Thanks

you may see minimal gains because of the quality and oxygen content but not from the octane rating until you're tuned for it.

I'm running it with a Kleemann tune and saw about 17hp gain from what Cory told me.

How does that differ from VP109 and is there a benefit to it vs VP109?

ms109 is oxygenated and has octane rating of 105 compared to c10 which is non-oxygentated and is only 96 octane. the ms109 will make more power if tuned for it.

Here is the chart for "street gas"
http://www.vpracingfuels.com/spec/Te...StreetCars.doc
It is my understanding the C-10 has the highest LHV. (contains the most energy per pound)
Now I don't want to get in to a BTU/pounds per shaft horsepower dissertation on the fuels, because I have no side by side comparison on the E55, ie one may create more torque lower in the rpm band and the other may increase the peak hp. I just don't know, I do however like the C-10 and would recommend it.

according to the chart:

-"C10 – The best non-oxygenated unleaded racing gasoline available..."
-"MS109 - This oxygenated fuel produces more power than any unleaded fuel on the market..."

i fully understand and would prefer running a non oxygenated fuel for daily use in a street car, but for creating power i'd go with ms109.

Oh agree, 33 degrees TA or more with the 109, so the tune might be exclusive. "read for chiromikey's car only"

go to the VP site read the memo on the fuels you will see that they all say "WILL NOT HARM CATS" but the MS109 does not say this.. That being said MS109 is the SH*T and does make power.. used it for 3 months straight for daily driving..
