is there a HP point where you should run a motor plate? my engine seems to be twisting too much lately and wondering about buying new mounts or plate it

How about solid mounts or a limiter?

I'm not sure at what HP level one is mandatory, but I'd say around 600-650 hp it's a good idea. Once you use a plate you'll never want to use stock mounts again. At your power level I do think you need one.  CHIP

I was wondering the same thing, I have seen the motor mount ears on the block broken off.
I guess you could install the motor plate with the motor sitting on the motor mounts for locating it, then remove the mounts
The ears break off usually because they went to the
solid mounts and no limiters... the ears cant take
the fore and aft movement of the engine. Even with
a motor plate it is advised that you use limiters
to control the fore and aft movement

another vote for AndyF motorplate but my 581 hemi is still using stock motor mounts with 850 hp with no problems with a torque strap.

Ari, thanks for the great pictures. i think i want to put on in. good point on the mount pulling on the cylinders too. it just seems like the engine is about to rotate around and scrape my six pack off the ground that plate looks nice and thick too

I have 2 threaded rods(1 on each side) attached to the mount ears then to the chassis, but I'm changing them this spring to a nicer set of heim ends on a rod.... mine look ugly now EDIT Some of the guys have been mounting the limiters on the 2 ears on the trans to the frame rails/chassis

I have a poly trans mount, no problems.
For the fore/aft limiter I used a Comp Engineering kit and attached one end of the rod to the trans crossmember w/ a 90* bracket and then attached the other end to the transmission case at the rear passenger's side corner just above the pan rail. CHIP

I use a set of old school elephant ears with a solid welded passenger side stock mount. The trans mount is poly. This set up is low buck,strong,and solved my external oil line clearance problem. I run 10.90-11.00 @ about 660 hp.

ok lets scale down to a super comp dragster, same deal. they are held on the front by 2 aircraft type water hose clamps and they are not held against the rear end. they do have a coupler but it's loose fit. and with all the flexing you say wouldn't that make it worse? my point is the heavy duty front motor plates are not needed imo.

If you wheel stand and run a 1/4" plate and come down
hard.... it WILL buckle.... as me. I stepped up to
a 3/8" plate with limiters
so will your oil pan and a whole bunch of other stuff

Tony, what exactly is your point? i like the heavier plate because of the 1.cutouts 2. they are made by a member here 3. they are sold by a sponsor here 4. i dont have any extra hose clamps to use as motor mounts

nothing wrong with it, I don't like the triangle cut outs on that one but it's not going to hurt anything. go for it.

I don't care for the triangles.These go with my weld wheels.I bought mine from V & V machine in Wappingers Falls NY. 
that looks much better to me, but thats just my opinion.

Hey I didn't want to horn in, but Andy has not replied. I can make your motor plate and we will "customize" it for you.(holes, triangles, solid, we can even put a pentestar in it if you want)
PM me if you are interested.
can you post pics of some plates? i would like to see some different ones

Hi, I have a 72 Charger that i'm running 10.60's with. I've done a few upgrades and should be in the 10.20's to 10.teens. I was looking at doing the motor plate upgrade as well. How can I get in touch with Andy at AE Engineering. I tried looking it up on my search engine and can't find it. Also would be interested in NHRA Mark's plate with the pentastars on it. Could you send me your contact info Mark? Please email me at raleye72@hotmail.com. Thanks Jeremy

I have solid motor mounts and poly tranny mount! I was thinking about some strap also ( side to side) cause my snout bars come in right where a motor plate would hook up to! EDIT: I just realized one of my proparts headers tubes is RIGHT under the dr side snout bar touching it keeping the engine from twisting side to side!

Sledge...That's why a lot of people attach the plate to the snout bars by welding tabs on the bars.
I like motorplates w/ NO holes in them whatsoever. The one w/ the triangles cut out would be a pain if you had a lot of stuff to mount to it...like a vacuum pump, coil, catch can, oil filter adapter, etc. Having it solid makes it much easier to position your stuff on it right where you need it.

Ray I know they dont look like stock, and cause some headaches as far as pulley alignment, alt setups. But once you go that route, and see what a easy setup it is, and working on it, you will be asking your self why you hadnt done it before.. And I make them my self. I just used some 1/4 steel and swiss cheesed them to lightning them, and give them more of a custom look. Just used a couple water pump gaskets as temp-lets and went to town. I fired up the Torch and cut the holes, they look like they were cut with a hole saw for the most.  I like doing these kind of parts my self, and it save's me a C-note too Not a great pic, and have since moved the fuel isolator but you get the idea.

I firmly believe in motor plates.. FRONT AND MIDPLATE with a POLY trans mount.. I've been told about rubber trans mounts contributing to cracked trans cases because of it's ability to FLEX... I have a World products wedge block that is somewhat "stronger" than an stock 440 wedge block,, so I am not concerned with twisting or torqueing like some previous posts... I also think there is NO NEED for a 3/8 plate if you are going to run a MIDPLATE.. A 900HP engine with a 3/8 front plate and NOTHING between the engine and trans is a CATASTROPHE waiting to happen.. ESPECIALLY with a rubber trans mount.. There is FIVE FEET or more between the FRONT MOUNT and the TRANS MOUNT !!!! NOT A GOOD IDEA.... A 600Hp engine could get away with a front plate ( Providing it's 6061 T6,or better  3/8 thick or BETTER ) and a poly trans mount,, but,, I wouldn't try it with a stroker motor !!!
I disagree with you... if you dont use a limiter
you are asking a vertical plate to carry the launch
load of about 700 lbs(static) ... take a alum plate and set
it on a pair of blocks that are at the same width
as the outer mount points... now get up on it in
the center and bounce(and I dont think you weigh
anything near the engine and trans weight) you will
see how much it bows or bends.... now sure this will
depend on how hard the car launches on how much it
will move.... also especially if you use a front and
mid plate you want some movement on the trans mount
either with a stock or poly mount... you cant acount
for chassis flex if its a solid mount... remember
the old math class... 2 points are a line but when
the 3rd point is induced its not always a straight
line and now induce chassis flex that 3rd point is
trying to move

Let me try and explain... An aluminum front plate , lets say 5/16 of 6061 T6 and a midplate made of relatively mild steel and a POLY trans mount on a 900 HP backhalved Challenger, there is NO NEED for limiter straps.. providing you have a STOUT block ( world castings) and a 727 trans with a TRUCK tailshaft housing.. with a POLY mount... Tightened up properly, it shouldn't twist up much at all.. The whole thing twisting up as a unit (including whatever the "body does") is MINIMAL ,,to say the least... There's about .004 clearance for the "basically body fit" 3/8 hold down bolts,,, and if it WAS TWISTING UP, I would lose the almost PERFECT line up when removing and reinstalling the motor plates... I'm NOT a chassis builder by any means,, I just have mine setup that way and it works FINE without any limiters... I think,, in MY SETUP,,, the limiters are a waste of time and money...

nosboy - you and Pbody are talking about 2 different things.... Raff is talking about a fore/aft limiter to prevent forward and rearward movement of the motor. I believe you are talking about limiter straps to stop the motor from torquing over side to side.

what about trans mount? regular rubber or go poly?
