Maxx abbiamo prove concrete che il filtro stage 1 K&N produce meno HP (almeno 1.5) del DNA quindi ti suggerirei al piu' presto di comprare un filtro DNA stage 1, infatti guardati un poco queste prove:

ciao CaptMoto cio� al posto del filtro K&N devo mettere il DNA ?

Si!! :sbike:

Nice work but how did he adjust the fuelling?

You do not say you have a PCIII or other fuel device, but I can see from the A/F ratio on the dyno sheet it has been altered. You would have got some more HP & Torque if you ran it richer in the lower revs around A/F ratio of 12.8:1 2000/4000 rpm.

I agree with Kev.

There is a very noticable power dip below 4000 RPM.

The low end RPM range is getting way to little fuel. Fix that and you will pick up a lot more torque at the low RPM ranges.

The gains at the low end might even carry over and give you another HP or so at the top end.

What altitude is this dyno?

With the mods you have in there, the HP is a bit low.

It migth be becuase you used a knobbly tyre.

If you did the dyno with slicks, then the HP output is actually very low. It should be around the 55HP mark easy with slicks and the mods you run.

I didn't did the test with the slick tyres but with the knobbly tyres and the pressure was controled. I too was a little worried about the low HP but the meccanical told me that in Italy we use the Fatt. Corr. EEC (like you can see at the graphic), this parametre correction change sensibly the results of the test.

I run nearly the same setup.


I changed my dyno run to the same correction factor that you used: EEC, 5.

Now this is the normal correction factor that I use. STD, 5.
