This review is about my experience with Perrin's Engine Mounts for Force Induction Application

Purchase Date: Jan 2013
Received Date: April 2013
Installed Date: April 15, 2013


***The pictures kinda sum it all up. The mounts are melting!***
Let me start off by saying I live in Florida and this car has been FI(Perrin Tuned Vortech & FA20Club Turbo) . The exhaust system on the car was a Perrin 2.5 header back. We only found this problem because I was switching setups to a 3inch header back exhaust system. Huge props to @Ironsquid for seeing it. I also have every cooling product on the car you can buy to keep engine bay temps down.(vented hood, ceramic coating, radiator, oil cooler...etc)

Quality: 4/5
Design looks great. Mounts felt like quality in hand. When on the car the engine mounts kept the engine from rocking. Very little NVH.

Packaging: 5/5
Came in a nice box with bubble wrap well packaged.

Install:
Can't comment on this mechanic installed them.

Durability: 1/5
The mounts have only been on for 10 months and this is the condition of them. The mount is disentgrating you can pick pieces of urethane right off.

FTFY I have them too and I'm concerned.

I have some Cusco ones sitting in a box here I'm waiting to install along with my header/overpipe. I used them on my WRX in the past and they worked great. Like others have said they aren't solid mounts.

My Perrin mounts would not fit with the Perrin overpipe. I sent them back. After seeing these pics, I'm glad I stayed with stock.

That is not normal for sure, sending PM! Sorry for the hassle. I'm not sure how many customers of ours have turbo kits installed with our header, this is the first we've seen melt! It could be that it will need additional head shielding.

[PERRIN_Chris]

I also wanted to add that with aftermarket headers and especially turbo kits with dyno time, additional shielding is going to absolutely needed on the header if it's going to be used with either the stock engine mounts or aftermarket mounts. These cars aren't built from the factory to be FI, so wrapping, shields, will need to be used.

The PERRIN engine mounts work fine on a car that uses the factory header. I believe you have an aftermarket header that was installed, which was causing the fitment issue. We have never had that issue with a factory header installed.

I think its safe to say over 90% of Perrin Engine Mounts customers and target market for them have an aftermarket header.

To extract the kind of power from the engine that merits upgrading mounts, one of the first steps is upgrading the stock header.

I used the stock mounts for all 15,000 of my forced induction miles with no issues. I really don't think aftermarket ones are required.

But they are pretty helpful with 3" overpipes

I agree that not allowing the motor to move as much can help with large overpipe clearance issues where it can contact the sway bar or the subframe. That is about the only reason I can see doing it on a street car, and I would still prefer a better designed part that wouldn't make contact on the OEM mounts.

With UEL headers even 2.5" Overpipes can have a tendency to bang against the suspension. I got the Perrin mounts as soon as my AVO kit was installed to make sure.

As far as NVH, my car was a massage chair when idling under 1000 RPMs, but we had to raise the idle because of my clutch so it's about back to normal. Though under heavy engine braking the car vibrates.

Edit: Based on reading about the melting mounts I guess I might take a look at some point. Though PTuning was just staring at my car for weeks and I feel like they would have noticed something like that. Maybe the fact that my AVO headers have always been ceramic coated has helped prevent that issue.

Gotta disagree. Have you seen how much movement the engine has in the cradle in on/off throttle? Engine mounts are probably one of the best ways to improve driveline performance in on/off throttle and ensure that torque is going to the wheels instead of needless movement of the engine/trans assembly. You can literally feel the entire driveline moving during shifting and on/off throttle conditions.

I saw how much it could move when I installed my clutch, and I couldn't get the damn engine to stop moving so I could get the transmission to seat. I still prefer the less NVH approach of the OEM mounts on the street. I am not sure why we didn't get the rear dogbone mount that the WRX/STI have.
