Post DIY: PERRIN Motor Mount Heat Shields

OVERVIEW

This guide shows one approach to adding heat shields to the Perrin Engine/Motor Mounts for the FR-S using a heat shielding pad, thermaflect tape, and steel zip-ties. The approach is to create a blanket that wraps around the urethane while not compromising mount movement, adding NVH, or limiting access to bolts.

Other ideas and implementations of this concept and more are encouraged and will be featured on the front page- add a post and the guide will be updated.








MATERIALS & EQUIPMENT

- Perrin Engine Mounts
- Heat Shielding Material (
<i>Heatshield Products Inferno Shield 6" X 14"</i> Heatshield Products Inferno Shield 6" X 14"
)
- Thermaflect Tape (
<i>Heatshield Products Thermaflect Tape 1.5" X 3'</i> Heatshield Products Thermaflect Tape 1.5" X 3'
)
- Steel zip ties
- Hole Punch (I used a leather punch, black, left)
- Needle-Nose Pliers


--

1. Gather the necessary tools and equipment for the job





2. Cut a strip that's as wide as the urethane on the mount. I eyeballed this at around 1 3/4 inches and trimmed to fit well









3. Wrap the exposed side with thermaflect tape to seal the deal







4. Mold the blanket around the mount, starting with wedging the material between the metal slot on the back. You will have some overlap.











5. Either trim the blanket and re-seal with thermaflect or leave as is...then punch the two ends to make a hole for the steel zip-tie.







6. Clean up the area around the blanket as desired, making sure bolts are unobstructed and that there is even coverage throughout








Other's Ideas:

Here's @FrX with a way to make a "blanket" out of thermaflect tape: http://www.ft86club.com/forums/showp...8&postcount=80




FEEDBACK AND IDEAS WELCOME

Enjoy! Comments, criticism, suggestions, revisions welcome. I will update the Overview with trial results and rolling aging reviews as the mounts rack up miles on my 86.

INSTALL NOTES & SUGGESTIONS

- Follow the Perrin install guide carefully. Spend the extra time to decouple the frontpipe-midpipe connection and two transmission nuts.

- UNBOLT AND TAKE OFF ANY AND ALL FRONT STRUT TOWER BARS. Damage to the fuel lines and intake coupling are well within possible if jacking the engine up too high. Taking off the stock strut-to-firewall bars are not required.

- Watch out for how your wood block will obstruct access to bolts. A good rule of thumb is that the wood block should be a little over the length of the entire oil pan.

- It is possible and recommended to take off the motor mount bolts using a mix of extensions and small 14mm sockets. Taking off the steering rack, exhaust manifold, and front sway bar will make this a lot easier, but the hassle isn't worth it if you get creative; can slide extensions under the steering rack to get at the rear mount bolts.

- Don't be afraid to jack your engine up to get that pesky driver's side out. Turn the driver's side mount different directions and take out through the back if the exhaust manifold is still on

- When installing the Perrin mounts, the lettering and arrows go INSIDE (the FRONT LEFT means driver side. FRONT RIGHT means passenger side. I don't know why they don't use those descriptions. There is a typo on the current Perrin instructions relative to these.. see if you can find it

- The spacer's flat face is to clear the transmission's lip near the rear bolt hole. You'll figure it out; orient the spacer to the rear and slightly looking 'in' to the transmission

Enjoy some bare OFH porn and some misc pics of the install

Nice DIY. The formatting and pictures are great. How do the motor mounts feel?

Initial impressions are a very welcome, direct feel throughout the entire drivetrain at un-noticeable NVH increases for anything except very small rpms (bogging down on take-off, sub 600rpm area). Idling doesn't have much of a perceived change.

Love them so far.. have the Group N's on my wrx and used those for going on three years and these perform favorably to them

Question: Is Perrin doing any R&D to come up with different materials for future mounts? (Or is this the only solution to prevent melting) Why don't the OEM ones melt?

Great write up. I will be doing a similar thing for my engine mount.

The bushings themselves (and the bushing interlock system) is from Energy Suspension. Perrin doesn't make that

Is this a known issue? Mine have felt maybe softer lately...

This thread was where I first heard of it

you'll have to inspect them to discern if the issue is on your set.. what are your mods and what are the temps seen by your setup and environment?

Interesting! I'll take a look next time I've got the under panels off. My car is vaguely stock, only relevant stuff is Perrin mounts, Perrin trans insert, white line differential and subframe inserts, and catted header with OP.
