..::PSI::.. - The PSI G80 G82 Midpipe Dyno Numbers

BIMMERPOST
     Featured on BIMMERPOST.com
Many people raised the question on whether or not our PSI G80 G82 midpipe would add horsepower. We finally were able to get it onto the dyno and answer that question!

Its hard to tell from the graph overlay. Can you post a graph close up with just 2 pulls? It looks like it behaves a little different at low rpm

Or the vendor is just trying to lure members into watching their video because they know posting just the graph wonít yield them the sales they want. Who knows

Perhaps, but I didn't watch the video, either. I skipped to the very end where they talked about the gains. Took me all of 15 seconds.

Same actually, but you got my point. 10 minutes for a five second result. 14hp for $1700 pre-installation. What value!

Oh, I absolutely get where you're coming from and don't disagree. But for most of the people ponying up the money for the new M3/M4, that's chump change.

Maybe until you realize it's a first to market premium price. Give it 6 months and it will cost much less.

The real benefit of this video for me is the nice stock numbers the car is making.

Looks very well built - looking forward to seeing these on the West Coast.

This graph is so close with no real increase you'd expect to see up top with extra flow... I dunno do it for the sound not the power.

Thatís just the scaling and overlay. If they zoomed in, it would look bigger (itís 10-14whp)

On a car already this fast, I doubt that itís noticeable though.

I dunno, the higher numbers are from them revving it to 7k, stock runs go up to 6500... Snake oil to me.

Are we sure it's 14whp? I see a lot of noise on that graph to be able to tell.
