Default Heating after it's broken in.

I know its a good idea to preheat the eng for breakin, but how about when its already broken in? I just use it for bashing. Also, why doesnt Traxxas recommend preheating their engines during breakin in their manuals. I feel that if I had done this when I broke in my 3.3 it would have lasted longer than 1.5 gallon before breaking the conrod. For now on, I will use the method in the tuning bible!

i still preheat mine and mine is broken in. I can tell the difference in the compression. My vspec i had i never preheated and it lots in pinch in half a gallon if that. My ninja still has lots of pinch after a gallon. Sounds like you may have pushed your 3.3 to much when it was broke in. And yes preheating will alwasys be a must for me during break in.

Follow the break in bible and replace your 3.3 connecting rod with a Davis diesel rod!

Your vspec didnt have alot of compresson because you didnt know how to tune, ran crap fuel, ran into tree's, and ran the buggy into water, not because you didnt preheat it.

Replace the rod when it breaks, they use the same rod.
