I've watched a basic videos on how a petrol car engine works. It would be good to find some more in depth stuff. I plan to do a few builds in the future and I would like to know how I can get hands on instead of sending it into a shop all the time.

What 'in depth' are you looking for ?

 

Exactly how each part works and how they all work together to make the engine function. That's all I'd need to do a basic build. Maybe how forced induction works.

I probably need to learn some of the maths behind it all as well.

What are you planning to do specifically?

I would be very surprised if you need to learn any math for these 'few builds' you have planned for the future.

I have a terrible idea to twin charge a BNR34. Or an r35. So compression ratios and how they work as well as what certain measurements do for an engine (bore that sorta stuff). I will probably upgrade what ever engine it is with forged rods and pistons and some other strength upgrades.

Not trying to be rude here, I'm guessing your currently not old enough to drive yet? 

If this is the case, I'd stick with just watching stuff on youtube. If you find the right channels you can actually learn quite a bit there.

How could you tell??/??/???/? Yeah I got no idea what I'm talking about haha. I'll be on P's soon.

Yeah I figured that would be the case. Just wanna start learning to see how stupid of an idea it is. In general, I want to know so I can mod in future. It's interesting to know.

Thanks!

@RA708

All good mate. 

Once you get your first car and can get hands on, that's when you'll really start to learn. 

There are a million channels worth watching on youtube, but I'd like to make a recommendation. Check out the project binky series. Just a little bit of modding happening there, I think you'll find it interesting :)

Save the youtube time, I can explain in a couple of sentences:

 

Internal Combustion Engines run on smoke which is factory installed. If at any time the smoke escapes (generally via the exhaust), the engine will stop running.

That's not completely truthful now is it? Any flex fuelled factory cars also had the option to run on steam.

And these modern "environmentally friendly" EV vehicles also run on the same smoke! When the engine, wiring, or batteries let it escape it also stops running!

Oh ok that makes so much sense. Thanks for clearing it up!

    • It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.  
    • Final thought for now. Obviously the reason I was in there was to check everything is OK cooling wise, pull out the radiator to flush it etc, but I have to say the factory has done a hell of a lot of thinking about air management in a way they never did back in the R chassis days. The Redsport/400rs have (from engine forward) 2 large shrouded fans - radiator (incl AT cooler) - AC condenser - Intercooler Heat Exchanger and Oil cooler. There are shrouds and foam around everything to keep it pretty well sealed, which is good in that they have it sorted from factory, and bad in that I can't make any meaningful improvements there. The second red sport pump water pump is mounted in front of the rad in the airflow, so I will see if there is somewhere else I can stash that (unlikely, it is tight in there). The horns which are also in the rad airflow will be moved somewhere else, and hey who needs 2 when 1 would work For track days, I can also remove the lights which would block some airflow. Factory has already taken the smart option of ducting all air that went through the oil cooler down and out of the engine bay. This pic is taken from below looking up, so air comes through the cooler at the top of the pic then hits the shroud and is directed down and out of the engine bay through the engine bay lower cover Which of course is good for oil temps, but doesn't help the rad as it diverts 10-20% of airflow away So, no big improvements to be made here, I'll flush the rad out and put it all back together.....    
    • It looks so incredibly busy in there! 😮 
    • Next..... That escalated quicker than an Elon and Donald break up! I'll post up a specific DIY for radiator removal on these, but all I'm saying is that if you get a workshop to change your radiator for any reason and they give you a $1000 bill for it, go and hug them and thank them for not charging all the hours it took.....what a bastard of a job. I'll make some adjustments as I put it all back for faster access in the future, but it was a nightmare.
