before my HO conversion the car would chirp when I would floor it from a stop. Now after my HO conversion which was supposed to ADD torque, it won't chirp. Whats going on? Is the mustang cam that upper end? What are your guys experiences. Maybe I need 3.55 or 3.73?

If your car chirped before it was a freak of nature.

Mine would spin a tiny bit with the CFI. But now I have bogging problems from a stop with the carb and cam. :

Do you have a HO governor in the trans? If not you are shifting way to early, way before the torque/HP peak. Shift it manually and it might.Builder/Owner of Badass Panther Wagons

He is saying that from a dead stop if he puched it it would chirp. This is not something a factory panther car can normaly do.Comment

I got the govenor, but I'm talking about from a stop. If I didnt have my high rpm power loss I could really chirp em on the 1-2 shift tho.

yup my 89 lopo with single exhaust would chirp it if the AC was off and no one was in the car but me, from a dead stop. the chirp would only last about 1 second though.1989 Lincoln Town Car - "Anabelle" - Original block, .030 over with SpeedPro pistons, rods fitted with ARP hardware, FRPP +volume oil pump, GT-40 3bar heads, Crane 1.72 rockers, 89' Fox cam, 93' Cobra lower intake, Explorer upper and 65mm TB, 93' Lightning EGR spacer, K&N intake kit from a 4.0L Ranger, 19lb/hr injectors w/ 87 Mark VII ECM, cat/smog deletes, Big Brake conversion, 3.55 K-Code Trac-Lok/Disc brake rear axle, CVPI LCA's w/1" sway bar in rear, wagon front sway bar, BBK 2.5" off-road H-Pipe, Flowmaster super 40s, HPP wheels, 3G alternator w/LMR.com wiring kit, gear reduction starter conversion, Best 1/4 time: 16.0 @ 85mph.Comment

My tired 167,000 mile 1989 Crown Vic would spin its one tire and my 1989 72,000 mile Grand Marquis will spin both tires from a stop - for about a second. I think that's normal - depending on the quality of your tires, I suppose . . . .
Remember, when the convertor stator isn't turning, the torque multiplication is at its highest. If what TCI information says is accurate, the torque multiplication for a stock converter can be about 2.5! So, with our stock engines, with torque maxing out at a low 2000 to 2400 RPM, we can send over 500 ft-lb or torque to the rear wheels - that is, until the stator starts turning - that's why we can "chirp" them tires - if only for a second.

The main reason isn't the opened up exhaust, it's the HO. The torque peak is higher than a lopo.Builder/Owner of Badass Panther Wagons
