So here's the rumors of the first numbers from the Trick Flow Intake...

Nice top end increase, would have like to see them go to 6250 and 6500. Most of the numbers in the chart workout. But 7 lbs of torque at 4000 RPM is 5.3 HP. So you cannot change torque by 7 lbs and have HP change be zero. It is not logical. :shrug:

Correct, HP is derived from TQ through math. I saw that also.

Also, Im a little lost by the 20hp at redline increase. Just doesnt seem right.
 
Update: my order from Summit:

A dyno graph would be nice. But based on the little we have to work with it looks like the stock intake manifold just does not flow the air needed at the higher RPM's. It would be interesting to see how well it works with ported heads.

I'm just stepping in to add something, note that I am really really bad at math so.. This is just talking about increases in trq and hp over the stock numbers right? There is actually hp there it's not at 0hp. I thought I had seen certain setups that can drop hp but increase trq, mainly in towing applications and such. So maybe it's just a change in the way the power is being made or something. Bah oh well I don't know if any of that made any sence at all.
