Hi

The 100-200 is a torque discipline

Better times gets my R8 not down because a rear-wheel drive

I would be concerned that increasing the throttle area by over 37% is going to create all sorts of air mass speed issues and make part throttle driving at best "twitchy".

Bigger isn't always better.

Hi

The reconstruction of my R8 was first on [74,5mm] throttle valves and finally onto the 82 mm end flaps


All data here are with [74,5mm] throttle valves except for the last ones here

Hi All

In the course of the further increase in performance at the R8 V8 engine, intake valves with thin staff are installed.

Exhaust port extended

A processing of the inlet ports and exhaust ports for better cylinder stuffing is also carried out.

A lot of work to gain how many horse? Why not just buy a V10 instead?. :biggrin3:
Too much power is barely enough.

Hi

Target on 500PS

With a V10 motor can no longer improve and thus boring
