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???
