Just bought Texas speed 2.5 5.3 L heads
What kind of power does everybody think Ill be making??
Ive got:
02 WS6 6spd
Torquer 2 232 234 114 .595/.598
True duals
LT's
LS6 intake
4:10s
PRC 2.5 5.3 L heads milled to 61cc
NGK plugs and MSD wires
30lb injectors
9 inch rear end.. Strange with moser axles.. spooled
Those are all my engine/powertrain mods.
What kind of power can I be expecting to put down. I have not gotten the car tuned yet, but it does not seem any faster then it was before I put the heads on.
I have been cam only the past few months, and I had a pretty damn good cam only tune.. Then 2 days ago I added heads and a nine inch.
Does tuning really make that much of a difference when adding heads? Because like I said the car doesnt feel that much faster then it did cam only.
I guess the 200 added pounds from the 9 inch over the 10 bolt could have a drastic difference as well.
Anybody think that a tune will help me ALOT?

Dont worry about dyno numbers. Dyno numbers should only be used as a source of reference (baseline before modding, air/fuel mixture, power curve,etc) I would imagine you would dyno around 425 rwhp since youre an M6. Add a 90/90 and youd probably see 440-450 rwhp. Maybe a tad lower thru the 9". Id port my throttle body too if I were you if you dont go with the 90/90 setup.
I just bought the same heads for my stalled auto. I was debating on the Torquer V2 cam, but I went a tad smaller with the 228r. Its a proven cam....runs strong and very streetable. You should be happy with that setup though.

When I swapped my ported stock heads for an aftermarket casting I picked 20 rwhp immediately and then another 20 after the tune was dialed in. Considering you added a 9 inch I think all is well.
