JMF Heatshield for FP Cast Manifold - Modification

[daren_p]

They are made out of aluminum and I agree that it's stupid. When I called JMFab I suggested they use a stronger material but they said it would be too expensive. Honestly I'd rather pay a few bucks more and have the piece last as opposed to have it made out of aluminum and have it seize up and then be forced to cut it and get a new one.

Maybe we should send a PM to JMFab and have them read over this thread. There are a lot of good ideas here on improving that bracket.

The added advantage of the bolt method is that you can also attach a lower heat shield to it which would be very helpful in keeping the temps away from vital components.

Tom, I think thats a good idea (to send this link). I just came across this but I will add, my heatshield origionally needed to be tightened every few days as it would always come lose. I had to remove it to tighten the mani nuts & can say, while my "main bolts" on the heat shield didn't snap they were pretty well seized & it took a long time to get them out. When I got it all apart, my front bracket was still nice & straight while the back bracket (closest to the block) was very warped (maybe even more then yours). I took some pics of the brackets & can post them up if need be. When I reinstalled, I had to first re-tap the bolts & then used some 2600 anti-seize. After this it stayed tight much longer but after several weeks, it once again has losened off.

I have several items fabbed from JM Fab & I think they are excellent products (as are most of their other items) but I have to say I'm abit dissapointed with the heatshield. I too would have to say using aluminum for the bracket (well atleat the one thats closest to the block that the bolts thread into) was a dumb move.

Interesting thread... perhaps a cast iron bracket for an additional amount could be in the works at JMFAB that we don't know about.

Yea but who the hell wants a rattling heat shield that they paid 90 bucks for....

Don't look at me, I'm just brainstorming ideas.

I know.... Im just thinking out loud.

Problem solved.

Did anyone from this thread contact JMF? Or did he swap materials himself?

 

[Boosted98gsx]

He probably saw this thread and adjusted his materials.

I would recommend getting that coated some how. Certainly doesn't look like stainless.

Isn't it hidden when it's installed? I don't have the heatshield for my mani yet, heard about the problems people were having and decided to hold off. But why would you need to have it coated if it's not visible?

You dont.



Im glad they saw this and changed their materials.
I need to contact them now and see if I can get a swap out or something.

I had to cut my damn heatshield off the brackets because it was so siezed and stripped.
That bracket is junk now.

I adapted Peepers way a LiL and switched the brackets around so the threaded bracket is in the front, then put double nuts on the cover...the hardest part is you have to notch the middle of the front bracket with a grinder to fit in the rear, round the corner off the left side of the bracket, and I made the holes in the cover a LiL bigger also.....The screws are the perfect length..

GDNF2ET, I thought about your idea but I couldn't figure out a way to get those long bolts thru? The head, JPipe, manifold was in the way?? Not to mention I couldn't get an allen key back there to tighten the bolts to secure the brackets? Good job though!!

Thanx Peepers, I wouldn't of thought of it had it not been for your rightup..

What I did was put the long screws in the bracket that was going in the rear, then twist it around the header flange counter-clockwise. You have too adjust the length that the screws stick out through the bracket to get it to spin around the flange..Once that is done, I put the other bracket on the front and twisted the screws through. When I got them as tight as I could with my fingers, I grabbed the unthreaded part of the screw with a small pair of visegrips and tightened them up..

another case of "now you know" and now I know too. So off to work I shall go, vise grips in hand

Ok, I just toasted my second in a row AC fan, a SPAL 10" low profile, and the reason is because I run a 20G/ PR recirc. O2 housing, all without a lower heat shield (yes I have the upper one mounted), and I'm really tired of there not being a lower heat shield bolt-on. I wish JNZ would make something that would either bolt on to their existing upper heat shield, or mount separately.

No one makes anything for sale, it's all custom fab...JNZ take a look this is something you guys could add to your line.


I toasted the fan because I forgot to turn it on via the cabin AC switch, and the big thermoswitch that runs it wasnt mounted directly in front of the heat source, so it didn't override and come on either. Or maybe it did, but when the fanblades hit the melting glob of fan cage sinking into it, it stopped the fan and then popped the 20A AC fan fuse.

Now its a puddle of Italian plastic goo shit, and I'm annoyed....

Sigh...

Without seeing your turbo, o2 housing, and dump I can't be sure it's an option but have you considered header wrap? That was my solution to prevent things from melting as I didn't have a turbo/o2/dump shielding option on my fp3150. I was most worried about my alternator with it being so close to the turbo exhaust outlet.

My fan near the turbo though is a push fan mounted on the front side of my a/c condensor. 10" low-profile spal fit just about perfectly on my 2g.

yeah, I was already planning on getting jet hot treatment for compressor, O2 housing- and DP is already heat tape wrapped and sprayed.

Just wanted this fan to last until after the DSM SO this weekend....

I have been running a SPAL AC fan for the past 3.5 months with no lower heatshield on my FP3052 (as like you said above, no one makes a heatshield for these either) but before I installed it this spring I had my turbine housing, SS O2 housing & downpipe all coated by a local coater. It a black high temp ceramic that goods to something like 2000-2200. They also offered a special interior coating that suposed to trap in the heat even more so I had this done on the DP & O2 (as they don't do turbine housings internally for obviious clearance issues). So far this seems to have worked for me, so hopefully getting those pieces coated will help you out as well.

Going to bring this one back. Just wanted to let everyone know, I have been running the current steel (I believe) revised bracket on my heatshield for the past month or two. I have not tightened it once & the heatshield is still nice & tight. So I would say this will no longer be an issue to worry about, for guys that are looking to pick one of these up.

Agreed. I got the new steel bracket. Much better now.

[ILLiCliPSE]

yes the new brackets for this heat shield ARE steel. I had my original aluminum ones crap out on my and strip. I got the new steel brackets and bolts for $20 for JMF.

 

[DGajre777]

Update for 2010:

Just got off the phone with Jim at JMFab, they are no longer making the steel brackets for the FP manifold heatshield since they discontinued the product 8 months ago.

He said that he's going to look around to see if he can find some laying around and to call him back in a day or two, but if he custom makes one out of steel it will probably cost as much as the heat shield.

 

[Artago]

Shitty. At this point it might be cheaper to get a metal shop to cut and weld a whole new bracket. You'd have to design it obviously.

If JMFab doesn't have any, I'm thinking about getting a thick piece of steel and bolting it under the weak aluminum piece that bends. It "should" keep it straight.
