Danny is the man to fill you in.
It is worth it if you want over 400bhp.
I think it is the only tested way of getting more power from a 4.5.
It is about 4.5K for the conversion.
Best to spend money on suspension and possibly brakes to get a better 'faster' car.
The engine mod is a faster car - but why do you need more speed? If you are a track day merchant with more cash than sense then do it!! Is that right Danny!!!?

Danny,
I know you've probably answered this on another thread but how long was your car at TVR to have the conversion done?
Also re the 95 / 97 ECU mapping, what benefit does that actually give having this dual mapping? My petrol cap says only use 95 but I was told I can also use Optimax (98), how does this work if I don't have an ECU mapping for the different octane fuels??
Do you think it was worth the 4 odd grand to have done if you probably don't get it back on the resell value and does it give you the 400BHP (or thereabouts) figure no matter what your engine was producing before the conversion?
T.

It produces that figure reguardless of the previous power output. Dannys car was already a good'un before it went in, there has been another car that was far lower on torque/bhp and has come out with even higher power and torque than Dannys. Not aloud to say anymore than that I dont think...
IF I owned the Cerb and had the spare cash I think I would go for it. However, your money is probably better spent on decent suspension/brakes/straight cut gearboxes etc etc. Im just a childish little kid who likes big numbers power wise

As dannyit has said in order to get the benefit from a higher octane fuel weather Optimax (98 Octane) or a race fuel like 76 Racing Fuel (110-118 Octane) you need to have the engine tuned/re-mapped. Part of the RR conversion adds a mapping for 98 Octane fuel.
Dumping it in a standard car won't give you the full benefit, despite what Shell may offer on their adverts...

If the car in question has an adaptive ECU then you will get some benefits without other mods. Unfortunately, not TVRs tho.
Yes i think that it can be assumed that if the car has an adaptive ECU then it will be more affective than a car without one. I should have mentioned that earlier
What is the standard ECU then?? It cant be a set map because it can get things incredibly wrong and then correct itself. We have had the car so it is slower than my Smart and quite literally hopped down a dual carriage way. After one slow 0-something run we turned around and did the same again. On the second run the car was nearly right again, the third run had it completely sorted.
If you have ever have the same problem you will notice the difference between it being confused and using the "correct" (still doubt any Cerbera is set up that well) set up.
Anyway, the higher octane stuff has improved our car, but only because it doesn't pink anymore, nothing noticeable performance wise though.
