I've been looking at what gains I can get with some bolt ons, here's what I'm getting. Do these sound right?

- C&L CAI w/ SCT X-CAL 2 tuned by Brenspeed - ~20hp / ?? ft. lb. torque
- MRT Aero Turbine Axle-back exhaust - ~10hp / ?? torque (anyone have a number?)
- Screamin' Deamon Coil + Livewires - 14.3hp / 12.2 ft.lb. torque (claims MM&FF)

the numbers I'm coming up with is ~244hp and ~272 ft. lb. torque (if the hp and torque gains are the same)

Do these sound right?

Is there anything else that I can do that can give me more torque besides f/i?

you are starting at around 170 stock so with those mods 205-215 is a better guess...mods dont necessarily add on top like that either....so results may vary

The Potato

Ah, I see. I started with 180 hp and 210 torque stock also.

MrSandman

i've seen stock 4.0s dyno at 180..so who knows.

14.3 hp from ignition cables!? some one has been having a little too much happy smoke

Never believe advertising claims! especially coil and spark plug wires.

Sounds about right, except the coil pack and wires, probably more like 5hp to the crank. If you are talking crank numbers, then yeah, 260hp is reasonable. Which issue did you see the Screamin Demon coil pack tested? If you saw the packs for the GT, you are off a lot, the GTs get a lot of power from the packs.

V6 Spark plugs + Screamin' Deamon for 3.8 and 4.0 Mustangs, found in the March issue of MM&FF

I still think those numbers are a little high but the gains are possible. The only way to know that is to get it dyno'ed to see what your numbers are before and after the modifications. JMO J

The Potato

any other mods that I should do for power besides f/i?
