Dave's subframe

[GTP#44]

Dave, don't be mad that I am posting a pic of your subframe.
Hopefully you will have it soon...If you need me to go by and help get it to you I will.
I found a picture of it, some guys have asked how it looks, maybe this will help out.

No sweat! I'm not in a huge rush for it, so it's not a big deal yet. But the communication is certainly lacking over there. Can't blame them if they are busy. We are not high priority.

Corey back at work as of tomorrow. They say he will get stuff out this week.

[DaveSkrab]

Good to know! Thanks!

Few more pics from different angles?

Looks like it has a few extra supports. Thanks for posting this!

On Jacobs race car there is an added brace from where the ac compressor bracket to subframe. http://images.tapatalk-cdn.com/15/11/11/4f1b2dc32d0a02b4f2ea06b055dbcbf9.jpghttp://images.tapatalk-cdn.com/15/11/11/83184b3320d75f61b6b83a199b5b235e.jpg
And 3" hoses feeding air into engine bay and onto the turbo. http://images.tapatalk-cdn.com/15/11/11/edb775667d1de1206c06bb9cf693d20f.jpg

That's not really a brace, it's a torque limiting rod for when you hit the gas. Makes sence since you want instant power transfer.

[polopharm]

Yeah thats right couldnt think of a better word at the time.

Same concept.
Several people at the race track and mechanics have asked if the monocoque has shown any signs of stress or cracks at the area where the subframe bolts to the carbon fiber.
Mine looks fine but evidently this is very common in monocoque race cars.
Anyone seen this problem on the consulier?

I haven't seen any cracking issues due to self induced stress in my car and it's a fairly high miler. All of the cracks I've seen on mine are either on non-structural components ( engine cover, and doors ). The stock engine mounts are pretty soft and allow for lots of movement of the engine so that most of the vibration isn't transferred to the car, even with the solid strut, passenger side hiem buckle, the engine still moves quite a bit. No wonder they installed the front torque limiter.

The engine subframe seems to be held in quite well ( front, top and back ). Now I still don't lift the weight of the car with the body for any length of time, lift just enough to pull the belly pan so I can then lift / support on the subframe. On the front I feel fine about leaving the suspension hanging from the car...but not the engine. Even then the front will be supported by stands on the subframe.


....One thing I see that's missing from Dave's subframe is the trans upper support brace...the little diagonal piece that the trans mount connects to.

Many many many GM products use torque limiting rods. I think SRT-4's also used something like that.

Several Consuliers had that issue. Primarily Series 1 cars. Which was one of the deciding factors for me choosing a series 2. When walking through the rossion warehouse a buddy of mine and I noticed it on at least 4-5 cars, that were present there. When comparing series 1 and 2 side by side, we noticed that some where along the line the molding process changed (different resin used, they may have started autoclaving at that point?)
In short, yes they will crack at the mounting points on the rear subframe.
