Jaeger Engineering in Canada sold me a similar system in 2005, works perfect!

[@HernanSpeed]

Yes!! That’s who I got the original Speed Mount from, works great! Thanks for watching brother! 👊👊

[@rudimerm7686]

Great stuff. I had no idea about the 928's issues, especially with the motor mounts and air leaks.

[@HernanSpeed]

Definitely! If the engine is not running turbine smooth, it’s time to check the mounts and for air leaks. Thanks for watching brother! 👊👊

[@BrianMalm]

I replaced my worn out steerinig bushings with Delrin ones and they make the car steer like new again! Also - I have an early 86 so I replaced the Cat with an X pipe and the sound is way better! But not replacing the pumpkin muffler with an RMB since it is loud enough with a nice growl. Keep up the great 928 content!

[@HernanSpeed]

Yesss! The Delrin bushings are also a great upgrade over the factory rubber ones! Sounds like you’ve got your Porsche 928 dialed in! 🔥🔥 Thanks for watching brother! 👊👊

[@BrianMalm]

@@HernanSpeed I've had it for 28 years! And yes... it's a 5 speed with a short shifter, S300 Porken chips with higher pressure FPR, with 121k miles. Still pulls like a freight train to redline and stops and turns on a dime!

Estoy siempre muy atento a todos los videos del 928, pero en especial mucho a los vuestros por que detallan muy bien el contenido del propio coche que es lo que nos interesa a los propietarios, yo me he gastado mucho dinero en dejarlo en perfectas condiciones y no me arrepiento de ello,

Mucho más pronto! 💯💯

Great upload! I did most of the refresh and maintenance stuff 20 years ago on my 928S2, this vid is a good reminder to do it all again (and maybe it’s time for that rear muffler bypass too)!

El video explicartvo es buenisimo, de hecho tengo en S4 del 89 manual, le hecho todo el motor, soportes, embrague, suspensiones, frenos discos de freno y un largo etc de detalles, siempre mi preocupacion a sido lo pesada que resulta la direccion en parado, y me a sorprendido mucho tu explicacion , asi como los bujes de la cremallera de direccion, hablando con mi especialista del 928 que son poquisimos los que hay aqui en España, hablabamos de colocar la bomba de dirección del GTS que va mejor, pero viendo este video no se que seria mejor..... Muchas gracias por el video

[@georgeleidig9195]

Hey Herman thanks for another great video, I love the way you edit. Regarding the rubber on the engine can you give me some advice on what thickness and strength you’d recommend. Cheers from New Zealand.

[@HernanSpeed]

The best material is actually thin rubber pads used to isolate heavy machinery. A few thin 5-7 mm pads sandwiched in will work great. After engine is lifted, stack them in little by little. Important: get a strong light so you can see everything! Thanks for watching watching brother! 👊👊

[@djhightopfade4940]

Thanks for posting your real life experiences with the 928. I was looking for reviews on the Speed Mount. My collapsed engine mounts on my S4 don't bother me. Are there any consequences for not replacing my engine mounts? Perhaps the Speed Mount might buy me some time. I figured I would change them when my steering rack and oil pan needs service.

[@HernanSpeed]

If you’re motor mounts are shot, give the Speedmount a try!! The driving experience will be elevated… Go for it man, it’s worth it. No consequences from my experience, just smoothness that makes the 928 more enjoyable! Thanks for watching! 👊👊

[@michaciachowski860]

I love your videos. Thanks to them I’ve decided to bought my second 928 after a long break, the 928GT. The car had the engine mounts replaced 4 years ago by the previous owner (I have an invoice for this - 2 mounts for 660 euro), but the car vibrates a lot at the idle. Why? I have a mod of RMB and X-pipe (briliant mod!!), could it be because of that? Ot maybe they just installed volvo mounts (I red somewhere that they are shorter) or it was just done wrong?What do you think Master ;)

[@HernanSpeed]

That’s a fun beast right there!! 🔥🔥 If $660 includes the labor, then for sure it’s got aftermarket ones. If it’s just the mounts, that’s about the cost + labor. The X-pipe will add the most vibration, does it still have the secondary mufflers? Or is it completely open exhaust? Check the muffler hangers, they should be rubber only.. One thing that the 928 is very sensitive towards is the insulation inside, under the mats. If it’s missing, the car will feel terrible. Make sure this dampening material is installed (front, back, hatch area), it’s even thicker on the 1990+ years. Thanks for watching brother! 👊👊

[@michaciachowski860]

@ oh yes, it’s a beast and it’s sounds like a beast :) This is how this cars should sound! This cost was only for parts (in 2020) , labor was a different story, because it was a huge service. That's why I'm surprised that the car vibrates. The engine, when I move the throttle, moves quite noticeably relative to the body so the mounts are working.

[@HernanSpeed]

If they used factory parts, it’s a well serviced car. Next step is to mount it on a lift and check the exhaust for rubbing. That’s the same setup I had on my 928GT, I even had solid transmission mounts. It should be very smooth

Just be aware the RMB is a great update but the downside is increased drone sounds at highway cruising, at least this the case on the 32v cars.

[@HernanSpeed]

Yes, it’s definitely louder and aggressive. It’s still less noisy than modern V8’s like AMG’s or Corvette’s. The best option would be an electric cutoffs just before the final muffler, to switch it on/off. Thanks for watching! 👊👊

[@michaelbenno]

@@HernanSpeed yes, you can actually use a vacuum actuated exhaust valve. I have this solution on my exhaust. The valve is partially closed when there is high manifold vacuum (idle and cruise) and then the valve opens fully under high load (accelerations and WOT) simple and effective.

[@HernanSpeed]

Yess! That would be even better! 💯💯

[@pacificbuildingcare]

I'm just wondering how much these parts cost and what the labor cost is for each modification or hours I mean. I can calculate the hours with my mechanic when I buy my Porsche 928.

[@HernanSpeed]

For the motor mounts, you have two options: oem or aftermarket. Many people put in Volvo motor mounts without issues, cost is about $150. The labor is the biggest expense. For an experienced tech with air tools, about 10-12 hrs…more if it’s his first time. Make sure that your mechanic knows 928s before servicing Thanks for watching! 👊👊

[@clearcandortv5727]

I’m torn between buying a 911 997 and a 928 S4. I know your brother is more of a 911 fan. Herman which would you purchase between the two? I think I know your answer, but I wanted to double check, 🤔

[@HernanSpeed]

You must go drive them! One of them will speak to you! I can tell you one thing that’s for sure, there are more ‘mint’ 997s for sale VS 928s. Condition is a huge factor when buying a Porsche 💯 Thanks for watching brother! 👊👊

[@davidperdue1325]

How big of a job is it to actually replace the motor mounts?

[@HernanSpeed]

It depends. An experienced master tech with air tools can do it in about 10hrs. If done at home for the first time, it will be many times that. While in there, it’s a good idea to do the pan gasket and check for leaks everywhere. It’s one of the bigger jobs. Thanks for watching brother! 👊👊
