I guess they're just freaks or it's poor dyno operation... Link to comment Share on other sites More sharing options...

"yea right buddy, its just a high reading dyno"The bloke said he had a stock BA-Turbo with an exhaust/tune (only) on it the other week and it ran 204 rwkw's on all the same settings...I dunnoThing is though, mines a BF 1 (Feb 06 build) I'm pretty sure it doesnt have all the toughened up internals, just some bits n pieces.

"yea right buddy, its just a high reading dyno"Hate to burst your bubble, but keep thinking that. your car given the correct corrections only makes approx 205rwkw which is about right for a standard xr6t BFThe bloke said he had a stock BA-Turbo with an exhaust/tune (only) on it the other week and it ran 204 rwkw's on all the same settings...Yeah its not a settings thing, you cant change any corrections in shootout mode. But placement of the INTAKE AIR probe is what caused the problem.. But last time the INTAKE AIR Sensor did not fall against something hot and cause ridiculously high air temps changing the correction factor to the likes of 1.3I dunnoThing is though, mines a BF 1 (Feb 06 build) I'm pretty sure it doesnt have all the toughened up internals, just some bits n pieces.Bog stock BF xr6 turbo with nothing done.Ok. just done a quick calculation, at 187F intake temps, using this page http://wahiduddin.net/calc/calc_cf.htm your car is realistically making approx 205rwkw, with a correction factor of 1.171 (205 * 1.171 = 240)..Go back to him and tell him to run the car on the dyno again, and this time put the INTAKE Air temp probe where the air goes into the filter, Not on the radiator, or somewhere excessively hot 86degreesC is excessively hot to be measured on the IT probe. it should realistically be very close to AT, Air temp of 25 as measured on the dyno sheet.

"Temp" 83.6degree's C.. The placement of the intake probe is totally wrong. Link to comment Share on other sites More sharing options...

Measured by the weather stationIT = Intake Temp. Measured by the intake air temp probe usually placed near the air feed of the air filter.There shouldn't be any more than 3 -5 degree's difference between those values.. And sorry, just looking at your dyno again.. 230rwkw it shows, means approx 200rwkw * 1.171 = 232rwkw.. So you have approx 195 - 200rwkw.. You wont know exactly as I've approx calcualted that correction value based on the 86 air temp.. so its only a approx calculation backwards Link to comment Share on other sites More sharing options...
