17hp on the engine dyno with a totally stock engine. They are testing this week on a chassis dyno, for more results. Release date is 2nd week of Sept. Thanks for the support.
To me, the biggest benefit of this plenum, is better power production up top. Can't wait to test it on some high boost Z/G's!
Oh, and it look incredible....carbon fiber caps are included.

Thanks Sharif!
Can you confirm the price? Also are you going to be hosting a group buy once you test it out?

I would guess the CF sides are the extra $200. Well worth it! I wish you could order it polished!

I want some more Tech info.
I know on my350z there are more but how about sharing it on this side.
How are the variable stacks going to work?
What do you think this will do in a APS TT FI @7PSI?
Do you think a retune will be needed it for this?
I know we can get more power if we want out of a TT system on a stock block but how do you think this will affect power output on a stock block?

Any plenum change would require a new tune to get the best performance.
Either way the stock rods are only good to 450whp at best...

Would adding something as this help the car get more HP with less stress on the motor?
Basically if you had a bottleneck and supposedly pushed the turbo's more to get the same power.
Wouldn't that strain the motor more to get the same power?
so if this frees up some bottleneck could you get the same HP with less stress since your not compensating on the bottom end?
