Who does short IDA manifolds?

[jamiep_jamiep]

As per title really, I'm after some but can't find anyone who sells them...

[Dave Rosique]

I have two used pair for sale, Race-Trim & no name.

~DR.

[Eric Justus]

I have got for sale...no names. They were ported for my old heads on my ghia tho. If you want them, $25

Udo sells new manifolds with flanges that allow carbs to be mounted either way.

[Udo]

Thanks Jim
they have enough material up to wedgeports 

Udo

[Jim Ratto]

Udo, do they need welding to port through a large oval shape, like Berg 871 port?
Also how much are they in US $? I am interested in a set as well.
Thanks,

[jamiep_jamiep]

Nice Udo, drop me a line with the price...

[Udo]

These are ported to GB heads , no welding needed . Price at the $-euro rate is 290 + shipping

Very cool subject! If I ever become blessed/lucky enough to score a set of 44 or 48 IDAs, I'd love to have short manifolds. I never see 'em on engines any more, these days. They worked great back then. Love that old look... especially when using an old Porsche distributor, also. GOOD STUFF.

Kaferboy, I wish you well on your venture. Please post up a pic or two when you get 'em on your engine.

The BERGS sell short IDA Manifolds. I am running a pair on my new 2275.

I suppose your engine will not run the same as with long manifolds?  Better, worse, more torque, more hp??    Can someone fill me in?

Yes I have been struggling with that question too,what is the main difference between short and long manifolds?
When you look at pic's from the "good ol'days",they used short manifolds.
Can somebody help us and explain.

If you have short manifolds you can close the rear decklid  . I tested it on a 2,1- 195 hp engine some years ago and found no difference except i had to change the jets . I made these manifolds because i was tired of welding .  They are between the short Bergs and the tall ones which are avaliable . So you have more space to the fanhousing regarding to the short ones .

Hmmm interesting subject, would it just be the amount of air able to get to the carb?

[Diederick/DVK]

i understood it does affect your engine. supposedly, tall manifolds give the engine more bottom end power due to the flow. and short manifolds would do the opposite (high end that is)

i definitely prefer short manifolds as far as looks go. i'd use them just for the mojo!

+1 for the win.

Well played, Sir.

[Jason Foster]

Udo those look real nice.
  I agree on the mojo factor too.

 I to this day kick myself for selling the untouched Deano manifolds that came with my IDA's I should of just waited longer to finish the engine but I sold them to get money for other parts. Live and learn they say.

This is a length of runner issue. The longer the runner , the more you will be tuned at lower rpm. The shorter the runner, the more it will be tuned toward the top end. It boils down to the speed of sound from the top of the intake runner to the collector. If you build something with heads , cam etc, for bottom end and put short manifolds on it, you're not going to have optimum power or driveability. And the reverse applies , as well.

If you have short manifolds you can close the rear decklid .......

with air filters!

[Udo]

If you shorten and move the right one a little you can use the air filters on big cc engines also . This was another point to get the shorter ones

Yessir! Precisely why (aside from great looks) that'll work better for what I want. I'm not interested in racing my car... just wanna have something with a lotta drivability like my other two cars. Thanks for laying out that info, John.

[Lids]

If short manifolds were good enough for Deano, then they are good enough for me.

[John Rayburn]

Mark, for what you're building, longer manifolds are what's called for.

Really? For freeway driving? I'm so confused (nothing new)... so I'm going to East Los Angeles and hit a skatepark and eat at King Taco. We'll sort this thing out during a later juncture, such that it is. I fare thee... bidwell.

Some of the short manifolds don't need any mods to fit air filters.

[Jim Ratto]

I think the VW is the only motor that has its Webers over 6" away from its cylinder head. Look at 911, any inline 4 running DCOEs, Italian V12, etc

does that tell us something?

And rain catchers!....................BTW, No name shorties,2332cc,early engine bay  = P.I.T.A. Plug changes!

You either need to be a contortionist with tiny hands and special tools or "doors" cut in the inner fender with short manifolds.  I hated mine years ago and went for the doors.... much easier!

[rick m]

Ratto,

You have a very solid point about the shorter manifolds. For street use they work great. The taller manifolds are without at doubt better for Drag Racing.
