Default Would it hurt a tuned port injection engine to run race fuel

I have a 350 TPI in my truck and was wondering while I have it at the track messing around in it would it hurt to run some race fuel in it? Or should I just get some 93 octane at a regular gas station?

If it's basically stock run pump gas and save your money.

Should not hurt... don't expect any big improvements though. I have ran race fuel in my lawn mower when out of pump gas... put it in bikes too. No real notable benefits other than it may run slightly run cooler & possibly take away some ping depending on timing. In a stock motor, I agree w/ El`SUPA BEASTO~... it is a waste of money.

IDK just thought it might be good for it but I just put some 93 in it should last a while as much as I drive it LOL

112 is $8 a gallon here but shoot, go for it man, its only money!

On the plus side: You'll be able to run the timing up more and it smells damn good :wink:

I for the life of me don't understand why this happened...but it did. My uncle ran out of gas while mowing his yard with a JD riding mower...put in some race gas and the piston ended up melted. I do not understand why but it happened. :?

Well Burns, it is $9.25 in Oregon for 110. You would see more response & gain by advancing your timing than a few gallons of 110 JMO... Casey

Default Lead kills converters and O'2 sensors

The lead in the racing fuel WILL kill your O'2 sensor real fast, and your catalytic converter as well. Five gallons, if it were not diluted would be enough to do it. This will not set off a check engine light instantly, but will make it run too rich from that day on.......
The piston burned that was mentioned would have to have been on an engine that could not compensate fuel mixture for a very low specific gravity fuel that ran too lean compared to the heavy SG pump gas that has near .745 on no lead and .699 SG on C 14 racing fuel, big difference on jetting requirements, not the octane. I hope this answers your curiosity about leaded fuel in your emission engine.
