Can i run 110 Leaded Race gas in my 2008 turbo with aftermarket headers full race exhaust , tune and every bolt on they make for this car?

 

Sure, it's hard on cats so if you don't have them, should be okay. Also hard on o2 sensors but you're not running it all the time.

 

Thanks Brother!!

 

Like he said it will foul up the plugs , just make sure you run a full tank of regular gas right after

 

THANKS!. What is the highest octane fuel you recommend running on a regular basis?

 

you can run race gas all you want. i tried 110 leaded at the track once because it was cheaper than 100 unleaded just to see what happens and i dont like to do track events on pump and didnt notice a difference.. really unless your tune can take advantage of the 110 or you can get tuned for 110, I'd run 100. I've not ran anything below 100 oct for months.

 

You will do irreversible damage to your cats and O2 sensors. They may not die right away but it will definitely shorter their life. The lead in the gas poisons the catalytic reaction responsible for O2 sensor and catalytic functions. Once is is there it never goes away. It is good for valve seats though.

 

I don't have cats on my car. Headers to full race exhaust.

 

Even with no cats itll destroy your o2 sensors. What are you trying to achieve? There are a lot of high octane unleaded race fuels that wont cause these problems. You'll have to have the car retuned to take advantage of the octane anyways.

 

Unless you're tuned for it, doesn't really make any sense. But otherwise run it as much as your wallet allows.

 

The lowest octane fuel that you can run without detonation and having to pull back your timing will yield the most power. Think of as the octane number increases the burn rate slows.

 

Just run unleaded race gas. 110 won't help you any more than 100 or so unless you have a built out motor and crazy boost and all.

 

we used to do a "trick" of pulling the primary O2s out every couple of tanks of leaded fuel and run over them with a lighter for a few mins to "clean" the O2s. dyno shop owner/tuner suggested it to us- he said he had to do it for the wideband sensor that he used on his dyno to get AFR readings every so often after cars tuned with leaded gas to keep it from fouling out. not sure if it really helps but i have ran hundreds of gallons of leaded fuel in past car and never fouled out an O2. could be just lucky?

but again, unless you are tuned for 110, you don't need it.

 

On the plus side, I love the smell of 110 octane exhaust. Smells like POWER. I run it in a racing ATV I have.

 

I only have 91 in my area, but we have 110 and 100 leaded at the pump. My tuner said do not run leaded due to the 02s. I am tuned for 100, but the leaded trashing stuff is not worth it
