Unrestrictive filter setup for 330bhp

[simondavies89]

Hi, im going for more horsepower and have been told to expect around 320bhp once ive had the new engine work done. i was looking at dimensions and capable bhp stats for each size and it looks like what i currently have will be restrictive. The pipe from the air filter is 60mm i believe, will i need a larger diameter pipe or should i just stick a bigger filter on the end?

Thanks

Sorry, Clio 182 with a turbo. Just looking at improving a few things before getting the work done

I use a 75mm outlet piperX cone filter from a Cosworth RS500. Good for 500hp.

So il need to buy a larger pipe to the turbo then and then put a larger filter on? The pipes 60mm i think at the min. No point me stickin a huge filter on if the pipes ID is small or am i gettin this wrong??

What's the inlet to the turbo? 60 odd?
Get a pipe that size or similar and stick a cone filter on the end of it

I had a 60mm to 75mm 45deg silicone elbow on my megane 225 setup but now the gt2860rs turbo has a 75mm inlet so I now have a 75mm elbow.

I might have the old elbow somewhere if you're interested. It's blue by the way.

I have a gt2860rs so il need a 75mm bend, 75mm pipe and larger filter? The filters ive been looking at say a 75mm ID fitting and 200mm x 200mm is good for 320bhp so that sounds spot on?
