Thanks.

I'm certain I'd get more than £6500 worth of enjoyment out of those manifolds so it's going to be hard to resist for me.

Thanks also for your huge contribution to the project. Subsequent customers will all be benefitting from the research and development you commissioned.

Just out of curiosity what affect ( if any) do these mods have on insurance premiums?

I will post up the actual graphs later when I get them and then next Tuesday the difference with just the exhaust and by Thursday with Exhaust / Cams and Finally Monday 15th with the Exhaust cams and inlets.

Anyway headline figures are:

Factory published:
570Nm @ 5750 rpm
510 BHP @ 6750 rpm

Actual JON70Y:
556Nm @ 6000 rpm
507 bhp @ 6750 rpm

So I am already in the 500+ club wink

All V12V and DBS owners Keep watching.

Nice to see it not far off the AM published figures!
You do realise all that extra power will result in deeper stone chips wink

Well exhausts only fitted at the moment, cams tomorrow. I will have some graphs for you all to see tomorrow also.

http://www.youtube.com/watch?v=dQaldT9NsxQ

Headline numbers from the exhaust are +33BHP so from 507 to 540 BHP @ 7000rpm

Torque up 40Nm across the rev range & 591Nm @ 6100rpm

Ooh almost as much torque as a DB9 wink

Sounds fun though, am really looking forward to hearing the low grumbly engine sound rather than Yeti's high pitched one when it's all done smile

Well a high pitched one.... But I prefer the sound of the slightly less high pitched V10s of old. And prefer low, grumbly exhaust notes even more - TVRs, Astons and AMGs etc etc smile

it will have more by tomorrow George and then we will experiment with DB9 inlets for approx 630+Nm on Monday wink.

It will probably be 550BHP with cams and around 600Nm, but with DB9 inlets it will lose some headline BHP for another bucket full of torque. Mike sounded like a child with a new toy on the phone, sadly for him I will be taking his toy away on Tuesday.

That'd be ideal for outrunning the Sweeney after you've done a blag!

Pleased with those numbers? I reckon you should be! Are these still the standard short inlet manifolds rather than long-tract DB9 ones, or are they going on with the cams?

The best sound actually comes from the safety car these days.
