Follow Up on Blown Engine...Likely Spun Hub

[Demxsr]

Sorry if this is total ignorance. But how is it even possible to spin the crank hub if you have both a crank bolt capture and a crank hub spline lock?

Super sorry to see this OP. Hopefully the fact that you have the engine pulled in your garage means you can fix this for substantially less than the stealership. I think you can get an entire engine for under 10k these days.

His engine blew, and allot of stuff broke including his hub.
I doubt that a pinned hub with a cbc is designed to also survive throwing a piston out of the block.

Hmm could it be that pushing this engine ~40% over stock power on crap low octane fuel is perhaps a tad risky
It's just the risk we take when doing this.
I don't think any tuning wizardry is going to eliminate the risk with this kind of power increase, only reduce it.

But sorry to hear, engine failure isn't fun regardless, I know the pain and it's put me off doing this kind of modding again, you just lose so much time and money dealing with it

I see, I just thought his speculation was a spun crank hub was the cause.

There is a limit and this setup apparently exceeded it... i can't figure out why people or suprised when you add 300 to 500bhp to a engine and it blows lol .... hilarious

Yeah, and the same tuner has been used on all of these blown engines, hmmm

Surprised he hasn't come out to say anything to defend his company.

If he comes on here the thread will blow up and end up being 25 pages long. Just ignoring it is better for him. Letting it die on the vine

Just need to look at another company constantly defending their products and actions on here from the endless barrage of attacks to know exactly why it's absolutely worthless to waste the energy. Not taking a side, just calling out the reality.

100000% I'm assuming the motor was not built. If that is the case, take your medicine and fix it! If you do the Turbos, Build the block!! Even without the turbos, full bolt on with meth/E 50-58,67 is already pushing it. It totally sucks when this happens to anyone!! But I don't want to hear the tune blah blah. It's your fault!!! Have the guy tune it to 85/90%. There is always a chance the tune could hurt the motor, DUH. But most people trust the same few guys to do it. If not them, WHO?

[Demxsr]

Not sure were all the aggro from some people is coming from. OP is just sharing his experience. No where do I see him blaming anyone or complaining about anything. Also, if it was bad gas isn't it a real possibility that it would have done damage to a built motor engine anyway?

I've been running a stage 2 vf engineering tune since 28,000miles... up to 90,000miles now, not one check engine light or code thrown..... CSF intercooler, titanium mpe exhaust with downpipe ,93 octane only...colder range plugs gapped at about 20...afe carbon intake...totally reliable, and i just had a straight up battle , 3 pulls against a 6 speed Camaro zl1 ( 30 , 40 , 50 mph ) rolls to about 140mph.... beat him by about a car and half each pull... not to mention the 2013 to 2015 ctsv , claiming 650 wheel that I've beaten too...( similar races )....just saying I'm fast and the setup is safe ...

Must have been completely stock ZL1! 2017 and up ZL1 with just CAI, pulley and tune would have been different outcome.

Too many blown engines recently with tunes from same tuner. Can’t all be car or fuel related!

[Bmwlmr99]

It was i guess, ( the Camaro ).and he had more flywheel hp than me even if he is stock... i would guess I'm between 560 to 600 flywheel, being optimistic lol.... I'll take efficiency ( DCT trans ) over big hp numbers any day

[TurboSid]

why is everyone scared to name the tuner?

Just look on page 1 of this thread, I already did. It’s no secret, read the other threads of all recent blown engines and see who their tuner was.

Automatic ZL1 has an excellent trans. Just read up on it. Shifts as quick or quicker than our cars.

glad he had a 6speed... i do know that much for sure... I've been fast against hellcats too... point I'm making is I'm guick enough to be competitive against fast cars without blowing my BMW up!!!!!

Your correct! We do have good cars that when modded can hold their own! Comes down to driver! Enjoy your car, sounds like it’s been very good for you. You should be proud!
