Just when I think its safe to poke my head out from under the deck.... :wtf2:

everyone needs to relax...VVEL tunning should yield 50-75rwhp

Nissan Variable Valve Event and Lift (commonly abbreviated as "VVEL") is an automobile variable valve timing technology developed by Nissan.
Nissan VVEL was first introduced to the US market in late-2007 on the 2008 Infiniti G37 Coupe sporting the new "VVEL" VQ37VHR Nissan VQ Engine (VQ37VHR motor specs: 11.0:1 CR, 95.5mm bore, 86mm stroke, 7500rpm redline). VVEL variable valve timing is now also used in the smaller VQ25VHR engine seen in the Infiniti G25 and the VK50VE V8 engine from the Infiniti FX50.
A rocker arm and two types of links open the intake-valves by transferring the rotational movement of a drive shaft with an eccentric cam to the output cam. The movement of the output cam is varied by rotating the control shaft with a DC stepper motor and changing the fulcrums of the links. This makes the continuous adjustment of the amount of the valve's lift (e.g., the amount of intake opening), during the intake valve event in the four-stroke cycle, possible. C-VTC and VVEL together control the valve phases and its valve events, allowing free-control of the valve timing and lift. This results in more efficient airflow to the cylinder, significantly improved responsiveness, optimizing the balance between power and environmental performance.
It performs similarly to BMW's Valvetronic system but with desmodromic control of the output cam, allowing VVEL to operate at higher engine speeds (RPM). Other similar systems are offered Toyota (Valvematic).

I thought we needed this to clear the images of 'crack' from our minds...

you gotta do gears man! the funnest most rewarding MOD hands down

300rwhp just isnt enough anymore

DD Z + 70-80% highway commute = no gears mod for me. I plan on using it as my DD for as long as I have it. Also, I probably won't get the torque converter either. I have no interest in drag specific mods. I would rather get mods that would allow me to get on a road track (oil cooler, brakes, etc.)

The term 'crack' is being used because in software you hack/crack something to do with it what you want. To control VVEL we will be hacking/cracking the software for user control.

It was more Steve's "cracking" haggomyeggo that I wanted to shed....

If VVEL was tuned to balance performance with environmental concerns, that means it is a compromise. And when there are compromises, gains are left on the table.

Either way, everyone seems to think this VVEL "crack" is going to be simple and is going to yield unbeleivable results.
