ya i guess it looks pretty nice...next time, i would point the "fangs" tilting more away from the exhoust port..meaning it should have more angle instead of pointing vertical...btw, i believe JB Comp and SavageJim are really good at doing this stuff..fyi


Thanks for the recognitions, we (or at least I) basically gleaned our knowledge from these foums. I also learned from looking at RC mags and viewung dozens of sleeves modded by pofessional modders.

Other modders on here who have very nice works are ABmods, Supertib, and several more that slip my memory. These guys will mod sleeves and engines as a service, and they too have contributed alot to furthering educating the rest of us on how to mod engines. I highly suggest seeking out their modding trheads to further learn which mods contribute best fo which sleeve pot configurtions, timing profiles, and the specific engines as a whole.



So what do you think of my first porting?
Next step is to take some more of the sleeve(not touching port sizes), knife-edge the con.rod, smothen the intake in the crank(without changing timing), put silicone in the intake to get a nice smooth flow and then bell-shape the backplate of the crank and make 2-3 channels on it like seen in soo many pics.

That is about all I can do myself I guess.

When this engine is worn out, instead of changing piston, sleeve etc, I'll get either a Picco P3 28 ABmodded to stage2 or a RB TM928(No mods).

Adam and supertib know their stuff, but not really into helping others.

I read some where that when you cut your turbo cuts in the crank you should not cut them into the trailing edge on the counter weight. I think if you cut in trailing edge of the counter weight the crank will have more vibration. (Savagejim can you back this up?)


I'm starting to get into timing (actually doing it now) I have a degree wheel and have my files on order. (Savagejim can you E-mail me I have a few questions for you)

Got the advice not to polish the areas where I've cut, not on the crank and not on the sleeve, the reason for this would be that drops of fuel would stick to a polished surface...any truth to this?

I've heard of it. I don't put a mirror finish on my stuff, just get it smooth. Look in the "car action how to port a engine" thread and you'll see some of my work.

Ok, LOL I think I've read every thread on porting on rcubiverse AND saved all the pics on my PC to study them.

I can't wait to get my files so I can start modding again, I have 4 or 5 engines right now that aren't modded then after those I have to find more engine.

I'm bidding on a really nice tungsten carbide cutter for my dremel on ebay now, hope I'll get it.

Let me see if I can post some pics today...

Please do, I'd like to see how you did it.
Thanks

Ok, even if you make them small? I've heard they don't need to be wide or deep...

They weren't very deep, but thats compressing space you're losing and if you're modding timing, you want don't want to lose that space. Because when you mod timing you will lose some space too. You can do it if you want, but IMO its not worth doing.
