octane boost versus 2 gallons of race gas

[mountainhorse]

Also a point to mention...

100LL has a MON rating of about 103/104

110 Race has a MON of 106/107.

Race has more lead in it.

Premium pump (usually 91 R+M/2) has a MON of around 87/88.

So... If you are shooting for 91 or so MON then you would need around 3 gallons of 100LL plus 8.5 gallons of pump premium.

Here's a decent Octane/Mix calculator.

you don't need race gas or octane booster to run that kit. if it was a 13 yes a 12 no. just run it on premium and see what happens. if it starts going into det mode you may have to add a gallon of 110 per tank.

Says one bottle to ten gallons 96.6 mon rating from 93 octane not 91-97/98

"When mixed in a 100:1 ratio of fuel to additive the Lucas Octane Boosted averaged a RON reading of 101.4 and a MON rating of 91.8. Giving Lucas in a concentration of 100:1 an AKI of 96.6 when mixed with 93 pump fuel. With a ratio of 100:1 this make Lucas the most concentrated additive.

When used an a concentration of 50:1 103.1 RON was achieved with a MON of 93.5 giving it a AKI of 98.4.

To date Lucas octane booster is the only booster tested that had significant results with only one bottle in the tank. One bottle is enough to make 10 gallons of 96.6 octane out of 93. "

they don't give a mon for the torco but looks like about 95 mixing to highest recommended concentration according to the ****ty chart they have there for ten gallons mixed.

yea guess 6 points is a tad high...here was the N.o.s specs..

When mixed in a 60:1 ratio of fuel to additive the NOS averaged a RON reading of 102.8 and a MON rating of 92.5. Giving NOS in a concentration of 60:1 an AKI of 97.6 when mixed with 93 pump fuel.

When used an a concentration of 20:1, over the recommended maximum, 102.6 RON was achieved with a MON of 93.1 giving it a AKI of 97.8.

The results from the NOS booster seemed a little off, but they were later confirmed. No matter what concentration used NOS would not boost 93 pump over 98 octane..

anyway interesting stuff..

I am running the Northstar kit and was told not to run ethanol fuel if at all possible. Need to run 91 non eth. If that is the case with these other kits, and only 88 non eth is available, then you need to do something to bring it up to 91 non eth. I did have to run a couple of tanks of 91 w/ethanol last year and did not see any real issues but seems to run better with the non eth.

I am running the stacked kit from Jeremy. I do believe I found a race gas connection here in cda. thanks for all the help folks.
