You'll have to let us know how it works out!

OK so here is my report.

I am on my 4th can of it and have racked up around 400 miles on my car since I started using it. I am mixing it at 8 gallons per can (32oz) so 4 ounces per gallon. I have noticed that my car starts and sounds great. Very crisp throttle responce from idle. I have had no issues with pinging under load or power loss at temperature and I have tried my best to torture test it including racing it and getting an unfortunate *** kicking from a Camaro with turbos.......man that car was fast.

It smells like race gas thats for sure and it works and is super convenient.

I say 2 thumbs up and a right foot down!:D

This is good news! Could you give the details on your motor? CR, cam and whether or not it has much overlap, heads, etc. Don't be kicking yourself for getting put down by a forced induction car. I don't expect to beat any forced induction V8 car period and I feel like I have a fairly solid motor. But forced induction is a whole different beast. If I can somewhat hang with them, I'd be happy with that!
 
I'm not bummed about losing a race as my car in not a race car per say.

Those turbos spool up when there in the upper RPM's thats for sure. He sounded more like a jet than a car and I was surprised to hear his "jet engine" over my open piped big block as mine sounds like a funny car when its wide open.

Engine info is as follows.

500ci - Built by Kenny Hensley
11.75:1
Custom ported Edelbrock AL heads 84cc
Comp Cam custom grind solid roller cam .576/.582 lift
286/292 duration at .015 lift
248/254 duration at .050
Mighty Demon 825
Performer RPM intake
Bore 4.375
Stroke 4.150
Everything blueprinted and balanced and port matched.

There is 4 pages of info on my engine from the builder but I think this info should due for whatever you need.

So you know, Kenny is the builder and he is the one who implored that I run this thing on at least 100 octane. I tried during an emergency to get by on 92 pump gas and everything seemed cool till i went up a decent size hill and loaded the engine.....not good. I hate the sound of pinging.

When I started my build my intention was to build a street/strip car. Unfortunatly or fortunately I waivered from my original plan and built more of a G-car than a drag car.

No worries though. This motor is awesome and doesn't care if I race it or cruise it. It's a happy motor as long as I feed it good fuel.
 
That motor sounds like a beast no doubt and I haven't even heard it yet! But that gives me a good feel on how well the race gas is working. I'm going to run 91 with 28-30 degrees total timing but when I go race and set it closer to 36 degrees, I'm going to need 100+ octane.
 
I'm curious how they found the commercially available stuff was not consistent. They'd have to have various batches tested - seems rather expensive. I run VP when i need a special fuel. Never had an issue with it. I know there are plenty of issues with pump fuel but that's passed through a bunch of distributors and mixers before it's dumped in the ground.

If your really curious just call them and ask. They are real nice guys that have lots on knowledge on the subject.

Talk to Dan or Mark.

I have my timing backed off to about 29 degrees right now and my carb has been re-jetted and the PV changed on the primary side for ease of driving on the streets. I decided to set it up for cruising and better gas mileage. Don't get me wrong...it will melt the hides with a simple stab of the foot but tires are $$$$ so I try to stay out of it.

My advise is to not take my advise and call the Race-gas guys yourself if your really interested.
 
Try 100 L/L av gas, if that still isn't enough, add a little MMT with Lucas, Amsoil octane boosters or Torco Accelerator and read plugs closely, they'll get brick red if you add too much.

500 cubes with an 825cfm carb seems awful small. S/F....Ken M
 
I ran the AV gas for a few years and still use it occasionally as there is a small airport 5 blocks from my house. Roosterville Airport.

Works great as you say and I have no problems using it. I mix it about 50/50 with 93 octane BP and I have never had an issue.

The purpose and reason to use the Race Gas is to be portable so you can go anywhere without worrying about running out of fuel. We like to do long cruises to smaller towns/shows around here and most of the time its 100 miles + each way. I hate to say it but that's a tankful and some for me so I carry a can of this stuff and I'm covered.

I don't know why you would think that 825 cfm is small the way it's prepped. It's perfect. This engine has about 5K on it all street driving and lots of tire melting 3 gear burnouts. Plugs are perfect and it pulls clean and crisp all the way through the band. It's set up right for what it's used for. AS I mentioned above it's actually jetted down on the primaries one size and the power valve was swapped from a 5 to 3.5 to handle the lower vacuum signal at loping idle.
 
That's cool, I was just guessing based on past engines. I usually look for vacuum reading at WOT to see if it wants more carb; on a street driven vehicle, sounds like you're doing good.

The concept for the fuel for the road makes a lot of sense. S/F....Ken M
 
Exactly.

Were going to a cruise tonight that will be about 100 miles round trip. I can make that on a full tank of AVGAS and 93 octane pump fuel mix but I have the race gas mix in the trunk in case we decide to go cruise after the cruise. :D

I cant tell you how much this has improved my ability to be free to go wherever I want in my car now. No more calculating mileage or panicking cause the fuel gauge says E. :cheers:
