Pfadt Race Engineering releases new Camaro V8 Engine Mounts

Pfadt Race Engineering releases new Camaro V8 Engine Mounts



At Pfadt, we believe in engineering-driven products that provide solutions to common limitations of performance cars. As a result of this, I wanted start a thread regarding the launch of our new Camaro V8 Engine Mount Kit, which upholds this ideal in every way. My intentions are to give everyone a brief overview, and highlight the DIY aspect of this important upgrade, with comprehensive install instructions.

Our new Camaro Engine Mount kit is certainly a must for all of you who currently have, or plan on having, power adders for your 5th-gen Camaro. Just like in a suspension, soft rubber-based mounting solutions can wear out quickly, lose their effectiveness under load, and lead to problems when upgrading other components on your Camaro. Engine isolation is no exception. This is often overlooked when building a powertrain, because it is commonly a “secondary” consideration.

It is no longer a problem lacking a complete solution, however, because we are currently shipping sets of our new Camaro V8 Engine Mount kit. The kit consists of a 6061 T6 aluminum upper component (with an anodized finish), a zinc plated steel lower component, graphite-impregnated polyurethane hat bushings, and all hardware necessary for installation on both sides. This kit will give you the engine restraint that your Camaro is desperately in need of. And as you will see below, it is incredibly easy for customers of all experience levels to install.

As always, please do not hesitate to contact us if you want more information, or are in need of clarification on installation.




Camaro V8 Engine Mount Installation

Tools Needed:

3/8" drive ratchet
24" long 3/8" extension
torque wrench
15mm socket
18mm deep socket
3/8" drive universal
screw jack

This procedure is best performed on a vehicle lift, however it is possible to install these mounts using a floor jack and jack stands.

The pictures below are to show the stock mount (black rubber part), with the OEM pedestal (silver component above the black mount), and its relation to the engine and front subframe.




And this picture is to illustrate exactly which component we are replacing.




Removal:

Open hood and using a long extension on a 3/8 ratchet with a swivel, remove the upper engine mount nuts on both sides of the engine (18mm hex)





Raise the car on the lift (or lift the car and safely support on jack stands). If using jack stands, it will be necessary to remove the front tires.

Using the 18mm socket, remove the nuts from the lower stud of the engine mounts.

Using the screw jack and a protective block of wood, raise the engine off of the engine mounts by lifting on a structural portion of the oil pan. Use care to not damage the cast aluminum oil pan. The upward travel of the engine will be limited by the exhaust contacting the underside of the body. Stop when contact occurs, you will get the extra room required by removing the engine mount pedestals from the engine block.



Using the 15mm socket and universal on a long extension, remove the four bolts holding the engine mount pedestals to the engine block on each side.





One at a time move the pedestals out of the way enough to remove the stock engine mounts.

Installation:

Install the Pfadt engine mounts in place of the stock mount being sure to orient the mounts correctly. The tab on the lower steel portion of the mount will engage a slot in the Camaro subframe.





Re-install the pedestals to the engine block using the original bolts. Torque bolts to 37 lb-ft


Align the upper studs on the Pfadt engine mounts with the holes in the pedestals and carefully lower the engine down onto the mounts.



Using the crush nuts from the factory mounts, start the nuts on the studs of the Pfadt mounts (upper and lower). Torque the lower nuts to 37 lb-ft





Lower the car to the ground. Using the long extension again, torque the upper engine mount nuts to 37 lb-ft.

Currently, we do not have them available, but most likely we will have them ready later in 2010. We do, however, have our differential mounts available currently, and we believe that is a more important upgrade for customers right now.

We inventory these products and these mounts in particular for a while now, they have been very popular among my track racers, and 500+ horsepower customers. Once you drive the car with stock mounts, and then drive our car with Pfadts engine mounts, its an easy sell.

Regards

It doesn't look very "Beefy".

Along those lines, wonder why it wasn't designed as a one piece unit? Adjustibilty isn't a must and rigidity would be improved.

