Ran VP racing fuel in MX bikes before. Just wondering if anyone has any experiences running it late model (street-legal) vehicles.

Of course, it's too expensive for daily drivers, but for the recreational weekend ride, it may be justified.

(look under the unleaded category)

all of my friends run race gas in their street cars at the track or on the street when racing. Most of them are '95+ model years. I've never heard any of them say bad things about it. Plus, it smells good! lol

I haven't had a chance to run it in my '05 yet because it's not here. lol.

 

I have, personally, never used it 'cause I had no need to, but I few of my buddies use it for "special occasions" and they have nothing but good reviews about it.

Their only complaint is that its not as available and not as cheap as 87.

 

hmm leaded gas

There's a gas station around here that sells it around $4-5 a gallon. I don't know if the 104 octane gas will buy you anything unless the car has been tuned. I don't know if leaded gas does damage to your engine either without modifications for it.

 

Why would you ? A street tuned car gets nothing out of race fuel .... If your car is not tuned for higher than 93, you are wasting your money ... You may even hinder performance ...

Race fuel <> going fast

 

In some cars wouldn't running an octane higher then what you engine is rated for would actually thrash various components in the car?

If you want performance gain you gotta mod the engine.

 

Anything is possible .....

 

Like I said, I gotta couple of buddies who like to for "special occasions". One in particular, Curtis, has got this "Dr. Frankenstein" of an engine builder that he uses on his '93 Shotgun Package LX he compete's 1/4 miles at a time.

 

the cars i see it running in have in dash electronic fuel control/setting systems. They have to tell it to switch to race gas setting. Of course putting it in a car that wasn't made to handle it wouldn't do anything.

 

supposing it made your car go 0-60 in 4 seconds; how do you get it? Authorized Dealer?

 

Unless the EEC will make significant changes in timing based on the fuel it detects, then a higher octane fuel is only going to cost horsepower -- it burns slower (that would be the point) which is not a good thing. Race fuel is for when you go to the track and want to turn up the boost, and you need the octane to prevent detonation.

You are correct. A coworker here races a Datsun. He uses racing fuel and I know his brand does contain tetraethyllead. The lead byproducts adsorb onto the surface of the platinum in the catalytic converter and will poison it. This destroys the greater part of the effectiveness of the emissions system. Aside from this and legal problems of running leaded gasoline on public roads, racing fuel is quite an excellent idea!

 

So what would the 'ideal' octane to be used in the 05 engines that would not require a tune?

 

I will be running C-16 in my '05 once the new motor is in it.
