So you reckon 450HP would be a reasonable daily driver (haha)? Myna said his 7mm elements can supply up to around 600hp. What kind of turbo would be needed to let 450HP breathe? Also, BSR's 606 melted the pistons at around 500hp. Would getting the pistons coated help mitigate that issue if not a tad? Anyone have experience with piston coatings?

They are already coated in OE form.

(12-17-2013, 12:35 AM)97e300 Good to know! So what can one do to avoid a meltdown?
Intercooler, properly sized turbo, free flowing intake/exhaust, etc.
Maybe dropping the compression if you wanted to go to crazy boost levels?

Watch EGT's, use water injection, or nitrous
but water/meth does better at lowering egts than nitrous does.
Some say nitrous sky rockets egts and some say it lowers then, so I guess it depends on your setup.

something is wrong if the pistons are melting.
BSR claimed 500bhp but never showed a dyno graph to prove it, i asked to see it but they never replied.
although they have commented lately about the piston problem,
"It seems the engine will not run for that long without the cooling effect that sufficient oil flow towards the pistons provide. The oil flow problem again, is caused by cracks"

untill ir revs out on that gear. he had an welded 3.69 before, but an 2.47LSD now, so perhaps the extra resistance would kill the engine, he is going back to a 3.07 and 6speed as it looks now.

thanks, it's a cool vid but what I have asked for is for how long in time did he manage to drive it so far when tuned with the hx40 and 8mm with 3,2 bar
I have to admit, these can be tricky for differentials..

i think it was turned up to more like 4bar at the begining, dialed down, and peaks at around 3.4 nowdays.
lived its first life in the northern part of sweden like half a year, raced a couple of SLS AMGs and other cars, not pampered at al.
1/4 mile on 13.75seconds something 189km/h
we drove it 1200km from northern sweden to gothenburg, (highway speed)
he layed out perhaps 300km extra with rough driving, changed differential, drove 200km to trackday, raced a couple of laps, untill the gearbox broke down.
right now he is on the look for a replacement gearbox, the 717401 lost the third gear,

Hi, thanks, it let's us think that that set up seems reliable for track days and under heavy load.. (despite the gearbox failure)..
Reliability definition may however vary depending on the period or expected distances of the test.. I'd say about reliability of unopened om606 if someone have driven it for over 50tkm with pressures of >3bar..

Next engine will have compound turbos and we have already made very succesfull tests. I think we have enough power as it is (it burns tires up to 220kmh with dry tarmac and road legal tires), but we want it to behave like modern turbodiesel plus get rid of the smoke. We'll see how it turns out.

02-11-2014, 05:47 AM #25Original bottom end seems to be very tough indeed. We are using Arrow rods, but we like to think that even original rods would do current 693bhp/1250Nm just fine. This engine did around 20 000km and wore 8 sets of rear tires before it broke and we were little surprised that it lasted so long. Car is really hard driven daily driver with tow bar and full interior. IRC our best trap on 1/4 mile was ~215kmh with no traction. Apart from bottom end, nothing is original in the engine. Best power is @7000rpm and shifting point/rev limiter @7500rpm.

Next engine will have compound turbos and we have already made very succesfull tests. I think we have enough power as it is (it burns tires up to 220kmh with dry tarmac and road legal tires), but we want it to behave like modern turbodiesel plus get rid of the smoke. We'll see how it turns out.
So Janne you have found your way here, welcome, hope you have found some more time now even if children a lot of time
(02-11-2014, 05:47 AM)shadowmaker Original bottom end seems to be very tough indeed. We are using Arrow rods, but we like to think that even original rods would do current 693bhp/1250Nm just fine. This engine did around 20 000km and wore 8 sets of rear tires before it broke and we were little surprised that it lasted so long. Car is really hard driven daily driver with tow bar and full interior. IRC our best trap on 1/4 mile was ~215kmh with no traction. Apart from bottom end, nothing is original in the engine. Best power is @7000rpm and shifting point/rev limiter @7500rpm.

No fire rings, just VHT copper gasket cement.
This is one of the first 1/4 mile runs after my involvement with this car. Owner had made several 1/4 runs over three years before and his best was something like 13,7s/192kmh. This run was with 70-80% fuelling and just 3bar pressure to see that everything is OK.
First run
Here's a second run of the day. We dialed around 90-95% fueling and 4bar boost to get the car into 10s zone. At halfway we were 0,6s faster than on our previous 11,4s pass, but @250m driver made a change miss as rear tires lost their grip around 6500rpm on 3rd gear (at that time shift point was @6800rpm). Still 11,6s with only 150kmh on the finish line. Engine got totaled by over revving.
Second run
After that we have never got the time or weather to run this car at Alastaro 1/4 mile track. We have tried "airport tracks" but there's no way to get any traction sufficient for this car as we have no room for any bigger race tires as this is a true daily driver.
Airport track
And to clarify, this isn't my car. I've just been helping out to find some power, operating range and reliability out of it as a hobby. I really don't care about gassers as I find them too easy to play with...
