Great numbers! I'll have to get another ride from you at some point.

Overlay my 500whp graph if you get a chance! I want to see how the midrange stacks up. Obviously I was pushing my setup more with a lot more boost but I wanna see how different the black/bbx really are.

Here's a super crude overlay:

Is anybody going to be dragging in the "Street Appearing class" ?

^Hmm, most impressive I must say. I didn't think the BBX had this much in it honestly.

This really make me hopeful for the black with the tub mani now.

I really want a ride in this thing!

Heh that overlay is crazy. More boost is def worth more torque but I don't think much more peak whp. Yes a tubular manifold definitely helps get the BBX up closer to your Black was on the ported stocker. This tune is pretty solid, only 17-18° up top and gunning for ~30psi across the board. There's no more boost to be had from 6500+ so I don't think it has 500 in it as it sits, more timing would just yield diminishing returns.

Thanks man!

BBX is 100% stock appearing from the outside so we will see what happens :)

Nice. If nothing else I'd like to line up our cars on Saturday during open practice runs :D

Game on! My car is pretty fat and I'm a pretty shitty drive though :)

So here's an interesting overlay--my old evo8, BBK Full on alky, 30psi vs current evoX setup:

At the time I was considering going from BBK Full to BBK-B which I imagine would have looked a little something like the above overlay--a little sacrifice down low for a big gain up top. *sheds small tear for awesome stock bottom-end evo8 setup and a great car*

It's weird to me how the X's need higher boost to get the same torque as the 8/9's. If you threw another 3psi in there the top end would probably not change but your midrange would look a lot beefier in there I bet and then your old setup would only be "better" for a bit down low.

Thats a very impressive and fun looking power band!
