I would imagine the 87 tune is going to be terrible though hehe.

It's going to be the failsafe mode if any condition arises it will default to low-boost... I suspect 450hp... And that will be very slow

Not sure of ill hone it or not ... I'll get a bore gauge and see where I'm at... There r a few scratches after checking each cylinder further so I may go with my other short block ..

I'll also need to measure the L19s and see if any have stretched. I have a box of spares if any r out of spec....

Measured the l19s after one time use... 10 r out of spec 4 r good

Out of spec @ 4.674 as it's has exceeded 4.665 inches.

Important to know is that l19s can be reused as many times as u like as long as they are measured before reuse and r within spec

Time to replace but in decent condition considering the power it makes and milage.

Piston skirt the coating was showing signs of wear but that's it... Certainly usable and good for a new set of rings

I'm surprised about the oil squirter, but not unheard of. Lowly street car engines have one, where high RPM race engines like the old V10 F1 engines had upwards of 14 squirters per cylinder. They do a job, so it's surprising you didn't hit a knock threshold with that cylinder when tuning....

Wow f1 used 14 per that's crazy ... My car always used a little less timing than other motors I've tuned so not having ceramic coated pistons and missing oil squirter for sure had an impact... New motor has revised pistons so this doesn't happen. Hpf had the squirter bent a little to clear in earlier motors... So this one was not bent enough...

Race Engine Technology does some really good articles on F1 engines as they clear secrecy thresholds of the manufacturers. We're just no starting to see really detailed accounts of engines from 2006 to 2009. One point of note is that I've never actually seen a picture of a piston oil squirter shown in any of the technical articles. The parts are mentioned, but everyone seems to hide how they do it...or machine the parts off before display?

I learned of an oil squirter issue on the M5425 engine through a race team, and was offered access to the part as a favor. I think you can appreciate how costly CNC machined parts of this size are. Well they weren't cheap, and I ran into clearance issues with the M54B30 crank. I solved that, crudely, but then had a chance to influence a design being done in Sweden for an enthusiast following in my footsteps with the M54B30. The design:



Hard parts:



I have a set of these in my current build, but I don't think they are available to anyone anymore. I actually paid for a 2nd set in 2011, but never took delivery due to some personal issues with my contact, and I haven't pursued it.

I don't know that you need something like this for the S54, but it would be a cool part to have in there.

Oh...and the first version of the HPF pistons I saw posted on here did not have a releaf cut into the side skirt for the oil squirter. I think they may have cut those manually when building the first engines? (I had to do that with some previous aftermarket pistons) This might have been the cause of the oil squirter issue, where a hand-cut releaf cleared the squirter when turning the engine over by hand, but piston rocking while operating may have caused it to hit.

The squirters were bent. Over time and heat etc weakens the bend and it breaks. Usually not because of actually contact. I dropped my pan and found a broken squirted and replaced that one. Did a small bend over larger area so it wasn't all in same spot. I did first pan drop late last year. Engine was built in late 2009. So it was a good 4 years before I dropped pan to find it. But it couldn't of been broken for long as that cylinder has no extra wear. I then six months later dropped pan to change my oil pump and found another squirter from another cylinder that broke after I had pan off the first time. So it's not nessesarly being hit to break it off

U can see where my squirter made contact with wrist pin area of piston on same side as squirter then made a small sideways mark on cylinder bore... The squirter shows signs of impact as well.... I suspect at high rpm it was tossed around much like a Caesar salad or margarita.

With the M54s, broken off oil squirters have been found in the pan on completely stock engines. Some people believe it's a harmonics issue...

Yeah actual contact didn't make nozzle break but once it breaks It can hit crank and get shot back up and hit all around if it doesn't get lucky to fall straight to pan

It's like with one of those escape movies when they have to go through a large fan and air duct... getting the timing perfect other wise they get munched

All parts packed up for crank balancing... From pulleys to pressure plate and everything in between to get it all properly balanced. Getting closer

...torque plate etc for boring and honing ... should be ready for final assembly soon.. Machine shop has some back log so it might be 6 to 10 days...

While the machine work is being done on my block and crank I've been configuring Infinity tune setup and wiring / integrating my new water meth system with lots of failsafes. The goals: System wide fault tolerance and then power.

Wiring of Water Meth system ...lots and lots of wires..... This is only the failsafe wiring... It integrates a flow sensor to monitor water meth and if it falls or rises above a user definable flow rate then it triggers a failsafe output which is integrated into Infinity to trigger the low boost map. The system is also armed via Infinity by using the mode boost switch on the steering wheel cruise control buttons. No more flipping a switch

This is the flow Gauge that will also flash if there is a fault as well as trigger low boost map in Infinity. Faults r : out of range flow rate , low fluid, electrical short, pump failure , controller failure, and meth leak. It also is integrated into Infinity so that the flow is logged in conjugation with other engine parameters. Great for tuning and trouble shooting. I am excited about the confidence I will have running water meth now... It should produce more power in lower rpm and more at peak rpm and load as it's a progressive system. Flow now can be adjusted based on map and rpm... The new 200psi system will allow me to run a configurable range of 500cc a min all the way to1500cc which is much different that HPF setup which was a static 1000cc @100psi ...
