1/4 Mile & MS109
Hi guys,
Planning on going to do a 1/4 mile run tonight, just wondering if it is worth putting some MS109 in the car.
I have an OE Tune with a Stage II 100 RON file if I want.
If I was going to put some MS109 in there, do I mix it with 98RON (93+2) and if so what portions?
Thanks.
Charlie

Should make a difference. If you want to run race gas make sure the tank is as empty as you can get. MS109 is 109 research octane and I think 104 motor octane. It's also very oxygenated. Try not to blend much or you'll have to start thinking about specific gravity and stuff that'll give you a headache. If you must blend and want unleaded race gas that's close to pump gas as far as specific gravity and oxygenation etc try Shell URT Advanced. It's 110 motor octane. TrackTek makes good unleaded race gas too that's close to pump gas in consistency and is less expensive than Shell, though not as much octane.

I did 5 runs all up, the video is just 3 of them.
I did 3 runs in Sport mode (forgot to put in Sport+ mode) and 2 runs in Sport+ mode. TBH I am not sure which videos are Sport and which are Sport+.
None were in Manual.
All were with ESP off.
Brake, Throttle til around 1800rpm, when light goes green release brake, accelerate slowly til got full traction then full throttle.
