[Shotimes] How to get 300HP from your 3.0L SHO engine

[Ron Porter]

Ah...that's the fly in the ointment....."without affecting the cars
usefulness as a daily driver"

If you do it n/a, it most definitely WILL affect the daily usefulness. Can't
get something for nothing, especially when you move the torque curve around
to favor high-rpm operation. This is one of the touchy problems with trying
to put stouter cams in a small displacement engine in a heavy car with no
gearing options.

IMHO, I don't view 300+ HP in this engine as big that tough to do, but it
would make more sense to put it in a sub-3,000  car with lower gearing.

OK this is always fun.  How much HP do we get from each mod in a 3.0L
engine? (This of course precludes adding displacement....:)

What so fun about this is that it quite easy to increase the HP of this
engine without affecting the cars usefulness as a daily driver and also
without taking an equity loan on your house. You can probably do the below
modifications for ~$5000 + labor.

The HP numbers below are estimated based on the assumption that all
modifications are initially installed in the car (thus producing 300HP).
Then I take one modification away and "estimate" the HP drop.

                                               Subtotal
Base setup:        220HP
                                                   220HP
Rotating mass (external):
UDP:                     5HP
8lbs flywheel          2HP
                                                   227HP
Exhaust:
HiFlow Y-pipe:       10HP
2 1/2" catback:        5HP
                                                   242HP
Intake:
77mmMAF + CAI +
69mmTB:              12HP            
BBB + EH +
porting:                 15HP
+20 CAMs:           15HP
                                                   284HP
Electronics:
WideBand HEGO +
Tweecer:               15HP
                                                   299HP
Lubrication:
Amsoil 5W30:         1HP
                                                   300HP

There are other things one can do, but that will affect the usability of the
car as a family sedan, namely:

Intake:
+40 CAMs            10HP (assuming a +20 base)

Rotating mass (internal):
Forged crank +
rods + pistons:     10HP
                                                   320HP

For a grand total of 320HP.

And there are probably other tricks too, such as flipping the [forged]
pistons 180deg, lowering friction of all turning parts by properly coating
them, etc.

What do you think the HP numbers should be???
