So, i like to think of myself as a pretty mechanically inclined guy so i want to try my hand at doin engine mods.
in the past, on my street cars ive always done porting and polishing on intake and heads, so im sure ntro engines would be a breeze.

my question to you guys is, do you know where i could find any info on learning to mod nitro engines. ive got a few engines lying aroud that im pretty much gonna throw away anyway, so they are gonna be practice engines.
im not interested in takin my engines to anyone that does mods, i want to learn it myself.

thanks for the help

wow....thats surprising!

i figured SOMEONE knew where to find info/lierature on this.

ok, i know your not a fan of savages, but on the the savage-central forums, theres tons of threads and info on modding engines.

www.savage-central.com

and click the forums tab on the left, make an account and search your little heart out. there are quite a few experienced engine modders that use that forum, but i dont think theyll be willing to give out their "secrets"

but check it out, TONS of info on almost any subject you can think of.

thanks brotha from anotha motha

hahaha, no problem. have a good time looking for what you need.

There was a thread about it floating around on here a while ago, try searching things like "engine mods" and "port and polish" etc..

yeah ive already found some pretty cool step-by-step info on modding the sleeve.
but i still havent found much on modding the crank shaft and block....still lookin though!!

sleeve mods are really easy...i just finished modding 2 axial 28 sleeves but im gonna continue the search for crank mods before i fire it back up.

does anyone know if you have to repeat the break in process after you do mods...im not doing mods on new piston and sleeve so im just trying to confirm if its necessary!

yeah i did that but it didnt turn up anything really helpful...but thanks

if its a used piston anbd sleeve then no you dont have to re-do break in.

the only reason alot of people break in their motors after modding, is because most if not all modders only take new engines in the be modded. used=no break in required. at least im 95% sure. lol ;-)

an easy mod can be done to the head button also

Yep....

Cut a cross or a "+" symbol into the button and it will increase power by directing the flame of the burning fuel charge across the head of the piston for a quicker more even burn

I call "B S"

they did a test in extreme kev.... It was alot of power but it was an increase

It wouldn't hurt to re-break it in IMO. And can you post up the links you've found so far on the topic?

How the hell can you "re-breakin a motor"???


Break-in is the act of seating the piston to the sleeve.... A wear in process.... modding the ports on the sleeve in no way at all alter the "fit" if the p/s.

If anything you could richen the needles 4 or 5 hrs and work back to the new sweet spot since youve totally changed the tune of the motor

ok Rocco you got me there but I guess I meant take it slow for few tanks like you would on break-in
