Finally!! cp-e breaks cover on the highly anticipated side engine mounts!!

[mlassek]

ok this is very exciting but lets get serious. what kind of time frame are we looking at here????

[08.5TRS3]

i cant wait for these .. cpe is the shiittttt, when can we look forward to gettin our hands on these

what more did you wanna know?

yeah i started on it back when randy's car was at extreme... at first i was going to do the triangle piece, but decided everything about the mounts was garbage, and it all had to be replaced. i wasn't working full time on it, other things came before it... it kept on getting pushed off. but now the hard part is done, and we can move forward.

we were working on the bushing supplier to get us some samples... i more or less knew which bushing we were going to use a month ago, and got the ball rolling on that because they are slow. we are getting the prototype parts from a laser, and i got to CNC machine out the bushing holder out of aluminum. i could have a working prototype in a couple weeks if it weren't for the slow lead time on the bushings... so if i were to guess, we are at least a month out on these.

thanks for the positive reviews guys, i do my best to get this shit done asap!

Just wondering how much thought was put into why the bolt is pointing front to back instead of side to side. And if it would even make a difference side to side. My Medieval mount is settling down pretty well, but I wonder if the bolt orientation would make much of a difference.

[mazdaj]

cant wait to put these on

see you in the spring buddy....

Right! How many times did we ask for these.

[mazdarati]

Put me down for a mount or two. Nice work CP-E

[FAUXSPD]

Just like everyone else looking to replace the transmission mount and the passenger side mount. Be nice to see what pricing and availability are.

more cp-e parts to put on the car!!

[Boother]

Awesome work! Looks to be a perfect solution for my spring birthday present

One question/concern, is there going to be a flange to the bushing or will it end at the edge of the bushing housing? The reason I ask is that under hard load, could the bushing deflect enough to allow the housing to contact the bracket.

from the pics, it looks like it sits the same way at the PTP mount.

[smakdown61]

Can you guys confirm you won't get the same "bushing walk" issue that forced ptp to recall their mounts?

Bingo, you're right. It is the same way from those CAD designs.

I bet CP-E's design will change lol.

[SSinstaller]

CP-E uses a one piece bushing that is pinned in place, I don't see why they would change anyhting..

Just wondering is PTP's one piece or two?

Thankfully no, and this has been considered for our design. After I modeled the mount in CAD, I saw that it would take at least 15° of rotation about the bushing center in order for the housing to contact the bracket (see this picture). the bracket is .281" from the housing in a natural state. the large bushing and correct durometer would limit any axial play about the bolt, causing contact with the bracket. Therefore, by design the concerns I had regarding the bushing deflection were non-issues. We always do testing on cars before they get sold, and any flaws will become apparent after two bad ass built BT speed3s do their worst to them. I expect these mounts to be able to take the abuse and still give you good ride quality. cp-e also stands behind them with a lifetime warranty against breaking.

By design, the bushing cannot walk. SSInstaller is correct, it is pinned in place where it is, similar to how the bushings are on the speed6 diff mount and speed3 rear mount. the EPDM is bonded to a metal sleeve, and then the metal sleeve is pressed into the housing and pinned with a steel pin. Additionally, the center piece in the bushing has a special contour that allows EPDM rubber to flow into cavities which lock it into place in the rubber.

We won't be changing the design of the mounts because it is correct. I will go into more detail about the bushing orientation in the next couple days, but not now (I'm under fire to get some manifold flanges done...). When I have a moment, I'll post some comments as to why our orientation is ideal.

Sorry if any of this is unclear; as i am not the best with words (like Jordan is ). If you have any more questions about the above, I'll be glad to answer them, or maybe Jordan will chime in and help me out

Cam is the man!

i didnt realize how complez your guy's shop and tools were. im very impressd.

If you could visit them some time and get a tour, you would be impressed! Their only issue is their lack of space, but with P3 in the back maybe that will get sorted out, at least a bit.

[steven88]

daaamn i didnt see this thread....i already placed an order on my medieval mounts...i would def go with cp-e fosho!

but what is the estimated time frame? are we almost there as in 2 weeks to a month? if so, i might just sell my mounts

[Trinity]

patiently waiting for these........

[SgtP]

good shit! btw thx for the help throwing in that FP cam!

[killa cam]

Thanks for the props guys! I sat down with Jordan today, and we (more him than me, thank you j dizzo) discussed the best way to explain why the mounts are oriented the way they are.

Interestingly, the few side engine mounts on the market are strikingly different solutions for the same problem. From the materials used to the bushing arrangement, they’re different in many respects. However, when people choose which engine mount they’re going to buy, they may not have the technical ability to evaluate the mounts to determine which is best for their application. Of course, an engine mount for a drag racer may not be the best choice for a daily driver. So let’s talk about side engine mounts, and I’ll explain why our mounts are designed the way they are.

There’s been a lot of discussion about our choice to orient the bushings the way we did. A lot of people will tell you that there’s one “proper” way to orient the bushings for this kind of application, but the reality is that if the mounts keep the engine in place, and are comfortable, then the mounts are a solid design.

