Need a HP guesstimation
Just wondering what a 2004 3.9L would put down whp wise (only want a rough guess) with:
CAI
Pulley
Shorty headers
Tune
True duel
Flowmaster 40
8.8 rear with 3.73's
65mm TB
224 .55/.55 1.7 cam
the usual bolt on goodies

I agree, the cam with little to no head work won't do much.
On heart breaker dynos split ports put down between 155-170 rwhp depending on the tranny and outdoor conditions.
CAI - 3 rwhp
Exhaust - 5 rwhp
Pullies - 4 rwhp
Tune - 5 rwhp
Cam - 10-15 rwhp
That's a total of 27-32 rwhp over stock. Keep in mind people with stage 2 ssm kits only put down 190-210 rwhp.
