quote:Mr 8, I love the way you wade in and assume you know more than everyone - very condescending. In actuality, the dyno's we've done all correct for transmission losses, and are therefore power number AT THE FLYWHEEL. My Cerbera with a corrected 398bhp was showing 291 or so at the wheels, i.e. just over 25%. I think these are typical transmission losses.
On another note, many TVR owners are currently moaning that their TVR once on a dyno outputs less power than TVR are stating, the 360 and 420BHP figures are obviosly from flywheel, the 320bhp to 350 seen on rolling roads are from wheels, do you happen to know what transmission losses are once power is through to the wheels quoted by TVR? average manufacturer says about 5% losses, but others loose as much as 10% but still show the flywheel figures which they are entitled to. The 420bhp at flywheel is probably what was shown during developmnent at TVR, but the actual calibration and hardware has probaly been chaged for production since. Any ideas?
I wouldn't say Cerbera owners are typical bean can large bore looks over performance types... so why the having a go here?

As for the HEGO sensor not being able to see any changes from removing the cats since they are before the cats... this is also bollocks. If removing the cats changes the resonance tuning or back pressure, this will change the flow, and therefore change the air fuel ratio which the sensor will measure. Even if it is just a somewhat rough guide. Anyway, like I said, the lambda sensors are ignored 4k rpm plus, so are irrelevant from a power point of view.
Ive had the Joospeed EGO sensor removal!! Simply get de-catted and all previous worries about looking a show-off are instantly gone because now you realise it sounds so good that its your duty to pop and bang to please the world of the TVRless ..........what...........HEGO sensor??..No i havent got a clue what they do!
HEGO sensor is a "heated exhaust gas oxygen" sensor - i.e. what everybody apart from Mr 8 being poncy just calls a lambda sensor. It's heated by a power supply so that it works as soon as possible after the engine starts, since it only works while hot.
When you decat the car, you generally just leave the lambdas in place.

Did you know that Lambda is the classical name for Sparta and that Spartans apart from being the toughest and best soldiers in the ancient world were also gay?
Today the trem 'Lambda' is the adopted motto for gay men?
Just thought I'd throw that in as I'm having something of a history moment......

Whoa guys!
Can we please stop all the techno-bore point scoring?
Bilton; you wanna know the answer to your question?
Well, DO IT!
Remember Clarkson's descrption of the Cerby? "I'm driving the noisiest, fsatest car this side of a Lamborghini Diablo." Sorry, Jeremy but a Cerb with a decatted sports exhaust is the joint ultimate noise in the universe along with most full bore attack notes from various Itallian stallions.
Mine lost a bit of it's original off-the mark sprintability (sod all, really) but was insane at 110+.
It's the ultimate sound on the overrun (as many here have testified) and is why I hope to buy one again in the future. This just should not be a question - please, do it - if not for yourself, then just think of the bystanders. Noise, glorious noise: fabulous.

I drove my decatted cerb behind a DIABLO (D14BLO) yesterday round Godalming area for a few miles - and I reckon he sounded much better (but I am running in and cant go above 3K just yet). I really wanted to give him a speed test as well but again 3K revs aint much use! His car did make mine feel small and not very exciting in comparison.

You lucky chap! Yes, El Diablo is truly one of the great Italian alternatives, acoustically speaking but open your window with the suggested mods (sports/decat) and it's YOU that will be loudest.
Brand new Cerbs are less than enthralling acoustically but wait...and embrace the thunder. You know it makes sense.
I recall parking next to a Diablo at a hotel once and (like a total anorak but who gives a s***t?) sneaking a quick photo for posterity - surprising - despite what you've just said, about how well the Cerb measured up side by side with the beast.
They should make Canonball Run 3 and start off with a Diablo firing along the Arizona desert with a Cerby in pursuit - imagine the sound!