Why does the motor move at all??? Well, Newton’s third law of motion says, “For every action there’s an equal and opposite reaction.” That applies here because we’re exerting a force on the crankshaft, which in turn pushes back on the engine. So when the engine pushes down on the crankshaft, the crankshaft pushes back up on the engine. To illustrate this point, if you fixed the motion of the crankshaft and hooked the starter up to the engine, you could run the engine by spinning the engine block around the crankshaft! So understand that the engine naturally wants to rotate around the crankshaft, and the engine mounts keeps the engine fixed in place. Otherwise the wheels would stay still and the engine would spin 

If you consider how the engine is suspended in the vehicle, it’s basically like a pendulum. There are two mounts at both sides of the top of the engine. As you can imagine, if you were to push in the bottom of the engine, it’ll swing. So we use a third mount at the bottom of the engine which eliminates the swinging motion. Simply said, the top mounts keep the engine in place, and the bottom mount keeps it from swinging.

When the engine “torques” it wants to rotate the top of the engine towards the firewall. Now, if both top bushings are arranged axially (the bolts go through the bushing laterally) then the reaction force of the engine rocking will push down and back towards the firewall. In this case the majority of the force is being used to compress the bushings. So this arrangement will work just fine in most cases.

On the other hand our driver’s side engine mount bushings face front to back not because it’s stronger per se, but because it offers us more dampening than the other orientation. First of all, compare the size of our EPDM rubber bushing to the other bushings on the market. You’ll immediately notice that ours is much much larger, and the reason is we use that extra rubber to help dampen engine movement, instead of just stopping it, which is rough on the mount itself, and the frame. The large mass of rubber provides resistance to engine movement without being harsh, but let’s look back at our swinging engine example with mount bushings rotated 90° from each other.

Now, when the engine rocks it wants to rotate around the crankshaft, which will push down and back on the bushings. That means the majority of the force is going to be along the axis of the bushing, which is long at 3.5-inches. So the engine effectively has 3.5” of rubber to compress when it torques, and we know that more rubber will provide more dampening. As you can imagine, a sheet of rubber won’t dampen a small vibration as much as a rubber block would. The same principal applies here. If the amount of material for the bushing wasn’t of concern then we’d use the smallest bushing possible. But we’ve also oriented the bushing so that it has the most dampening ability possible.

In summary, the engine mount we’re producing is designed to replace the factory Mazda mounts because they fail even at stock power levels. Our mounts are CNC machined from blocks billet aluminum so they won’t break under power, and they also feature our popular EPDM rubber bushings. So if you want the most comfortable ride and the strongest mounts (which is often times difficult to accomplish) then you’ll consider all three of our aluminum and EPDM mounts.

Ah, and one more thing before I forget. The bushing orientation is not unique to our design, and there are many other successful variations.





The important point here is that the engine mounts keep the motor in place, and that the resulting vibrations are not too obtrusive to the driver.

Hope that helps answer a few questions!

[spheed3]

Wow that's awesome work man. Thank you.

[crazyitalian041]

you own cameron. cant wait 2 try these out.

[08.5TRS3]

im definitely impatiently waiting lol

[xcoldricex]

thanks cam. also very impatiently waiting...

[wakeboarddude]

Can't wait!

[superskaterxes]

=( will there be any MS6 love? pa pa pa please??????

[steven88]

damn the medieval mounts are out of stock...wtf...i might just cancel those and just go with these

any word on when they will be released?

[killa cam]

Originally Posted by steven88 any word on when they will be released?

as soon as fucking possible... i just finished designing the welding fixtures for the robots. the prototype steel parts will be in soon, and if the bushing guy doesn't get his ass in gear, i may spin out some delrin mounts just to test fitment in a car. trust me dude, it is in my best interest to get these out ASAP. I am trying my hardest, even working at home!

[lidokrantz]

home....i thought home was at the shop.....

man , i asked for these over a year ago.....i am so glad i waited...just bought the inlet today and these(all 3 ) mounts are next...jeez with the Nano, inlet, mounts, dude ..CP-E got way more from you than they ever would of thought...this community is very proud dude....Good work man making our cars BETTER.

[Trinity]

Take all the time you need and get them done right. Quality parts are worth waiting for.

[steven88]

quality for sure! we def do not want it to turn into another ptp recall thread

[darkstarmotorsports]

no we're not. I have 4 of them sitting right here next to me.




Nice work CP-E!

[Frequentflyer]

Rear mount/side mount package deal group buy please!

[BreakTheStatic]

Bump for an update. Money in hand and waiting

[bombdotcom]

you smart guys you!

fixture for robotic welding - design done, material picked up yesterday. i will machine all fixture parts and will probably be done with that mid next week. we expect to have proto laser parts mid next week, and we will hand weld the first proto parts. bushing guy has long ass lead time, so i will probably go to metal store and buy some delrin and spin out some mock bushings for test fitment. after that it is a matter of choosing the duro that we want, program the robots, and go into full production.
