ChrisSK Posted June 27, 2008 Report Share Posted June 27, 2008 Well, I finally had the opportunity to finish the car in time for some track duty. I was making a thread on our local board about all the work I did to the car prior to getting it to the track.. I will quote some of the posts here. Below, you will find pictures and documentary of everything I did to the car so far, pics of all the parts, and a video of the track.. Basically, on a Pulley / Intake / Gears / Drag Radials and Tune, I was able to squeeze out an 11.1@127mph. The car is insane, and I loved every minute of it. T Video: http://youtube.com/watch?v=zfBL3DZpmAk Can't wait for the Kenne Bell to come in! :happy feet: Ok, so most know we have acquired an 08 GT500 from Hoffman about 2 weeks ago. Finally, our break-in period has completed and tonight we decided to get going on the car. Tonights task was simple, just to dyno it with just a Magnaflow Catback exhaust. Most know that catbacks really do not add much to the performance of the car, but I couldn't wait for the baseline to put it on, the car was just way too quiet. With that being said, the car based at 439whp and 457wtq.. This was entirely stock except for the exhaust, no pulley, no intake, nothing.. The car has exactly 498 miles on it. Next step was to simply tune it. These cars come extremely rich, and are based on 91 Octane. With tuning the car, we remove some fuel out of the car, add some timing, and reduce some of the torque reductions. Just with a tune, nothing else other then a 10 minute cool down, the car made 495whp and 490wtq. This is fantastic info for those who just want a tune and nothing else.. Gaining exactly 56whp and 33wtq with the tune only. Tomorrow we will be installing the JLT Carbon intake, tuning, then doing the pulley and idler pulley, then tuning it again. Ok, so we got the JLT Carbon intake on.. Normally we sell the Steeda intake, but we loved the look of this intake after installing it on Kevin's 40th Anniversary GT500 we had to have one. While we had the intake off, we decided to throw in some NGK TR6 plugs and gap them down.. I measured the gap on the stock Ford Platinum plugs.. Get this, .52! It's amazing how the car even ran with a gap that large, I'm sure the ignition system has to be pretty bad ass to be able to fire an ark through a gap that big and not blow out. Either way we gapped the plugs down to .33 and threw them in. The results of the intake were pretty good. This particular intake lists for $459, the quality of the kit is amazing, and really goes in easy (about an hour install). The intake just barely clears the strut tower bar, and JLT gives you nice aluminum spacers to ensure the clearance. Overall, I like this intake, but I think the Steeda intake makes more power, simply from what I saw in the tune.. The inside diameter of this tube is physically smaller then the Steeda piece, telling me some airflow has been sacrificed for aesthetics. The results of the intake only, no pulley, were 508whp and 487wtq. We have a gain of 13whp and a loss of 3 ft/lbs of torque. Now, I'm going to attribute the loss of torque due to the fact that the car was pretty hot by the time I got the Transfer function dialed in. The car didn't get much of a cool down, so I'm assuming the torque on a cool down run, will be either the same, or slightly higher. Onto the pics, you can see the last pic, we decided to go with twin blowers to see what the power output would be :P Pulley install up next!!!
