The Laughing Cerbera
NOS for your 4.5 Cerbie? An extra 140bhp on tap...
TVR Power have a number of power upgrades available currently but their most outrageous kit is their new 'Laughing Cerbera' Nitrous Oxide system.
They've fitted the kit to a Cerbera that's already had a Red Rose upgrade. Featuring a progressive delivery system, the kit is claimed to provide an additional 140bhp!

For how long? Well somebody had to ask it.
the kit is limited to 140bhp so the engine can handle it. The set up they have based it on is craig's car www.pistonheads.com/members/showProfile.asp?memberId=26500
It will produce 300 bhp if you wanted to break things so its set at a lower level, unless you want to programme it to destroy aboslutely every other car on the road....and the engine

580bhp 
Curiously the power claim on the TVR Power site says 460bhp. Or are they claiming that's the base power before NOS?
surely not? I thought its around 350bhp for the 4.2 and 4.5 around 380. No idea where that figure has come from
AFAIK Craigs car is running around 550 with Nos but to get the 4.5 to Red rose 400bhp spec required quite a few little modifications
I thought the "official" Red Rose output for the 4.5 v8 was ~450bhp...
To only have 460bhp with 140bhp of that from the NOS would mean a stock Red Rose 4.5 has 320bhp, which I'm quite sure is wrong.
Either way, TVR ran their Red Rose 4.5 upto 150mph in 17.1 seconds (I think thats the time anyway), so to achieve that kind of number you do need 420bhp+
I've heard rumours that the Red Rose used there was 450bhp, but that the one people get is more like 415bhp, and the stock 4.5 is like 380bhp!?
Tell me if I'm wrong there.
Either way, adding enough tanks of NOS to make it viable (those 140bhp jets on 8 cylinders will dring NOS), then you'll add weight and complexity.
Surely removing weight is the best way to go with a Red Rose, hence TVR's own lightweight pack!? For the money it seems ok, but again, how much is it going to cost you to run with a progressive system on all the time?

dont quote me Mr Whippy. I really know very little about cerberas so not the right person to comment really. Just confused when Ted posted that quoted figure.
Why would it be expensive to run? The car is fitted with a remote bottle opener. When you want Nos, switch open the bottle, switch it on, plant your foot, and bingo. Switch off nos supply and its a standard cerb mpg
Whippy, The ex-press car has been sold to a PH'er/ a PH'ers friend who said that it doesnt feel that much different in a straight line than his previous Cerb(s?). However the handling was said to be far better!? something that TopGear mag slated the Cerb on saying the lap time was "disappointing considering its straight line speed."
A full TVR Red Rose pack for the 4.5 brings the car to 400bhp+, as with all things TVR, this figure varies a little, but Danny LT who had the first *conversion* had his on the dyno @ 399bhp. Since then there have been cars at 428bhp/437bhp, of course whats probably more important than this bhp talk, is in fact the torque - which seems to be up EVERYWHERE on all the factories Red Rose cars.
From the looks of the TVRpower website all that is fitted is a "Red Rose chip"?? whatever that is? Either way, the 460bhp claim seems to imply that Craigs car had 320bhp to begin with!? I believe he has already said before hand that his car started with 380bhp, so I think this may just be an error on TVR Powers part.
FWIW I have never seen TVR's own "Lightweights" weighed at less than 1200kilos, whereas the good old pre-LW's seem to have come closer to 1150 IIRC (Davidds car?) Which is bang on considering the 1100 figure TVR give is for *dry* weight.
A full TVR Red Rose upgrade is still the most proven way of producing 400bhp+, however Craigs set up seems to absolutely eat RR cars power figures. It will be interesting to see what it gets on a Rolling Road, truly does seem to be a fantastic project and car.

If you all read TVR powers post correctly they're assuming on average that the cerb puts out 355bhp or there abouts. Some have more (like mine
) some are less!
Add a NOS kit designed for a maximum of 140bhp and limit it to around 75% and there you have around 460bhp. OR turn it right up and add a few other mods and your running over 500bhp.
As for BCAs comment regarding my car only having 320bhp well even with out the NOS I can leave most things for dust even a Red Rose tuscan! So I know for a fact that its closer to 400bhp. You can imagine what happens with the NOS on!
And for the record I've awaiting some more goodies. They should be arriving very shortly and I'm aiming for 600+ or burst
which ever happens!
some piccies of whats done so far:

Not my comment, just said thats what TVR power implied...
A decent Cerb should take a Tuscan RR, have seen it plenty of times before. I have a feeling that your little run against a Tuscan RR showed more of a difference than is usually obvious
Im intrigued as to how the Cerb handles the power though?? Our car, (producing less than your 380bhp) seems to struggle for traction in first and second on hillclimbs in the dry, in a straight line. Occaisionally causing a few scary third gear slips too...
What tyres are you running to handle that kind of power, or do you just have to be even more progressive with the throttle??
Really does sound immense, shame it wasnt all in place at VW/ hadnt got a clue about your plans at that point

Some of it was in place at VW but I still had to retrim everything before it looked the part so not too many people saw it.
The tyres are Toyos 245s I didn't have much luck getting grip 1st or 2nd when it was all standard but its much better now I've changed the suspension for AVOs

Oi leave it.
What I never said it was YOURS!
it may have been someone else....... You still want to buy this car back??? first offer of around £1,000,000 will secure.
