Keith Eckert Manifold Headers
 

Does anyone know if the Keith Eckert Aluminum Manifold Headers have the same rise and dimensions as stock Gil exhaust manifolds?

Also, which Corsa Silent choice system is best for use with these headers or does the boat hull make the difference?

These are going into a 25' Active Thunder

Thanks,

Kirk

anyone? Bueller? Bueller?

I do believe KE's housing is higher at its tallest point and I believe they are taller than the Gill. They are 3.75" taller than a std Merc cast iron 4 bolt riser system and .120" narrower. On a tall deck w/Chev cast iron heads the KE package is 31.79" wide, std deck is 31.48". Possibly you can measure your current width and compare. Can't help on tail pipe anlgle of Gill. KE's flange is kicked down 10 degree as compared to rear face of block. Center line of exh flange is 15.8" up from c/l of crank on a tall deck w/Chev cast iron heads. Maybe someone can chime in with some more details for you. Thay are a great performing pipe! Good luck.

I had the KE headers on my last boat. Sounded totally awesome. I doubt that the silent choice will work, who needs it anyway, it just robs power from you!

Silent choice doesn't work. Make up one piece tailpipes and go out the transom and run some CMI's or ? on the end of the tailpipe. I can show you how to mock up a tailpipe rather easily. You can have the guys that did KE's tailpipe flanges weld you up some tailpipes for a pretty reasonable price. Give Performance Stainless a call at 920-739-9899.

Here is a pic of the autocad drawing I did to begin fitting My KEs in. It is kind of hard to read. If you have autocad I could email you the file.

Actually you can probably refer to KE Power products's web site for dimensions and then give Gill a call. I am sure they would have comparative numbers for overall package width and height relative to crank centerlines.

Here is work in progress. Having two areas of interference, one is the bottom head bolts and the other is the front of the water plumbing at the alternator and fuel seperator. Tailpipes were modified from some long leftovers innovation marine had lying around.

Dave

BlueThunder/ looks like the alternator will have to be lowered. Below is a pic of KE's bracket which locates it down lower. You need to work out an adjustment link on the bottom. I'll show another pic following. Can you relocate the seperator off the engine or use a braket which bolts up to the front of the head? If you head bolt is interfering it can be fixed by touching up the high spot with a grinder or taking a bit off the casting. If they do interfere it is a minor amount I would think.

Bob, not to change the subject but will my Stainless marine "dry" setup be ok with my new injuns?Someone told me when you get over 512 cubes i need Stellings or Eickerts exhaust?

Looking good there Dave.

John, you would probably wake the motors up a little in mid range and definetly pick up hp, especially above 5000. But is it really worth the expense. Your exhaust isn't that old and I think your motors are on a 31 or 32 inch center which makes things a little tight. Didn't Ike look into doing some other exhaust and the Stainless was about the narrowest? If ya need more.....get blown!

Thanks Bob, i dont need more power just making sure those puppies will breathe ok.As far as getting blown thats none of your business.:D

Can't use KE's with a centrifugal blower.

Mcollinstn you are definetly correct there definetly isn't much room for a compressor in front of the exhaust log. Actually in this case, how many Apache's have you seen with a procharger? Warpaint would be no different....up thru the hatch baby!

Thanks for the ideas Bob. I was planning to plumb in a 45* elbow to kick the front water hookup out but will see what moving the alt. looks like. I suspect with my closed cooling it will be tough.

Dave

I'm runnning Corsa Captains Call on my Eickerts. Just give Corsa a call, and they'll sort you out. Bob's right, too - the dimensional data is on Eickerts web site.

Eickert makes a tee kit that you can fit to feed the water in between the first and second cylinders. Works neat.

Can't be, that would be too easy.... I'll check into it C-spray, thanks for the tip. ;)
