We did stage 3 N/A comps on a Coyote. It picked upp 30 rwhp at peak (447 to 477) and picked up rwtq from 412 to 420. They did lose under 4000 rpm though.

The best part about the cams is out at 7500 rpm. They were up 60 rwhp over the stockers. 467 rwhp vs. 407 rwhp.

Mods to the car before the cams were:
Longtubes
Off road pipe
Axle back
JLT intake
Ported stock intake
Alum driveshaft.


Ill get a dyno graph up for you guys.

And +1 on Shaun from AED!!!

quick compare of the stage 3 to stock coyote and the cobra jet cams.. those stage 3 cams are beasts.

coyote stock - best info I could find please fix if you know the exact values.
intake
12mm lift, 211 duration at 0.050" lift, 260 advertised
exhaust
11mm lift, 211 duration at 0.050" lift, 263 advertised

cobra jet - estimated based on what ford racing provides and stock coyote cams data.
intake
13mm lift, 213 duration at 0.050" lift, 263 advertised
exhaust
13mm lift, 232 duration at 0.050" lift, 290 advertised

stage 3 comps.- these require 20 degree limiters for piston to valve.
intake
12.5mm lift, 236 duration at 0.050" lift. 276 advertised.
exhaust
11.5mm lift, 239 duration at 0.050" lift. 283 advertised.

you can see that the comp stage 3 cams are oriented towards maximum rpm.. not sure if the reduced lift hurts anything with a 4 valve head. these are the NA cams not the blower cams.

edit - here I found there is one more even bigger cam from comp. its called the RACE1. (stage 4?)

14.5mm intake lift, 240 duration at 0.050" lift.
13.0mm exhaust lift, 242 duration at 0.050" lift.

I don't know why the skew the lift to the intake side except there may be a limit on the max lift of the coyote head architecture.
