hmmm.....interesting. But havent some people mentioned that it would pretty much "useless" especially for a turbocharged car or something like that? i saw some numbers 4-8 hk. This is possibly the performance gains that they expect from this system. Thats not too bad

Damn, BSR is stepping it up. First the DP and now this. Awesome find.

Plus-Side to cone filter systems - they look and sound cool. Occasionally, they even improve performance if they are particuarly well designed.

Minus-Side to these systems - most are not very well designed, and rely on the filter-material alone for most of the performance gain. You could get all or most of that gain with a drop-in element.

I have a cone intake system on my '86 SVO (2.3l intercooled turbo, 205hp at 5000rpm stock). It has all the features of a very well designed system:

- High quality cone filter (K&N) with data to back-up their low restriction element claims.
- The airbox is fully and tightly sealed; air can enter ONLY through the cold air duct, and not through various pathways from the hot engine compartment. This should be true even when the car is NOT MOVING. If you can see the filter with the hood open, it had better have a very good seal system to keep out hot underhood air.
- The airbox and inlet tube is constructed of thick, insulating plastic... not metal or thin plastic that conducts more heat into the airbox.
- the cone filter actually has a larger surface area than the stock unit it replaces.
- It has been dyno tested and shown to improve performance WITH THE HOOD OF THE CAR CLOSED, and NO LARGE FAN simulating the car moving at high speed. This is the situation that imposes the greatest demands on a system to deliver the coldest air available, whether at a full stop or at speed. Alas, this is not how many manufacturers tests (or magazine tests) are done, and an open-hood test boosts the performance numbers. So I then performed this test on my own to see if it actually did the job as advertised.

Now on my SVO, the stock airbox was really a poor design, so I got a substantial improvement (6%, about 12hp, and almost all the improvement above 4500rpm). Heck, just removing one screen in the airpath got me a 1% improvement, with the old airbox. But this is a '86 design, and our cars are just a wee bit more sophisticated than that.

Bottom line - many of these systems are no better than stock with an improved drop-in filter, and some are even worse. They all SOUND faster, they all SOUND like the turbo lag is less, but that loud whooshing sound has a huge impact on the drivers judgement. Yea, on me too! So be smart, and do it right. Only a dyno test will tell you for sure. Everything else is just marketing.

I'm fairly confident that the gains BSR claims with its products are genuine (based on my own dyno testing of the PPC). But I agree with Red, how much is that an improvement over the Sports filter in the drop in box? A range of 4 - 8hp is a bit wide, ie 8 hp is a 200% improvemnt on 4hp. I suppose it depends on the testing environment as Red pointed out.

Maybe a fuel pressure regulator.

The intake systems looks good but how can that be worth $257?

I also want to know what they do with the hose that goes back into the top of the stock air box at the front.

Anyone know what this hose is for?

I guess you heard this straight from BSR simon... you all seem pretty close. Keep SC up on the news with BSR for us...

Saab newbie here...04 9-3 SS, no mods yet.

I am trying to get a handle on all the possible mods and have one related to intake. The stock system seems fairly adequate for cold air intake as-is. Has anyone modified/replaced the stock "air horn"/intake inlet (hidden behind the small grille on the pass. side)? I have started looking for areas to improve and noticed that the horn is turned upward and inward. One obvious reason is to reduce water and debris from entering the air intake. I was wondering if a modified ram air, by designing an out turned horn that pulls air from the small grille, i.e. dedicate the small grille for ram air would be worth while...or perhaps the stock design is such that a small mod in that department would be insignificant. I would envision doing this with at least a PPC and filter upgrade.

Thanks in advance.

Yes they are Malpassi Fuel Pressure Regulators.

It's two weeks time for the last 3 months now...... :roll:
Not your fault of course,but.....

Is the dp going to be available the same time with the cat-back exhaust????

Ummmm.... yes I know. I don't know about the downpipe I haven't asked.

Please do me a favour and ask...... :D
I would like to buy the whole thing together..PPC+dp+cat/back+aero=??hp...???torque.....

I bet it would be around 260HP, as a guess.

Keep us posted.... :wink:

p.s.Do you hapen to know if the stage 3 BSR would be a dp/catback/upgraded ppc????
This is just a personal guess,looking at the stage 3 for the previous 9-3....
If so,it is worth waiting for.... :wink:

Anyone? I'm itchin' to try one out and I can't make my own because the damn MAF is on the tube from the airbox.
