I think I will wait until the price drops. I really like this manifold, but I cant justify spending almost 2x more than the dsm version(which is frequently had for $200 when they run sales). I understand our cars are twin scroll, but i don't think the price difference is justified.

 

Your paying for product development and everything else to make this work. Yes the price will probably drop over some years from now but that's how companies make their money back from all the R&D they put into something.

 

I want one of these! I think I'll have to wait a bit longer and get my fp green and this at the same time!

 

After a week of driving I can say this manifold is a definite improvement. I am not sure how much a oem heavily ported manifold feels but this is really much more flow in spool and driving characteristics even more so driving on the highway. I decided to jump toward another FP part and it probably wont make any power but the response of a Flow Advancement Port cover should be interesting to see.

So the next step is the FP cast + FP FAP cover + intake manifold (heavly ported or aftermarket) to see how close we can get to 400 on 93oct petrol.

 

sub'd for more results. Id really like to know how the spool compares to stock.

Mine is supposed to get delivered today. Lets hope I make it home before the UPS man!

I wont have any results until April some time and they will be self-tuned VD results.

 

It may not show as much on the dyno graphs but spool is noticeably faster and power delivery is much more linear. Less boost car and more larger displacement NA




My FP anti-surge will be in this weekend so lets see how that pans out and then get some more dyno data.

 

don't larger runners typically equate to slower spool?

 

Not necessarily... my graph appears very similar to the oem manifold. The factors of exhaust pulse volume and the VE of the motor come into play as well. The spool characteristics are in my impression no slower than oem in feel or performance.


The change in runner size is more obvious but the entry angle and runner length is much better than oem that takes advantage of the exhaust pulse width and VE of the overall motor.


With that line of thinking flipping to the other side of the motor an aftermarket intake manifold would destroy the VE of the motor and ultimately slow spool (which in several cases does i.e. those massive drag intake manifolds aimed at power to the right of the graph) versus an attempt to increase efficiency with many of the ported oem options or skunk manifold improvements. The point of that is if you change any aspect of an air pump to an extreme it will deteriorate the operating efficiency of the pump.


The bad thing about evos is its so easy to make the car and engine worse that you have to really be careful and be very clear what your trying to do with the car.



N.B. I am not saying you are wrong or I am right but I want to express that I don't think it slowed spool and why.

 

From my experience many, many years ago swapping a SBR cast mani on a 2g DSM- I'd say, YES, absolutely.

 

I was really conceding this, but after speaking to someone at FP, I changed my mind. The person on the phone told me that this won't make any difference on a stock turbo "a waste of money", you need a big turbo to see any HP gains, FP Red, Black and up. Plus it's it's about $100-overpriced IMO.

 

Just goes to show we won't lie to you to sell you something.

The manifold was designed to be ran with one of our larger turbochargers and no testing was done with a stock turbo. That being said some people may seem some gains if the existing manifold is restrictive but the majority of stock turbo guys will not see a noticeable difference in power/response.

As far as the price show me another manifold that will perform like ours, is not prone to cracking, and will fit the factory heat shield for $400.

Thanks for being honest

For my stock turbo, my self ported OEM, much less than $400

 

they were trying to talk you into buying a turbo not talking you out of a manifold

 

Exactly how I see it, it's cheap....


Why keep bashing a vendor who is still supporting these old as dirt **** buckets?

 

What's the availability of this manifold?
