There has been no 928 to hit the track and run faster than the Anderson Beast, but it like many others has found a rod (and some other pieces of other parts) sticking out the bottom of the block. It blew , without warning, and without amzoil in its drysump!

it seems all the tricks, theories and fixes are no match for the lurking 928 oiling issue. (unless we determine that something let go , like a rod problem or some other failed component.)

Im beginning to really believe that the only solution is to use the stock stuff , or base a stroker on the stock stuff, not to make too many changes, and shift below 6500rpm while racing. However, his previous motor, which lasted a boat load of races, blew up because of the prototype carbon fiber intake leak. this newest motor blew way before its time, for sure.

I hope he tears it down and finds that it was a spun bearing and the crank is salvageable, he buys a couple of rods, a piston or two, and a new bored block, and slaps it all together and gets back out there.

Bummer. Sorry Mark! I bet he was looking pretty good agaisnt the line up of moster 911 cups and RSRs at Cal speedway this weekend! with this mishap, he had to go grab his beat up, OB 911 GT3 cup car , and go fight a bear with a knife! (those cars are out of control now with sequential shifting, 500hp, and an assortment of real racer features )

get it back together, run amzoil, shift at 6500rpm,warm it up before you beat on it, this means 50% Throttle and 4000 rpm max for the first lap, and see how that works!

I'm sorry to hear this, I'm sure in time it will be figured out especially if the engine was shut off quickly. If it was something like a Conrod bolt failure then everything will be good again when the engine is assembled. Maybe if the crank has some wear or damage on it, it could then be turned down smaller to use better rod bearings under the banner of while you're at it.

Mark sorry to hear of the rod bustin
I hope Greg Brown will be consulted for assistance in the failure diagnosis
and rebuild

Many years ago in the 1990's, I believe, I attended a tech session at the Porsche parade in Lake Placid NY. The guy running the session was one of Porsche's racing engineers who stated that 928 engines were not racing engines. So I guess no matter how successful 928 racers may be with various aftermarket modifications and talented driving skills it is pretty easy to bump up against the engineering limitations.

Sorry to hear the news Mark and hope your back out there asap with a fresh engine.

No matter how well engines are engineered they develop issues in racing conditions; just ask all the Formula 1 teams

Well that sucks.

Waiting for the post-mortem examination results.

Damn, that blows.

Mark, I told ya to take care of my car.

Bet it gets a nice make over with GB's new oiling set up.

There are so many things that can make a race engine blow, everyone really needs to wait for a thorough analysis before throwing out assumptions.

That sucks on the engine.
When the title said fastest 928 of all time thought it was going to be Carls Bonneville motor...glad it wasn't that which is the real beast of 928 motors,what does Carl use for oil and oil system?

I am voting for component failure......I'm guessing wrist pin.......

Mark has raced a near identical engine for years....this one was much more fresh....I doubt oiling had anything to do with it......a drysump failure is possible.....

MK...don't get too hung up on your "stock works, plus amSoil".....it is totally proven it doesn't work in everyone's racers (except you)..... While you have had success....you are alone (scott doesn't run anymore)......as many have said let anyone else race your car...following your RPM guidelines and see how long it lasts, 1 day at best.... 12 race days per year which translates to a 25 minute race and at most 15 minute qual.....thats 40 minutes per day.....a whopping 8 hours per year.... On the other hand I welcome you, Anderson, Fan or anyone else to drive-race my racer.....I welcome your input on suspension tuning....

I have 2.5 hours on my new racer already....more if it didn't have steering issues.....78 HOURS on the Estate since 2010...

FYI. Yesterday, started last in the cup race!!!! finished 4th overall!!! 928 still kicked ***!!!!

Rob Edwards

How were the brakes, Joseph?

poc62

LOL Mark A said dont use them you will go faster!! HA HA! The brake works ok but it can be better (from your suggestion I know how to make it better)! THX Rob

It's all rumour until we hear from Anderson.
