355 short ram intake installed!!

Hmmm I don't think my '95 is set up like that.. I think it's like the challange cars? But what do I know..

 

sounds like you re-created the 348 intake path

 

Yep, that is the same set up as the 348, I am sure it will be an improvement.

One thing I am not sure that the 355 has is, just as duct opens up behind window on the 348 there is a fairly large drain hole in the bottom.

I got caught in a rain storm on the weekend and watching in the rear view mirror, there seems to be a heck of a lot of water that goes down there and sure would not like to hydraulic something???

 

Great job Jay! I'm glad to see they are making the racing conduit in black now, instead of only in the horrible orange color.

 

It may be worth doing this just for the sound. Tell us more Jay...

 

Another reasons why 95s are superior.

Anyway, great write up Uconn. An improvement for sure!

 

Great job! ............ that is the way all 355 GTB/GTS air intakes should be routed ............. ....................... now to remove that old squashed hose and cap the old entrance .........

 

My 95 is too.

 

Nice work Jay!!

 

Now we have Jay and goth who have 348 envy.

 

They are mad if they are not!!

 

Just started doing this mod on my car but I think I will just shorten and reconnect the stock hose.

The opening behind the window doesn't look very large but I suppose it can't be any worse than the very squished tube that was running over the radiator.

 

The size of the window scoop concerns me too. It looks to be only about half the size of those by the radiators. I'm sure on the 348 and early 355 the outlet pipe on this window scoop was round instead of a half moon shape. I think they must have squished the round pipe to make room for the new design with the long tube passing by from the radiators.

My plan (one day... if I ever get to it is to make kind of a Y-pipe out of plastic or aluminum. Then I will cut the original hose under the quarter window air inlet, shorten it slightly, and insert the pipe shown in the drawing. This will allow air from the original location and from the quarter window scoop without having to add another hose. Might allow for some extra air due to better ram effect, some cooler air and a little bit more induction "noise" for passenger and driver (very important for GTB owners Everything visible will still be original too.

eulk348, we think alike! I did something very similar to what you posted and then came inside to see your post. I cut the stock induction hose to the correct length of going over the window "half moon".

After sliding it on I noticed the hose was much bigger than that part and hung down below it so I squished the front half of the original tube to the same size as what was remaining below the "half moon". I then put 3 holes in it and zip tied them together. Basically the upper window has a straight shot into the induction tube but the lower tube is also still connected.

Pics are, drivers side of car was modified and connected. Passenger side pic shows how the ducting runs under the hole behind the window originally.

Good idea. Do you also notice some difference in sound (intake)?

 

It's great that you noticed this Ferrari compromise way back when (and did something about it!).

 

Not sure on a difference in noise, can't drive the car as the roads are all salty.

One other thing I noticed while working on the car is that it didn't get full opening of the throttle bodies when the gas pedal was floored (needed throttle cable adjustment).

Anyone have pics of that window opening area on a 2.7 car to compare if it's the same or bigger than the 5.2 cars?

 

I was helping a friend with his race car today and got a chance to take a look at the air intake on an early 2.7 355. The air intake is not blocked (as on the late cars) and has a drain passage at the bottom. I think that if I am going to do this mod I will try to get hold of the original 2.7 air inlet to make sure the flow is correct. Or try to modify the one I have to make room for the drain passage and remove the "half moon".

2.7 part nr is 64458300 and 64458200
5.2 part nr is 64989100 and 64988800

 

First off I hope that no one minds me jumping this old thread back to life.

I was also under the assumption that my 99 355 was getting it's air from the little scoop behind the window. The just the other day I was sticking my fingers in the hole (I'm always putting them in something) and realized it wasn't connected to anything.

Jay, are you still running with the mod?
I'm thinking about doing the same thing. I've also read that the top of the stock airboxes for the 5.2 are in a bad need of reshaping. Might just be another project for me.

 

Hello has anyone did this mod? I have the intake ducts from the 95 and trying to install it on my 98 but the body shop can't figure out how to remove and replace without damaging anything

 

Fwiw I had to return my 99 to stock configuration. With the intakes connected to the window corners the engine would surge under steady throttle in crosswind conditions. (I think air was flowing in one window and out the other messing up the single maf output).

That happening is what also made me think the stock 2.7 induction with separate air boxes likely work better than an aftermarket common air box.
