A octane booster that actually works
Here locally we have 90 octane non ethanol available at the pump.
We run that in my sons 68 464 stroker and I use it in my 69 Corvette.
Mainly needed a octane booster for my Vette. She has the original 350/350 hp with its original iron heads. GM advertised it as 11 to 1 compression.
No matter what you did to the timing or adding over the counter octane booster the 350 still pinged, I just learned to keep my foot out of the pedal over the years.
I read about a booster called Octane Supreme...... do I dare say on a Corvette forum.........so I ordered up a case.
According to the label on the cans it contain real lead. I followed the instructions for raising the octane by 8 points.
I took the old girl out for a 2 hour drive yesterday. Let me tell you she hasn't run this good in close to 40 years tho I did have to reset the timing, she wanted to run on after turning her off and with the booster the idle picked up 300- 400 rpms. My car has the original side pipes and the exhaust fumes even smell different.
We also tried some in Brents GTO. We raised the octane by 3 points.
What we noticed mostly after adding the booster to the GTO was the improvement on start up and idle.
Anyways I am sold on this stuff, especially for those of us that have original high compression iron headed cars.
