Mustang Dyno numbers? and A/F I was on a mustang dyno for the first time and I have alot of questions...not sure everything was right. The procedure is different than a dynojet. I had to take the car to 105mph for a parasitic test before dynoing. They needed to know the car weight, and test mph and rpm range. Also software wanted model but was only updated to 1996 so LT1 Firebird was put in.
Overall I got 380rwhp and 330 rwtq and the curves look perfect. A/F ratio started off at about 15:1 then dropped to/leveled out at 13:1 at about 4krpm. Car has been running a little rich and cool. O2's were in the 910 range and Ltrims were less than 10 during the run. 4th gear with 4:10's. How would this run relate to a dynoject run? Is there a correction factor like a DJ? I dont see SAE corrected anywhere. It was hot and humid. Would leaning the car out bring the torque numbers up a bit?
Also my buddy with a 88 Saleen Mustang, 302 Bennet 2.02 heads/cam dynoed 280 rwhp on a dynojet then bolted on an A-trim Vortech 5-6lbs and dynoed 414 rwhp on this mustang dyno with a 15:1 air fuel ratio during the run. He has 3:55's and probably had more boost because of the heads/cam....but that is a hell of a gain. We are just not sure the dyno was accurate.
Any info on these mustang dynos and how they compare?
