Finally I got around to uploading the video of Sean's and mine dyno video from the 2007 SC/XR7 Shootout. Sorry for the poor sound quality, the file was to big and it had to be cut down to fit on streetfire.
Some notes from the dyno: Sean's water pump bearings started dragging during the dyno so he did not get the numbers that he expected. We swapped the water pump after words and Sean said that he noticed a difference in power. I dont know the actual numbers that he put out so he will have to post them along with a list of mods.
Me on the other hand was very disappointed with my dyno results. I am down 100rwhp More or less it made 234rwhp when it should be at somewhere near 330rwhp. After having Precision work on the car for a solid hour after everyone had dyno'ed we came to the conclusion that I need more jetting because the car keeps going lean. I've since then done a once over on the car and figured out that I am going to need a new primary power valve, more jetting, new spark plug wires, and a carb rebuild kit. Whats nice is the parts I need are incredibly cheap The new set of plug wires is needed cause I have spark jumping from wire to wire and what not. Believe me, the MSD sure bites hard I have all winter to fix it so I am in no hurry. Probably around the first of the year I'll tear the carb apart and rebuild it and by early march have it taken to a shop to get tuned to see if I have regained that 100rwhp that my car should be making.
Let me know what you guys this about the video and what not.
'92 SC with 306ci swap and '89 XR7 mostly stock dyno video.
