Interesting Supercharged Cerb...
Discussion
Here's link to that Cerbera, so you don't have to go searching.

I quite like the Ali air boxes,
Not so keen on the cloth seats (or are they suede?) and the nasty wheels!

reading the add again ... sounds like it was grief to install .. doesnt mention engine upgrades to take additional power? ... this versus NoS??
Im sure the birth of the Pheonix will generate enough interest for an "off the shelf" but not 1000BHP supercharger???
....
I wondered what an alcantera interior would look like ... now I know I wont do it! (maybe roof lining though)
Wheels dont do it much justice ... original white the car was may have looked better MrMops white cerb looked fantastic when I saw it at Offords!
As I say interesting though! ... DAS

Its a simple blower setup with no engine mods, you're better off with NOS, which will yeild better results. But I cant see it lasting long if the engine is still a stock 4.2.
And the use of the existing throttlebodies and the huge pipework that has been setup the way it has, this is a poorly designed setup, a single blower with low boost will not work efficiently.
There have been 7 supercharged Cerbera conversions in the past, of which 4 went to TVR heaven. The 3 remaining do not include this one, so its a new one on me too. But as far as I know, they all remained stock with just a few modifications to get the blower in.
Dont worry chaps, we brits do it best, the 1000RWHP 6 litre will be our mark....

.....power or no power, that IMHO is one of the most horrible Cerb's I have seen! david smith said:
I new it would get your interest SXS ...
I didnt realise there had been any conversions already ... not on your scale!!
I think your guys would do well working a more "designed" set up with engine beefed to suit ..

Damn right old boy!
Wait till you see the engine bay designs that I had designed... its only 2 months left.... but lets just say, I am doing my utmost to keep the TVR Cerbera timeless s-e-x appeal under the hood as well as in the cabin....
I know the TVR critics out there all to well, but thankfully my thoughts are also on similar wavelengths... (I'm not a firm believer of 'pipes' all over the place for all to see, I like the neat, controlled, tucked away, easy to maintain but 'looks mysterious, whats going on under there' approach....)

Hey sxs, talking of nos. What does your engineers thing of the engine in standard form? Just thinking of what a safe power level would be if fitting nos on a standard engine.
If I told you what they think of the engine in standard form, I will probably get flamed by every cerbera nut here... (but then thier views are based on their 20 odd years on working with race engines etc)
with progressive NOS, you can easily get up to 450break. Anymore than that and you're running on 'borrowed time'
Detonation is a killer, but NOS does have a cooling effect which will help.
With progressive NOS, the extra power comes in smoothly as the car pushes through the rev range, so the extra duty put on your engine and drivetrain will also be progressive and its a good comprise, but rest-assured, once you're in the 60mph odd zone, you will think you're going twice as fast... the extra 150 horses are REALLY noticeable...
If you're interested in a quote, drop me an email.
I believe the best power adder without going forced induction, is getting the engine rebuilt to a 5 litre spec and increased compression. But for this to work properly, you're looking at bills of around 6k. But hey, you get a rebuild and increased torque/power cheaper than a TVR rebuild... so take your pick...
But NOS is the cheapest way, only problem is the extra time spent going to the nearest refilling station and getting your bottle refilled, some will use NOS sparingly, but most get used to it and will be dumping it every chance they get. Plus NOS will not work wanders with your insurance quote.
Go for the rebuild, 6k aint bad, and you get a new 5-5.5litre engine back. That in itself increases the value of your car if you decided to upgrade to another TVR or something...

Well thats it, if you need a rebuild why go for a 4.5 max from tvr when larger cc's are available.
I take it that a 5litre odd conversion would be less stressful on the block than the full 6litre your going for?
The 6 litre requires EXTENSIVE mods, because the max that can fit within tolerance is 5.5! Plus you're talking double the costs of the rebuild, and it will run like a dog due to the LOOOOONG stroke unless you compensate it with MASSIVE forced induction....
5 litre is a perfect compromise, less stress on the engine due to a longer stroke = less pressure against cylinder walls... plus mate it with increased compression ratio and you will have a VERY powerful NA motor!
With this rebuild, you are looking at well over 150bhp extra, depending on how extreme you want the compression ratio... but remember, more horses = more costs. Regardless if its via the NA route or forced induction route.
But saying that, there is a limit to how high you can go on CR alone, due to the octane rating of unleaded fuel and also you have to get her through emmissions... But from my understanding, an 11.5:1 with a 5 litre crank setup, and some interesting (classified) head work.... you can push her to power levels which TVR could only dream of... if only they dug deeper into their pockets and got MCD to develop the AJPV8 further... sods! Also, the engineers can get rid of all the problem areas in the engine and make the engine as solid as a ricer engine.... proper nikasil liners, berillium bronze or bronze copper valve guides, nitrate hardened valve seats.... roller bearings on the cams.... teflon coating the buckets... extra oilways to lubricate things better... and an enhanced way of lubricating the setup from the wetsump setup or go all the way and go dry sump for a TOUGH as ROCK setup...

SXS what you say mads sooo much sense ...
I would like to be using my car as an almost daily ride ... without the fear of the engine going pop.
Its a god job my heart rules my cars or I would never have gone down the cerbera route!
Mine is an older engine 53k miles on a 98 plate and I have no intention of rebuilding until needed
BUT
when I do it wont be with TVR ...
I like your approach a rebuild should always be an upgrade ... power or reliablity preferably both!
I have just booked in to the cerb rolling road day ... will be interesting day Im sure .. Are you coming along? will you need a lift? ... DAS
