2.2 TDCi (Puma) CAT Delete

This discussion- irrespective of how informed or otherwise, all helps to add to the body of knowledge.
Until someone fronts up with back to back dyno graphs, and temp logs, heck even chuck some exhaust backpressure graphs in there, then you uneducated guess is as good as anyone elses. If you disagree- add to the data and put some cold hard figures out there. Go on, be a hero. For science.

IMO, if it weren't for people shootin' the breeze and throwing ideas and thoughts out there, there'd be no innovation in the world.

kinda like the debate here, but would like some conclusive evidence either way. ...throw in nuggett's sealed airbox kit into the test whilst at it.

Perfectly sums up a Defender hey [emoji41][emoji48]

As a psychologist said to me, and she repeated it often.
"we're all dickheads. The day you realise this, that you're not someone 'special' is the day you can start to get some real understanding about yourself and others"
I love psychology. :)

Well, as I explained to a mate when a GTR pulled up beside me in the Deefer.
"Turbocharged, injected, all wheel drive, four spot calipers, slotted and vented discs, hey, I'm driving a GTR equivalent!!" [emoji23]

as a recent de-cat recipient, i've graphed the performance differential here:

Much zoom.
Very wow.

jokes aside, i am actually curious as to what my 90 is pushing out. Obviously it's too late to do a before and after on my vehicle.

But, if i stump up to take it for a ride on the dyno (std map and 170 for interests sake), can someone provide a standard (with cat) 2.2 graph?

I know it won't be an ideal comparison but surely it'll be indicative ?

You can see variations between dynos. Different programs that they use to calculate HP, correction factors etc.
Then atmospheric pressure, ambient temp, etc etc etc can come into play. Heck, even oil weight, engine machining tolerances would be throwing out inter-car results.
I think you'd find the variable you wish to measure will be lost amongst all the other factors at play.
But throw some data out there, I'd love to see it. A decent sample size of vehicles would give extra resolution to the conundrum.

Yeah, but some have more nuts than others!
