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.

This is the stuff...http://race-gas.com/
I can get it at the local Pep Boys Auto.

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.

Has anyone tried this stuff? Boostane.

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.

A gallon of VP110 at the track here is $9.50. Mixed 1:4 with 91 pump fuel = 94.8 octane fuel. I don't see the "race-gas" it as that cost effective, personally. Plus you get the same effect from my experience - car is more consistent with 1~2 gallons in 5 of pump fuel.

I used to have a 93 inch dual plugged Shovel head Harley back in the early 90's that made 145 crankshaft horse power built by Brad Oehler ( Brads son is Flying Ryan Oehler on NHRA PS bike category) and I could not kick start it with race gas when cold as it just wouldn't start had to push start it until warm then I could kick it , put some 87 Octane and I could kick start it one kick every time cold hot didn't matter , the OP really shouldn't need race gas with his compression ratio and aluminum heads ,

I run 16 gallons at a time. It's a street car. I was using 50/50. No opinion with over 11:1 on the street. Even with the 9.8:1 I'm not sure I want to just run 93 pump.
-
I run straight 110 in both the 10.5:1 and thee 9.5:1 motor if at the track. Has nothing to do with ET or MPH, has everything thing to do with dialing the same number as much as possible. The 9.5 will run just fine around the streets with 91. The 10.5:1 351C used to be OK on 93. 93 pretty much disappeared, but before it did there was evidence of slight detonation. The 10.5 could run on 100 but the track only carries 110. On a 2 day race weekend, yep I can run through $100 of fuel easy.
-
Just wanted to give the stuff a try and see what it would do! Might be it just makes the pump gas burn a bit better or maybe it
has an effect with how fuel atomizes in a carb setup.
Maybe do a test again with straight 93 pump gas and then with the gas additive and see if the A/F ratio changes using my meter.

When did Sunoco 260 disappear and what was the octane
