Curious who this "piston specialist" is?

I have heard that this motor is rather stout and Cobb seems to have great things to say.

Only time will tell... I'd be smitten to get 250hp/300pft @ the flywheel...

I was hoping to get 300hp 300tq with stage 3 but if 250hp and 300 tq am all good
My STI was 300whp 310wtq at stage 2. That thing was ridiculously quick, so take 600lbs away and it would be hilarious if the ST could put out that power. 250hp would be more than enough for the road.

Tried and tested by Finsport and SCC Performance, result was an overall power LOSS. Stay away.
Peak loss or no gains to be had? You may lose a few hp up top which is useless power anyways and gain in mid range torque. Do you have the dyno sheet or know where to see it? I would imagine that a manifold like this would boost your midrange power a fair amount.

Well that does not make a lot of sense if you look at the way a equal length exhaust manifold works. One thing I will say though is that the tubing diameter looks to be on the large side for a 1.6 litre engine and adding to what betterthansx said I like to see the dyno sheet.

Why would a manufacturer make a product that loses hp? and why would they sell it? I'd be interested to see some proof about these "dynos"

Exactly.

There is likely more to the story. Sometimes when a story is told people only hear what they want to hear. It is likely that there is a peak Hp loss but a good amount of mid-range gain. Which, to be honest, is where you ACTUALLY drive.

Whats wrong with that? 20ftlbs gain at 2500rpm and more gains until 4,000rpm. So it doesn't gain tol end, but really this is not the nature of this motor. I think up top, equal runner manifold loses velocity for the stock size turbo, nothing that a turbo upgrade won't fix ;)

Here you go.
Ya so exactly what I had said. Nice mid range gains. Not huge bang for your buck but its still a gain. You lose on the top end but the ONLY time you use top end is on a long straight away at a track. Mid range pulls you out of corners and drives you around town.

The old adage in the automotive industry is; buy HP drive TQ. Everyone brags about HP and yet HP is just an equation.
