Racing Green - buckets anyone?

[Far Eastender]

TVR Power are stating 370HP at the wheels for the 4.3. What's the output of the Racing Green engine?

[Dicky]

pretty sure it was around 400 bhp

Oh ye of little faith, John.

So I take it you don't want to wager then.

Faith, optimism and cynicism are all attributes you should have in equal measures when dealing with engine builders. Some (not all) builders also require very deep pockets as an essential attribute....

[supercopa]

max output is no incidence for me, everything is on how the power is delivered all along the rpm scale
with the FFF engine, the power is delivered smoothly and continuously from 1500 to 7500 rpm with a max around 390hp at the crank (not at the wheels), with a 3 years warranty and servicing intervals every 12000 miles, that's perfect for a foreigner who has no one able to take care of the engine near him.

Would be interesting to compare dyno graphs from Standard S6, FFF and 4.3L.

392bhp with the lower 10:1 compression ratio...

[Don1]

At the wheels, or crank? And thank you HPRulz, very interesting...

[supercopa]

at the crank as I told before

how many miles has the current development FFF engine done?

As the FFF still has shims that require adjustments, I guess actual time/miles between shim adjustments will only show up in due course ie will it make it to 12000 miles before it needs an adjustment or not.

I certainly hope it does!

I thought it was 397 at the crank, but probably I'm wrong and anyway 5hp is moot.

However, as has been said that is with the lower compression engine. Also, the new heads and further improvements over the engine in the demo car are expected to increase the power somewhat. But as has been said, it's more about the longevity and technical superiority than extra power. There's always the SC for that, isn't there Pascal?

Went to power today to meet Dom have to say very impressed and the 4.3 certainly has my attention especially with the 5 year warrenty.

Lee you Tam is an 06 is your engine knackered or do you just want a new engine?

Sort of knackered.

One of the exhaust valves is buggered and another one on the way out. I could have had a minor rebuild, but decided to go the whole hog as I intend to keep the car.

Not sure about the precise technology as I'm a numpty, but yeah there are some shims. But RG expect to both extend the service periods and expect to only have to do any shim work at about 20k I think.

What would life be without one? LOOOOL

All systems are go.

My Tam will be going in to RG next week for strip down.

Bottom half of the engine will be sorted next week, the finished heads will be available early the following week.

So 28th February looks to be the date.

Would you like to place a wager it wil be mid March earliest??

So...... How many beer vouchers would you like to wager John?

Have just been re-reading this thread over again and what stands out the most to me is a re-build costing £9k + that on the face of it gives genuine "S" spec performance and probably a little bit more lower down the rev range. Am I alone in thinking that, even if the bucket design proves to be hugely reliable, that's a lot of bucks for not a huge amount of extra bang. Power's 4.3 rebuild is giving approx 450 bhp at the crank and a bigger slug of torque throughout the rev range. Chuck in the 5 year warranty and all this for roughly the same money as RG's solution. Surely Power's offering is a bit of a no-brainer by comparison ?. With a 5 year warranty who cares if their 4.3 is not as reliable as RG's bucket head design ?.

[warpig]

surely combining the two would be the ideal solution?

I do... And I have my genuine reasons to do so.

My thoughts exactly

[sidewayz]

I have opted for the TVR Power rebuild. My reasons are I trust Dom and his team because I have heard good things about them and, if you talk to them, they have also done their research and have had input from people who really do know the engine inside out,all the variants of it including the typhon,T440 and V12 versions and all head options (excluding RG's as far as I am aware)

However,I also think it is great that Racing Green have done the work they have and can offer a different solution.Add in Jason Clegg and we now have three good options to stretch the reliablility and performance of the Speed 6 to AJP8 baiting levels.

Anyone who can remember the bad days of the Complete Wallop talk and the disaster that followed that will recognise this is a great time to own one of these iconic engines.

I thought someone said the racing green engine is based on the mods performed by TVR on the Speed 12 where the finger followers were changed for buckets? If that's the case, you'd imagine Dom would have seem it?

edited to remote the quote.

No idea. Just to be clear on this point,it was confirmed to me by one of Dom's team that they had input from someone from TVR who was involved in the development of the Six in its various models including the V12 development.There is no link of any kind between the Racing Green design or the Power design that I am aware of

Thanks DeeJay 22:58

You've obviuosly been to see them today and are full of renewed confidence that they will deliver on time.

One beer and a good chat about how the engine meets your expectations would be fine.

PS - spoke to my engine builder about my motor on Friday - I was due to collect it next week but the heads are showing unedxpected signs of valve seat recession and the build completion maybe delayed while hardened seats are fitted..I will find out on mid week if it will be finished on time!
