Put in MS109 race gas tonight.
Put in MS109 race gas tonight, About 3 gallons worth (total drum comes in 5 gallons) mixed with CA91 octane. There was a noticeable increase in power especially up top. The AFR at full throttle was a little rich, about 12.9.
But over all the car felt strong and pulled great with the increased octane.
Im going to try to mix in a full 5 gallon drum to my gas and see how much more power the car would get.
Off topic but...I was also monitoring the Intake temp it was reading around 117 degrees at 57 degree weather while driving. But parked it was reading around 170 (I knew these engines get hot but not this hot).
My friend was recommending I go with a water/meth Injection. I dont know how well it works on N/A engines but his 997 turbo was reading around 70 degree's on his intake temp. He also claims on really hot days (90+) the most hes seen the Intake temp was around 100 degrees.
Any thoughts about Water/Meth injection on the C63? Im really considering it..
The gas is VP Racing.

A vented hood would be a nice way to dissipate heat. But what I was thinking is if somebody made air scoops to put right in back of the grill so that would direct more air through the 2 snorkels that connect to the intake.

The fuel is oxygenated. With no detonation issues at all on my race bike it gains 4.5whp. A previous car I had gained about 20whp with the fuel and no changes to the program or boost at all. Needless to say it went way up when the boost and timing were changed. Of course, your mileage may vary...

Mixing 5 gallons of MS109 to 10 gallons of CA91 for example would produce around 95-96 octane. I was skeptical at first too but I did feel a difference in power, especially the next day.
If you don't think a higher octane makes power then go fill up your car with 87 octane.

The ECU will advance and retard timing as it sees fit to optimize for more or less octane and the presence (or lack thereof in this case) of dieseling. To really get the most out of high octane fuel you need a tune specifically for that octane...but I have no doubt that a stock ECU will advance timing to make a bit more power.

No, but the latest list of stations that carry 100 octane at the pump is here (mix with 91 octane to desired octane level). I've used four of the stations on the lis...the Alliance station on Sherman Way and the Car Wash in Long Beach used to be the cheapest of the bunch but they are all expensive now. 110 octane is available in 5 gal cans for around $75.

Dont know any pumps that have 93 octane but there are plenty that have 100+ octane.
Here is a list of all the stations....
