Nice video, some very strong cars, nearly as strong as my old boy first thing in the morning

These are the wrong way around, aren't they?Speedr8 wrote:481 HP (475PS)
If so, is it possible that there may be some other discrepancies with the figures quoted?

Hi
So that the engine gets air optimally, further modifications are carried out.

Re: light and strong Audi R8 V8
Do you know why air intakes use trumpets?
Re: light and strong Audi R8 V8
Hi
The air flows in above trumpets into the tube optimally.
Without trumpets shape the air throughput is reduced.

Re: light and strong Audi R8 V8
Almost - air flows in from above *and* behind the trumpet. This is why trumpets extend into an airbox and not sit on the side as like for like you get more air in and in a more stable flow.

Re: light and strong Audi R8 V8
Shorter intake trumpets would simply move the torque curve higher up the rev range. They don't change it (but anything really noticeable).Speedr8 wrote:Hi

This gives higher top end bhp but reduces low down torque.

411 at the wheels
so only 11% drivetrain losses?

On the 12.04.2014 JDEngineering which will optimize ECU and then will see
the comparison to the chart of the performance of the 14.06.2013
