Yesterday, Jalopnik user CASINO199 asked in !!!error: Indecipherable SUB-paragraph formatting!!! what a Porsche 911 Turbo flat six engine might sound like if it was made into an F1 engine. He linked !!!error: Indecipherable SUB-paragraph formatting!!! as an example. I couldn't help but try and find out.

!!! UNKNOWN CONTENT TYPE !!!

So I got the audio from the video and got to (lazy) work with Audacity. I made a really rough mockup I made of what a Porsche 911 Turbo flat six engine might sound like if it could rev to 15,000 RPM. I went with a rough estimate of a 6,000 RPM redline for the engine and using Audacity, increased the pitch of the audio by 150%. That equates to a 2.5x RPM increase, resulting in 15,000 RPM. The mockup isn't that great because the background noise was also changed in pitch, and overall it has a strange digitalization to the sound, but it gives you decent idea of the possibilities. So here's the result:

Putting aside the fact that I really have no idea how high the Porsche 911 Turbo rally car in that original video can actually rev, I think it came out OK. I ballparked it based on the max RPM's that the 2014 911 Turbo can achieve and subtracted about 1,000 revs. I actually really like how it sounds at higher RPM. It reminds me a bit of a gas RC car at lower revs though. Overall, I feel that it's way better than the crap we're actually getting for 2014 F1. I doubt though, that a 911 Flat Six would actually sound like my mockup if it was engineered for real to rev this high.

Hooray for lazy Audacity edits!

To reach F1-level mean piston speeds at 15000rpm, the 930's stroke would need to be reduced to around 2.5 inches. That yeilds 2.64 liters. This puts the output at around 420HP N/A. At 80s F1 levels of boost, at least 35psi, yeilding around (drum roll) 1570HP.

What's interesting is that the 917k's 1500HP engine was pretty close to this configuration, but with half the RPM and twice the cylinders.
