3.2 Intake mods: Pics, Info & Good Read

Keep in mind that the article is from Feb 1991 issue of European Car.

CMW probably still does Throttle body reworking.

In retrospect I honestly think the benefit of this modification alone was minimal.

I STILL WANT TO KNOW WHERE I CAN GET ONE OF THOSE COOL CONICAL AIR FILTERS.

Somebody? Help? Please?

What's this about the rear latch on the airbox?

I get to mine just fine. Granted I don't have A/C. Still, it's a bit of a challenge. Doable though?

My arms are long and skinny, but not THAT freakish.

Despite the potentially exagerrated claims of hp, the relative difference between OE and SSI's would be about the same, right? Meaning, whether the dyno programmer used 18% or 14% drivetrain loss, the difference would still be about the same?

[RickM]

LOL, Kevin.....not TOO freakish? heh heh

I have pretty big forearms (I'm bracing for the jokes already) so there's no way I can reach with everything in place.

Matt: Here's a "kit" to convert over to a K&N filter..not a cone but similar. I love the "Rock Solid" claim on improved performance. Better be sitting (on a toilet) when you see the price.... http://www.lindseyracing.com/911eng1.htm

Seriously, I'd think Wayne has the Cone filter conversion. If not a Google search should bear some fruit.

Yes, it would be about the same. That figure would be useful if they compared it to what the car made (before the mods) on the same dyno, at least you could figure out a percentage increase. This would be sooo simple for a vendor to do that when they make a claim without supplying before and after figures my nose wrinkles.

Has anybody done a 3.2-3.6 conversion of the intake manifold? i have a picture of three bolt to two bolt adaptors which would allow the use of the 3.6 manifold.

AJUSA farms out the boring of the throttle body. Around $200 I think. You can get a cone type filter from Wayne I think.

Have looked at PP and can't find...

Anyone know where?

I want to do this on my 3.4 this winter. Last week's thread on Intake from a C2 '91 are it "bolt on" to a 930? has some pictures of these adapters. I think 964 intake runners might be a little big for a 3.2.

Try AJUSA's website. I only refer to other vendors if Pelican doesn't carry it.

Ok Matt, I pulled up Feb 96 issue of Excellence and located the the guys who made the air filter/billet mount. It's from these guys down in Jacksonville Florida called Technical Dimensions, which I believe also goes by the name broadfoot-racing. You can try to do a search on them and give them a call. This ad claims a 8 hp gain, but I venture to guess YMMV.

[CamB]

Coming in late on this, but I call ass on the 258hp too (and 270hp with fancy manifold).

I've got 270ish (245hp at the wheels) and have:

- 3.2 (short stroke)
- twin plug
- 10.5:1 comp
- fully mapped fuel and ignition
- SSIs
- individual thottle bodies
- early s cams

So I should be ahead on the cams, the twin plug and compression, and if inlet restriction is a problem, I'm ahead on the intake too.

In fact, I had Carrera injectors, and on standard fuel pressure they start to run out of duty cycle around 250hp, apparently (now I have 944T ones).

However, to back up Chris point. If the dyno correction factor (from wheels to flywheel) is 1.2x instead of 1.1x, I have 300hp.

Steve W, much thanks... Can you PM me with some chip pricing info and recommendations for my (all stock) '84?

Cone filters? Autozone now sells cone filters for the F&F crowd for around $30, along with adaptor plates that cost like $6. You might need to change the drilling slightly and dremel the opening, but it works fine. I used this setup with a 3in pvc elbow to get the filter out under the opening in the tail, have about 8k on it and am very happy. Keep in mind that all these cone filter setups whistle a little, which I don't mind but drives some people nuts.

[RickM]

Greg, Have any pics of your set-up? Sounds like a good DIY project.

I recently bought the same intake plate and the K&N cone filter from Broadfoot Racing for $90.00, shipped. The plate is like the blue one in Steve W's post except it's anodized purple.

http://www.broadfoot-racing.com/

The plate came with a tapered opening and it looks like Steve has radiused the edge over, which is a good idea - a radius will flow more air than a sharp edge. This kit also allows the use of the largest filter that will comfortably fit in the space. The one I recently got is anodized purple, which I could have done without, but it's barely noticable when installed.

My car has a Dansk euro premuffler, Dansk sport muffler (big single tip), and a Steve W. custom burned chip. I previously had a stock airbox with the entire face cut off and a K&N, and that combination yielded a very noticeable improvement in throttle response, midrange and top end power. The Broadfoot intake kit may have made another slight improvement, mainly at higher RPMs, but I did it mainly to improve access to that side of the engine.

[greglepore]

I'll take some this w/e . I don't know that there is any performance gain-I did mine simply because it comes off in about a 30 seconds if you need to work over on that side. I actually bought mine from a guy on ebay who lists them constantly for 944's-you can buy the whole setup from his website for 39.99 plus shipping.

[greglepore]

Well, have photos and tried to post, but server says their too large, even though they're under 65k. Hmmm.

[greglepore]

Ok, here we go. Didn't have time to pull from car, so not as clear as they could be. The elbow is a standard 3 in pvc street L-flared on one end, not on other. Cut off the flare, and it slides over the metal adaptor that bolts on to the afm. Chamfer the other end with a grinder and it'll go into the boot. The boot may not be well glued to the cone and may pop off, easily fixable with either 3m plastic and emblem or epoxy. Anyway, after everything is put together you need to mark the relationship of the elbow to the afm, remove afm and drill for a single screw to hold it in place. Protect the afm from drill shavings. Finally, I used a hose barb fitting (brass) from a hardware store to accept the breather from the oil tank-just drilled the hole a smidge undersized and threaded it in.

Because of clearance, this cone contacts the manifold slightly. I just made sure it was along the metal reinforcing rib. A narrower K&N style would fit better.

Again, the main reason to do this is to work on the right side of the engine all I need do is remove the afm/filter as a unit-two nuts and one electrical connector and you have total access.
