Tidgy Posted November 16, 2016 Share Posted November 16, 2016 One figure is at the fly 294, one at the wheels 248. However looks like whoever ran it doesn't have a clue what they are doing so could be way out. First off it should be in shoot_44 mode on the dyno, not 4f, also its been run in gear 4 where as a wrx 5 speed should be 3rd. (unless they put the info in wrong). My advice, take it somewhere that knows how to operate a dyno properly and get it rerun. Quote Link to comment Share on other sites More sharing options...
Mecka Posted November 16, 2016 Author Share Posted November 16, 2016 Thanks for replay yes he was testing at 4 gear!can you recommend any good dyno test runs?I'm baset in heathrow area! Quote Link to comment Share on other sites More sharing options...
Tidgy Posted November 16, 2016 Share Posted November 16, 2016 Not sure whos down that way tbh. Do you know who mapped it? Shouldn't look like a roller coaster and while fueling is ok the boost is doing strange things as well, typically it will peak then drop off up the rev range as it runs out of pull, not rise up the rev range. Although ignore the fueling and spool (was when my engine was fooked), see how the turbo peaks then slowly drops off, thats what i would expect to see Quote Link to comment Share on other sites More sharing options...
kershaw-330s Posted November 16, 2016 Share Posted November 16, 2016 Yes your curves just don't look right compared to mine but I have prob got a few more mods .

kershaw-330s Posted November 16, 2016 Share Posted November 16, 2016 Lol they're starting the run from far too low in the rev range too never seen a scooby start that low before :/ Sent from my Nokia 3310 using Tapatalk Quote Link to comment Share on other sites More sharing options...
kershaw-330s Posted November 16, 2016 Share Posted November 16, 2016 What does the bp 101 at bottom of the graph relate too anyone know because I alway thought it was octain of fuel lol don't know why . Because on mine it says 98.3 and tidgys 98.4 but this one 101 quite a bit of difference :/ Sent from my Nokia 3310 using Tapatalk Quote Link to comment Share on other sites More sharing options...

kershaw-330s Posted November 16, 2016 Share Posted November 16, 2016 Your power and torque should cross at 5252 rpm and yours crosses much before that something doesn't seam right Sent from my Nokia 3310 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Dyno measures power at the wheels then calculates back to give a fly wheel figure. 1 Quote Link to comment Share on other sites More sharing options...

Mecka Posted November 16, 2016 Author Share Posted November 16, 2016 Thanks guys for your quick replay.I will need to do another dyno to check my hp properly! Quote Link to comment Share on other sites More sharing options...
Tidgy Posted November 16, 2016 Share Posted November 16, 2016 basic process is take car to the right gear, then let it run down to near idle. At that point load is applied via the rollers to the car and then the pull happens. Quote Link to comment Share on other sites More sharing options...

Sent from my Nokia 3310 using Tapatalk Yes your right, my mistake, not the fault of Surrey rolling road at all, was the guy that mapped it, I'm not going into it again as there's a huge thread (or two) on it Quote Link to comment Share on other sites More sharing options...
