Okay now for the charts. The people were nice and seemed to know what they were doing, but after the first run I told them there was no way their dyno #'s were right. They said that the Mustang Dynamometer usually give's lower #'s than what people expect. They said when I got home add up my flywheel HP at stock then add up the flywheel HP in mod's, then subtract 18% for drive train loss and the #'s should be close. The place was a nightmare to find in down town Louisville and to make matters worse, I had forgot my wife's camara there. I was just so shocked about the dyno runs I totally spaced it, I was already across the bridge back in Indiana and had to turn around to go back & get it

. I've got an email ready to send to them when they open and I can get hold of them on the phone, so I'm just going to copy & paste it in this post. They had also told me I needed to call RENNtech about their tune, I'm really dumping the fuel to it @ top end. They could not do data logs because they didn't have the software to do so.
Hi Cindy, when I got home yesterday I done some number crunching. And I don't think there is any way the numbers were right on the dyno runs. The car didn't even reach what a stock SRT 6 should have by doing calculations of 18% drive train loss. Below are some numbers I came up with, the car "stock" is rated at 330hp at the flywheel and rumor has it it's really 349hp because the MB part of Chrysler didn't want MB people to see it as the 349hp that the more expensive MB was. So I'm being conservative and calling it 330hp in my figures.
Stock = 330 flywheel hp - ( 59.4 = 18% drive train loss) = 270.6 rwhp.
Stock = 330 flywheel hp + 45 flywheel hp for the RENNtech kit ( guaranteed minium) - (67.5 = 18% drive train loss) = 307.5 rwhp.
Stock = 330 flywheel hp + 45 flywheel hp for the RENNtech kit ( guaranteed minium) + V-8 supercharger "Y", intake hose's & K&N filters 15 flywheel hp ( modest estimate) - (70.2hp = 18% drive train loss) = 319.8
My highest run was 266rwhp. I can not get on to the RENNtech company when I myself don't even believe the rwhp numbers are right. I do believe the A/F ratio's, but I can't really get on to them about that because I know they would say if Auto Motions dyno numbers can't be right how can you expect the A/F numbers to be right. You guy's were very nice and good people to work with, but I feel like I wasted a vacation day, $65 for the dyno and $55 in gas to get there and back.
The first pic is a run down of #', 2nd is the 3rd pull - (the probe came out of the exhaust so they just printed out the HP/ TQ). The 3rd pic is of the 1st run and the 4th is of the 2nd run.
BEST RUN A 266 RWHP, I don't think so!
