Haisley Machine Exhaust Manifold

[Jim Fulmer]

I saw a pic a while back of Exhaust Manifold's that Haisley's were having made, at that time they had a C/R and a 24V I think and were working on a 12V! Anyone have more info about them and/or prices?

Bump... ... . anyone have info?

Hey Jim,



Which manifold are we talking about. My laptop is down with most of my archived files. But, I still have quite a few on my new desktop. I'll dig through them and look for something. But, I need a few chriteria.



What did it look like? Do you recall anything about it?



Also, I don't know if I ever showed you my tubular manifold. Pretty close to equal length piping and BIG. I'll dig up a pic of it for you.

I am guessing he is talking about the equal length header pipe. I got an email a few months back about them.

 

[Jim Fulmer]

Yep that is it! The header, I was just thinking and wondering if anyone did any R&D and what the cost was. Hate to call them but I may!

Why don't people use headers more often in this application? Equal length would be the way to go if you have room. I think it would help you guys making good power. I guess with the turbo hanging on the end of the exhaust and 6 pipes it is hard to make one last. Does anyone extrude hone the exhaust manifold for better flow? Jim have you got your truck running yet?

I'm surprised that none of big diesel performance parts companies don't offer an equal length header. They increase spool up time dramatically!

 

[zstroken]

They increase spool up time dramatically!

Can that be verified?? There is heat energy lost do to the more exposed service area, as well as you have increased the volume you have to pressurize to actually start to move the turbine. I would think they would flow better, and for huge CFM turbo systems there could be some advantage.

My though is to either get one of these or equivalent. The other option is to buy another manifold in pieces and send it to my head porter for allot of work. I like that idea of extrude honing one!



Yes it's running and doing fine, that was my new years resolution as I got it running, cooled down, retorqued and back together ready to roll on new years eve at 11:40pm. Put 500 miles on it and did another retorque/valve run. Runs good, and I've tested it to death since then with both sets of injectors, bottle/no bottle and have it nailed. The EDM's and that little bottle shot is very ugly on power.

On my eagle talon and grand national, the spool up times were cut in half when I switched from stock cast turbo manifolds to equal length turbo headers. Sure you will lose some heat energy (ceramic coating helps a lot), but you more than make up for it with the exhaust gas velocity as long as the pipes aren't too big in diameter. Also the turbos spool up 200rpm sooner. This is all provided everything is the right size, because it won't work right if it's not. If you use piping that is too large in diameter, your turbo will spool worse than it did to begin with.

 

[zstroken]

The pictures I have seen there looks that length has been added, I imagine on the top end it will help tremendously, just curious on spool up.

 

[CanadianCarGuy]

With the added length and the right size piping, that should increase the speed of the exhaust gases exiting the manifold. This increased flow of the exhaust gases should spool the turbo with less energy than a cast manifold making it spool faster and sooner.

I wonder how well Timo's header is working https://www.turbodieselregister.com/forums/showthread.php?t=66674&page=11&pp=15

Jim,



We tried that and there is virtually no gain..... Save the $$ for something that works.



On another note, got the package. THANKS!

Glad someone posted about gains or not on the extrude honing. It was like $800+ for a manifold and turbine housing.
