P&L Header prototype - Page 19 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

P&L Motorsports · 05-06-2013, 05:40 PM

The V-Band is just in the connection to the downpipe portion of the header:

The flange that connects to the header to the overpipe is a standard flat 2 bolt flange. Hope this helps.

BEFORE AND AFTER HEADER BELOW.

I will admit I like how the Visconti tune actually RAISES TQ where the valley was.

I think the next time Jorge tunes this he will build upon this tune with more midrange.

No complaints here though as I was away for 2 days and just came back from not driving it for 2 days and WOW. The midrange is sooooo much better with the header.

Again...stock BRZ's make a 140WHP on this dyno at IAG performance.

I was about to ask for high-res pictures on Facebook, thanks Myles.

@StormTrooper Psst! I saw you asking about pump dynos and sound! RaceComp's dynos are up (third party) on pump gas so you don't need to take my word for it. More sound recording coming.

Since I'm not that experienced at reading dyno graphs. Pretty much the P&L header eliminates the tq dip and provides a nice smooth power delivery?

On it's own it adds power in the TQ dip, and up top.. When paired with a tune, it will destroy it.

Cheers for that, looking forward to your outside video of the complete P&L system ;D

one would think that a CF driveshaft AND lightweight flywheel should make some extra power as its 28 lbs of rotational mass being taken away.

Something tells me it will be felt as more "responsive" at changing RPM than an actual power increase.... none the less excited to experience that next !

Sorry to quote with the graphs on it, but are these results (before and after) showing with a tune for the header as well, or just the addition of the header?

I'm thinking I might just throw a header and downpipe on and I would love to know how much I can get as a result

And since you've got it... Any effect on MPGs?

Nardi330 · 05-08-2013, 07:39 AM

I'd think it is Visconti tuned.
