You guys have some patience!!
The 4.5 from power is up and running, race proven and comes with a warranty and achieves roughly the same BHP as you are hopefully getting with RG and it would have been on your drive months ago. Hope it all come good in the end and is worth the wait.
If I'd wanted to just bore out the engine to make willy-waving bigger power then I could have gone to any number of people. The reason I went to RG is because of the re-engineered head that ditches the Finger-followers and adds extra coolant and oil pathways. I'm not really interested in extra horsepower as such - I'd happily forego that in favour of better reliability and tractability.

But, please, by all means gloat if that makes you happy. rolleyes
Eh, No gloating from me, you were the one posting about the delays!!I couldn't wait that long simple!!

Read the last line in my post AGAIN!!

Perhaps it came across differently to how you intended - text is very imprecise and open to misinterpretation. It seemed to be sarcastic, but if that's not how you intended it then I'll happily accept that. hippy

Update: If I had "a couple of weeks" left to live, I'd want Racing Green TVR to be responsible for determining how long that actually was, as I could end up living for a month or more.

(In other words, still haven't got it back yet or had any indication when it may be)
You certainly have a great deal more patience than me!

They are both solutions to similar problems but from very different angles and as such will suit different customers.
Indeed. Almost like McLaren (all technology and engineering) vs... actually, I'm not sure... it would be a disservice to say something American but it's almost that ("no replacement for displacement") but hopefully people kind of see where I'm coming from.

Actually, I do think the Speed 6 is lacking low down grunt, so perhaps I should have considered another route, but I'm convinced that the technology of the FFF2 head is the way forward on realising the potential of this wonderful engine. Perhaps at a later date I will have it bored out to give some more low-down torque but right now I want to address the inherent flaws of the standard head.

I wonder if changing the cam timing to trade bhp for more torque at the lower range would be the solution?

The VCT system would be an added advantage for doing this but I reckon that's still a while away from a customer ready solution?

Yes, the VVT looks very interesting but I agree that it will have a way to go before it is something I'd consider. Hats off to the early adopters who will do the R&D / fettling / beta-testing of it though.

Having had an engine failure due to detonation on #6 cylinder, and another due to a valve seat falling out (yes, really), I would say that there are some inherent flaws in the standard head. More than just an "old chestnut" in my opinion.

Other firms seem to do well out of pre-oilers...a need also gone from this engine. Just like the fingers.

The Finger Followers Are not a problem, its the using the incorrect oil and lack of oil to the cylinder head
thats the problem.

I think Jason's and Dom's rebuilds involve increasing the oil ways?

Having said that there are some stories on here of FFs still breaking at high RPM. I think someone had a rebuild do this at the recent VMax?

I have to say it is great pleasure to no longer have them. If only for being rid of that horrible noise. biggrin

I've been out in mine this morning and it's just so silky smooth and refined and oil pressure is just totally constant. None of the dropping to single figures on tick over.

It's as smooth as my mass produced 130 shopping cart.

By using the correct oil and upping release valve spring rate and setting the tappets correctly you will get good pressure and a quiet engine.

Me too hopefully. And dpd, we've figure out that 20 years of running the FFF will save the cost of the conversion when not having to do the tappets! biggrin

Slightly off topic but Out of interest which oil is the correct oil to reduce these probs. I'd love to get a definitive answer with reasoning behind it but have failed to find one so far. Mines been using Mobil 1 0 - 40w but am getting tempted to drop it out on the info iv picked up off here.

Yep. And as I see it we have nothing to lose and a whole lot to gain. The only issue has been the time taken so far. But now that the heads are happily in production the main barrier to getting the VVT finalized has gone.

I popped into RG on Wednesday and had a good chat and they will be working on the first head to have the kit fitted next week.
