question on mounts

Post by screemin eagle »

ok im a lil confused about wich mounts to use and im not spending that kinda of money for buschurs stuff.now do i use the right side mounts(passenger?) is it the brackets off the block or is it the part that bolts to the cradle? and the other option was the mm 2.0 mounts correct?
Thanks

Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.

I may have an extra set of Mighty Max mounts if you still need some. I'll have to check, but I'd sell them cheap as they're used.

$25 shipped to you as long as you're not too far away. I'm in Raleigh, NC. I'll have to make sure that I also have the metal sleeve piece that hugs the engine mount. I'll try to look for the mounts and take photos this afternoon.

I noticed the mounting holes on the turbo side of the block are a little bit crooked. I was wondering if this was normal? Thanks.

Guys, what I do not like about MM mounts is how soft they are… They were designed to work with 120hp/~130ft*lbs motor. When I had a MM, I was amazed just how easily I could move the motor +1/2” by applying around 50lbs with my hand. I hate to see just how much this engine would move under 300-400ft*lbs of torque!

So my question is two fold:

- How are these working out for those who are using them? What torque are you running? Have you seen your engine on a dyno?
- Are there are any high-performance alternatives from ES or Prothane for MM?

Since I am starting from scratch on my project, I have everything set-up to work with a small block Chevy ES mounts. But I am somewhat concerned that they will be too stiff for a 4 banger :(. Has anyone used any other aftermarket mounts?

Its very simple to weld a "torque restrictor" onto the mount. Most Starion rubber mounts have a metal shield around them. You can weld a tab accross the top of it that only lets the top of the mount come up about 1/4" or less even. Shelby told me to do it once so I figured I'd give it a shot. I'll get some videos of the car on the dyno next week (this week I hope) to show if it works or not. A 400+ ft/lb car with 15 year old stock mounts... we'll see if it works.

I remember seeing metal square tubes welded to the motor mounts on Plebani’s Starion. Wouldn’t that create noise under WOT or even partial throttle, after the two pieces of metal meet?

I didn’t like that approach and went with the SBC mounts. But now, I am afraid that they will be too stiff for our light engine :(. I guess there is one sure way to find out: install them and fire-up the engine :).

Stedebani Mounts are on my upgrade path if there wont suffice.

And if you can hear anything at WOT, you're exhaust is too restrictive 8)

That isn't the type of "noise" that I was concerned with :wink: . I was thinking more in terms of the knock sensor and resultant false knock...

Does the OEM knock sensor even operate over 3000rpm? Most aftermarket knock sensors are unusable over those RPMs as well.

I hope so, or there would have been a lot of blown 4G63s :wink:

Our knock sensors will register knock as high as you will rev it.

Once you get into standalone EMS, you get to see the actual signal from the knock sensor and it isn't pretty. Our engines make a LOT of different noises. Some are filtered out, while others are read by ECU as phantom knock and you get timing retard when there no harmful engine knock. Things like tapping lifters, banging exhaust or even drivetrain vibrations are sometime miss-identified as knock by ECU. That is why it is never a good idea to introduce new noises.
