VP110 Leaded Fuel
 

Has anyone used the VP110 leaded fuel? how was it?

I want to use a high octane fuel for high boost (track car), but don't want the hassle of hauling 20gallons+ of E85 for each weekend.

VP 110 leaded is availalbe at most race track gas station around here.

Some people think VP110 is not suitable for a turbo charged engine, as it was designed for a high comp na engine.

just wondering if anyone has first hand tuning experience with this fuel.

"Not suitable" for forced induction compared to what though?

Q16?

VP100?

91 pump?

-edit- oh, you are comparing to E85?

So much more consistent and less hassle than E85.

right, that's exactly why i want to go with the VP110 leaded that's available at both buttonwillow and willow springs, and usually fontana too.

not a big fan of hauling gas on the road lol...

..ahem..FIXED..lol~!

Why don't you just ask the tech people at VP racing fuel?

I did, they were very responsive, but they said it was fine to use leaded and it won't have rusting issues.
i asked Sonoco too, and they said the same thing.

but i know from 2 very reliable source that using leaded fuel rust in their engine (after sitting for a short while)
one was in a rotary engine, and he was using C16.
which is also a non oxygenated fuel, but i did some digging, and it appears C16 is more corrosive than VP110.

VP110 will leave rust like deposits on your spark plugs.

Other than that I have found my engine looked great when taken apart after running VP110 and then sitting outside a couple years in the car.

Actually, that is not 100% true. I had one plate lapped and WPC treated (as an experiment) and the rest were new or used stock nitrided. The lapped plate did have surface rust in the exhaust stroke area.

Don't lap.

lapping is fapping.

I use VP MS109 and it is great. But race fuel should never be left to sit in your gas tank or fuel system for long, it also says that on the VP fuel drums.

Thanks Ian ! nice to have first hand experience =)
