Race gas

[Winder_506]

Wanna run my max 20 tune sometimes on my ‘20 le. Have all the supporting mods to go with my dash reflash, question is to the racer guys out there, local shop sells VP race fuel, c-12,14 and 16. What’s the ratio race gas to 91 pump gas to get min 97octane to run race map thanks and marry Christmas the guys on here are great

I've been told if you mix 110 at 20% you will be good to go on max 20, but many on here with much experience will probably share expertise.

Best fuel to mix in there is c16 run about 25-30 % u should be safe thats what I run for testing

Figure everything on 10 gallon tank and find average. For example:

7.5 gallons x 91 octane = 682
2.5 gallons x 116 octane = 290
682 + 290 = 972 ÷ 10 = 97.2 octane

So you need 2.5 gallons of C116 with the rest of the tank full of 91 octane.

Using the same formula, if you put 3 gallons of C12 mixed with 7 gallons of 91, you would be at 96.7 octane.

Figure everything on 10 gallon tank and find average. For example:

8 gallons x 91 octane = 728
2 gallons x 116 octane = 232
728 + 232 = 960 ÷ 10 = 96 octane

So you need a little over 2 gallons of C116 with the rest of the tank full of 91 octane.

Can we rename you GASMAN?
FLEECER sounds like a guy that wears ugly sweaters.
GASMAN has PIZZAZZ!

Fleecer is right on. Also, Google octane calculator to brew up any mixture.

If you do a search under my user name with 'octane' as the keyword you'll find an Excel spreadsheet I wrote to calculate this.

Thanks guys. I Google most everything but asked here first. Found what I was looking for now to fund it all at 220$ cad for 5 gallons of 116. Be a fun couple rides. Lol
