We finally got the supercharger back together only to tear one of the new teflon strips after turning it over. This time, we are taking it back apart to apply some critical thinking and creativity to the situation in hopes of getting a fresh set of teflon seals to break in without just breaking. Then, we have some unfinished business with the intake manifold's many questionable bolt holes that will need some attention.

Merry Christmas and Happy Holidays everyone! We are very close to the end of the supercharger rebuild shenanigans and I assure you that nobody is as relieved as me, next video is the last one focused on that topic and then we have all kinds of other things to get through before this engine lands itself in the Firebird for the first time.

Hello Mr Fuzzy Dice, trained machinist here. I'd like to give you a couple of tips regarding yor handling of tools and stuff like that. 1- Buy a tap wrench and to be noted any cheap thing will do. Currently you run the risk of cutting the threads at an angle as well as making it easier to break the tap itself. The one sided turning with the adjustable wrench introduces radial forces. Additionally turning with a proper tap wrench is way more ergonomic and comortable. 2- When doing any drilling operation: Spin up the drill before contact with the material. Otherwise you'll crush the cutting edges of said drill and greatly diminish its performance. With a handdrill I'd recommend going with a slow speed and very low pressure on the drill until it bites the material. At that point increase the speed to the desired amount and increase pressure. Also use a lubricant when drilling whether it is WD40 old motor oil or PVBlaster it don't matter. Any oil will improve longevity and cutting action of a High Speed Steel drill immensly especially in aluminium. 3- If I were you I'd refrain from driving in bolts soley with an impact. You run the risk of cross threading the bolt and damaging or destroying it and the tapped hole. Start them by hand afterwards you're free to send 'em home with ugga duggas. 4- Regarding the input shaft I'd suggest changing the cylindrical key to a square one by filing the hole square. The dowell pin is more likely to be sheared off than a square key. If that's not possible (the filing) you should try to ream the hole at least and get a matching pin this will reduce the possibillity of shearing by reducing the slack within the pin and its hole. Lastly I gotta say although my heart bleeds sometimes from the cardinal sins you commit in the world of machining and iron work in general I still greatly enjoy watching you push through the obstacles with limited tools and sheer perserverance. In this spirit keep it up and Merry Christmas to you sir and god bless you.

Ptfe creeps very noticeably, to the point where teflon rings/seals can be precompressed before a piston or valve shaft is installed, where it wouldn't fit if not precompressed. Temperature helps here as well. Creep is a function of time and force and temperature. So there really shouldn't be any 'break-in" but the fit improves. The snagging is probably the not compressed seals hitting the port edges. Ps. The less movement between the splines the better for longevity, perhaps you can add some bearing locking compound (a very weak one) or some method of shimming (paint, shim stock) else all that dampens the impacts (engines don't run smooth and the blower is also an uneven load) is the viscosity of the lubricant. Heat cycling the lobes in an oven a few times should help with the seals shrinking and moving to their unstretched shape, before trimming. I think you are doing a great job for how little mechanical engineering background you have, and the limited tools/equipment.
@FuzzyDiceProjects
@FuzzyDiceProjects Жыл бұрын
Good info, glad to have you watching our videos! I considered filling in the space between the splines with something but when researching it, it seemed like solutions were either permanent or so temporary that I may as well not bother as they could cause more trouble than good. Since the shaft needs to be removed from the front of the snout, it would get very difficult to disassemble the unit if I used spline/retaining compound in there. As for the seals, there are changes from compression and temperature changes, but they also do very much break in by abrading against the case. Is that the best thing for them? Probably not, but they did shave down from a half-round shape to a trapezoid to fit the way they needed to.

@@FuzzyDiceProjects well the surface roughness of the bores is not the kindest to the seals now, so there definitely will be some wear untill some clearance exists

Please take the intake off and clean out those tiny aluminum shaving. They could do some damage to your piston rings and make for a bad day in the future. Also, I'm sure someone has already mentioned: you can use some grease when tapping threads to catch metal shavings. Good luck on the build! I hope your engine runs better than my problematic Ls7.

The thread repair really should have been taken to a good machine shop. Also, lathe cutting the rotor seals is a fairly simple affair. This from a guy with a lathe and a mill in the garage... DIY is great and brings pride but you also need to know your limits and when you need to pay someone else to do it right the first time. The thread repairs will likely give you troubles in the future. A blower drive system transfers a good bit of power and needs to be rigid. The locations, thread class, and perpendicularity of your repairs leave some to be desired - this comes from free-hand drilling and tapping for the thread inserts. Done on a mill and fixed straight and solid, the manifold would have much stronger thread repairs. Good luck with it and have fun!

I got an old B&M 144ci supercharger that I am NOT looking forward to rebuilding when it needs it. I ALSO determined that I want to run a throttle body fuel injection system instead of a carb. (Not recommended by the manufacturer.) The idea is to be able to run 93 octane OR E85 (if I can find it) and only have to do minor tuning for each. Any suggestions as to what to look at in making a selection? Seems everyone is making their own nowadays.
