How to port a Nitro Engine

yusstcl · 12-01-2008, 09:30 AM

I thought I had seen these here somewhere before (heck, I thought I GOT them from here lol) but I did multiple searches and came up with nothing so here they are for the world to see once again in their full-color glory!

I dunno how well this is going to work for posting them, if anyone wants the originals let me know.

Also, here are some pics of the porting job I did on my old savage .25... it went from "Yah this truck is fun" to "Holy crap! It's ALIVE!!!"

also see here for more info Nitro engine mod

How do you adjust engine timing on nitro engines?

It gives a better spread of the combustion and with that a wider powerband.

Just do a google search to "Singh grooves"
