Today's review concerns the Forge UNOS MBC and their PowerFlex Motor Mount. I just had both installed today at TheSpeedFactor, so I only have preliminary results, but I think they are worth mentioning, because I am once again so pleasantly surprised by the results. There are no pics yet, but Martin@TSF took many during the install process of both, so I will add those later. I only provided minor assistance in the install of the mount, but did the MBC myself - was nice doing it on a lift without removing any parts other than the intake snorkel, haha.

Motor Mount

Well, several reviews and install write-ups have already been given, so I won't go into those details, but I will touch on a few things:

- Damn shop with the press closed early even though we had rushed to get the mount to them 10mins before closing, so we had to rip that sucker out. Don't ask me all the tools that went into first tearing the bushing out, then forcing the metal ring out. Without use of the press and no pipes to use to force out the bushing with the vice, we had to get medieval on that ***.
- Once the original bushing was out, re-installation was a breeze. It's an incredible simple install. The hardest part is removing the bushing. The second hard part is removing that damn undertray if you still have it (like me).

Results:

- Uh, wow. I don't know what I really expected, but I certainly was surprised. My 6spd shifts quite well to begin with, and I have no problem ripping through the gears when racing, but I have found that since I am not willing to shift that hard when daily driving (even when driving aggressively), I often miss or grind gears. It's because I'm half-assing the shift instead of committing fully. Well, I went out right away and tried a few 1-2/2-3 shifts quickly and aggressively after WOT, full-boost pulls, and it was unbelievable. I wasn't doing my all-out drag shifts, but rather my halfass daily driving shifts, and they were like butter. I found room to do a 3-4, and that worked well, too. I didn't expect such a noticeable difference, but I have to admit that there was one. I am even more excited about this next race season, because road course shifting will be a breeze.
- Extra vibration? Um, what? Hah, maybe I was excited, but I didn't notice a damn thing. I felt nothing different as far as rigidity, but I will pay more attention to this in the future.

Forge UNOS MBC

Uneventful install, since I already had a Hallman in place. I couldn't install the UNOS in the same spot on the radiator fan bolt, so I moved it over. Instead of explaining it in words, I'll just show the pics when they are uploaded by TSF. To briefly explain, I will just say that I drilled a quick hole in the straight bracket provided, then mounted the bracket/MBC on the forward bolt of the stock airbox. This causes my UNOS to stand straight up, so the knob is extremely convenient to get to and turn.

Results:

- As expected, it came with the soft spring installed, so my first test at min boost gave me wastegate pressure of 11-12psi. I did a few tests to confirm it was the soft spring, then went ahead and cranked it all the way down. Did another run and saw a peak of 21psi, which is right, because the soft spring provides a max of +10psi. Since wastegate pressure is 11psi, then 21psi is what I expected.
- In 3rd gear, I hit 21 peak, held 20 for a while, then dropped to 19 from 6500 up. I would normally go ahead and install the stiff spring to get a solid 22psi with a taper to 20psi, but since I'm installing all the Buschur ported stuff along with the Forge Wastegate Actuator w/red spring (19-24psi), I will only need the soft spring for minor adjustment of 2-3psi above wastegate pressure. I will be fine at 21psi for the next week or so.
- Since I have the MBC set to max, I'm not utilizing the ratchet system yet, but I will definitely be using it when the WGA is installed, because I will want 22psi on 93oct, then later I will want 25psi on alky , so I will want to know the exact number of clicks to make sure it's always where I want it to be.

Nice review, the bushing I noticed no vibration at first either but now after a few days I notice it a little more but the benefits are well worth the added vibration (which is minimal).

 

Please post pics ASAP.

 

As soon as I get them tomorrow, I will upload to Photobucket, then imbed them into my original post with a bump.

 

good review, as usual, Warr!

i'm very interested in one of these motor mount bushings or a "stiffy".

 

Is your MBC installed as "sneaky" as your other one? I was wondering how you were going to install it or if you were going to try and install it in the same place. I'd really like to see how you did it.

 

So you're making the switch to alky

 

Nice to hear the good results on the motor-mount. That's exactly what I was hoping for ... got mine ordered a couple of days ago.

that mount was insane but hell we were able to beat it into submission so it worked out well. Really not too bad to install.

The controller as most of you know is a very simple install and looks great under the hood.

 

BUMPED WITH PICS!

I think this Motor Mount is a far better investment than a damper. It costs far less and solves the problem directly rather than through a "band-aid" method. both together would probably be awesome, but I don't personally plan on spending that much for a "stiffy." The difference with this mount is incredible. Another thing I forgot to mention was that the stock bushing was so mushy and easy to move with my fingers. I couldn't believe it was that soft. The Forge MM has no give, though.

 

I wanted it to be in the same place, but the Hallman is much thinner, which allowed me to use it's stock, bendable bracket to mount it to the radiator fan screw just under the snorkel, but I couldn't do that with the Forge. It's too thick to re-use the Hallman bracket, and the brackets supplied didn't provide a method for attaching to the radiator fan screw...at least my imagination couldn't think of one. Part of the problem is that the radiator fan screw is recessed behind a shroud on both sides of the screw head, so it makes it tough.

This installation point, though not stealthy, is very clean, and EXTREMELY convenient for adjusting. The hoses aren't pinched, and the knob is right there pointing up, which makes it too easy to turn. Also, it will no longer be hot as hell when I go to change it at the track, haha.

 

i fully agree. the mount is a much better investment than the "stiffy"

 

Warr - do you know if the motor mount on the IX is the same as the VIII? I.E. would IX owners benefit the same as VIIIs?

 

I don't agree with you often but i think you have hit the nail on the head. The roll stop mount while harder to change is a much better option than the engine dampner. The dampner troubles me becuase it only sits on one side of the motor. In my galantvr4 poly mounts made a world of difference and after watching dozens of evo's on the dyno i'm sure this mount will be worth the trouble to change.

 

Good pics! I'm getting the powerflex tomorrow as well. That is a clean install on the MBC. I actually looked at that spot to mount mine a couple weeks ago.
