Greetings all,
I'm just trying to find out what is a ball park figure for the bhp of the AJP 4.5, as a mate of mine just purchased one, and is a little disappointed with the performance, which shocked me, as being a TVR fan, I have always thought of the Cerb as the fastest and most brutal accelerating tvr.
He's looked through the history and can't see any engine tuning. It has a sports exhaust, but I think thats it.
If you could give me any information, it would be very helpful.
Thanks in advance

You joke but when following him in hot pursuit in an e92 M3, we saw his brake lights come on! An electrical gremlin I assume!
Although the accelerator pedal is quite stiff, with a long travel, it has crossed my mind that he's not always foot flat down..
You do know its illegal to drive using binoculars !!! Although the accelerator pedal is quite stiff, with a long travel, it has crossed my mind that he's not always foot flat down..
It's not my M3, but no he can't really beat the beemer at any speed, they are very closely matched.
But even the owner of the M3 was surprised and wouldn't have minded coming second fiddle, as he's owned a Griff before and loves tvr's.
I assume it's barely making 350bhp really.
He's going to get it on a rr, but I just didn't know what figure to expect, and what are the most common mods to get the engine back to full health?

That's just what he'll want to know, thanks chaps.
It's not slow, to be fair, the M3 is a very fast car, and never lets up. But we all expected the Cerb to be slightly faster.
So then you naturally start to doubt the stats by TVR. I assume it's a fair bit heavier than quoted and not close to 420bhp
The Cerb is awesome though, sounds fantastic, so angry in it's delivery, and loves to pop and bang on the overrun.

Mine was quite slow when I first got it. After a year or two of putting up with it, it went to kits & classics where it was found it only produced 240bhp.
Diagnosis was fuel injectors and blocked cats.
It's now at 340bhp which for a 4.2 with a high mileage engine and no rebuilds (that I know of), isn't that bad in my opinion. Obviously, we all want more but for what I use mine for - it's sufficient.

Really great information, thank you all.
He's based down in Devon, but we're used to having to travel to get anything decent
We have just got back from a trip to Le Mans, I'll try to post a photo of her.
It didn't like the scorching temps though, struggling to start and select gears.

Has he still got the cats in?
This heats up the clutch and gearbox. First step would possibly be to flush through the oil as if it's old it can get difficult when hot.
Part of the reason I flushed mine and removed the cats.
As for power - any number of reasons - first thing would be to stick it on a rolling road - see exactly what it's got.

Have a look for a post from Aide where he got a shim to put in place between his starter motor and the engine casing which helped solve his hot start problemsActually.. here's the link - that makes life easy

It may well be that there was an amount of deferred maintenance since it's only recently been purchased. Therefore it will probably need a 12k service which includes the valve clearances. Also blocked CATs contributed to the poor performance of my car when I bought it.
As others have said, a trip to Joolz will transform a 4.5, but do not underestimate the stress that the rolling road will put on the car. Make sure the car is near perfect mechanically first. Mine simply cracked a manifold, but thankfully immediately after the remap was complete.
