Bamford Rose engine wins AM Global challenge

Can you imagine what a BR tweaked Vantage S would be like then ?
Honestly I am living the dream over here in sunny Hereford

And all that's sorted on yours is the breathing at the moment Rob... Imagine the results when they get at the engine internals as well

Hey Rob welcome to the revolution ! How can Molly say no when she sees you smiling from ear to ear !!

Rather looking forward to having what is basically a Le Mans GT1 winning engine in my car... only even bigger. And therefore better

[yeti]

So do the regualtions state that the car must have it's road-going engine i.e. a 4.7?

Or could the soon-to-be-developed 5.0 (or thereabouts) see it's way into a racing car in the future?

[mikey k]

Mike did say i will be used in a couple of race cars with certain restrictions

[yeti]

Does anyone know why Aston didn't jump straight to the 5.0 from the 4.3 launch car when producing the updated Vantage? Wondering if it's ever been mentioned on factory tours and so on.

What I found with my car... originally we were going to rebuild the 5935cc engine to BR spec and make around 100bhp/litre. Then BR said 'why not go to 6.5' and looking at the numbers, it costs no more. Pistons and so on are a unit price, slightly bigger ones cost no more and you get free power and torque

Does the 5.0 require a different crank maybe?

How many people upgraded from 4.3's to 4.7s?
How many would upgrade to a 5.0?

Perhaps because the 5.0 V8 is only used in supercharged form? The 4.2 V8 is the N/A engine, and when supercharged and bigger CC it would probably be as fast as the V12V. They probably chose the 4.3/4.7 to slow the Vantage down.

Actually you're probably right - even Aston and the global regulations they have to comply with would struggle to keep a 5.0 engine below 450bhp... Dangerously close to DB9 territory...

Jaguar supercharge their 5.0, doesn't mean Aston have to though

I'm sure it's a lot less work to bore out the 4.2 to 4.7 than to de-supercharge an engine though?

Eh?

It's the same block - my question was why not take the 4.3 straight to 5.0 and am now wondering if that's what will be in the Vantage replacement? If indeed they do replace it...

Exactly my point marketing positioning it.
The BR 5.0 NA does not need a new crank.

So the Aston one won't either... So next Vantage probably 5.0 with 440bhp or so (DB9 at 510 so a decent gap). And a BR 5.0 making what... 500ish, a smidge more?

Love it

[mikey k]

I reckon next Vantage will have a different inlet manifold, I vaguely recall someone saying they had testes a 4.7 to 470 BHP
You know how AM like to drip feed improvements a 5.0 would be a big leap IMHO.
The BR 5.0 will be ~550 BHP
