ok its close but i have questions and yes i searched.

[boostedbruiser]

Well i'll try things one at a time till i get it right.
i think i have the timing at 8 9 degrees. i have the knock sensor plugged in but man does the computer pull back the timing. you feel the difference.

i don't know mucha bout the turbo as its not the stock one, but i do know it has a 50 AR? its stamped on the turbo housing.

I have a spearco FMIC to get instaled, i just need some cash and time.

for now i'll just drive it on the safe side at 15 PSI .

maybe the turbo is too small and is over worked. Heck who knows.

If i was to adjust cam timing which way should i go adavned? or retard?
oh the cam is a A237

Be careful when handling / pouring Toulene. It is absorbed through the skin and will damage your kidneys and your liver. I worked with it for years in the family business. It was a contributing factor in my oldest brother's kidney failure. He is now on his second kidney transplant. I'M NOT JOKING!

The best thing that I can say about any local pump gas lately, is just don't trust it. Last year when I went back East and down South for the Reunion, the 89 Octace was better than the 92 out here. Now things are different. The Hurricanes have brought the supply chain into play, and I believe that any underground storage has taken precedence over which reservoir it gets pumped into. In other words, expect the lowest octane despite what you paid.

Ill second that. Ive been getting all kind of knock in my other turbo car...a/b 4* retard @ 15lbs w/allky. I was running 21lbs and aklky with 7* retard. Im sorry but thats nothing but bad gas(or low octane). I dont mind paying for gas but I want what I paid for.

I guess its time to add some toulene to the gas....... is that the stuff?

Ooh, previous owner work... that makes me suspicious. There have been more than a few POs that either put flattop pistons or closed chamber heads in without telling the new owner.

Without checking i can't tell you about the head or pistons. i did only get about 160 psi across all 4 cyl on the compression check and i'm running a A237 cam straight up

How did you check the VAM?

Seriuosly. Try a different VAM. I had the exact same problem as you and did everything that ws recomended.No fault's, motorcraft secondary ignition, octane boost, EVERYTHING.

Try a different VAM and watch your wideband to see if the A/F is still acting the same.

It may sound crazy but I couldnt find anything wrong with my original VAM except that it had been apart at one time. Tossed the new one on voila. No more detonation at over 15psi.

i guess its worth a shot. although i did test it with a anolog meter and it had no dead spots. As far as electrical it tested as it should.

Dead spot or not, it may not be sending the correct voltage to the computer when running, and hence the computer may not schedule fuel correctly (pulse) to the injectors.....hence leaning out.

Below is a thread about how to check it. If you have done this, then good. Did you check the ACT ohms on the VAF meter leads too? That can have an effect on fuel scheduling as well.

Another thing. As for Toluene, DO NOT blend with gas above a 30% ratio.

Just for a little Monday morning "Mr Wizard" fun, the way to calculate the outcome of your octane rating is as follows:

(gallons of fuel X pump gas octane rating) + (gallons of Toluene X 114)

divide that by total gallons of gas and toluene combined

Example:
Say I have 10 gallons of 93 octane fuel. I add 2 gallons of Toluene. I will then have 12 gallons of combined liquids.

(10 x 93) + (2 x 114) = 1158

1158 divided by 12 = 96.5 octane

Kool info......Thx Kurt! But this only applies if you know for sure the grade of gas they are selling you in the first place? Even my patrol car as been running like crap the last couple of days.

Unfortunately, yes.

Like Pat said, and what you experienced at the reunion, you have to look at that number on the pump and just hope it really is up to snuff as to if it is really the octane they are advertising.

Even if the 93 pump were to actually be puking out 91 octane, with the above equation, you would still have 94.8 octane.

Good point. Atleast now I'll know better where Im at insyead of just usibg the "swag" method. Thx again Bro!

here's a good article on this

[boostedbruiser]

Thats a good article. Maybe i should of tried about 3 gallons of toulene in the car before i pulled the head(or blew the turbo). I bet with 20 psi, 9.5 compression, my car would've scream!. Of course given the pistons quaility, it might have been the only time it screamed lol.
