AS elmo eluded to earlier. There are some preliminary numbers from a stock block 350z HR. This is a stock block with over 80k miles on it and over 40k of those being boosted and beat on. Needless to say the motor isnt the freshest in the bunch and there is room for more potential.
They started with And ended with @ 5 psi:
400rwhp and 326ft/lbs @ 5psi of boost
Then after the install with the same dyno and same tuner were able to crank out
430rwhp and 341ft/lbs @ 5psi of boost
Analyzing the graphs we can see that the intake manifold allowed for more aggressive tuning without compromising reliability. The highest gains we can see are a whopping 42whp and 48ft/lbs at 4600rpm! the numbers just didnt stop there. We can see that the intake made more power throughout the entire power band! With the peak power climbing an addition 30whp and 15ft/lbs at the top. Proving that this part does in fact make power and will also make power on any 370z with forced induction.
The intake also allowed them to run more boost safely within the tuners limits or 9psi pushing out the following numbers:
@ 9psi they were comfortably sitting at 523rwhp and 400ft/lbs.
This is further evidence that this is a mod that will help your gains no matter what the internet naysayers think, there was R&D done on this product and the numbers will speak for themselves.
Stay tuned for more updates from those of us waiting on dyno time.
