My midplate troubles.

I bought a KFM mid-plate for my fox body but it's not going to work as is. I'm not sure what to do, the mid-plate would almost be into the firewall with the engine in it's current spot. Not only that but my super comp's would take out most of the mid-plate where it would mount. It would need more meat on top for the bolt tabs. Maybe I should fab some solid engine mounts to go along with the front plate? Right now I just have the front plate and a tranny mount holding the deal in place.









Here is the plate I bought and the cardboard template of what is left after I would clearance it around the headers.

sorry I spoke to soon

I've been advised not to run my tranny without something attaching it to the car other than the bellhousing bolts, even a stock rubber mount better than nothing is what was said to me. Busted trans case trying to leave the car under motion is the reason I was given. It's happened here already and from what I was told it wasn't pretty. I just wanted to spread the load around a little that's why I bought the mid plate.

No need for a trans mount, it does not need it w a front and a mid plate.

Honestly if you cant make the mid work loose the plates alltogether and run solid eng mounts and a rubber trans.....



Lots of fast cars run no trans mount w plates.... The tranny wont fall out and if the tranny cails that bad a little rubber aint holdin it place.

The three mounts will assure you a busted case if the transmount is solid. If ya gotta go find the most wore out transmount you can find and leave it loose.....

The mid plate would be a nightmare as far as I can see, the engine is so far back it would be a PITA. I ran a front plate and a rubber mount last year but the drivers side bolts in the water pump kept backing off a bit and the car had a cold water leak on that side all summer once it cooled down. This is why I wanted to beef things up a bit. As for solid mounts, the brackets on the AJE tubular k-member aren't that rugged looking to me and I'd have more trust in the front plate to be honest. I have front to back limiters now that bolt to the k-member engine brackets and the engine mount holes in the block. I think I'll just go with what I was already, I just need a new tranny mount as I'm switching from a long tailshaft Lincoln C6 to a truck version with the short tailshaft to save 10lbs. I have a stock double hump tranny x-member in the car, a truck mount is too tall and fudges my driveline angle so I'll likely build a new tranny cross-member unless I can find a mount that is shorter in height. I was looking at some on rock auto today that might work.

Never mind......  

I am sorry I just said what my Chassis builder said but what does he know he only does it for a living he should just come and ask these guys.. so I apologize for steering you wrong..

I'm confused - I didn't disagree with what you said - I just passed along what I was told - right or wrong. Is there a thread on here that doesn't turn into a pissing match????

like politics and religion-building a car has many beliefs on what should be done and how to do it.

Oh no, a ban on auto talk coming here? LOL

I hope that I didn't miss out on something...
I have no problem making a custom plate with more material where you need it.
Just give me a call and we can discuss getting that plate back here and a new custom one as needed.
Thanks,

all them fast ass MDRC cars aint gotma tranny mount, nor do the top 5 or so on the Street Outlaws list lol.

If the factory mounts are a no go then the front plate and a trsnsmount is fine, I know of atleast one car this way.

rear exit headers and a midplate on a fox dont mix...... unless you mount the midplate from the top also but tthats a good bit of fabwork to make it happen.

Keith - if I don't bother with the mid plate I'm going to keep it anyways, it would be handy for a run stand. It would be so close the fire wall I'm not sure how to make it work. I put my engine and trans in as a unit and this is where I think a mid plate could be more of a hassle then it's worth. I just put an old block and tranny in the car this afternoon so I'll have a fresh gawk at it tomorrow.

Ok
Just let me know if I can help.
Thank you,
Keith

Fact is both have been done and obviously work. You do it your way, I'll do it mine. And I GUARANTEE my way won't crack a case.

Use one.....Poly, Rubber, Solid....don't matter. The PS guys use sliders so that the bottom of the trans is supported but has the ability to move if need be. But PS cars, with their tube chassis, are much more rigid and prone to cracking stuff (like Jon was describing) with the power they make.

Yes, but it still holds the trans in place so to say. Maybe I am using the word "mount" differently.

granted the midplates are not just stuck in there there are an integral part of the chassis
