We have had extensive conversations with said customer on this topic of why he wanted to drop displacement and it came down to usable power. The said customer on his "Base" tune and I will repeat this again his Base tune on waste gate pressure was making over 800 ft/lbs of TQ to the wheels by 4000rpms. This was 325 more ft/lbs than he had on his last intake setup. His spool came in over 1000rpms sooner than his previous setup and he was making hundreds of hp and tq more mid range power than his previous setup. And because he still drives the car on the street and with this much TQ on demand he wanted to change the characteristics of the car. Any real tuner will tell you that there is only so much you can do to minimize TQ. Given his extra .8L of displacement over stock he had more power than the chassis and tires could handle that early in the RPM range. This is something he found out first hand at the top dawg event and Zdayz mountain runs.

Given his experiences with the car his best solution was to drop some displacement and in the process he has partnered with us on an ultimate closed deck block that will be the pinnacle of what we offer. It starts its life off just like the closed deck block that cosmo is running in his new build but with all the upgrades we can throw at it.

Anyone stating that the stroker motors dont make power do not have enough experience in the industry or in this platform. Our Gamermodz sponsored Z is the current 350z world record holder making over 1100hp on a 4.5L... so yes they make power...

Lets keep everything factual here and not subject the forum to conjecture that is unfounded and based on ones opinions
