blown engine BEC
MK indy with GSXR1000
today was a bad day
doing 10,000 rpm in 6th gear on motorway (on the way to a track day) big bag , smoke and a 6 inch whole to the right of the oil filter, so the engine
is finished but my question is does anyone have any ideas what may have happened and why
as im now worried the new engine i have ordered may do the same if its something i had done.

Bugger!!!
Sounds like a conrod has let go - possibly caused by a bearing issue. What did you do with regards to sump mods / baffle plate etc??
Personally i'd go for at least a swinging pickup sump with a GSXR thou.

Yup. I'd worry about oil pressure causing knackered bearings leading to funky rod forces leading to ye big hole in the block.
Definately worth looking at modified sumps. Unless you were pulling massive lateral G's on the motorway (unlikely!!) an accusump isn't
going to help and dry-sumping isn't the cheapest option...

yes baffle fitted and shortened sump
if any thing i may have over filled the oil alittle
and the only other things i have done in the last two weeks are fit a power commander and repack the end can in a view to lower the decibels

Overfilling too much could result in frothy oil if it comes into contact with the crank. I'd suggest pulling the engine out and whipping the
sump off. I'd put money on you finding a dead bearing somewhere along the crank (and bits of bearing in the sump)
Hope you get a new engine sorted soon. Worth stripping the dead one for parts anyway. Head, covers (sell on ebay to get a few quid back if you dont
need them), gearbox (keep) etc

Just out of interest and unrelated to the problem but... what speed does 10k in 6th give you?

Little you can do about it now and you'll probably never really know if it was something you did or not. Still, learn as much as you can from
whats happened - figure out whats failed / measure the distance between the bottom of the engine case and crank (and then see where this sits in
relation to the oil level window so you can judge the oil level) etc.

how many miles have you personally put on that engine? Its possible that when it was downed in its last incarnation, it might have run on its side for
a bit thus setting a bearing off on the road to destruction.

only had the car 3 months done about 600 miles i know it had done a number of track days before i got it and was told in total the engine had done
14,000 miles in both bike and car
have ordered a GSXR K4 engine with 4,000 miles so fingers crossed

14k seems quite high for a bike engine no? (to be used as a bec power plant anyway)

Big bike should cover 50k easily, if its a honda then double it.
Bike engines are mechanical masterpieces compared to car engines, F1 engineering in your hand today.
You only lose out as to get the power you need the revs so things do wear faster.

A friend had a GSXR100H, many years ago, which he'd bought new. He put nearly 150,000 miles on it in three years and it ran perfectly. He also
had a Fireblade which had done nearly 50k and was the same.
As Mark says, they are lightyears ahead of car engine design
I'd say it had been abused (like down the road sidewards in previous incarnation) and thrashed beyond belief in current incarnation.
I reckon a constant 10,000rpm didn't help, after all that'd equate to about 180mph on a bike. Might happen for a short while .........

if you were crusing at sustained 10,000 rpm thats why it let go!
if it was quick blast up to 10k and it went then i would suspect oil starvation.

They rev to between 12 and 14k depending on age of engine, IMO 10K isn't so high to cause a problem on its own.
All the best sorting it out.

You said you put a power commander in it recently.....what map was it using?

Rods break, bolts let go from time to time, you will never really know.

Not an unknown problem, here's mine from a few weeks ago, fresh race engine build. The rod you see is Carrillo, the block it's sticking
out of an overbored, reworked K2. The crying you may still hear is the aftermath.....

10K in top, by the way, in mine, when on road tyres (205/60/13) translates to 115 mph. Just about getting to the nirvana point on the GSXR.
It's why people love Blade engines, or even better, something made by Ford or Vauxhall.

Did you have it on the rolling road, to remap?
If not it could have been running lean at 10k and holed a piston?

Did you say something......... i never made it past your avatar!!!!
oh yeah, I'd say the hole in the block would be more a symptom of a rod thats made a bid for freedom like in the pics above.If the piston went
then i'd expect to find the bits in the sump (or sitting on top of the baffle plate) as i doubt they'd have the energy to hole the engine
casing.
