I don't really care about how much HP, but am looking for your powerband. Please list any applicable mods (cam, heads, headers etc) and where you are hitting peak HP. I realize there are going to be differences based on the mod level but it would be interesting to see the powerband. If you have your dyno sheet that would be great as well.

ok it was fun but time to quite taking a dump in my thread. and that goes for me too.

On topic, the couple of posted dyno results I've seen all have tq max at 3000-4000 and HP from 5200-5800 rpm. Mods not available.

With that graph, I hope you're running 3.69's or better in the trans!

Edit:
Did some quick calculations, and you need more like a 4 series gear to take advantage.
With 3.69's
1st shifting at 6604 @ 45 mph
2nd starts at 3544 rpms (graph doesn't go that low, but around 150hp) shift at 6300 (80mph_
3rd starts at 4019 rpms (170ish hp) probably roll through the traps at 120 (450ish hp)

Our transmissions are set-up for a broader TQ band, you may need to see if you gan change the internal gearing to a shorter gear to take full advantage of where your power is.

there is no way your curve came out that smooth. that has def has some massaging done to it.

shawn, notice your AFR at the bottom of the sheet. kinda lean as well....some levels avove 12.0. with that much boost...you should see some knock, and that would show a dent in that graph up top. I have never seen a pull THAT smooth either......

Thanks guys keep them coming. If you have access to others those would be great as long a partial mod list is available.

Now that's what I'm talking about! I am looking for similar numbers, but peaking a shade earlier.

Wait until it's at 20+ psi in the spring. 13psi is winter mode.

550whp is the goal I think, for the XP cam.

PS. That's my buddies car (With my heads studs, Gaskets, valve springs, seals ... and a bunch of other stuff lol !)
