I think that possible improvements will be highly dependent on setup. The challenge with getting more power using an aftermarket exhaust manifold is that the flow resistance of the manifold plays second fiddle to the turbine pressure. About the best that can be expected is that the turbine pressure is no less than half of the boost pressure. For a 33 psi peak boost setup like mine where the lowest turbine pressure I see at WOT is about 25 psi, an exhaust manifold that gets me down to 23 psi isn't going to get me a noticable improvement in power. Back when I was running my BBK at 28 psi tapering to 26 psi, I tested three different manifolds in one day with minimal differences in power. One was stock, one was a 1.25" tubular manifold, and the other was a 1.5" tubular manifold. The power differences were within the scatter of the virtual dyno runs (5 whp).

A lower boost tune, e.g. a 20 psi peak boost tune with a 10 psi turbine pressure might actually see more benefit because the improved efficiency of the manifold might matter more. Or alternatively, an FP Black where the restriction at the turbine is less than my BBK might see more benefit than what I saw.

 

I asked and here's a response...lol! It's like a manufacturer built a car and just showed you pics and said, you can preorder but no specs. It's better and It's a surprise! LoL! Yeah Yeah, FP's got the reputation...blah blah blah. Show me the car fax!

 

quote from FP earlier in the thread:
We don't really focus on arbitrary dyno numbers that can be inflated/deflated at a whim, we focus on stuff that can't lie.

Like back pressure testing and CFD data. In both of these test our manifold has shown to perform better in every conceivable metric. We wouldn't waste out time spending tens of thousands of dollars in tooling and R&D if it wasn't better than a stock ported manifold.

As for what turbo would benefit from this manifold, all the way from Stock to the Black would benefit from it.

 

From fp?

Yup oct 4th.. Missed that mysf

 

Problem is that their customers base everything off of dyno numbers. If you went to buy a car and they said "We don't focus on gas mileage, we focus on having a free flowing engine with low backpressure and good volumetric efficeincy" Nobody would buy it until they saw some numbers that they can compare too.

FP makes awesome products, it just seems kinda douchey to say "It's awesome, just buy it"

 

I'm sure someone will throw it on the Dynojet soon. Only takes 5 minutes to swap manifolds after car has cooled down.

 

CFD is only as good as it's inputs... garbage in garbage out. back pressure just tells you back pressure, it doesn't tell you dyno numbers. We didn't get CFD or Backpressure data... OR dyno plots. We got a picture of a part that fits on the car.

Can you prove to me that it's better than a stock ported manifold? How can you say that when you don't have ANY data. NONE. Don't try and bull**** me Jerry.

So this does not work for the 8, and does not have twin scroll?

 

what... it is twin scroll and will work with an 8...

 

easy, this was a quote from FP earlier in the thread. sorry I should have stated that

 

Steady State flow analysis likely means VERY LITTLE. But I'm an FP Fanboy and would put my money on it working better then the OEM manifold.

Would I replace a perfectly good factory manifold with one? Probably not. But if I wanted to go back to a stock frame setup or if I had a cracked stock one, I'd buy this before I picked up a used stocker.

I'd also go this way before I did a stock frame welded pipe manifold. "Stock Framed" is already a comprimise, might as well maintain the heat shields and (likely) higher reliability of a cast piece.

 

Damn if I still had an Evo I would be all over this, if it work half as good as their DSM cast manifold they have a winner.

 

I got in on the group buy and am now selling my CBRE ported manifold.

(Yes, that was a shameless plug, but I won't link it here)



We'll see how this does!

 

^^^ NO CROSSTHREADING!!!!! shameless plug
