i was wondering if the Vp 109 octane rating is to much for my modded turbo? or is it an overkill and should stick with 103 octane?

are you refering to vp's MS109, if so MS109 actually has an octane rating of 103 just with more cooling properties than their standard 103.

 

Yeah im refering to MS109 , i guess then its the way to go..??

 

Hallo


We try all vp fuel on our 911, from streetblaze to MS 109 / / /

Street blaze *(MS100) the best. Have big different with other fuels

 

With MS 109 you need to change your software for another ignition

 

I alredy have diffrent software and bigger turbos...

 

The MS109 burns cleaner but also faster. The price is usually the same so if you want the best performance, go with the MS109. the VP 100 is also good but not as consistant as the 109. Its cheaper for a reason and the MS 109 comes in a sealed container where the 100 is usually at the pump.

 

MS109 has 109RON, similar to 103 US octane number (RON+MON)/2

 

Call ur tuner!!...I would go with MS103 coz MS109 will make the car leaner

BTW....How many hp/tq with RUF modded vtg's?

 

Sorry that is wrong -it is not 109 Ron--often been asked why it is called 109-when it is not.

 

Ms109 ( ron ) = 101 ( mon )
ms103 ( ron ) = 99 ( mon )

 

600 Hp , 850 nm of torque....

 

What kind of mods to get that torque?

 

Upgraded VTGS ( More flow than GT2 Turbines), Ruf Exhaust , Ecu , BMC Air Filter , Special Spark plugs..
