Just had my engine dyno'd and air fuel ratio checked
4.2 block / 4.0 Head.
Results: 124.9 Horsepower. I should have about 160, yes?
Air/Fuel ratio came back a tad lean if anything.
Engine has about 60 miles on it.
Mechanic told me there's nothing wrong with the injectors.

Re: Just had my engine dyno'd and air fuel ratio checked
Is the horsepower that you are getting at the wheels, or at the crank?
What is the difference in the heads to create more horsepower, or have you
done some other things?
At what RPM was the highest horsepower created?
Just some questions because I'm looking into stroking my 4.0

Re: Just had my engine dyno'd and air fuel ratio checked
The 4.2/4.0 mod should add about 40 horse power due to the porting on the
4.0L head.
I'm not sure how the dyno test works but I think it's at the wheels.
Looks like they cut it off at about 3350 rpm.

Re: Just had my engine dyno'd and air fuel ratio checked
I was told there is about 30% loss on 4 wheel drive vehicles. The guy that
did my Cobra said, he had seen a 60% loss with some Audi all wheel drives.
Auto or manual makes a difference too.
In addition, 60 miles is not enough to let everything seat properly. I had
my Cobra tested at 2222 miles and was told that is still not enough miles
for proper seating.
What was the A/F ratio in numbers? I would think it needs to stay around 12.
