light and strong Audi R8 V8

It's again assuming the credibility of the 481ps. It is meaningless without independent testing or benchmarking. It also doesn't help that you are commercially involved as you have posted adverts relating to this.
This is nothing personal but we have all been around long enough to not accept anything without proof.

How many bhp do you expect to gain through the valve thinning and polishing alone?

[Speedr8]

Hi

At least 15 hp and 20 hp are desired.

And additionally PS are expected over the custom exhaust manifold, homemade 1.4828

You'll need to wait until he's got enough credits in Gran Turismo so he can figure it out...

Hi

The result you do not accept anyway

I accept what Gran Turismo says, it's just a videogame so I don't take it seriously. It's when people try it on in the real world that it becomes laughable.

Back up your dyno figures with a quarter mile slip, otherwise forever be called out on the claims you make.

Will V Box screenshots suffice or does it need to be at the strip?

[bam_bam]

Both can be affected but at least the strip slip has some credibility. VBOX is helpful though.

[marc1]

Tom it looks like the challenge has been set! You have V Box I believe so round one would be covered. Round two at the strip for the ultimate shakedown. Will be interesting to see the results, but assume this is some time away as assume your car is off the road for a while whilst this is all being done?

Hi Marc

Yes, he's hibernating R8 and becomes the 01/04/2015 again make uncertain the streets.
A new engine tuning ( ECU ) is then performed by JD Engineering Holland.
After that I will go with my performance Box 1/4 Mile.

Hi

For a better cylinder stuffing the intake manifold accumulator is divided.









Tom

[Speedr8]

Hi
With the enlarging of the inlet ports and intake manifolds, a cross-section was reached of plus 19.8%.
Dimensions series in the smallest cross-section ( Tumble end flaps) > 1232mm², Tube smaller 40mm ( also Audi RS4 B7 )
After the processing > 1476mm², Tube now 43,5mm ( The V10 and RS5 have 1508mm², Tube 44mm )

I can't help but feel a little irked by the approach of some of the posters in this thread. Tom isn't exactly being bold with his claims, just stating figures that, ok, haven't exactly been proven, but are impressive nonetheless. JD engineering has a pretty good reputation, I'd be surprised if Jereon would let these so called "fantasy" dyno results be plastered over the internet with his name all over them.
