Thinkin about getting my oem headers for my P1 ported. Im currently running at 326 bhp and 398nm of torque. Was wondering if their would be a decent gain from getting it done?

My current mods are:

2 1/2 inch full decat magnex exhaust
open neck downpipe
VF34
K&N panel filter
Walbro 255 fuel pump
Ecutek remap

Bin reading some other threads and most people rave about harveys ported headers. How much does he charge? It would save me loads of money over getting gt spec headers etc. Hope someone can enlighten me?

There are gains to be made with this mod. I don't know how much Harvey charges but I know there is a lot of work in doing it properly.

I have ported headers on my car and with a similar turbo I made 333bhp on a consevative map. Which RR did you use to get your figures?

I will be selling my ported headers soon as I am going twin scroll instead, if you're interested?

It was rr at powerstation. I would be interested in ur headers but not planning on any mods till after xmas. My clutch is now slipping so i need to save up for that. gotta uprate my spark plugs too. Oh well. cheers floyd.

As well as adding ultimate BHP you will get good torque gains across the whole rev range if the porting is done properly. You will also get earlier spool. Boost will increase marginally. Like Floyd has said, it is a fair bit of work to do it properly and I bought flow bench time to perfect the technique.
