From ZZP valued at $130. Since I have 110 octane near my house can I play around with pulley sizes just for the heck of it? How much 110 should I put in to run say a 3.2" pulley for a couple of miles?

That depends on how much gas is in your car. Run it pretty low, almost empty and put in like 3 gallons or so, that should help out a bit, just make sure you change that pulley back after you have your fun...You don't need a new engine anytime soon.

might wanna see if that 110 is unleaded

There is no such thing as 110 octane unleaded (which you probably know), so its obviously leaded. But a couple gallons shouldn't hurt the 02 sensor(*) much.

Shawn

One gallon of leaded 110 can destroy your cat. Is it worth it?

Find unleaded. And when you ask if it is or isn't, get a second opinion or read the label before pumping.

Did a 3.2 come with the MPS?

Oh yeah...I forget about cats...haven't had one of those on a car for a while now... Now that Bill mentions that its probably not a good idea to run that 110 if you still have a cat. Try finding some 104 unleaded. Anything over 104 ISN'T unleaded, but just because its under 104 doesn't mean it is unleaded either.

Shawn

Actually......the 110 by fantastic and I'* house is unleaded.....Run it quite a few times in the bonne. So I guess in the end....I beg to differ? hehe

BTW- Congrats on the MPS Prescott!

You can beg to differ all you want, but there is no 110 unleaded, it doesn't exist. It IS leaded. It might not mess up your 02 sensors and cat a noticable amount at first but it is ruining them.

Here is VP Racing Fuels site...the highest unleaded they have is 105:

Here is Sunoco'* site...the highest they have is 104:

I don't know of any more sources to find info at, but nobody makes 110 unleaded.

None of our fuel comes from those places...
