Clio 172 PH2
I did the inlet port on my 172 phase 2 on Monday. The lower inlet wasn't bad at all but smoother and the upper was ported as well as the throttle body opening.
I did pre and post dyno runs unfortunately quite a few hours between and i changed gearbox fluid, nevertheless it gained 5BHP and similar torque, the operator even had all correction factors the same. My car has full exhaust system decatted, (possibly different manifold) and custom made air filter, box, feed from bottom grill and velocity stack.
Not as big difference as led to believe but never mind, i accidentally binned the one that showed the most power but i was only ~1BHP more so i just included this one.
Thanks
