That's a pretty expected figure Mikey at 13PSI and 11:1 AFR. I did 276 at 15PSI and 12.5:1 AFR so your is pretty ball park. A couple more weeks and we will have a play
Looksa little high, with those tq figures you'd be looking at 350rwkw HP = (Tq(lb/ft) * RPM) / 5252 HP = (482*5000) / 5252 HP = 458HP RWKW = 344 @ 5000rpm
looks like it was run in 3rd gear though, should be going faster than 180km/h in 4th at 7000rpm. that might explain the higher torque figure.
Most def was in 4th gear - I was sitting in the passenger seat... Not sure exactly what revs it went to, but it wasn't redlined. I have the multichecker set to alarm at 6800 and that never happened...
That graph is f**ked...the x axis definately goes up to and beyond 180kmph, yet the index underneath says 144kph, which would be about 4500rpm(ish). With your turbo's mike, reved out to 6500-7000rpm, you should be making a fair bit more HP than the 250rwkw.
right my mistake...max power @ 158km/hr or 5000rpm...seems a bit low. Max power for me was 6500rpm and my turbo's are stockers. (still hate the graph btw...it just looks wrong)
144km was max torque, 158km was max power so it says... I dunno wtf to make of it, but they were having calibration issues during the day Time for a trip to the strip?
Did you get any stealth tuning done on it over the weekend? Seat of the pants says it making a fair bit more than that dyno indicates. I wouldnt be too bothered by the dyno graphs, the main thing is it makes good power, runs well, pulls hard and still bloody goes. Get it tuned and have fun with it.
Nah no tuning done as yet... Having a good look thru some maps today tho - just comparing and contrasting... Not real fussed what the dyno says (it said I was running 20psi), I'm just enjoying having it back on the road
Nice work Mike. Just for refference/comparison. Had a tune about a year ago. From EFI on the Goldy. Very similar mods to yours, though not as fresh a motor as yours. 309 rwkw 495 Nm torque Enjoy. Regards.. Dave
I'll get there pretty easy I think with more boost and tuning... Had a little play last nite and it is much faster now. Fuel pressure was set way too high (set it with the vac line connected) giving shitter a/f's... Dropped the fuel pressure down to 45 from 50something... A/f's look much nicer now
