Hi,

I've just fitted a set of headers to my car and apart from the obvious difference in noise there seems to be a huge gain in torque but the point where it reaches full boost has gone up from 3500 to nearer 4000. Is this expected??

Spec of my car is:
MY99
3 inch de cat full system
New age TMIC
TD05 with front entry
Induction mods
and equal length headers

Any advice appricated.

Thanks
Paul.

 

exactly what i found on a P1 still runing a standard VF28. Spool noticeably later, but a bigger hit of torque.

A lot depends on the header/uppipe diameter, for smallish turbos producing less than 350 BHP I think you will struggle to beat a set of ported standard headers for all round driveability. Over this time to start thinking about tubulars.

What make headers/uppipe do you have on?

 

Cheap OBX style ebay ones. look exactly the same, same diameters and joints but they were a complete biatch to fit and now the turbo sits a little rotated.

 

Send your o.e ones off to Harvey to have them ported.

By the time they come back the OBX will probably be falling to bits anyway!

 

Oh... Where abouts do they break??

 

PD - Let me know if you want the cast ones ported nicely

 

Will do, would just hope the ones I have on there at the mo last as it fookin flies!! will call you soon.....before it breaks
