AutoCar - New TVR V8 first dyno test
Discussion
The Ford engine is a lot bigger due to its 4 Valve configuration its higher and wider than the LS you would have job fitting it into a TVR chassis.
and as for the flat plane crank you would have to change the camshafts as the lobes will be in the wrong place for 180 degrees instead of 90 degree.

Be good to know what Cosworth are doing, make no mistake my question is not a critical one of them or TVR but one born from interest in what's to come.
I've had a read around some of the American sites and it seems the basic engine is a very good one but not so good it doesn't have scope for improvement. I suspect the headroom for improvement is such that gradual upgrades could be released as the model(s) evolve. I'd like to think the LE whilst not the ultimate performance model will be north of 450 if not knocking the door of 500. The last thing they need for the release model is unreliability though so it won't be pushing the envelope...

Regarding the Ford engine making the new TVR a kit car, does anybody consider Morgan cars as kit cars, especially the Aeromax or Aero 8? I know the Aero 8 uses a beemer V8, and not even in the M5 tune.
Never mind Morgans, apparently my Audi RS6 was a kit car 
Engine designed by Cosworth
Suspension designed by Yamaha
Interior designed by Recaro
And don't even get me started with my Kit Car Mini Cooper S with its French engine.
The Coyote isn't a flat crank. The Voodoo which is a version of it has the flat crank. Neither share anything with the the old 4.6 modular V8 engines other than the factory they're built in. They are new from the ground up.
The Coyote block has been designed with supercharging or turbocharging in mind. It is also able to accommodate Direct Injection, although doesn't have it currently.
We probably won't see a flat crank initially but we may later on. Perhaps in a GT3 type iteration if business goes well.
It would be though cool if Cosworth were developing a Direct Injection system for it. That would make it unique, and would explain the need for a bespoke ECU. The DI parts are off the shelf and easy to implement if you know how and the block is designed for it (which it is). That would open the door for higher compression ratios and more NA power that way. DI also works very well with forced induction.

...and one of the cam box covers is marked "Powered by Cosworth".
That's the key thing. Les Edgar is no fool - the reflected halo glory of the reputation of Gordon "McLaren F1" Murray and Cosworth are worth a hell of a lot, regardless of actual input.

The Block is virtualy the same as the 4.6 modular same deck height same bellhousing and bore spacing same mountings also the conrods are the same length the bore is bigger to get the to 5 litre the coyote block is stronger and the heads and manifolds are different so it has a lot in common with the 4.6 modular it is a further development.

700+ for the le man racer so 500 is the likely figureI've had a read around some of the American sites and it seems the basic engine is a very good one but not so good it doesn't have scope for improvement.

Have a read of this that someone else posted earlier.

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.

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?350Matt said:
so basically its going to come with an strong V8 engine that's designed for forced induction and will make 450ish Bhp for starters before modification
oh yeah that sounds rubbish
I can see why some are complaining.....
Do you know how the development is going...?oh yeah that sounds rubbish

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
