...that the supposed 420 BHP has been found to be anything from 340-380 BHP on average? Especially those who bought one of these from new.

Or is this just accepted and seen as a challenge to achieve or beat the claimed BHP figures?

A bit but not much. When I go into a dealers, I see them as a special sort of shop. One where the shop assistance is allowed to lie as much as he/she likes with no comeback.

I've been reading PH forums for yonks now and am always amazed how indignant people are when they have a service then something goes wrong with their car. Or buy a 50K porsche only to indignantly take it back the next week because the freebee umbrella won't unfold.

I think dealers are on a hiding to nothing, and unless they lie they can't sell their product in a marketplace where everyone lies.

No... but that's cos I bought a 4.2 and it got me a 365 at SRR, or took at it another way, up on factory figures

I think the 4.5 AJP was a 420hp unit when delivered by Al Melling, but then TVR made a bit of a mess of the other stuff, induction pipes and mapping for example. Its a great engine, just needs a bit of help to get it back to its intended spec.

Nope cos my 4.2 was spot on

Interestingly, I've now twice tried my car in acceleration against a 4.5 (up to third gear only) and there's nothing in it. In fact my 4.2 seems to get away quicker initially and then the two seem equal, but I've got my nose in front.

Did the factory make the 3.9 sec 0-60 claim because it was a bigger more powerful engine and had to be seen to be quicker than a 4.2 for marketing reasons?

Its because the 4.5 is probably putting out the same power as yours!

The 4.2 has lovely controlled acceleration in a "free revving motorbike" sty-lee.

The 4.5, seems to give you a big lump of torque when you don't want it. I've know doubt I'll get used to it, by learning to feather the throttle in the right places or getting it mapped.

Until the 4.5's been mapped / visited one of the tuners, I'd give the edge to the 4.2.

must've got this from caculations on a zx81. Didn't a magazine (autocar?) abuse a 4.2 and a 4.5? To be fair to TVR I doubt there is a car manufacturer in the world that does not over exagerrate performance

i think that anyone who spent over 50k on a cerbera..only to have it slowly fall to bits at serious ing cost ..or to then have an engine rebuild at more serious cost... or for it to burst into flames at more cost..or to buy a car that they tell u is 420bhp but only chucks out 340...and to fic it is more serious cost...i think that in reality this is worse than the nigerian scammers...its a ing joke...

if it was a skoda we would accept such bullshit but a british cerbera what a joke...i only appreciate my cerb cos i paid decent money for it but..had i paid 50k for it i owuld be looking for the dealers head.

Ahem... the press 4.2 has 359bhp (which did its own figures for Autocar, who found it suspiciously quick and dyno'd it themselves at said number), 4.2 to 60/9 to 100? Unless unhealthy all cerbs are around that mark. In terms of performance, they're quite simply astonishing even as standard - regularily punching above thier weight at sprints/hillclimbs/speedtrials/vmax's - you'd feel short changed? how?

A few LIGHT mods gets them to around 400bhp, which with just 1200kilos to push about is plenty... I've been in some f'kin fast cars and not much will stay in touch with a Cerb to 150, honestly! Infact, if you look at Cyclones 1/4 times, they equate to quicker performance than claimed originally for the 4.5... and that was with 410bhp/ it was repeatable!!

Bagua, how would you feel if you paid £100k for a Ferrari and it didnt make the numbers? paperbag

I think its rather akin to the garelli moped I used to have. The carb went off tune before the bike was sold to the public. It had poo poor electrics which were colour coded black from top to bottom. The starter was a set of pedals that broke the first time they were used to start the bike, and pretty much every journey you lost some sort of fixing which rattled off the bike.

But if tuned before every journey, and 10mins bump starting, its collosal 12BHP could propel you past your mates FSIE's on the journey home from school.

For some reason you could forgive the bike everything after that.

You will only feel cheated if you didn't do enough research on Cerbera's. The 4.5 bhp and performance figures are all taken from the original road tests on the car supplied by TVR.

The 4.2's and 4.5's give out very similar power figures in standard form, that is pretty common knowledge to any who knows Cerb's. So if you bought a 4.5 simply because you believed those original figures, then you have made a mistake.

In standard form they should be viewed as very similar cars in terms of speed, but different in terms of character. The 4.5 is torquier,with a slower revving engine, and it feels like a "heavier" car. The 4.2 is a quick revving more responsive engine, and so feels quicker.

The advantage of the 4.5 is that if you wish to spend £1000, you can get increase the hp up to the 400'ish mark.

I also believe that as far as used cerbera values go, any 4.5 Cerb that has had the short induction kit, and a re-map, should be priced higher than a a normal 4.5 to reflect this fact.

The thing is - I've always wanted a Cerbera since I saw them launched, so partially figures/speed etc doesn't matter. Surely having a TVR is much more than just figures, if so people would be buying Rice Burners with huge turbo's/mappings etc and pushing 500bhp plus, however I know which one I'd rather be driving.

It's the whole package surely, the styling, the lightness, the acceleration, the noise, oh God the noise and the other owners.

Having said all that - speed is like an addiction with me, hence why I've ridden motorbikes since I was 16 and still use one to commute everyday. It's finally nice to have a car with bike style performance.

I'm happy. I bought mine with all the power it should have had at its birth.

Well, I have gone into Cerb ownership with my eyes opened to the power facts, thanks to this forum.

This hasn't put me off, and I am happy to say that I should have mine in the next couple of weeks

i agree with byker its the whole package imo that counts i dont really bother with the figures i know i get a buzz out of driving the cerb that i have not had from any other cars i have driven, all i know is that my 4.2 leaves most cars for dead whatever the figures are, so if it aint broken dont fix it
