I'm taking my car to the dyno with our local F-Body group here in CO on Feb 9th. They really do not know much about GN's/ TR's etc. I would like to really impress them, so I'm looking for some tips/ technique. This will be my first dyno session ever, but I have a basic understanding of how they work. My setup is basically stock, K&N w/ home made cold air kit, LT1 MAF and translator, AFPR, stronger silicone hoses, adj wastegate, stock chip and Thrasher chip, Walbro 340 fp (hotwired), pinon snubber, engine tie down and volt booster. I do not have a Scanmaster, but I do have a Scantool that tells me everything I need to know. I have heard of a trick that helps. It's just re-aligning the turbo and IC so it's a straight shot. Has anyone tried this or even heard of it? Race gas is hard to find, but I know where I can get some 100 oct and I also have access to Xylene/ Toluene. Is there any way to increase the octane rating of the 100 oct by using Xylene? I'll be running a base of 16-18psi and if I can get the oct high enough, I'll push it up more. Any other hints, tricks or tips? I know I sould let my car cool down for 30 min to and hour inbetween runs due to heat soak. Any predictions as to what HP and torque I might throw down? We're at 5800 ft elevation. Thanks for the help!
