Dyno Results: +107WHP and 137FT-LBS
Hey guys, it's been a busy month for us and I just wanted to share one of the highlights, specifically Rudy's Camaro ZL1. He came to us with his car which had already been skillfully modified by the guys at Hennessey Performance Engineering here in Texas and he wanted to add a few upgrades to make a "little more power". We installed a Metco 2.5" diameter supercharger pulley, worth about 3 psi, and ported the supercharger snout. We then built a custom ice tank to lower the temperature of the coolant for the intercooler and consequently the IAT's, and went with a dual nozzle methanol injection system. After the installation, the car needed to be tuned for the new modifications and we were rewarded with an astounding 107whp and 137ft-lbs of torque! As if this car wasn't already a beast, it's claws just got a little sharper.
 Enjoy the video. Last edited by KCS; 05-21-2013 at 03:00 PM. |

so you gained over a hundred hp and trq just from adding the ice box and upping the meth injection?

My bad guys. In addition to the ice tank and meth kit, we also swapped to a 2.5" supercharger pulley, worth about 3psi, as well as porting the supercharger snout and a Nick Williams 102 throttle body. The ice tank and meth kit is what I thought I had overlayed on the video, but its a before and after of everything. Pulling graphs right now and will have them up in just a bit.

Did the Z have single nozzle meth from hennessey already or was that a new addition completely?

Do you have any pictures of the dual nozzle setup?
