View Full Version : DYNO'd Scion xB w/ AEM CAI EV_AIC-xB 10-05-2003, 08:02 AM Borla Performance Industries Dyno'd my car last week and here are the results of the dyno... Stock xB motor w/ AEM CAI http://www.autoimportcraze.com/images/cars/AIC-xB/xB-dyno1a.jpg Does anybody have dyno info on a completely stock xB? ScionVan 10-05-2003, 08:12 AM http://sr20.hybrids.jp/van/scion/xb_on_dyno/ 93.4hp, 98.4 ft-lbs http://sr20.hybrids.jp/van/scion/xb_on_dyno/images/07.jpg avus 10-05-2003, 08:27 AM 90.48 hp/ 94.36 lb these numbers include the Borla exhaust, or just stock motor and CAI? EV_AIC-xB 10-05-2003, 08:55 AM The dyno is not with Borla exhaust... i'll have dyno results with exhuast posted Monday night scionlife 10-05-2003, 06:12 PM ScionVan, What does the fourth dyno run mean? w/o exhaust and FILTER COOL DOWN? It looks like only seven minutes went by, so it couldn;t mean that it was on a cool engine. Does it?

It looks like only seven minutes went by, so it couldn;t mean that it was on a cool engine. Does it? Darren I don't know, as the other times are pretty tight too. Six minutes to remove a hot muffler is pretty good! The huge problem with dyno results is the need to make the runs on the same vehicle while changing only one parameter at a time. You cannot compare EV-AIC's results with ScionVan's because any increase would be hidden in the "noise" of variations in temperature, humidity and vehicle-to-vehicle variations. Getting good dyno data is not an easy exercise. George eric_m 10-06-2003, 03:25 PM you guys can't compare dyno runs taken with different dyno machines on different days with different temperature conditions. the AEM intake only makes 1-3whp and it will be hard to notice that when comparing a baseline dyno from one place and a modified car from another place. ScionVan 10-06-2003, 09:41 PM I think that muffler was removed in less than 3 minutes actually... And the same for the airbox... these cars are EASY to work on! Darren: The cool down is after we stopped the car from the previous runs, shut it down, and ran two fans over the engine to cool it down for a couple minutes. Interesting to see that even with that minimal cooling, a little difference was made. And George and Eric are correct... you can never really compare numbers from two different cars measured on different dynos on different days. Dynojets are good for measuring relative changes in hp though. So in the case of our dyno session, it did allow us to determine whether we were gaining or losing hp, and it gave us a general idea of how much hp and torque that particular car was putting down on that particular day under those particular conditions. eric_m 10-07-2003, 05:43 PM i think that 90+ hp for our engines is really good. seems like crap, but it's actually a decent power to weight ratio. if we had 140whp our cars would fly. bBOXD 10-08-2003, 03:51 AM What type of Dyno was this done on? Dynojet, etc...? Did you have rims on the car or were they stock wheels? Mark sammyphsyco 10-10-2003, 03:45 AM if runs made on dyno jet dyno's, the results are comprable and repeatable . there corection software is very good and accurate. i have 7 years experience with motor cycle and diesel engine dyno tunning and dyno jet is by far the easiest to use.
