Race Gas fuel additive.....
« on: July 31, 2019, 10:22:22 AM »
I decided to give a can of this stuff a try just to see what would happen in my aluminum headed 10.3 compression
427 Windsor after reading and hearing about results of it.
Bought the 16 oz. can and dumped it in about 8 gallons of fresh gas in my tank.

Over the weekend I have noticed that the engine will cruise a bit smoother in 5th gear/3.50 rear gear 45 MPH @1500 RPM.
Also noticed the engine temp runs a little cooler.
Can't really tell if there was any improvement in additional power but it just runs smoother at lower RPM.
I left the ignition timing where it was at 32 degrees total.

So at 18 bucks a can it's cheaper than race fuel and might just be adding a can now and then.
I have always been running straight 93 pump gas in this engine since I built it almost 10 yrs. ago.

Is that the actual name? Race Gas?   I am assembling an aluminum headed  engine now and the CR will be down from 11:6 to 9.8.  I hate buying 110 at 9.75 a gallon to mix with the 93 octane. 
I am surprised there is no pump 100 here in the Dallas area.

VP Racing product called Mattive is real good octane booster to mix with 93 octane , it can turn 93 octane into a 100 octane if needed . Is this what you are using ?

Does anyone have reliable test data scientifically showing octane booster in a can added to low octane fuel is equivalent to the performance of a higher octane gasoline?  And which brand offers the best bang for the buck? 
I know all the octane booster companies make bold claims about their product. I’m just curious if they have been tested and if so are their claims true.

My brother went from racing fuel to pump gas with Madditive Octanium and noticed no ET difference on a 12.5 to 1 347 SBF Maverick  running 6.70's at 99.9 mph in the 1/8th mile , he's been using it over 5 years now , he was mixing it for 101octane  but now he's down to a 98 octane mix . I have quite a few customers running it in their vintage muscle cars

Not for nothing, it kinda sounds like the 5th gear doesn’t have enough timing to properly burn a lean cruising mixture.

If the additive works, great.... but I think you could tune out and that little issue.

At 9.8:1 you are easily within the margins for being able to use 93 with no ups or extras.  Unless you (or someone else) really screw up the tuneup.

Anybody try toluene? In the past, F1 racers used high levels of T added to gasoline. It's relatively cheap at paint stores btw.

More here. T scored very high btw.

Cute article but there is no exact science on what quantity per gallon. It can be detrimental in the wrong quantity and also is caustic to any rubber in the system. it will destroy fuel hose and needle valves.

America was a much better place when Sunoco 260 was just around the corner for 32 cent! 
Miss my "old" country! :(

I had to stop and think what I remembered fuel at. I was born in '66.  When I started driving in 1981 it was about .79 for regular in So Ca.

As will alky, nitro and other additivies. Yet, in modern EFI applications, some using E85, zero rubber in the fuel lines (SS, lined or both) and of course, no needle/seat valves.  Some say 5-20% is 'right' as a great octane booster.

'Course, one could do some searching and find a lot of references on the exact science....if they cared to give T a whirl.
