i want to convert my vette back to stock to see what kind of times it will run. in a post in the street racing board, someone was talking about a stock 5speed fox-body Mustang that was running 12s with just gears, converter, suspension upgrades, and slicks. i want to try that. anyway, what is the factory fuel pressure setting so i can set my adjustable unit to that? thanks in advance

 

43 PSI at idle with stock injectors.

 

38 at idle, 42-43 with the vacuum line removed

 

How can it be a "stock" car with gears, convertor, slicks and suspension mods. That does not sound very stock to me.

And those 5.0 mustangs like a lot more gear than our TPI cars do, I do not think you would get the same result with all that gear and convertor.

 

the engine was completely stock, right down to the paper filter. he modified the trans, suspention, and tires to see the real potential of the motor. and about the gears, my vette has the base 2.59s. i was planning on upping that to 3.45s. that should provide a pretty good increase in acceleration.
