Ruf intake with 2"catback and V-AFC2 = 73.1 kw

refer back to the image jus-10 attached :)

It was putting out a bit over 68kw with the exhaust and everything else standard. I never had it dynoed with the stock exhaust, but I am only guessing that it doesn't add too much...I couldn't tell the difference when i had it fitted so I assume it is onl;y very slight....

ive had my car dynoed again after i cleaned my airpod, it seems to be louder and hissing noise is much louder maybe it needs more oil, with standard airbox its about 60kw @ wheels, with pod its just above 64.4kw and now with muffler its 66.8kw, tried with muffler off and on twice and everytime it dropped bout 1.5kw both times so i would personally see full exhaust give somewhere around 5-7kw atleast. Would love to go full exhaust but selling the car soon so not sure if i want to spend anymore money on it.


mate has my dyno sheet, ill ask it for him, its on same paper as the bloke dynoed both of our cars for one price

wasnt dyno dynamics

You serious muli?

What dyno were you running it on? A Dyno Dynamics in shootout mode?

It just seems like a pretty huge difference....and I honestly could hardly notice any improvement when I had the exhaust done....

Do you have a copy of the dyno to put up?

Is it true to say dynoing the exact same car on different days (= different temps, air pressure, humidity, petrol content), could give +/- a couple of kw difference?

a header does make a good contribution to the increase of the kw.....

Yep true...also simple things like the way the car is strapped down on the dyno can influence the readings. This is why we left the car strapped down at all times when doing the testing for the intake.

It's also why dynos should primarily be used as a tuning tool (well that's what they are).

That said the differences shouldn't be massive if you are doing it in relatively similar conditions...I definately wouldn't be expecting something in the order of well over 10% difference from dyno to dyno

That's why I'm interested to see muli's dyno sheet.
