i've got some good deal on the NOS Octane Booster (Racing formula) - works like a charm for the POS 91 octane gas we get here.

 

I swear, Tan MUST be the ONLY person on this board who spoils his car more than any other owner. Other owners spending thousands of mods and their cars drive better. But his car *loves* him so - his car only sees racing fuel! *laughs* Of course, unless he's out in the middle of nowhere and has no bars left.

 

This is strange, every mechanic I have met has said the same thing about octane booster. That it does not work and it is not really harmful. I can tell when a customer has been using octane booster as it leaves a strange brown stains on their spark plugs they don't fowl but they smell off. Also when the bottle on NOS octane booster says boosts 5 points of octane it means 0.5 true octane. You can tell a difference when adding it as most of them have a cleaning agent which has a better effect then the octane boost. I personally recommend cutting the gas you use with 100 octane if you 1/2 with the standard 91 if you have the cash. 4.50 a gallon is a lot to pay for gas but if you can afford it then it really is the best solution for the piss water that they sell in california.

 

Hmmm, I pay 4.39 every day, for regular 95 octane, so what

Another un-scientific test:

After Mingster's restaurant tour, I added 5 gallons of 76 Racing fuel (100 Octane), then filled up with Supreme Unleaded (91 Octane). This should give me a mixture around 95 octane.

The route I took was I-10 West, then PCH North. The outside temperature was about 60 deg. F. I am aware of the fact that our engine perform better with lower ambient temperatures and I've done this route many times under similiar weather conditions. Today; with the higher octane gasoline, I feel the engine perform noticeably better than usual. The engine appeared to have more torque at lower rpms, and rev smoother at higher rpms. I plan to use this 5:7 mixture for future runs. If someone in the future decide to do a dyno test on the effect of higher octane gasoline have on the F20C, I wouldn't mind contributing something to the effort.

"Octane" numbers for fuel do not measure the concentration of the hydrocarbon octane (C8H18).

 

The Sunoco station on the corner of North Jerusalem Road and Bellmore Road in North Bellmore (Long Island) sells Cam II race fuels from the pump.
