The full story will be hitting the newsstands soon, but until then here's a another video of our testing on the 735hp, stock longblock LQ4 we picked up for $900. 

On this run we only made 621hp on a 125hp shot of ZEX nitrous. Only 621hp, hahaha!

 It almost seems too easy to make power with an LQ4 and the right parts choice.

As a reminder, we started with a 2003 LQ4 with 198,000 miles on it, added a FAST LSXR intake and fuel rails, FAST throttle body, and a ZEX nitrous system. What we got was an unreal amount of horsepower and torque per dollar invested.

But the good numbers started coming in early, as you can see in this video where we made 621hp on pump fuel with only a 125hp shot of ZEX nitrous.
