This is from a fiesta up near round where im from....350bhp on stock internals with a 2.5stage jamsport Supercharger kit, cosworth inlet, cosworth 190degree cams, 4-1 manifold and 2" milltek, bigger throttle body and a custom map?
Very wierd power graph for sure!

Thoughts?

Thats chargers for you progressive power rate with RMP, No torque and no feeling of a shove of power, they just pull and pull. Good peak numbers, But I am sure in a track race a well tuned 1.8T k04-023 set would be much quicker as i would have more avg tq
We spent a whole day on a ST fitting a full milltek exhaust with 4 branch manifold and a stage 2 map only to gain 18bhp, but customer was over the moon spending close on a grand for 18bhp.

Nutter :laugh: He would have been better off pushing it off a cliff; instantly making it a very quick car :laugh:

Meeow!! :grin: The only thing with ford owners is that they are number chasers on the dyno, it a car is 4bhp down on what is should be with all there mods ect.. then its the DYNO reading wrong. :sad:

Atmosphaeric Preassure on the dyno is a little low?

Within reason for a enclosed dyno room at 22c, but at that time of year in an open dyno cell I would expect to see 1014mb. But it also depends which correction factor he is using, which aint shown on the graph?

my cooper s graph looked like that was awesome lol pull from low down all the way to redline was wierd but fantastic but f'in juicey !

What about the look on my face when it pulled close on 200bhp.. :angry:

ST's are cannon fodder IMO :evil: I could beat them even in the old jalopy :laugh: :laugh:

I have a nice web that shows pressures in various parts of the country and you can back date it :lipsrsealed:

Just googled it and found this.
16/07/2011 4:50 PM 18.0 °C 990 hPa,
day before
4:50 PM 23.0 °C 8.0 °C 38% 1013 hPa
Not far out.

102.9%?

102.9% is the amount of correction based on using air temp, room pressure and humidity.
Depending on the correction factors used the "corrected power reading" can vary by 4-5% by using different correction factors. SAE-J1349 - DIN70020 - EEC80.1269 or ISO 1585 some give bigger numbers some give lower number based on the atmospheric readings. The idea is to keep readings constant under all condition and all year around.

I remember Red Robin posting this link up here somewhere or on mk5 forum.
http://www.jkm.org.uk/performance/dynotesting.htm
One of the best web pages I have read to explain all about dyno numbers..

Was that the guy with the red 300bhp ED30 DSG when we were there?

Redrobin has a gti, not an ed30

cant wait to get behind it in the golf. If its really 350bhp should easily see the golf off...but worthy of a try.
0-60 times dont seem special for 350bhp IMHO

Its all about area under the curve...not peak numbers

intersting read by JKM .....so where are they supposed to put the intake temp probe on your car then when they dyno it ? looked at the pics in there dyno gallery but couldnt see anything going to the cars ?

Not a great deal under the curve on that one....its a straight line.
Would a linear line like that be better on the road as compared to something like this (ignoring the power figures)

This one would be quicker if in the same car. More hp area under the curve.
-
is the hp area under the curve worked out by drawing a line from peak power to the start (zero) of the graph??

Imagine filling the area with water, :grin: more water more power
