Very interesting!

Thanks for the snaps and commentary.

Car looks great by the way - I look forward to the final technical instalment too.

Indeed, have you put wky aftermarket Halfords special DRLs on your lovely DB9? Why, God, why?!?!

EFA

Bandwagon jumper........WRONG!

Your DBS is only producing 447 BHP. You have serious issues

I dont believe I have claimed it's a DBS? In actual fact, the dyno printout shows DB9.

I will be finishing my intake and breather mods in the next few weeks, so why not bring your new DBS down and lets see how much power it makes compared to my measley DB9 on the dyno, instead of just reading the spec sheet? Lets see how much it really has.

Up for the challenge? We can see then how accurate the spec is compared to the actual after transmission and tyre losses are accounted for.

Still waiting to hear from you to see how much power your DBS really makes!!

Here's my fake one yesterday...complete with stock exhaust manifolds and 4 cats still fitted, so I still have a way to go yet.

I do apologise.

Sadly for you I use my car for driving not willy waving competitions.

Best of luck with your project.

Give or take a small percentage (such are the allowances of on the day homologation testing, which for DB9 and DBS and V8V I might have done the actual power homologation tests in front of vehicle certification agency, or I might not have done, couldn't say either way, probably not allowed to), surely every DBS will make 510 BHP @ flywheel seeing as that's what the auto maker homologated? Anywhere between 490 and 530 would be fair game in market, as would 430-470 on original DB9.

Fair play for having an ameteur crack at performance development, given the wide band of absolute headline power numbers possible for outright performance, I will reserve my comments on your claimed figure, it could be right, it could be wrong - but I do have a well informed professional opinion! What is utter horse ste though is your peak power speed, absolutely no way the spec you have could 'physically' produce peak air consumption (therefore peak power) so high up the Rev range bringing the whole test into question. With the base engine spec you have you could take the throttle away completely and run (on a dyno) the inlet manifold open to atmosphere, have 1meter long exhaust primary pipes and no cats - and not even then would the peak power speed be what your result states - that's how far wrong that curve is!!!

As you mention it, what was your wheel curve, because your result states flywheel meaning there is a correction curve going on we can't see?? I ask to be helpful, because Somewhere your test has fallen over, it could be in that calculation? If wheel power is peaking as high up the Rev range as calculated flywheel power then unfortunately the whole raw data-set is horse ste too, as well as the calculated post coast down curve.

Post up your mass airflow recordings from the cars own mass airflow sensor, you can do that running the car down the road saving the bother of dyno testing. Airflow in must equal power out (with a few exceptions) and from my database of data you punch up an airflow figure, I will tell you the BHP. Much more scientific and avoids the horse ste! But I sense you won't do that and continue form of posting dubious dyno test after dubious dyno test. Where are all the engineers gone? So hard to find stuff being done right these days.

Boom.
