Timed with aDyno app on a mytouch phone...

1991 Mustang Convertible 2.3/AT, 215/70-14 tires on stock polycast steel wheels

1. intake resonator gutted
2. maf screen removed
3. intake hot air tube disabled
4. air box intake tube altered to improve flow
5. a/c belt rerouted to 87-90 style (smaller belt, no longer on crank)

Don't laugh, I know it's slow. Next step is to see if the udp is going to liven it up...

zonker

well i found out why it's soo slow...

the timing belt was 1 tooth retarded. GRRRR

i've got the new belt and adjustable cam gear on it's way, and then i'll start over.

zonker

got impatient and just relocated the cam gear on the existing belt. car slowed down... GRRRR

i heard that they like the cam timing retarded but one full tooth?? now thats one MILD factory cam if it likes that much retard.

sleeper_inc

1 tooth is equal to 11* retard/advance cam timing. The turbo cars like 4* retarded but I never heard the N/A's like it... hmmm gunna have to read up on it

zonker

38 teeth on the cam gear, right?
360 degrees (full circle) / 38 = 9.47 degrees (Lets round it up to 9 1/2).

zonker

OK, adjustable cam gear and new timing belt are installed and just did lots of runs...

Best cam gear setting seems to be -2 degrees. I finally broke into 19's in the 1/4 mile... Woo Hoo ... Haha

New run with new parts!

My exhaust manifold was cracked and my cats were blown out so I added a Ranger header, 2 1/4" pipe with a Mustang 5.0 cat between it and the flowmaster that was already on the car.

The car got loud... too loud for my tastes so i'm planning on a muffler and tailpipe change.

The exhaust changes seemed to help low rpm torque but made things softer on the top end (hp), notice the slower 1/4 mile trap speed and the slower 0-80 than before the exhaust change... go figure.

1. intake resonator replaced with 2.75" aluminum tube
2. maf screen removed

6. trunk gutted (-50 lbs)
7. Accel hi flow drop in filter element
8. Esslinger Cam Gear (set at -2 degrees)

10. 1988 T-Bird Turbo Cpe W/P Pulley
11. 63mm Alternator Pulley

13. 2.25" headpipe and CARB approved Mustang 5.0 cat. (one less cat and lighter tubing, -10lbs)
