Stock panel filter vs Green panel filter...

[MaverickUK82]

Hi Guys.

Just got back from having my intermediate service, oil & filter change.

Also got them to give it a run on their dyno. I had the run because I recently changed the stock panel filter with a green one.

The dyno runs were within 4 months of each other on the same machine with the same technician. The only difference is the panel filter and the ambient temperature.

The dyno team advised me that the Dastek dyno takes ambient air temperature and pressure into account.

The results are in!

There was a 1.1bhp increase (which I agree is negligable and could be caused by anything, however, the power on my WR1 since installing the filter has come in earlier, and where it used to trail off, it doens't any more...

Have a look at the graphs for yourselves - I'm really happy and it didn't cost much at all.

The graph shows my last dyno run vs the one I had today - check it out!

Sorry about the big file...

So you got 1bhp cause of the more dense air with it being winter,
So the green panel filter gives no gains

There are corrections applied for air pressure and temperature, although, I did mention the 1bhp is negligible.

The thing I am pleased about is that the way the power doesn't tail off at the end from 6300rpm onwards. That's quite significant I think.

The power also comes in earlier...

Any thoughts on this?

after reading this topic earlier last week decided to get a green filter and try myself, and yes it seems to perform a little better on responce quite pleased with it thanx

What do you think of the power curve (anyone), would a remap bring the power in earlier,.... apparently the WR1 has peak powere at 5800rpm, mines nearer 6300... can a remap cure this? bring it in earlier... check out my dyno report thing further up the posts...
