As some may know I recently put Explorer manifolds on my car along with the bigger MAF and thottle body. I recently got the car dynoed to see what improvment there was.
Here are the Printouts.
Power and torque curves.
This has the air fuel ratio of the latest run. The first run didnt get this hence the dead flat line.
Previously the car did 136 on a 10 degree day then a 131 on a 20 degree day. The lower run is the 131. I asked for the lower run to be included as the higher run was done on Saturday and was arounf the 26 - 27 degree mark.
The car is as follows.
EBII, stock snorkle, AU maf body with the stock EB electronics, AU throttle body and EGR plate (egr blanked off with the stock system unplugged), explorer upper and lower manifolds, stock 19# injectors, fuel pressure of 285kpa, stock exhaust with gutted cats. ECU is the stock auto unit. Transmission is a T5 with a 3.45 diff ratio.
I am a little unsure of the a/f readings. On the graph what is lean and what is rich. The guy mentioned that it was running slightly lean in the top end but wasn't anything dangerous.
The car also has a bit of a running problem. In first it feels like it really struggles when I pin it in 1st gear. Its hard to describe but it doesn't feel like its making the power the way the graph depicts it. In 2nd its fine however and 2nd feels like it accelerates and pulls way harder than 1st. Wtf?! Off the line it feels really gutless to the point i really have to ride the clutch to get a good take off. To give you an idea an Stock NC auto with a 3.08 diff keeps up with me in 1st gear but when I get to 2nd I can walk away (slowely).
This problem started straight after I converted to manual (which is when the cats fell out) and is a bit more pronounced with the new intake.
ANY idea's/tips/theories are welcome for discussion!
