PMS just got their own version of THIS working in this years 919... I imagine we'll see it in whatever comes after the 992.

I'm surprised of the 7K redline - it's lower than Turbo S, which is at 7250

There's absolutely no way this car will be able to go 249MPH.

Old cars generally hate alcohol in fuel (even the E10 that is everywhere) - they have many rubber lines and fittings that disintegrate). But any car newer than 10 years typically does not suffer from this.

10% Ethanol on the 4G63 is fine (I used to run it on my Evo too) but E85 is another animal.

I have seen an 4G63 engine on E85 with clogged injectors and when pulled apart, excessive deposit formation inside the engine.

Apparently an engine running on E85 is very sensitive (much more so than straight gasoline) to how the vehicle was driven with regards to the rate and level of deposit formation.
