I have a friend that has a x50 996 turbo that wants a bit more power
Y-pipe and or exhaust system
so lmk if you anything used to sell

 

Skip the Y pipe but do get an exhaust and a tune and possibly inlet pipes if it is a manual.

 

This ^.

And get a tune.

 

Exhaust
ICs
5 bar FPR
K and N

580HP.

 

I see you mention K&N, is that a better choice over BMC or is it a negligible? Is 580 at the crank, I assume?

 

I'd say negligible, I run the BMC in the 991, and frankly, they're pretty much equal.

 

Yes, sorry, at the crank - that's about the upper limit of the K24s.

 

I think the paper air filter flows well, it's pretty large. The paper cleans the air much better as well.

 

I was sold on K&N years ago when I was watching some early morning car show and the fellows were testing paper elements against the K&N cotton (?) whatever - the K&N flowed 30% better, I have never looked back. The biggest single difference is on the diesels especially with big turbos, butt dyno can notice immediately.

 

They flow better but let more through. In these cars the paper filter is big enough to not cause a restriction so why eat the extra dirt?

 

The only place I was a little worried about them was up north, where I did was them out on a quarterly basis, but, they were always clean on the inside, despite how caked up they were on the outside. The BMC that is in the 991 is similar; when I swapped it out at 25k miles, it looked like this - nothing was getting through (I have two of them, I just haven't cleaned this one yet).

 

I don't think it's worth it but suit yourself.

 

Also, at $139 for a paper element replacement, I'll buy a couple of the reusable ones and clean them.

$139 for a paper filter is insane.

 

the stock filter is fine

dont think k&n filters require oil? not good for cars with MAFs

pelican has porsche brand fitlers for $100

rockauto has a mahle one for $20..its probably the same thing.

 

I'm mafless and if rather pull them once a year and clean them versus paying that much for paper.
