Headers?
Wondering if worth changing headers, and if so what do people recommend. Sure I saw somewhere can gain up to 25 bhp?
Just curious really cheers |
Depending on what BHP you want you could just port the original headers
|
Not really got a figure in mind, but was wondering on benefits etc, at what point do they need doing/changing or not as the case maybe. I mean will it be a gain regardless or could it cause loss of power/torque if not required
|
Benefits would be an earlier spool up,better pick up but I would say the actual bhp/torque gains wouldn't be huge but the actual driveability would improve.
|
What car / model / mods have you got ?

Uk 2000 turbo
Panel filter res del Rcm fuel pump Rcm sportscat down pipe Magnex 2.5pipe and back box Fuel lab Afp hybrid td04 V7 Sti tmic with y pipe etc Ecuteked (JGM) Think that's everything power wise |
The AFP turbo can flow quite a bit of air, matching the headers and up-pipe to the turbo should improve spool and torque.
e-mail Andy and see what he suggests. Shaun |
i thought tubular headers made spool worse and improved top end
|
Tubular are only needed around the 400/450 mark, ported are good up to then, but always match the up-pipe to the turbo!
|
Asa above. Mine runs tubular with a Harvey trick up-pipe, now available from ASPerformance.
It spools early and pulls right up to the redline. Around 400/400. |
