Look Its Aaron said:

Yea here in cali we dont get anything more than wattered down 91 octane :/

Don't mean to postjack: Aaron, are going to go to Fun Ford weekend in October? Its at California Speedway....thought I'd ask since you live very close.

unleaded gasoline = worst thing to happen to cars since RUST.

The lead additive acted as a lubricant which kept carbs in good working order and coated the valves to protect them from wear and high temperatures. Also prevented detonation somehow and made high compression ratios possible.

THEN some asshat got the idea that the lead particles coming out the tailpipes and settling along the roadsides was environmentally damaging. Which is utter BS even before you compare the damage done by salting highways, which no one gives a shirt about.

Unleaded gasoline is mandated, catastrophic engine failure from severe detonation and exhaust valves falling off brings the end to the era of efficient high-powered engines. Plenty of airplanes falling out of the sky around then. Automakers had to dramatically lower compression to make cars run on the damned stuff, resulting in the most pathetic engines since side-valve technology with no power and no fuel economy. Took 30 years for technology to bring car engines back up to the performance standard of the musclecar era.

Sorry for the rant, just trying to dispel the myth propagated by environmentalists that leaded gasoline was a bad thing. Unfortunately no you can't use the stuff in EFI engines though.

Yea I'm there for sure. They were going to have it at LACR but moved here to cali speedway. I live about 5 mins from the speedway.

Very interesting article! ... but has anybody here tried it?

I wouldn't have posted it if I hadn't tried it. It works good, just don't use too much of it during the winter months. It isn't very volatile, so it can be hard to get the car started with a cold engine. Summertime is no problem, as the extra heat makes everything vaporize much more efficently.

Sounds to me like your engine control/boost management system needs to pull some more timing at w.o.t.

Lead is one of the most toxic substances around - no way around it. Getting rid of lead in consumer products was absolutely the right thing to do. http://www.atsdr.cdc.gov/HEC/CSEM/lead/physiologic_effects.html Use some other method to raise your octane rating besides running leaded fuel.

Ya, the proper fix is a dyno tune.... this would be hopefully a temporary fix...

I was reading and I had to ask what is a system check for emmisions .... Isn't that your personal business if you want to unload toxins in the air? I'm 36 and live in northern Indiana next to Michigan. I've never been checked for emmisions. I don't have mufflers or caddy's ruins the hp I just change the settings with my laptop

How then does Ford make 435 HP out of a 5.0 Coyote with full emissions, catalytic converters and unleaded fuel?
See http://www.motortrend.com/cars/ford/mustang/2017/ for proof that I am not wrong.
Could it be they know something that you don't?



"Why should I leave the smog equipment on if I live in an area that doesn't do smog inspections?"
What's good sauce for the goose is good sauce for the gander. I lived in Florida and had two smog pumps fail on two different 89 5.0 Mustangs. I replaced both of them, even though there was no emissions inspection. Why?

1.) It a federal law that requires emissions equipment to be in place and functional. I have no intention of breaking a law designed to protect my general health and wellbeing, even if I don't like it. I have respect for the rights and wellbeing of other people, and am not one of those whose nature is rebellion.

2.) Whatever imaginary "improvements" someone may strive for, there is very little evidence that the results of removing emissions results in a better car. I can achieve excellent results in performance with all the smog equipment in place and working properly. Maybe you can't, but that is no excuse for removing the emissions equipment. Look at the new 5.0 Mustangs – 281 cubic inches and 435 flywheel HP with full emissions equipment with no aftermarket parts. That tells me that it is possible on a mass production car. It also shows that the guys that designed the engine knew what they were doing to achieve that goal.

3.) I like to breathe clean air, and working emissions equipment helps me do my part to make that possible. Los Angeles has breathable air even with millions of cars: Beijing, the capitol of China has some of the worst air in the world. Why – no emissions requirements for cars.

I don’t want to live where the air looks like this…
