I see a lot of big whp #'s being put down with the stock IX turbo, mostly on race gas or very high octane gas. Do you people just fill your tank for single a dyno session or do you guys actually run this stuff on a regular basis. I'm talking about 104+octane or race gas. My car puts down 310whp and 325ft-lb all day long on 93 octane. I'm curious to see what it would put down on 104+ or race gas, but I could never afford to run that stuff on a daily basis.

 

most people use race fuel for just that purpose...racing. Go to the track (drag or circuit) and get the most out of your car. It's just not economical to run a fuel that costs much more then a 93 octane out of the pump.

However there are those people that don't daily drive their cars and only run race fuel when they take the car out for a joyride.

And there are those sick bastards who drive their cars only on a diet of race fuel and they use that car as a daily driver... Hey if I had the money to do it I know I would be one of these people!

 

It's obviously not economical, but I still see a lot of people tuned on high octane gas and race gas. Do people actually put down that much power on a daily basis or is it just a temporary tune to see what the car puts down on the dyno?

 

they probably have a stand alone to switch maps

 

310/235??? Something is wrong there.....

 

That was a typo. 310/325.

 

the OP switched the numbers. Look at his sig.

 

To clear things up.

 

Does E85 count?

 

i run race gas about 4 times a month...weekend track days...i usally mix 2 gallons on 93 octane and 3 gallons of c16

 

I have two different maps. I use my cable and laptop to switch them out. Ill run a 2 or 3 runs looking for knock

 

Yes, you did. You wrote:

Someone questioned it, and you still didn't notice.

Standalone?? You mean they have the stock ECU and use EcuFlash to quickly and easily load separate maps depending on what fuel they're using at any given time.

OP, I run e-85 all day long everyday, and it costs less than 85oct by over a dollar. It's better than high octane race gas and is environmentally friendly, though not a long-term alternative for oil unfortunately (not yet anyway).

 

IF you buy it from a pump I am pretty sure it is pump fuel, it is less than racegas, and it makes mad powa...

However since you asked about gasoline and specifically 92 with a IX turbo, here is the result of one of our customers on the same type of dyno that you were on:

351/340 were his actual numbers on the dyno dynamics with S2s and 24ish psi from a IX turbo on his VIII

 

Nice! Way more than I make! He better bust out some 11.4s!

 

I am hoping...it would make our day and his I am sure.
