    New RR Results

    Got my car on the rolling road again today after fitting a sports cat and straight through back box (old one was irmscher)

    Old RR Results
    http://www.astraownersclub.com/vb/sh...t=Rolling+Road

    I gained 1.5BHP and about 2lbft of torque, about what I was expecting but was hoping for more, I put the increase down to the sports cat as there was a very noticeable difference, backbox is hard to tell as the noise can be deceiving. What is strange though is I am up 2.7bhp at the wheels, its the same dyno both times and similar time of year (within a week of each one)

    Power curce is nice and smooth same as last time. Not many cars to compare to for accuracy, there were two 1.6 16v astras, one rolleed I think 105bhp and one 98bhp, both had cat back exhausts and panel filters I believe.

    Video (Might take a few minutes to work as I just uploaded it)

    Ill upload picture of graph tomorrow.

    I am considering putting my irmscher exhaust back on, I didn't notice much of a difference when I changed to the cybox one and the results seem to prove this, it is also a terrible fit and very loud, noise isnt a big issue but the fitting is awful, it only sits on 2 of the hangers and vibrates off the bumper.
