Let me tell you guys about my car:
1986 mustang gt 5 speed, 5.0 HO engine.
mods:
STOCK ENGINE, intake, injectors (19's pounds), stock heads, stock computer.
BBK equal lenght headers into 2 1/2 exhaust, NO CATS, flowmasters 2 chamber.
3.55 gears, centerforce cluth, T5 with world class kit. M6L ignition, 2F blaster coil, sunpro boost guage, autometer electrical fuel pressure gauge, autometer pyrometer.
P600B, 2 core intercooler, ATI FMU, aTI 255 LPH in line fuel pump.
i am running the stock 8 rin crankshaft pulley with the 2.70 inches blower pulley.
I see about 10 pounds of boost at 5,200 rpm.
My car has the stock speed density system, with the check valve on the MAP sensor to eliminate the boost pressure to the MAP.
Still I feel the car strong, but not all times, sometimes I press the pedal to the floor and the engine would rev up very slow with no power, still I see bost but not that much, no black smoke from the back, so Guess I dont have a rich condition, I also have low exhasut temperature less than 1200 F degrees so I guess no lean condition either.
My best guess are:
1) I did not calibrated my plugs lower than manufacturer specs, so it might be posible the boost is making the sprak go off, but still I dont feel like a missfire on my engine.
2) I need to change my speed density to mass air flow system, maybe A9L or A9P computer, 30 pounds injectors and calibrated 70 mm mass istr flow sensor, along with trick flow intake and 70 mm throttle body.
So that is my story, I really need the help guys, all sugestions are very welcome.
Thanks.
Pablo
PS: By the way, those p600 sure make a lot of noise at idle, they sound like a bad steering pump, but when you rev it up ...ahh that sweet whistle.
