My Dyno session

[SLC Detailing]

As said in a previous thread i took my car on the rollers yesterday at QST. Here is the graph from my best run:

What do u think?
This is the best i can do at the moment.

I think you need to make it legible dude.

[Blue_Thunder]

As Rolf used to say... "Can you tell what it is yet?"

[SLC Detailing]

Not got a scanner so i have ad to try and take a pic of it. Ill try and zoom in and paste that one up

I don't reckon 217 wheel hp = 344 flywheel hp, more like 80 hp loss so 297 at the flywheel. Assuming I've read it right of course.

[AdamS4]

What mods have you done ?

127bhp is alot of transmission loss

[SLC Detailing]

I thought that was a lot and yes u have read that right. No main or pre cats. RS4 intercooler and remapp. Its more than 297hp thats for sure maybe the wheel HP is wrong

[flashyg]

it always reads like this from that dyno.

[DavidT]

Well I reckon the flywheel figure is about right then, depending on how much boost it runs. Loss should be around 80, so the wheel figure should be 264

when i took the car there it showed summit like 213 at the wheels..i wasnt impressed with kim,s dyno 1 bit..
steve you have to compare it with the 2 other dyno graphs u have for the car..
but like ive already said..having 522nm before your map tweak and now having about 485nm to me thats going backwards..
thats de-tuning in my mind not tuning..adjust ya driving style to suit the car,s performence not adjust the state of tune..but like i said..your money your car..

QST's Dyno has always had this problem, Kim will tell you the final figure is correct and the wheel horsepower is wrong. Since the wheel horsepower is what the crank figure is calculated from it's very hard to believe any of the figures.

[SLC Detailing]

344HP to me sounds about right though considering the mods it had had done to the car. Having said that the car according to Kim is not running much boost. Peaking at 17psi is this right? Kim said it should peak a bit higher then back off to around 17psi.

[clubsport]

344bhp on K03's not running much boost???...How does that work??....I am no expert, but thought that was certainly close to the expected limit of a K03 equipped car.....genuinely interested to know..always good to learn.

[DavidT]

I guess its 17psi @ 4k rpm falling to 10psi at the redline, which is the limit for K03's I think.

[jeffw]

I would suggest to take it to another Dyno if you actually want to know the wheel (and real) horsepower figure. Surrey Rolling Road is in same part of the country as QST and the road seems to give 'proper' wheel figures. Woody has a graph from Surrey RR already but the car wasn't running right at the time.
