Fabspeed airbox added on 88 3.2

D Hanson · 08-03-2003, 09:00 AM

Quality was a little less than what I had expected, but the air box cover was ver inexpensive. The metal fasteners seemed a little flimsey, but as long as they hold, I am happy.

I am very pleased performance wise. My car feels like a completely different car. I did not expect such a dramatic improvement in accelleration. I noticed a bigger change by adding this fabspeed air box cover than the change I noticed when adding the autothority chip. Everything has now come alive with this car and it sounds better too.

BTW, GTech seems to support about a .2 change even without the need to do clutch eating launches. 3rd gear from 4,500 rpms to the red line is wild now and 4th seems stronger. Not notice too much in 5th.

Where did you pick up the airbox, cost?
TIA

Are you sure this is real? Airflow through the factory airbox is not constricted or representative of a performance limiting factor; (like the barn-door afm for example). I replaced my entire intake with an Autothority MAF / chip and wouldn't say that it changed things nearly as dramatically as you describe. Could the additional sound in the cabin be flavoring your impressions?

Not being a smart-a$$ but your results sound unrealistic for such a minor tweak.

Mike, exactly what I was thinking.

I put the Fabspeed air intake on my early 911 ('73 911E) and didn't notice any difference in performance. I did notice a MUCH better sound however and I like the way it cleans up the engine compartment. I'm not sure it was worth $175.00 but you only live once

Cut a hole in the airbox. Gives you the same sound and who is looking at your engine anyway ?

Martin3.2 · 08-03-2003, 04:14 PM

And it also saves you $175.

Martin3.2 · 08-03-2003, 04:20 PM

And a whole lotta hassle.

I understand you guys point about the increased sound sensation and I am also a bit leary of any claims to increased hp for engine mods on N/A motors. I have used cone filters on other cars in the past and not noticed any differences in accelleration.

Anyway, the G-Tech Pro seems to confirm what I am feeling. Take it or leave it, no big deal either way. Just though I would pass it on. BTW, I drove car into work today and was once again shocked how it feels like a different car.

Not sure about holes, but for only $ 175.00 why bother.

Wow....just noticed your sig line...........nice stable!

I picked up a factory airbox this winter, and cut it down so only the frame to hold the filter, and the clips remained. I used the pics of fabspeeds piece to guide my dremmel.

It's got a bit more burble at WOT, and it makes working in the engine bay a lot easier. Other than that... nothing. I even suspect it may be SLOWING down my car.

I paid $60 for the experiment, and don't really regret it. If I'd laid out the $$$ for the fabspeed part I'd be disappointed.

FYI-> Car is equipped with factory chip, factory heat X, euro pre-muffler, GHL single in dual 3" out, and a K&N filter (yeah I know, but it came with the airbox).

Wil Ferch · 08-04-2003, 09:27 AM

I too have cut away the box to end up with a "frame", mostly for maintenance access ( all 4 clips of the lid are now clearly visible, and I now have better access to right-topside valve adjustments and Koni shock adjustments.
Um...Lucky you... I can't be quite so cavalier in saying that for only $175, "why bother" doing something else?? Ahhh... 5 minutes with a Dremel got me the same thing. I guess it depends how easy the $ comes in, eh ?

I was thinking of adding this mod as well to complete my chip, cat-bypass and dual out muffler mods. If you feel you got a good bang for your buck who cares what anyone else says...did they drive your car before and after?

I mean who would know better????? All cars are different.

I think I might look to this mod next, even if only for a little more noise and space in the engine bay.

What type of air filter do you have? Stock? K&N?
