Kurt, Kurt, Kurt...

Who writes this stuff?

OK, that's a little strong, and WAC is a great repository of information, but the Quad4 article that just came out this morning includes the following photo and caption:





Uh, sorry, but that's the INTAKE MANIFOLD!!! The Q4 exhaust ports are on the firewall side of the motor. Also, far from "all Quad4s" used this manifold, as many (including the W-41s) got a cast aluminum intake.

 

Ha.....good one.

 

LOL, It is the W-27 ALUMINUM exhaust header option.

 

^^^ ^^^ Bwahahahaha

 

The caption under the picture I'm looking at says,

 

So it's been changed since I posted originally. It said EXHAUST HEADER this morning.

 

By the way, even that statement is incorrect, as the top photo shows a cast aluminum intake, not a tubular one. The "all Quad4s" is not correct.

 

From he newsletter this am....

" 25 Years Ago Oldsmobile introduced the Quad 4 - a superbly modern DOHC 4 cylinder. With direct port injection, computer controls for timing and fuel delivery, it precursored all the things we take for granted in 21st Century auto engine. But it was a very radical approach at the time, and it was so good - it appeared in all of GM's cars except for Cadillac.
And it was a hot rod - with 4 into one exhaust headers and a very free flowing intake. Delivering 180 PHP from 2.3 Liters (consider, it would have produced over 350 HP in 5.0 L V8 form which was considered), the engine produced very lively performance in from the day it was produced until production ceased in 2002. An Olds only W-41 version generated 190 HP for the Olds Acheva SCX.
The Quad 4 also powered the Olds record-breaking"

 

What you have all witnessed now is one of the strong suits of the Tech section of Wild About Cars. Corrections can be made at any time. This particular one was corrected before your post here was made, Joe.
The Tech section is compiled (aka secondary) information, and as such is subject to error. But since the information on the site is not static, corrections, additions, and improvements can be made to the information there. So as time goes on, the information can, and often does improve.
Constructive criticism especially in the form of correcting information is always welcomed.


Even the cast intake is "tubular", Joe. You can pick it to death if want to.

 

Sorry, Kurt, it may be "totally tubular", but is isn't tubular. Tubing is thinwall and usually welded into an assembly. Look at the header, er intake in the lower photo. I don't think anyone would argue that those are tubes. The cast intake in the upper photo (and the one on my Q4) are definitely not made of tubes. By your definition, ANY intake manifold is "tubular".
