Hi Guys,
I am contemplating a few choice upgrades for the DC5, the car was remapped with KPro, a CAI prior to purchase and orignally had a 2.5" BC exhaust, now back to OEM. I need to hook up my AF Gauge to see what change the OEM exhaust has made to the AF ratios'.
The previous owners dyno shows 200whp, and a flywheel power of 239, make of that what you will. The butt dyno does show a big improvement to the mid range compared with my previous DC5 and it does feel reasonably good, however due to the big surge in torque in the midrange it does feel like the torque drops off to abruptly at high RPM's and the dyno print out does show this. I am looking for a bit more top end power. I am considering an RBC and possibly a new header with decat (but with the option of fitting a CAT for MOT purposes).
Does anybody have any experience with before and after with the RBC and did you notice the difference? I have seen some dyno's where it made a 5hp difference up top and others with 18hp difference, both Kpro'd before and after to ensure the difference was just the manifold change.
What are peoples experiences with the RBC? Did it make the engine carry more torque up top?
Cheers!
