Hello,

How to modify engine port?

what should be pay attention to when modify an engine's ports?



TKS

To moddify ports on any engine you can use any tool whch will be suitable for that work-needle files, Dremel with dimond bits etc.
The most important thing you have to pay attention is-what do you want to achive by modding.
Good luck.

My How-to is to send my engine to the Engine Master! Bmodified forever RULES!

who might the engine master be???

Kondo sensei.

I'd say it's DINO san.

dino san now is on a different mission.

DNA specialist, mod baby to become world champ

I think he mods too much that it leaked out. The result stands as proven.

DNA specialist? Shot ten months ago. It is too late now.....

I would like to know that HOW TO MODIFY CHILD?

that'd take more than a lifetime.

Bmodified rocks!

hi adsl
what you can do is blueprint the motor. make sure that when the piston is at BDC [bottom dead centre] the top of the piston is level with the bottome of the exhaust port. if the top of the piston comes down further than the bottom of the exhaust port, make the bottom of the exhaust port longer until the top of the piston and the bottom of the exhaust port are flush.

just be careful that you don't brake any IFMAR, ROAR OR AARCMCC rules by doing this.

i hope this helps.

If piston is not in flash, how does it affect the engyne performance? What is happening there when it is not in flash?
Just recently been proven, that if piston goes further down then bottom line of exhaust port works better. How much further-0.5-0.6 mm. anything else will not work ( 12 Novas based engines). The same with boster and transfer, but numbers are different.

Do you mean, instead of raising the top of the exhaust port, you should extended it by taking materal (0.5 -0.6mm) off the bottom of the exhaust port?

sorry i'm kinda think
