Hello, I am new to the 5.0 seen. I was a old Grand National owner and raced the Buicks since 1988. I loved those cars but I also always like the Mustang even though the buick guys and mustang guys did not get along.

Well now I have bought myself a 1987 Mustang GT with the following mods.

Brand new Eagle 347 Stroker with Mass air
AFR alumium Heads
Elderbrock upper and lower
42 lb injectors
70mm BBK throttle body
Long tube BBK headers
MSD TFI full ing.
vortech s-trim blower

hooked to a PA C-4 super comp trans with brake
alumium drive shaft
Built 8.8 with spool 3.73, moser axels, c clip elm.
Florida 5.0 dash...ect


Well my question is that this car has about 50 miles on it, eveything is brand new.

It has 6 passes on it with pump gas and has run 10:66@125 thru the exhaust on drag radials.

The car was Dyno tuned to be between street and strip, so it runs on pump gas only.

But there is no O2 sensors in it. How does this all work like this and is this a normal setup? what do I have???

 

sounds strange. i don't know how a mass air car would work with no o2 sensors..

 

um not to be mean but are u sure there is no 02's

and do u have a dyno sheet for the car?


nice numbers though..

 

worked in my mid-10 second Mustang, I was running 19#'s of Vortech T-Trim...Sounds like the O2's taken out with the tune...more of a problem on the newer OBD2 cars...

 

yes they told me it was dyno tuned and I have the dnyo sheet, I just didnt understand why no o2 sensors. I have never seen it done like this before.

 

What are the O2 sensors for?
