TVR Power 5.0 litre
Discussion
I would love to have one of Powers 5.0L speed six engines in my Cerbera it will be an awsome engine but I can't afford it I'm afraid, good luck to the 10 that can you will have one hell of a car once installed.
Also good to see power continuing to develop there own engine at there own cost. Unlike other garages I could mention that use customers engines at the customers cost to develop there product ideas sometimes with disastrous consequences for the customer in time and money.
Well done Dom.

Will the gearbox etc have to be upgraded to handle that torque/power?

Its a massive jump in performance from standard.
Not really. A standard Sagaris is 380HP from 4 ltrs, i.e. 95BHP/ Ltr (don't know where you got 330BHP from). The 5ltr is 405BHP from 5 ltrs, i.e. 81BHP/ Ltr. There are a lot of engines out there that do 100BHP/ Ltr so truthfully, based on that table you've quoted, its not that great.Standard Sag

And 405 BHP isn't much to be fair. Crate chevy's start at 420 BHP. My chevy truck had 600 BHP. You can buy a mustang from Ford with 662BHP straight from the showroom.
All power to those wanting a 5ltr S6 in their TVR, its a good engine (once up to temp) and make a great noise. But its not 'all that'.

Look again at what I have posted, I have only gone to 6k, its low down torque that breaks stuff, the 4.5 ss that was in the racing Sag destroyed gearboxes and it didn't have the torque of a 5 litre, across the rev range and up to 6k it produces around 100 lb ft more than a standard Sag.And 405 BHP isn't much to be fair.

That's quite a drop in bhp/L!WolfyJones said:

Fair enough but its still nothing spectacular from a 5ltr engine.fatbutt said:

Fatbutt come to Tvr Power and ill take you out in the 5ltr then tell me she's not spectacular, as for the 4.5 ss breaking gearboxes thats simply down to the development box being shyte

Hi Dom - not wanting to sound insulting of your work, just wanting the fanboi style comments to be a bit more realistic in their appraisal of the figures. I'm sure whatever you have the 5tlr in will go like stink but put it in something heavier then it simply wont. 100BHP/ ltr is pretty much typical for BMW N/A engines isn't it? I'm sure you've worked wonders with the TVR S6 but the engine in isolation, i.e. not in a Tuscan or other 1.1Te car, is not a new specification benchmark.Dom
As for the box, I'm staying out of that discussion. The Tremec 6060 I have in my rod seems pretty happy with 420Hp...

Bloody hell, let the lad finish development before you start having a pop, up to 6k it looks a stonking engine and I,m sure more will come, thou even now its got far more punch than the factory units.As for the box, I'm staying out of that discussion.

Try not publishing figures onto a public forum that show the engine isn't quite as powerful as other units in the same field then big up the numbers like they are somehow extraordinary. Excessive praise, as you dish out on numerous threads about Dom's work, leads to greater scrutiny and criticism. Like I said, I'm sure TVR Power have done a great job but FFS, tone down the butt kissing for Dom's sake, you come off sounding like a star struck 13 year old.

Lol, very good.Excessive praise, as you dish out on numerous threads about Dom's work, leads to greater scrutiny and criticism. Like I said, I'm sure TVR Power have done a great job but FFS, tone down the butt kissing for Dom's sake, you come off sounding like a star struck 13 year old.
Figures were already published,
Figures are extremely good lower down the rev range where most owners think the S6 is lacking,
What Dom and Winstanley did with the 4.5ss was bloody amazing,
Now if you don't like that bugger off and get back in your hole, smile
