Octane Booster

[Justin@VMP]

So in plane english you are saying you need to run a richer MAF Transfer on race gas compared to a street tune?

Well, you need to change the stoich point in the tuning software. Some will let you do this, but in some you may need to adjust the base fuel table or wot multiplier. Your maf xfer should be correct so you don't want to go and make it inaccurate (and make load inaccurate).

Does anyone know what is the best Octane Booster that really works besides Race Fuel of course or is it a waste of money????? The last stuff I tried was by Champion and it said it was the max for street use up to 15 points, so that would put the pump gas 91 to about 92 or almost 93? Right?

In older cars with a performance engine I would use torco to prevent pinging in the summer or just pull a little timing out. But if I were trying to add octant booster for more power then I would only use 109 race gas and have the car tuned for it. Otherwise your just paying more for the gas if you don't get it tuned for the higher octane. So IMHO it just depends on what your are trying to accomplish as to which one I would recommend. Just my , for what it worths.

Thanks



At a shop I worked at back in Indiana we did a lot of testing on this subject. We tested different boosters for power on the dyno, at the track, and in the hot humid summers back there. With aggressive timing and bumped up compression you would get a little pining on the street with pump gas in the summer, but a little torco would cure it without the loss of power you get when you pull timing. And torco was the only one that actually helped in all three areas. BUT I WOULD NEVER use it in place of race gas for a balls out tune for the track. Race gas does make more power when tuned for it, a lot more.