Hi MadMav,

What we found out in doing the structural analysis of this product, is that it actually is sufficiently "strong" or "beefy" (whichever you choose) for the application. I have posted some FEA results below. These are plots of FoS (Factor of Safety) for both the upper aluminum component, and the lower steel component. The loading that was applied for these cases were "worst case" scenarios of simultaneous 1500 ft*lbs of torque, engine mass, 1.2g cornering force and 1.75g braking/acceleration force. You will see in the results below that the minimum Factor of Safety that we saw with this simultaneous loading was 1.8 which occurs in the steel lower bracket.

Let me know if you have any further questions about these. We are here to help!

Thank you.

Very nice data sir!

You say that the miniumum FoS is the lower steel brackets( I would like to see them have a thicker steel, but what about the mounting bolts? Upper and lower, and the joining bolt? How much rubber is being used? Or is it poly? What is the breakdown rate for that material? Thanks,

Mav

Hi again MadMav,

Well, to start with, take a look at photo I posted below, it is an exploded view of one side of the Engine Mount Kit assembly. This may clarify future questions.



No, this is not a solid mount, you can see you are correct when assuming that the polyurethane bushings in the kit are being used to isolate the connection between the top and bottom main components. The bushings are the black "hat-like" pieces being shown to the left and right of the orange upper component.

These are a 'street-able' solution for firming up your powertrain and holding it in place better. We could certainly make a 1 piece unit (and you could install it just fine), but the car would buzz and vibrate like mad. Good for a race car maybe, but not for street use.

The FoS in the lower is nearly identical to the upper (certainly within the tolerances of the analysis). When we did the design, we saw that increasing the thickness of the steel bracket beyond .125", did not change the FoS in the lower bracket portion because the limit was the contact force against the frame section. The strength of the fasteners (OEM and the ones we provide) exceeds the strength of the other components in these mounts.

The poly we use is a 70D and the bushings are the same parts that we have used in our Corvette engine mounts for many years. They do not degrade in any meaningful way.

Hope this clears some stuff up about the design. Thanks for inquiring!

Very impressed with your answers and attitude! Thank you sir. I'm positive you guys are much smarter than I, and I'm going to have to say that you have done your homework and have the data and facts to back that up.

Very pleased, and thank you again. What is the weight on these vs. the factory ones? Probably a slight weight savings as well.

No worries, MadMav, like I said we are here to inform and help!

FYI a set of OEM Camaro V8 engine mounts weighs in at 7.1lbs and a set of our Pfadt mounts tips the scale at 3.3lbs. Good point worth mentioning, thanks for bringing it up!

Aaron, thanks for the write-up, any chance you may do a similar type write-up on the rear diff mounts as well. Have been conversing with Brandon at IPS the past couple days and the engine mounts and rear diff mounts are on my DIY list.

You're welcome for the write up, we are glad to be providing them.

In regards to the rear diff bushing install instructions, I will make it a point to post them in this thread when they are ready. Look for these in the next week or two. Its a priority to make sure customers are clear on install procedures, so thank you for asking about them!

Hi robertway,

We read you loud and clear We very much appreciate your patience (along with many others') while we make sure to dot all of our "I's" and cross all of our "T's" for this Camaro coilover rollout. It is really a great product that unfortunately requires an appropriate amount of time to prepare for an effective product launch. Thanks again.

No problem Aaron, couldn't resist the opportunity to poke you guys. I'd rather wait for all the "I" dotting and "T" crossing to be complete than have something rushed out there just to bring it to market. With that in mind, any target date for the full set of suspension bushings. If that date isn't too far out I may just wait to do the sway/coilover/engine mount/rear diff bushings/suspension bushings all at once.

As an aside, to anyone that just read this last line, I am not saying anyone else has rushed something to market so please don't turn this into a pissing match.

Hey folks, I got my engine mounts a few days ago and have the car on jackstands right now getting ready to install them, the one question I have is what are the torque specs for the four pedestal bolts when putting everything back together?

Thanks in advance,

Robert

Hi robertway, 37 lb-ft is the correct torque value you are looking for.
