I am really focused heavy on materials. Injectors are being machined mostly out of c300. crank type of4340 4140 300m or 1144. Any suggestions for that would be appreciated. Rods aluminum. Pistons unfortunately steel.. the expansion of the aluminium and the compression in the cylinder is to much...
Thank you very much. This answers my question. I figure this was going to be an issue with torsion parts and in turn is why I over did it. My common sense was telling me wow this is tiny I could break this with my finger tips. I will make my crank cam pins and even my rods and pistons...
Sorry it took so long for a reply I've been kindof busy.
Compression, 24 valve, Direct injection.
6cylinders
DOHC
I'd like to do a supercharged roots type but I want to make the engine turn first then cross that bridge.
That is great advice but knowing myself I'd never stop what I'm currently working on unless some major happen.
Well I look forward to checking it out once you do.
Valves are a bridge I haven't yet crossed. I've mocked up everything. Assembling everything now and setting the tolerance to see...
I actually work on engines generators digital boards etc. Tiny bit of machine work. At this small of scale things are different. I'll figure it out tho.
Thanks for your help.
I dont plan to shelve it.
Stock diameter I set to .75in
Will work from that point.
And yes that's how I got to where I am now.
I guess what I'm looking for is this ok and it will be able withstand the forces
I should just cross that bridge once there.
Haha. The plunger is for getting the head out of a$$!
But what I'm asking is..
Am I over sized or undersized. Feel like I go to far on some things not enough on others. Looking for a little insite what someone has found for ratios between these sizes that works good or best.
-Crank journals. 7in...
So I've never built a small scale engine before. I'm working on a inline 6 with a supercharger. Have questions about crank rod cam sizes if I'm going to big to small?? Hoping someone my have some input on this subject for me. Maybe help with a plunger haha! Here's a picture of what I've been...
