Hi, I'm thinking about buying the Fabspeed airbox for 190$. If you have one, does it reallly improve sound? Did you see any difference in HP?

Thanks!

Save yourself $190, total piece of crap!

buy the OE motorsound version from sunset or carnewal for around $150-$180

fabspeed one is junk. its plastic, and you risk the filter collapsing on itself. lots of discussion on the forum about this.

I have one on my car. Sounds cool, and looks decent but it is made of fairly thin material compared to the stock unit. I'd be willing to sell you my Fabspeed unit if your interested...for a lot less than $190.

the fabspeed thing was on my car when i bought it as well. i notice no discernible performance or sound changes after having switched to the motorsound box from the fabspeed. i was able to sell it on ebay for around $100 though...

This is Joe Fabiani at Fabspeed Motorsports USA. I designed, engineered, DYNO tested, and DE and PCA Club race tested my 993 CUP airbox coverlid. It makes +8HP at the wheels on all Porsche 993 cars. I even tested mutiple conical airinatek systems.

The best result is the Porsche 993 factory airbox with integrated velocity stack and an OPEN airbox coverlid that simply retains the stock or aftermarket airfilter.

Significant sports car sound enhancement and a significant gain in power that is NOT BS. The other option is to either cut apart a factory coverlid either the stock one or the motorsound cover.

Porsche Motorsport Germany initially developed the CUP airbox coverlids on their 964 CUP cars. Porsche AG discovered that cutting off the top of a regular production 964 airbox coverlid added +8HP to the 1990 to 1994 964 3.6 liter engine as it allowed better breathing for the engine. The power gains have been mentioned and written up by Porsche Motorsport.

With the documented power in mind and my realization that many concour and people do not want to cut apart and or gut their stock airbox coverlids ( since you can not buy a coverlid by itself one has to buy the complete airbox assembly) I designed CUP airbox coverlids for all the 911 cars from the earliest 911, 911SC, 911 Carrera 3.2, 964, and 993.

Under each and every Porssche I just mentioned the Porsche engine picked up sportscar sound and power. There was no smoke and mirrors just all sports car sound and power. Anyone can test this themselves on their car. Simply remove your airbox coverlid and go for a drive.

I own 2 Porsche 993 cars and have been a club memebre since 1986. I have a 993RS Clubsport Clone and a 993 cabriolet both of which are on my webpages. Anyone can feel freel to stop at Fabspeed and drive my cars.

Quadcammer

so, where is the dyno sheet? Was the dyno with a factory air filter?

If you took a car with a dirty stock filter, put a clean one in along with your airbox frame thingie and claim 8rwhp, thats not terribly accurate.

I bought one second hand and am very pleased with the improved sound v stock non-motorsound box. Under hard acceleration you can really hear the whoooosh. Can't say I can feel the extra power, but have no reason to question Fabspeed's integrity. No problems with the filter in a year of daily driving through all weather conditions.

Shame it is stick-on CF effect vinyl, but overall very happy with mine.

Quadcammer

also, did you have the engine cover open with a fan blowing on it while the car was dyno'ed?

Joe@Fabspeed

FYI I was going to make a injection molded airbox coverlid but the tooling cost was astronomical for 1 vehicle .......let alone 5 diffent 911 applications. REal true carbon fiber would be prohibitedly expensive as well. Thermoforming required dedicated tooling and I made the investment in digitized moulds for many Porsche cars.

I have DYNO many 993s cars with stock OEM mann airfilter paper and BMC Italy oiled cotton gause filter. +8hp Fabspeed CUP airbox over a stock 993 factory airbox coverlid with OEM stock paper filters and maybe +2HP more with a BMC F1 filter.

Now all of you understand any engine is nothing more than an airpump that breathes or takes in ambinet air and burns a stoichiometric amount of fuel to make power and then the engine has to evacuate or exhaust the spent gasses. When you have a modified engine and or are planning to make modifications it is adviseable to try to increase flow capacity/ efficiency on both the intake and exhaust sides.

Fabspeed Motorsports tried many combinations of air inateks on these cars. I PCA Club raced for many years and air inatkes were free. I had a vested interest in finding power as I am a gearhead, racer, and PCA club member and strated a business doing what I am truly passionate about.

I will look up Dyno results. On my 3.8liter 993 ANDIAL engine the Fabspeed Motorsports CUP airbox added +12HP versus stock while operating with 1.75" Fabspeed RSR headers and a dual inlet dual outlet exhaust system. Why do I mention this if your 911/964/993/996/997/GT3 is modified the gains are variable but listed on my website as the baseline gain for a STOCK vehicle.

These cars are great and can be woken up.

Funny story about finding and making power Horsepower and Torque-- my 1st PCA Clubrace was NNJR POCONO Long Course run counterclockwise in 1997. Northcouse infield turn left BIG straightaway into the bowl super high speed........chicane..........BACK on the POWER FLAT.......LONG LONG straight WOT long period.........straight line braking left into north course and etc.

My buddy Rafael Llopiz and I each had relatively new 1995 993 6 speed cars. Theye were 3 more 1996 993 cars with varioram.

UP until that race we ran stock OEM Porsche heavy restrive 993 catalytic converters with Fabspeed Supercup mufflers and a BMC F1 airfilter. Cars were fast and Porsche dealers and all shops said the factory Porsche catalytic converters and mufflers flow great and there are NO GAINS to be made by changing mufflers or catalytic converters. "You will lose power substituting factory 993 parts". This was the new car BS dont touch it syndrome.

Back to NNJR POCONO---RAF had alot of experience and I was a newby. Our cars each had newly DYNO developed Fabspeed Motorsports 993 catalytic converter bypass pipes, Supercup straight through mufflers and Fabspeed CUP airbox coverlids with BMC filters. My car was really fast a HOT ROD. I knew it from the Dyno and we showed up and all 993 were stock with certain Arizona mufflers that actually lost -9HP at the wheels.

Rafael is so FAST and has big *****..........hes up kicking GT3R cars and lightweight cars at 3065 pounds. AS I got more experience and was next to him we would lieterally and figurateivel drive up and almost SUCK the damn headlights out of all the stock 993 cars with stock cats and stock OEM airbox coverlids.

It was hillarious! I would literally run up to and buy these guys like Michael Schumacher would past back markers and we were all in the same cars and my car a 1995 993 272HP versus a Varioram 282HP.

Fabspeed having several open houses and I invite you all Ferrari Club 5/11 and Fabspeed open house to the public 5/19. Bring your 993 down and we can DYNO it.

Quadcammer

funny story about where is the dyno sheet?

Joe@Fabspeed

I have instructed my people to go and find it. why dont you come down from Clifton to our open house and be our guest.

nine9six

Quadcammer,
Why not accept the gracious invitation that was extended to you and report back to the group on your observations?

996scott

my car came with one and I have had no problems at all with it. The filter stays in place without a problem. I can't say as to the sound because I never had the OEM one on and I have the Fabspeed exhaust which sounds so dang good.

Fair dues to Joe, good replies to harsh posts!
