I don't really have any dimensions of the coil, I just traced an outline in autoCAD (plus I just lent out my laptop). That's why I want to get a test piece cut to make sure the coil fits properly.
Also, I've been meaning to clarify something. Morganson- The six 6mm coil mounting holes (along...
I was just waiting for Morgansons go ahead to post this.
I asked my old boss to run one on the CNC for me. I want to test and make sure everything still lines up and that the coils fit properly. Unfortunately he is on vacation so I hope to have the test piece next week.
Cylinder walls are already very close together. Why lose another .01" in such a crucial spot.
I remember watching this a while back. Some useful tips found here (fast forward to 9min for the tip about chamfering)...
Nice. I'm planning on doing the same as a half step to going turbo. I might retain the NA intake as it is supposed to help with torque and run a COP ignition.
I imagine you had to swap to a turbo engine harness too, right? Anything else I should know?
Any chance they will be done before Christmas? I may have to get myself a little present.
Either way, I'll be picking up a set when they are available.
No problem. Please make sure to print one off and see that the coils will fit before you send it off to be made.
Haha thanks. Sadly I never got a CAD job after finishing school so I started a trade. I think its time for me to get back into it though. Working outside at -20c all week sucks.
Basically there are three different coatings.
Coating the top of the piston with a thermal barrier reduces heat transfer and prevents hot spots causing detonation.
Coating the side of the piston with a dry film lube reduces friction. Less friction= More power.
Lastly, coating coating the bottom...
Sounds great! I've been thinking about using vibrant mufflers to build an exhaust but was worried about it being to loud.
What size are the mufflers did you use? Do you find it very loud or have any drone?
If you take a few measurements I'd be happy to create a CAD file most shops could use for a CNC or water jet.
I would need you to fill in all the spots with the 3 stars.
What are your power goals for this motor? And how are you going to use it?
JE pistons run a higher compression ratio at 8.9:1 vs the CP's 8.4:1. So the JE pistons will create more low end power but you are at a higher risk of detonation (with good tune it wouldn't really be a problem). The CP...
