forced to. The RR engine runs nicer than the standard 4.5.

Completely pointless power increase of course... but then you can't have enough power either

Nitrons make a far greater value-for-money difference.

Methinks they'll have to wait though, need to get this Cerbera first
