Got a plate to try out with water/meth injection and using the other spacer as a shear plate. Anywho though it was cool...

Also been working on some more airflow mods...I call it the Dynamic InterCooler Knapsack (TM) cause we all like DICK......but it does rearrange the vectors within the quadrants of the port, most specifically within the upper quadrant along the shear plane of the injection phase.








Upgraded the blower too

I would actually believe that they are some China kinda-equivalent to metric 10.9 strength... metric 10.9 is pretty easy to come by. However, having that China-made metric 10.9 actually be qualified and within established specifications is an entirely different matter.... but it's probably close enough for our hobby uses, especially for an intake manifold application.

Remember, metric Grade X.X is different than imperial Grade Y. From my recollection:

- Metric 8.8 is about equal to imperial Grade 5
- Metric 10.9 is just about equal to imperial Grade 8
- Metric 12.9 is somewhere at or above imperial Grade 9, with both being used infrequently but Metric 12.9 is usually more easily found
- Metric 5.8 is around imperial Grade 2 or 3, and is usually lacking any identifier/mark and is prettymuch too soft/weak for any useful application where a still-cheap Grade 5 or metric 8.8 could be used instead

Wow, I love the detail in this thread! I'm curious where you even buy that (sorry I'll butcher the name) Crekote coating? I remember reading a thread a while back where a guy took a MINT Grand National and did an LSA twin turbo system and used that coating on the custom made charge piping and said that he could touch the pipes minutes after shutting it off. That says something right there!

The pics are blurry because I used my wife’s phone and then texted them and then screenshot them.

LSX B8 piston (note uneven temperature distribution)




My coated piston (more even distribution)

The panty liner is secret squirrel at least until someone figures it out .....

I broke my shoulder earlier this year (setting off a acute gall bladder attack) and finally went to the doc to get it checked out after 2.5 months of pretty good pain...anyways found out it was broke had surgery on it.... then I knocked my self out when I passed out and slammed my head on the edge of the tub for no reason while my wife was removing the bandage from my shoulder. This time was wicked, I was out for a full minute my wife said and I was having a seizure from it. When I came to I didn’t know who I was who she was or where I was.(surgery and head injury set off another acute gall bladder attack) (I’ve lost 35lbs in like 2 weeks of solid mass and I thought I was legit dying) So here I sit with 4 holes in my gut and arm in a sling....nothing to do but tinker and be thankful to be alive...but yeah I still can’t do much and I’m in no rush so unsure of when I’ll be done. I don’t have a set date to complete it.

Here's a good read on the study of oil aeration that I found the other day

Didnt read all the way through this huge thread, but saw the comments about reducing spring friction.

Although thats true, you also reduce damping that dual springs provide for the mechanical system (valvetrain). This improves valvetrain stability and results in less valve bounce (better control).

Them touching each other is what cancels the oscillating/bouncing/frequencies not the friction between them but thanks. That’s one of the reasons I chamfered the tips and coated the retainers/seats so that the spring can operate as designed and not bind. And since compression springs rotate during cycling I developed some spring rotators to help keep the valves cooler and seal better as well vs stopping them from doing so. Im also using the same principle for a spring rotator inside the oil pump to prevent binding.

Been trying to figure out how to allow the oil pump spring to rotate freely as it cycles and came up with .010” thick ptfe homemade shims. If you’ve ever changed springs in one of these pumps then you know how much they bind and chatter.....damaging the spring, causing it to have different rates, and creating metal shavings.


I have been busy designing a better chain dampener and have a couple of different hydraulic versions I’ve been tinkering with. I was looking up some other stuff and ran across this image..sb4 Dohc ls7 with a really nice chain dampener. It caught my eye instantly. I know I know dohc etc etc but still a nicer dampener
