I've visited this site for years for info, but this is actually my first post. Due to some driveability issues since adding the cam I decided to have my car dyno tuned and to get a custom chip. The gentlemen that did the tuning has been doing this for over 25 years and has done numerous 5 liters over the years. My question is over a little disappointed and confusion with the results of the dyno runs (mustang dyno by the way) My combination bested about 240hp @ 5,300 and 245tq @ 4,000. I'm not all that concerned about peak horsepower as this is a road course car and definitely not a drag car. I've been very careful to try to match parts to maintain the majority of the low & mid while gaining some up top. Do these numbers strike you as unusual for my combo? I thought I would have produced a better peak horsepower, but I was really shocked that my torque was kind of weak. I wish I had the charts electronically to share, but I just have hard copies. The tuner was very happy with my air/fuel ratio and the broad power band that the car did have. Another point of reference for his dyno is that most of his blower (9lb kits) 5 liter cars net 320-340 rwhp. Figuring a blower add on my car, I may not be that far off on his scale anyway.
I know trying to determine which dyno is best or who is the best dyno tech is an argument that will never be settled. I thought that looking at the hp and tq relative to one another (regardless of the actual numbers) that the peak tq was a little low. Any thoughts would be appreciated, from reading posts in the past I know that some of you know a hell of a lot more than me. Thanks!
