are anyone usin prothane inserts? if so, how does it feel? a big difference in wheel hop? Did it help you gain better traction? Also should i just save up and invest for hasports or will this do?

 

I'm using stock mounts filled with 3M chasis polyurethane... Work the same and is cheaper

 

Haha, Semnos style mounts. nice thinking there semmy, sounds like a good alternative.

 

There is a write-up in the projects page on using 3M window weld Polyurethane....the same thing...

 

where did u find the 3m window stuf at

 

aqgreed i also window welded my motor mounts.

 

I had them for one day and took them out the same day. They rattled my teeth loose.

 

Yup...now my interior is vibrating like crazy and i didn't fill up my rear mount.
No wheel hop at all...with a stock ride height

 

Havent used Prothane motor mount inserts, but am using the Energy Suspension motor mount inserts--virtually the same thing.

They will DEFINATELY make your ride vibrate a bit but will eliminate the wheel hop off the line.

What I did was use the 3M window polyurethane sealer stuff along with the inserts--kind of like gluing in the inserts into the mounts and filling up spaces not filled by the inserts. You can usually get the 3M stuff from windshield repair shops--got mine for like ~$17 for the tube. It takes a couple of days for it to dry if you are JUST using the 3M... If you use the inserts also it takes less time.

Results are essentially the same whether you use the inserts or not, just a matter of waiting longer before you put it in the car--if you dont wait long enough *SPLAT* they come out the instant the motor puts pressure on the mounts.

 

Do you guys think this method of construction will work on other mounts.. say some sbc mounts? I was expecting to fab up some solid (all steel) mounts for the volvo v8 project, but this almost sounds like a good plan. Do the mounts being used have to be new? I have some worn out old sbc mounts lying around some place that I could play with.. then again a new set of sbc mounts costs like 12 bucks so I shouldn't be such a cheap ***

Anyways, these things will be put to the test for a fairly heavy motor with high torque.. just wondering if this application could cross over to the RWD world.

Oh, and if you are wondering, the RWD cars motor mounts (left, right, and transmission) won't prevent wheel hop, the application is purely to save energy in the transfer, cause normally you lose a good amount of torque from a clutch drop when your motor twists - instead of the driveshaft doing all the work on the differential.

Just some hybrid thoughts, comment anyone if you follow my drift.
