First attempt at matched inlets - *graph inside*

[jack_davey]

Had a spare set of inlets lying around, so had a quick go at port matching them for the girlfriend's 182 cup, which had RS stamped inlets as standard.

I did an RS tuner performance analyser test before and after, note that this was one the same road on the same day and the two tests were done within a couple hours of each other. So a pretty accurate test, albeit the early rev limiter cut in on the after run.

Here's the results:

Gained roughly 8bhp / 8Nm at the wheels

Thats pretty good going, normally rs stamaped inlets only see 2-3bhp gains

Cheers, I think despite the early rev limiter on the second run, you can still see the peak torque, however the peak power on the first run was at roughly 6800rpm, on the second run it was making 8bhp more (at the wheels) at roughly 6100rpm
