ATS Manifold Heater Bracket...

Re: ATS Manifold Heater Bracket...





Jcbrown requested a picture of the heater bracket we made for the ATS manifold. Here is a small close-up. The bracket is made from some flat 1/8" stock. The original bracket on the heater tube was cut off about an inch from the tube to make a tab. The tab was then drilled for a bolt. The steel was then measured and bent to fit and a hole drilled in both ends. A little paint and voila. Hope it helps.

Is your pyro on the other than usual side to clear the bracket? Have an ATS to install on a friend's rig this weekend, this info is timely.

I've heard the temps are ~ hotter from the front 3 cylinders, that's why to drill there?

From what I have seen #6 is the first one to melt so it would make sense the the back three are hotter.

Piers' Suggestion...

No, I questioned which one to drill too, so I called Piers. He said (as 24V-DSL pointed out) that the temps were higher from the front three cylinders or at least the pyro measures hottest from the front three. Anyway, Piers suggested the front boss to drill since you would want to monitor the hottest section. I took Piers word on that (Unless I misundersood Piers response!). I don't have any empirical data to support it. Either way it still works.

But if you had the probe in the rear of the stock manifold then moved it to a hotter location on the ATS might you not see any reductions in egts with the new manifold?

Would it make you wonder if it was worth the bucks?

Or am I getting too picky here?

That's a very good question and point. I've never been one to shy away from a good aftermarket part, but with some of the requirements involved with the installation and the possibility that EGT's might not go down, I'm just not sure about this one. I would love to be convinced, because it looks cool and it does eliminate the potential shrinkage with the factory manifold. You guys convince me that this thing is worth the trouble and money.

How much does a new cylinder head cost, including labor?

I'm a bit confused on the location of the pyro, based on Piers response... ..... I had always heard the opposite of what he told you. And as AZ Cummins said, The #6 melts first, at least in the two meltdowns I've seen. Not that I'm trying to start a war here , those happen all by themselves .



I think the manifold is worth it just for the security factor alone. Especially on a 24v, where it seems to be a when, not if it will crack issue. Any reduction in EGT is just a side benefit IMO.

Actually, I really don't need that much convincing. The idea of having to drill out two of the four bolt holes in the turbo flange kinda triggered the pucker factor. I just don't understand why that should be necessary on a well made aftermarket part.

Helped install an ATS on a 12 valve today. The problems you guys speak of must apply to 24 valves as the install was easy, stock heater bracket fine.

Piers said to put the pyro probe in the rear on a 12 valve, we did. EGTs were about 50° cooler but it seemed to take longer to reach 1400° than before.



What was sort of weird was that the stock manifold bolts looked bent from shrinkage while it was installed. Either it was an optical illusion or they went straight after removal.
