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.

Ms109 has a different stoichiometric value than pump gas.


I'd throw 5 liters into 10l.

Thanks for the replies, I didn't get a chance to go out and get some so ill run it tonight on 98RON and see how I go, then try MS109 next time.

Ran an 11.8 tonight on full street trim with Michelin PSSs. Pretty happy with that.

What mph Charlie??

Got any videos

charliekay

120mph-121mph over a few runs.

Got some GoPro videos. I'll edit and upload on the weekend.

With some slicks and race fuel and a good launch you will see a very low 11 high 10

mr747

mthis

mr747

Mthis Charlie has a full ipe exhaust as well

charliekay

Thanks mate.

I have an IPE full exhaust with an OE Stage II tune.

Here is the time slip.

mr747

1.8 is good for street tyres

Well done again

mthis

My bad, missed that part, either way good time.

Get some Dr's and race gas and u will see a good change.

Here is a video I put together of a couple of the runs.

RNS-11Z

Not in Australia with tune and exhaust only. You will need 300kgs removed, race tune and full slicks to go close to a 10.

mr747

Ill let u know how I go lol

Yeah it's hard but it can be done

I'm gona get some tyres and give it a crack

When are you coming back home to give it a try???

RNS-11Z

That's it for now until I do more mods. Good luck on that hi 10. Heathcote is a fast track, better times then syd and willowbank. I predict youl go 11.4/5. Any quicker friggin awesome.

mr747

11.5 ill be happy

Zeee_Q

Were you in Sport mode or Manual mode during those runs?

charliekay

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.
