Lead deposits

Post by BBO Omega »

Do you folks running leaded fuel notice deposits in your Intake Ports and Combustion Chambers?

I have been running Sunoco 110 Leaded fuel exclusively and the car sees as much sitting in traffic as anything with occasional blasts down the track.

Why are you running leaded fuel on street car. Please clarify? Maybe there are alternatives?

468 Big Block Olds with 11.59cr , 215 cranking. I can drive on 93 if I baby it. I’m not very good at that. Plus I occasionally turn on the Nitrous for additional fun.

I usually stick to something water based, leaded fuel burns after awhile. \:D/

And now I can't edit the dam thing. I should proof read before posting.

Have you done a dynamic compression calculation? How much nitrous do you hit it with?

I use leaded racing fuel in my race bikes....What left over gets used in my newer street bikes, usually blended with non ethanol pump gas...The VP fuel gives off a distinctive odor from the exhaust and colors the pipe interiors a nice light gray...The bikes get about 40-45 mpg riding in a sporting manner...I would hate to pay for leaded fuel in a high HP car...

$7.99 a gallon does get a bit pricey. I only spray 150hp when I do.

That's a good candidate for 100 ll AV gas. $ 4.30 a gallon at my local airport.
