Technical Thread

Sick of all the benchracing, memes, and shitposting which make up 95% of this board. This thread is for discussing automotive technicalities and maintenance.

Anything mechanical or electrical goes.

So, benchracing.

How do they fit so many horses in the engine?

why would you put a wheel in the engine that looks really uncomfortable

Right then, Well I'll start I guess.
If you're looking to upgrade internals on an engine what is the first thing you should upgrade?
My thought is camshaft, timing chain, probably better springs, camshaft bearings maybe.
I haven't actually read into upgrading internals but going off the top of my head of what I'd try to upgrade besides boring and stroking.

Sleeves, pistons, connecting rods. You're upgrading things that actually take the force of the combustion.

Sometimes my car will not crank. I don't know if it's the starter itself or something else. I just sanded and cleaned the terminals on the battery and the connections really good, made them look nice and shiny for maximum contact area. I also disconnected the wire that goes to the starter and cleaned the contact points on it as well, then I tightened everything up and tested it and finally applied a light coat of dielectric grease on the terminals for corrosion protection and whatnot.

I still have the issue of no crank sometimes. The thing is when I pop the hood and try again it starts normally. Could it be the heat from the engine bay that could be messing things up? I have noticed it does that when the engine is hot, like I'll pull up to the store and when I get back in to my car in won't crank, but then I pop the hood open and it starts fine.

Usually you'll do a hot cam and the usual bolt ons before you tear the motor apart.
