Hi, me and Paul20vturbo went to powerstation today to have a power run, fueling check and det cans. Mine was the first one on, i wasn't sure how it would do as my gearbox is nearly gone and the noises it was making down to powerstation was horrible (high pitched humming and rumbling very very loud, not wheel bearings) My spec is- gt28rsr,sip,apexi,h&s downpipe,decat,2.25" cat back,fmic and gtec2. On my first run he said he heard abit of det at 5800rpm but then went after that (he thinks the ecu pulled the ignition back for afew seconds). The fueling was at 0.8 lambda all the way to redline which he said is spot on ( i saw this with my own eyes too ) On the second run he said it felt abit hesitant and around 5k the widget flashed [/b]THROTTLE POT FAILURE[b] Now it won't go off, he thinks that could effect my readings as at 5800 i get a big dip in my graph. Has anyone had this fault code before or know what it means. Anyway on my first run i got a good result 319.4bhp and 273.4 ibft torque at 1.35bar. Heres my pic of the graph- http://i65.photobucket.com/albums/h227/YellowAshes/P230608_164701.jpgPaul's car stats are- t28 Hybrid,pro alloy fmic,k&n panel filter, decat, blueflame cat back. His first run at 1.25 bar was good, nice flowing graph he made- 288.0bhp and 243.8 ibft On his second run he upped the boost to 1.3bar but it only made 2bhp difference. Heres the pic of pauls 2nd run http://i65.photobucket.com/albums/h227/YellowAshes/P230608_1646.jpgWhat do you all think of the results Also there did a graph with a comparison of both cars- http://i65.photobucket.com/albums/h227/YellowAshes/P230608_164702.jpg

Do you know why the drag is high as its the same on mine. I personally dont think its all down to the chip Ben

I am not sure why the drag is high, my gearbox has gone on mine and making horrendous noises so that might be why on mine. The rollers is used for lots of tuning including by Subaru themselves so i would have thought it is quite accurate. ther rollers might have high drag for some reason, but i am happy that it got 319bhp (even if it is really about 300bhp) can tell everyone that. Your chip has alot more advance then mine so will give more power, but i got very slight det at 5800rpm.

you need my full fat exhaust system to keep the torque building to give you more power

Same here even if mine is really 330bhp, but its all about the torque Agree with Jamie,you need a bigger exhaust Ben

I think jamie wants me to have his its a very nice exhaust but abit to loud for me. I am not sure why i have that dip at 5800, is it the chip or the throttle pot failure(think maf maxed out) Ash

Ash If youre getting a bit of det at 5800, maybe it's backing off?

paul_v bet your glad u havn't done a compare with ash then?. Mines running 50bhp more than it did so very happy with the results. Made for than the around 270bhp you normal get with this setup. Ash also made a big improvement on power so both had a good day. Only problem is dnt understand how they work out power drag and wheel power

Thanks paul, yeh me and jamie was trying to find my noise, which is now my gearbox . Will be round jamies tomorrow taking his gearbox out I wasn't giving it much when your nephew saw me due to the noise i had, it was only on low boost its very quick when i can open it up. I did see your car on your drive looking very nice and shinny. Ash

Hi results look good, can't wait until mine is putting those sort of figures out!
Anyway a quick question: How much did they charge for runs?
I was going to go last saturday with some people off here but my car was being repaired at motormech so I couldnt make it, but I would stil like to go as I am at the 'ring in 3 weeks!
Cheers
Paul

26 % transmission loss is again fiction. Use the estimation wheel power plus 10 divide by .9 = nearer 270 bhp approx 15% trans loss. Ambient factors look a little odd, inlet wont be ambient or below it for sure thats inflating things a bit, whats oil temp about 22deg c?

Hold on 319BHP but only 234 WBHP . For 319BHP you should have nearer to 280 WBHP. I smell pub figures If i go there i should make 400BHP

I think the power figures are about right but the power drag and power to the wheels seems totally wrong. I no for a fact my toe in is fine it had the tracking done 2 weeks ago. Also ive been on the rollers at noble motorsport with a totally standard car and made 237bhp so theres nothing wrong with my engine. And ash's car had good power for this setup as per what flea said. My torque does seem low would it be my standard down pipe?. I did make more torque this time tho paul

yep its looks that way. Both cars feel quick now and im sure mine feels quicker than 207bhp at the wheels. I am aware that they dont no the power at the flywheel. I do no for a fact that mine is allot quicker than a standard coupe
