AutoCar - New TVR V8 first dyno test
Discussion
V8 GRF said:
I think the regulations for LMGTE as it will be called limits the engine to 5.5l and there are varying sizes of restrictors depending on the capacity of the engines and that obviously limits the power but I believe that is in the region of 500bhp. So I think it's likely that the roadcars might be actually more powerful than the LeMans cars. I think that was the case with the McLaren F1 as well.
Regulations with the relevant engine part in section 5.1 and restrictor sizes in Appendix 1 CLICKY
Where did I hear 700bhp from - was definitely at NG open day. I was chatting to Les duringthe day, but lots of others as well... Had it in my head for some reason, powerful car for le mans, detuned for the road carRegulations with the relevant engine part in section 5.1 and restrictor sizes in Appendix 1 CLICKY
Those specs (2015) also say the exhaust must exit aft the middle of the wheelbase - and we know that's not happening
Aston Martin GTE is over 600bhp and 700nm torque

With regards to power I've struggled to find any references by way of comparison to what is produced by the classes of car. The Aston produces that power from a 6 litre V12 and those regs state the maximum capacity permitted is now 5.5 litres with different restrictors with changes again for 2016.
So I dunno. I'm confused.
but hopefully we'll be told what power they're going to produce once the dyno work is done.HarryW said:

Yes it does have simalarities to 4.6 we are all aware of that and we also know its a completely redesigned engine, now this engine can be supercharged and there are kits available for it upto 50% more BHP over standard the ProCharger kit @ 8 psi of boost is making over 700 BHP.
Do we think TVR will leave enough physical space for a charger, if not for their own upgrades But after market?dvs_dave said:

It's a very detailed piece about the Coyote which first appeared in 2011. Yes there are similarities to the old 4.6 but it explains that it's because they didn't want to have to re-tool the engine plant to make it. So things like the 100mm bore centers remain, and a few other critical dimensions were designed to match the old 4.6. But it is a completely new ground up engine with no component commonality with the 4.6.
Thank you for posting that link, it is a very interesting read. Its a beautifully engineered engine with lots of potential for Cosworth to stretch its legs. http://www.mustangandfords.com/parts/m5lp-1003-201...

Yep, although I only understood about 5% of it. 
Interesting looking article linked at the top, haven't read it yet, but might make interesting reading!

The Charger is very compact and it sits to the side of the engine so it should clear without any body mods i think the transmission is going to be a C/R TKO 600 box so it will take the power.
Les has mooted previously that FI, specifically supercharging, would be used for future models so clearance must already have been considered. Although I'd be very surprised if a procharger centrifugal type solution was implemented. They're pretty pants from an engineering standpoint when compared to proper roots type blowers. All the disadvantages of turbochargers and superchargers, few of the advantages. They're relatively simple for aftermarket tinkerers to fit though, but there's a reason they're never used for OEM applications. Also there's plenty of bolt on roots type blower kits already available for the Coyote that pump out 700hp+ and cost only a few grand so a centrifugal blower lash up would be an odd choice.Edited by dvs_dave on Saturday 17th October 21:08
Agreed, it's a superb engine with HUGE potential, more so than any other engine ever used in a TVR. I'm pleased it was chosen over the Chevy LS which was the only other possible choice. A voodoo version may appear in the future if sales and racing go well, and I reckon it would most likely be in a GT3 type LeMans special edition which would be super cool.

And, of course, TVR have history with Ford power.

I agree. The Ford unit seemed the best choice on its own, given bang for buck while carrying much less stigm than others. Adding the Cosworth label to it was very smart. Of all the engine brands, it keeps the UK angle and is synonymous not just with some of the great racing engines of all time but because of cars like the Escort it has the same market appeal that TVR had.

dvs_dave said:
What does the number I have fitted or driven got to do with it? If I am mistaken with my comments, then please enlighten me as to why
What engines have you built or supercharged then 
The problem here and no dis respect is these are all "comments"... We definitely need a pub talk thread.

In a recent evo mag they had a short article on the flat plane crank ford v8. Power wasn't huge (compared to a European flat plane v8). They referred to it as a good starting point. 102bhp per litre v 125 in a 458.
Comparing, and then saying that the engine from a $50k car is not quite as good as the one from a $250k car is a bit silly. Although the Voodoo is still emissions compliant, the F458 is not, hence its discontinuation. Sheds a different light on the matter when you consider that....m4tti said:

We've had this discussion before haven't we? Rather than scoffing and dismissing things as pub talk, please make the effort to enlighten the room as to why. And don't be afraid to get technical
Not afraid dave.. Just typically base my opinions on experience hence I'm not that vocal on the coyote. Also quiet as I'm mapping out my next build, rather than re-gurgitating the interweb. Have you put your build thread up yet
