I'm not disagreeing with 300 hp, but they sure do fail under 400 hp. I'm guessing you've never worked on an a855....
I have dropped the oil pan on my srt-4 and installed various other bolt-ons, however I have never done a full blown engine build up. Regardless of all this I know what the balance assembly looks like.
The 6 bolts are pretty rickety, a damn stout motor but rickety. I've had both, have you? A good tune can smooth out a motor quite a bit. The a855 is better balanced from the factory as well.
Yes, I had a 2nd gen gsx with a 6bolt short block w/o balance shafts. I suppose you thought you're the only person to have worked on both a 4g63 and a855.
I went through 1 Turbo Trix (BME) trans then a Shep trans before I sold her. I'm not the noob you think I am. WTF does rickity refer to anyway? Extra vibration on a 15+ y/o 100,000 mile engine?
so what the **** does this have to do with racing??? I'm sure they come with the assemblies, what I said was prove to me that the race cars you mentioned have BS assemblies, b/c I'm pretty sure they don't....
have you ever seen the BS assembly? should I take some picture for you people?.
Well that answers my question.
In any motor sport the requires a SEALED engine they will need to remain sealed otherwise you will be disqualified and penalized. Why do you think the call them SEALED motors? If the engine comes with a BS assembly from the factory then it remains in the engine. Should I explain this more to you?? Like I said before, call Dodge Motorsports and ask them yourself. Believe what you will but that's about as much proof I will give out to internet keyboard commandos.
I agree that DCR and the SRT vendors are full of shit, but there is no magic failure number. I'm fed up hearing people say, "they break at x hp or blah blah". Stock internals will handle over 600 whp: proven. The BS assemblies are hit or miss, they may or may not break at any given level. If you want to take the risk, fine. People seem to forget that Dodge isn't the best company at designing liveable parts, as evidenced by their exploding flywheels and other engineering disasters.
If Dodge didn't encounter the BSA assembly fail during their staged upgrade R&D or running they're factory backed stage 3 race cars then it can't be that large of a problem at those power levels. Take that for what you will, I'm not here to change your opinion.
