TVR S6 v The rest
Discussion
With all the development work carried out by various engine builders and TVR Power now offering a 5 year unlimited mileage warranty, would it be fair to say (assuming the claims are proved correct) that the rebuilt S6 is the most reliable and powerful - bhp/ n.a litre straight 6 road car engine.

If we could see some engine dyno results from an independant test house, then maybe we could. However, I would have a long hard look at some of the power coming from 4 cylinder car engines in road cars.I would guess the S6 is probably a wee bit short and would need to see the otherside of 500 bhp in its 4.5 form to realise that accolade.
Is it reliable? far too soon to tell. Because a 5 year warranty is on offer doesn't make something reliable, it just suggests that the man behind some of the builds has faith in his product.
Positive - there are certainly less critics of the engine now.
The well rebuilt engines certainly seem to be bang on 100 bhp/litre. I know my 4.0 Tuscan S is as I've run it on several different dynos and it consistently does 350-360 bhp at the wheels which is 400 at the fly.
Whether you could class a rebuilt S6 as a production engine is a different matter.

Rolling roads (granted) but I've had three different ones on mine, all posted on here, yet people keep nibbling away. I suppose if/when a negative report appears that'll be seized upon as The Proof some want. In the meantime I'm more than happy that Power have done what they said they could and are standing by their work.
As a customer that's good enough for me.

I agree, happy customers are what is important.As a customer that's good enough for me.
The OP was around high output relative to other N/A engines. To compare first you need a bench mark and a rolling road is not it. I would like to see some real comparible figures just for curiosity - not to knock.

Completely agree. I don't get the need to cast doubt, they deliver ( 4.3 owner)As a customer that's good enough for me.

If you are happy then I'm pleased for you also.
Should know better to get involved with fan club members...

Can you post the results and say what the dynos were please, I'd like to hear some numbers, I don't remember any on here before. Surrey rolling road would be nice so I can compare to mine!As a customer that's good enough for me.

And to put the cat amongst the pigeons an engine on a bench connected to a dyno is only going to answer questions like this one
, if you then put the same engine in 2 cars of equal weight but one is 4 wheel drive with an auto box and the other is a rear drive manual the losses at the wheels will be hugely different, so an at the driven wheel figure is going to be more representative of the cars performance... s6boy said:

I didn't even notice the ref to 6 cyliner engines in your original post. So, after reading all the words in the order they were written - which requires very little clarification...a revised answer to part of your question.
Yes...I think the rebuilt S6 engines from the bettter builders may well be the highest output 6 clinder engines per cc
