Didn't know if anyone had seen this yet? Searched the forum and didnt see anything .

thats pretty crazy..not that familiar with dynos...do you know what kind of they the 370 was on?

 

i read another thread about the 370 having 286WHP...something to do with different dynos having different numbers

 

i dont know what dyno they were on. but yea i have heard of different dynos having higher readings.

 

thats not a bad gain

It's not uncommon to see gains out of modern high performance engines when you put high octane gas in. You just arent supposed to use leaded race gas with exhaust catalysts. It will clog them up.

Unleaded 100 would have probably shown the same gains.

 

the track around here sells 110 octane gas...so i know that better fuel gives gains but i didnt know that it was that big of a difference

 

wow, nice find!

 

Guys, guys, highly oxygenated race gas is not the same as high octane gas. Highly oxygenated gas produces more power because it supplies its own oxygen molecules for combustion. This means that the same amount of air that you'd add certain amount of normal gas, you can add a ton more oxygenate gas. The more gas you can burn in a cycle, the more energy you can produce. Nitromethane is a an example of that:

http://en.wikipedia.org/wiki/Nitromethane

Adding high octane gas alone without adjusting fueling and timing will yield no gains provided the car was not experiencing significant octane limitation before. Technically, most if not all cars should see power gains from highly oxygenated gas provided the fueling system can deliver enough fuel to achieve target AFR.

 

There we go...

 

I think they might be running the dyno on dynodynamics

 

before you fill up with that, make sure its unleaded if you have cats. most, if not all 110 octane fuels are leaded

 

man i want a 370!

 

dumb question but ill ask anyway, so if u have test pipes you dont have to worry about leaded vs unleaded?

 

Sounds like "bovine scatology" to me.

 

Leaded fouls O2 sensors also.

 

I always fill up at the dragstrip.

 

Correct.

 

Lead fouls O2 sensors also. They coat the sensor.

 

yep. id say keep a spare set of 02's to run on race gas.
