I'm a bit confused with the Stage1/2 filter stuff.
 

Right lads,

help me out a bit here.

I've just booked a 3 day trackday event at Park Algar in Portugal.

Plan at the moment is to use the XT660x over there. However i do have a choice of a GSXR 600 i've recently re-built/restored.

Problem is, i REALLY need more power to get the best of the track. Ideally more top end. I could in theory run a lower tooth sprocket on the rear if i can squeeze a bit more out of the bike.

So currently i'm running a stock machine, snorkel removed and a set of cans fitted.

So... this DNA stage 1, stage 2 etc confuses me a little.

I've seen Kevs threads about "if you run this you get 3bhp more, this you get 2bhp more"

But i'm still confused.

So considering my setup, what's the way forward ?

Sorry it's a daft Qn, i have honestly read stuff and am generally clued up on bikes (have done 2 recent rebuilds) but i think i'm missing something.

SO i see, +DNA stage 2 filter only, standard main filter = 3.1HP. (Best gain in HP & torque for your money.)

Now see where i get confused is

Is that all i need to purchase ?

DNA or K&N stage 1 air filter - OE replacement

PLus, if you are planning on keeping the bike then drill holes in the air filter box the ohter side to where the dna stage 2 filter is, and in my own personal opinion, fit a PC3 and get it dyno'd.

However, fitting the stage 1 and stage 2 alone will allow the bike to breath and you'll be surprised at the difference it will make

LEts remove the PC3 from the discussion right away, cost is too prohibitive at the moment i'm afraid.

So, ideally a stage 1 and 2 ? is that all for stage 2 ? i recall seeing a 'cover' is that just aesthetics ?

weeksy,

the stainless cover is something i make. It serves one of 2 purposes, looks great :) but alos helps the rubber outer on the filter fit better and also covers up the words on the side of the filter box that state 'for off road use only '

Cheers

SO without sounding too harsh....

i don't 'need' one as such ? it's just an added bonus so to speak ?

not needed at all matey :)

From what ive read stg 1 filter replaces your standard filter and will give minimumal if no top end performance but more mid range and better off the throttle response, where all stg 2 with replaces the right hand side of the air filter box with a filter allows more air in which gives more bhp through out the rev range, more torque, better throttle repsonse, etc.

Also if your going to the track think about removing extras like pillion pegs etc that will weigh the bike down. Also once on the track you can drop the tyre pressures a bit to allow for more grip on the track.

Looks like the Stage 2 is the way forward at the moment then, maybe the stage 1 before i go as well.

i've done 100+ trackdays and raced a bit too so am OK with Track stuff in general mate :)

Right i've found what i was thnking about before

So, what's this ? Is the first one the cover and this the filter so i need BOTH of them ?

Or is the first one a filter and cover combined ?

Edit, is that the Stage 1 filter ?
