Message: [QUOTE="Power Hungry, post: 523108, member: 1375"] I got the wheel installed and tested with the STOCK 38R ported housing. I'm pounding through that data now. I still need to test the DieselSite modified housing to see if it offers any improvement with the new wheel. All those results will be posted in a separate thread dedicated to the 38R sometime in the next 24 hours. Question 1: Just to clarify, the 399 HP I achieved was with a particularly aggressive timing curve on a 40º day. This is NOT the setup I run day to day. I'm currently running about 6º lower timing because I don't feel like replacing the head gaskets or the rods & block just yet. ;) With that said, additional air is only going to be of use if you have excess, unburned fuel. In the case of my truck, I was already running pretty clean so I only picked up about 20 HP with the additional air. Plus, we have to take into account that there may have been some thermal losses (or maybe gains?) related to the heating of the air as it was compressed an extra 10+ PSI. There is still a large amount of data to go through and I have some loaded cruise testing I still want to complete to get a better idea of how the truck responds under normal driving conditions, not just at WOT. Results will be forthcoming as the tests are completed. Question 2: I'm setting up a battery of tests on the dyno to simulate different load conditions, grades, and other stuff. I'm also planning on running at different performance levels on the chip to simulate an otherwise stock condition. The results should be quite interesting. That would be fine. Just get with Bob to purchase the wheel. If you want, we can dyno the truck to get stock numbers and then after you install the wheel we can run the truck again to get the new numbers. If you want us to install the wheel for you, it would be $125.00. We'll cover the dyno costs. Let me know how you'd like to proceed. Jason, you're gonna love this new setup. :D [/QUOTE]
