look how cool they are
anybody using them? |
And I thought MY valve covers were hard to get off:crazy:
|
LOL
:) |
they look like a serious pain in the ass to installl and remove and they look VERY expensive.
|
puder : exactly!
|
Looks more for a California flat bottom rig than a Turkey Clubbed offshore rig! :D
|
Very interesting design...trick!

Headers (Post #1)
CMI made these. I'm sure for the right $$$$$$$$ they'd make a set for you, but why would you? The supercharged engine you proposed needs something like CMI big tubes with elbow tops. Due |
yep they are from cmi;
i dont need them but they look sexy , dont they? i dont have the pics of my current exhaust but wait i will find a similar one and post here... |

this pic is also from cmi web-site; mine is very similar to this;
|
are there any other views of the one from post #1. im just curious as to how the other tubes come around. the left bank apears to have tubes going into both collectors. looks pretty wild. :cool: :cool:
actually when i first saw it i thought it looked PhotoShoped :D |
They look like the old Can-Am 180 degree headers
|
nope ; dont have any other view

Originally posted by C_Spray Bingo. You win the cookie. By crossing the correct pipe from one bank over to the other side and arranging them sequentially in the collector, you get a pair of even-firing exhaust systems. this allows you to use the pressure pulses from each cylinder to extract the exhaust gases from the next cylinder. The concept is similar to the tuned-pipe approach on 2-strokes and has been around for a long time. Ford used them on their GT program in the 60's. It IS worth more power, but they're (obviously) tricky to make and work around. Oh - They sound AWESOME, too... |
These headers were a "Engineering Exercise" we did before our first Miami boat show display, I believe in 96 or 97. The problem at the time was the primary length needed to get the collector behind the distributor. The 180 balance of the engine did not offset the effect of the long 40" plus length.
|
They were built for the old anything goes class one engines. Now for a race engine with no dist. and our CAD experience it might work, but prepare for sticker shock.

This is a bundle of snakes:

Ford Indy V8 from late 60's/early 70's. Interesting engine, because the intake ports are in the top of the head between the camshafts, and the exhaust ports face the vee. Makes for a nice, small (but hard to make) exhaust system.

Post #20 thru #23 are great, now try to add water cooling.
|
lee, what car is that?
|
All three pics are the business end of the Ford GT-40.
Post #21 is 427 powered and #23 is the 289/302 version. The 180 exhaust system gave the engines a very unique sound. BTW, the shroud around the carb in pic 21 is to keep hot air from entering the engine. Same setup was used on the 427 Cobra and was commonly called a "turkey pan". |
I saw these headers in Miami over the weekend... They where on an engine that was showing the new chiller designed here on OSO... Wild looking in person also. They are like a 6 piece design!
|
Right on Iggy.
|
I like the exhaust on the GT-40's (the original) and the Maclaren F1 (made by BMW)

The "turkey pan" was there to deflect heat away from those large "LeMans" style fuel bowls on the holley...

180 Degree Headers
C Spray is right, this does promote better "scavenging" is the correct terminology. They also need to be equal length.
HOWEVER, this is really for higher rpm lower displacement motors.The extra power you would see on a 540 CI supercharged motor would not be worth the extra cost and amount of space this takes up. Here endeth the lesson. Wannabe in Motor City |
