PH1 172 Sport
Well as per the group buy that’s just taken place on AngelWorks Matched inlets I decided I would try and be scientific and get a Performance graph comparison from my RSTuner.
Current Mods:
K-Tec Stealth
RSTuner 98Ron Remap
Espace V6 Airbox
What I’ve added to the car is:
AW Matched inlets
PTFE Gaskets
Cold air feed to grill under headlight
I wanted the performance analyser results to be as accurate as possible so I calculated the total weight with me and a full tank of fuel in the car to be roughly 1200Kg.
(Though the weight will affect the total power and torque figures calculated by RSTuner, providing I do before and after runs with the car at the same weight then the comparison should be reasonably accurate)
I did the before run this morning with the outside temperature at 12C and the after run this evening when air temperature was the same. I used a flat smooth piece of road and there was almost no wind today which improves the accuracy of the results.
Before I had got the graph from the RSTuner I could tell the inlets had made a big difference. Power and torque delivery was much smoother and torque was much more plentiful throughout the range.
Here’s the before and after graph.
Pink/Blue - Before
Green/Red - After
Though the figures produced may not be accurate (I think there are a tad optimistic) the results serve there purpose as a comparrison.
As you can see there are massive improvements throughout the rev range and the torque curve has smoothed out quite nicely. (Ignore the random peak that RStuner has produced at the begining of the 'before' performance run).
My inlets were quite bad but the improvements have amazed me and I would definately recommend this modification to anybody, even more so if you have a PH1. Very happy!!
