It looks brilliant! I''d love to hear it now
What is the sound like? Any improvement with performance?
Thanks, It sounds really good and different now. I noticed an improvement in performance when i fitted the 4-1 manifold and exhaust couple of weeks ago. After fitting the plenum it ive not noticed much gain in performance but i have noticed a steady consistent delivery of power/torque throughout the rev range. When you press the pedal the power is there without any fade off or holding back if that makes sense. Idle is also a constant note with the rev counter at 750rpm with the tiniest of twitches (and i mean Tiny like <10rpm).
As for the sound ill upload a video later next week after i have a RR session. It will be interesting to see what it produces with a standard unmolested engine and ecu.
Thursday I also fitted some Bilstein B4's with the eibach spring kit, replaced my lower arms for some with powerflex bushes (the old wishbones were very worn anyway), & added some new metal drop links. It felt so nice to feel a good suspension setup again! That was untill 1 of the metal droplinks decided to break after hitting a bloody pothole so think ill just stick some plastic ones back on.
