The use of toulene should have NO effect on a wide band o2 sensor toulene is the #1 chemical used by o.e gas manufatures to boost oct. of fuel

There was a guy in the shop today that works with "ron" the turbo masarati guy, He did a test with toulene while working for ford & testing a turbo 6 they where workin on in the past.... He told me today that it should have no effect on 02 sensors and showed no effect on there testing.....as it has the same specific gravity as auto fuel......... But avgas would show a higher a/f than autogas as its lighter........

Luke

ever you told me the other day Larry that the specific gravities are different. I found an article of "tuning w/ toulene".

it's not the specific gravity that throws off the sensor, it's the water produced when toulene burns. (what I've read and been told)

Luke is your turbo a BB? When do you reach full boost?

Tim is it still possible to get lukes turbo

Toulene added in a small percentage shouldn't effect WB reading. I will check with my main source this weekend....a retired research chemist (my father).

If i'm right, I should see 320ish @ 18psi with a safe mixture

One of our customers just dynoed his 60-1 hi-fi BB with a true Garret hotside(the A.R and turbine trim will remain a secret though. ha, ha) and he made 354 or 359 ( I forget) at 13 psi, on a Dynojet. This was a 2.5L on pump gas and it had the stock chips in it too! He has most of the componenets we are using in the 420 power package. At 18 psi, it should make about 420 at the wheels on a 2.5L. We will find out soon enough. You dont need to run crazy boost and race gas to make power. I would like to eclipse the 400 horsepower at the wheels mark, with the least amount of boost possible, using pump gas and still retain the stock bottom-end doing it:^)

Uhhh, what's the byproducts of burning hydrocarbons???

Right. In the U.S. gasoline can have up to about 30% aromatic hydrocarbons (ring-shaped). This is primarily toluene and xylene. Germany can have up to 40% aromatics which would increase octane by about 5%. Race gas is composed primarily of octane-boosting aromatics like toluene and xylene. Yes, they have higher specific gravity, so you end up a little ricer when using such cocktails.

I was under the impression that Toul. and Xylene weighed less and therefor you had to squirt more. (same w/ av gas)
