Getting a 5.0L into the coveted 12 sec e.t. is not as hard as it may seem. To attain sub-13 sec. e.t.s start with a 5-speed version of the 5.0L. Mix in a lightweight version (coupe), well thought out bolt-ons, traction e.g. slicks, and aggressive driving.
I have compiled a list based on facts, not generalizations and assumptions that has the potential to propel a stock long-blocked fox body into the 12's. A good tune is paramount in the quest to reach this goal.
- 26 x 8.5 x 15 slicks (can mount on turbines/10 holes and retain quad shock)
- 3.73, 4.10, 4.30 gear (select ratio depending upon tire height selection)
- Headers (long tubes>short tubes)
- Off road H or X (may need to replace to pass emissions test where applicable)
- Under-drive pulleys (may eliminate need for these if serpentine belt is eliminated, use caution if employing this mod and use at track only)
- Eliminate factory air silencer
- At a mininum use a K&N panel replacement filter
- Stock T.B. and M.A.F. will work. (track testing showed no loss of e.t. or gain in MPH when switching M.A.F. -same day testing-
- Remove front sway bar (helps with weight transfer)
- Remove stock clutch fan (*if* using underdrives)
- Short-belt (*if* underdrives are used)
- Advance timing (13-14 degrees is a good start)
- Adjustable fuel pressure regulator
- Remove unwanted weight ( you be the judge, what do you want to eliminate, *remember these small c.i.d. engines do not like to lug weight, removing approx. 100 lbs. of weight nets a mph increase)
- Practice, practice, and more practice. (If you are afraid to break something your leaving precious e.t. on the table)
Some additional mods to consider:
1. Synthetic lubricants throughout
2. Aftermarket rear control arms
3. Sub-frame connectors
4. Increasing air pressure in front tires to decrease rolling resistance
5. Aftermarket shifter
6. Battery relocated to rear of hatch/trunk
7. Air bag in passenger rear coil
8. Light weight wheels
9. Ice upper plenum (gains of 6-8 H.P. here -dyno tested-)
Mods that produce minimal gains if any:
1. off-the-shelf chips
2. aftermarket ignitions including expensive spark plugs
3. bigger injectors (contrary to popular belief upgrading injectors will *not* produce more power)
CAN WE MAKE THIS A STICKY?
