I did two runs, one with the Dragon digital box and one without. It was a portable rolling road at the Halfords Ripspeed X open day, so the figures should not be considered accurate, but the graph does show what difference the box makes. The box was set to '11' (default setting), and the graph shows power in BHP and torque in lb/ft. The bold lines are without the box, the thin lines are with it.

Interesting how the box affects the mid range, more than the overall figure.

Looks pretty accurate to me I think.

Looking at the graphs it does pretty much nothing at the top end. Although, i didn't expect to see massive gains at the top end anyway. I've always felt that the box helped most in the low to mid range, and this has confirmed my suspicions. I'm quite pleased with the power curve though. By 2600 rpm the engine is virtually at peak power, and it stays there until after 4000 rpm.

TBH, i was suprised at how civilised the Fabia was on the rollers compared to all the petrol cars that went on. The Fabia didn't make too much noise, virtually no smoke, and put out a torque figure that monstered all of the FWD petrol cars (beat a few on BHP too ). There was a Rover 200 Turbo Coupe thingy there that made loads of noise, smoke, and flames, and only managed 146 BHP. The owner was not happy, as apparently it had been putting out 240 BHP a couple of months ago...

There's always one!

At a recent RR day down here I had the highest torque on the day out of all the cars there, including a sweet looking Skyline that could only muster up about 230 lb/ft.

Lol, this guy did 3 runs, convinced that the fault lay with the rollers and not his car. Plenty of people had been on before him, including some 'box fresh' cars that got VERY close figures to what the manufacturers quote.

Just shows how accurate the good old "butt dyno" is.. Reminds me when I bought my 406 turbo and thought it felt fast. Anyway we noticed my friends car (he had also the same car) felt a lot faster, just could not notice it until doing A-B comparison. Finally we took the good old boost gauge just to notice the car was running 0.2bar boost while the car should run 0.5 bar from factory.. couple of dyno runs confirmed our belief, my car produced 120bhp while my friends car had little over 150bhp.. the fault was in the wastegate actuator mechanism so the wastegate was half open all the time and thus leaking boost..

The beauty of the Furby is that it's effortlessly nippy

A petrol turbo requires a lot more revs to get that power - admittedly then they are awesome though :D (before this turns into one of those threads....)

@jtstatic - you must have been gutted yours was coming out that much lower, but then finding the problem must have been a good thing

yup, I was devastated and I just had bought the car used anyway we went to the dealer with a dyno printout and they had to fix the car because they didn't want to lose their reputation.. cost them over 1000euros to fix the car since the whole turbo had to be removed and it's not easy in a peugeot (you have to remove a lot of stuff to remove the turbo and you have to do it from underneath the car).. they also had to fix the clutch as it was also done and started to slip once we got the turbo working. Anyway the car was fun to drive for the 1 year I owned it, very powerful engine for a petrol and handled like a dream for a big saloon, it had almost diesel like torque and with upped boost it was fairly quick putting 190+ bhp, surprised a lot of cars with it since it looked just like the basic 2.0litre version which is quite a slow car.. anyway had to sell it as it was too costly to run

Vroooooooooooooooooooooooooom....taka taka taka....

i have full torque at about 3k with ym 1.8T :P

Actually with soundproofing added the Furby is fairly quiet, engine-wise at least. I've got a fair bit of soundproofing now though, and before adding it, clatter noises were quite audible when the engine is cold

As for not smoking much, hmmm, I'd be surprised if there wasn't a little smoke screen laid down every once in a while

That sounds pretty low for a Skyline - was it a GTR? My Scooby turbo was putting out 231lb/ft of torque lol and that was slower than a Skyline!

Right, for a bit of a comparison i've logged the torque in vagcom, calculated BHP from that, and then plotted it in Excel. Interestingly, the peak torque figure from vagcom is almost identical to the figure from the rollers. The peak power figure comes out about 20 bhp higher at a smidge over 150bhp, but i suspect that's at the flywheel, whereas the rollers measured at the wheels. Odd that the torque figure is a spot on match though. Anyway, here's the plot...

sorry mate cant make the graph out.( cant read the small numbers lol)what was the before and after torque and bhp figures?

I agree, it's quiet as standard though - took an A3 TDi for a test drive at the weekend and the guy was going on about build quality and sound proofing - SWMBO asked if the exhaust was broken because it was so much noisier than my furby. :thumbdwn:
