Ever Put 100LL in Your Car?

Have you ever put 100LL in your car?

Yup. I raced with 100LL for years. Main reason was that I felt I was getting better fuel quality control. Another nice benefit is that it evaporates completely, leaving no oily residue. This is handy when using it as a cleaning fluid. For example, if someone were foolish enough to soak some Oil-Dri with 100LL and brush it back and forth over oil stains on a concrete floor, that someone would end up with a nice clean floor.

I also have the tank of my seldom-used home standby generator filled with 100LL on the theory that it is formulated to be stored longer than standard pump gas.

Great stuff, that 100LL.

:yes::yes::thumbsup:
Any motor I have that is not late model emissions equipted gets 100LL for long term storage.... From 10 HP generators to 600HP snowblowers...
 
!??! You race snowblowers?

Holy crap! That is quite a snowblower. Well, as I often tell my wife, anything worth doing is worth overdoing!
 
Back in the 80's I had a fellow classmate of mine put 100LL in his Ford Fiesta. He was bragging about how much extra power he got out of it... I can't say I saw it one way or another. Of course being 16/17yrs old at the time I'm not sure how long our cars lasted then anyway - with or without 100LL. :D
 

I will race him.....:D


79 Bronco with a 351 under the hood,,, 8' modified double auger snowblower driven by hydraulics.... 110 GPM @ 3200 PSI... Motor in the back just runs the Hydraulic pump... 510 Cu In bored and stroked Big Block Chevy.. Air research TO4B turbo... 16 PSI of boost ( that's 62 inches of manifold pressure for you aviation guys).. 620 HP... Notice there is no wastegate, I drive with the throttle to limit boost... MSD 6BTM Ignition... Throws snow from here in Jackson Hole, all the way to Nebraska...:D:D

It would be a silly thing to do, considering how much more expensive av fuel is but I'm wondering if anyone's tried it. If you have, did you actually hear knocking?

Sure - in my pre-emissions vintage Jaguar. Never very much, though, so there was no apparent difference. I have always saved my sump check fuel - and used it in my motorcycle and lawnmower. No ill effects noted.

I knew a mechanic who used drained fuel from tanks to put in his vehicle. It lasted a bit, but it died a quick death.
 
When I ran Dwarf Cars I ran it all of the time.

Now, in California it's illeagle to run on the public roads. I know a guy who has a friend who's brother's uncle's friend may run it from time to time in his Chevy LUV with a 406 small block that runs 14:1 CP. I was told it was in a pinch when he couldn't get VP C15 fuel.

You wouldn't happen to have a pic of this "Friends, brothers uncle's friends" Luv truck, do ya...;);););)
 
Impressive, Ben, but is a high-revving turbocharged gasoline engine really the best thing for powering a hydraulic pump? Why not a diesel instead?

It really isn't high revving at all.. I sized the turbo to get 16PSI below 3000 rpms.... Massive torque...


Diesel weighs too much for the back of a Bronco... I did do a similar set up ( Binford 10,000 snow removal system II) using a short bed Dodge ram pick up and a 5.9 Diesel motor in that one... It worked Great...
 
amateur hour. If your snowblower isn't at least 2000hp you aren't even trying. My former boss built this one.

Yes, I put 100LL in a 1971 Chev Impala. It ran GREAT. I don't remember if it had a Catalytic Converter or not. Probably didn't. That was a long time ago.

It would not have, they came into use in 1975-1976.

Back when I was racing Formula Fords, my engine builder, Steve Knapp, used it when doing dyno testing. There is racing gas that will give you slightly (1-2%) more power than avgas, so that's what we raced with.

I ran a little bit in my motorcycle, mostly what came out of the sump if it was clean. There was no difference in the way it behaved.
 
When planes have to be de-fueled at the airport most owners don't want it put back in the plane. Since VP C15 is costly "some" people may take it home and run it through a filter to use in their hot rods. There may or may not be several empty VP can siting around to help with the de-fueling process.
 
any time i have to drain a tank, it goes into my 68 vette. it was designed to run on higher octane leaded fuel and runs a lot better on 100 LL.

Not so much the catalytic converter but you'd kill the oxygen sensor and the car wouldn't run well with that fouled.

If you've been around small town airports where there was a substantial off-road or racing community around Friday evenings you'd see guys showing up with their fuel jugs to get some 100LL for racing.
 
When it was cheaper I'd run about every third tank-up in my Austin Healey. The last tank-up of the fall season would get a fill, two days before the first snow storm, and the Healey would go into my hangar until late April or early May.

Yes, and there were those who were thinking, "What's that idiot doing in the middle of the Beechwood Street intersection, taking pictures?" (Waiting for the the light to change so as to get unobstructed view of the Anderson Block and my car.)

Cool car, can I borrow it?
 
A few years ago I did a job up in NH and flew to Nashua, filled tanks, then rented a car and came back a week later when the job was done. One tank was down quite a bit, I was crawling over that plane like crazy looking for a leak. Then the line guy says, "Don't look too hard for a leak, that tank just took exactly 5 gallons." In other words somebody helped themselves to 5g of avgas, I assume for racing fuel! So yeah I think racers use it.
 
Not saying I do it, but our 1971 Dodge 383 Magnum loves it. ;)

So does the Jag XJS.

In the pre specialist race fuel days we used to use it in our race cars all the time in fact we had them set up so we couldn't use any less octane.

I used to put the odd few gallons of left over Avgas in my road going 2.0 VW Golf GTi ....it really gave it some get up and go !
 
I am not a Mopar guy but that is a great looking car. Damn, we have some motor heads around this place.

I am trying to find a way to install my power glide with a Trans brake in my 172. Am I over thinking it?
 
Works great in an old Karman Ghia. Every week the fuel delivery guy would drain about 5 gallons from the truck into an old bucket and into the ol' VW it went. Nary a problem at all.
