Maybe I just had a bad one or it wasn't tuned correctly. How are the Nova's to tune compared to OS engines?
But I'm not 100% sure if the carburetor is the same as Mito. |
Alright, so I ordered a Mantra to run with a 9901/31 set up. For those that have the engine, is it necessary to replace the rod after break in?

I only replace a rod after a pinch

I have been running the Mantra for a little while and I love it. It has lasted longer than my Mitos. I have about 4 gallons on one, and if I can get back to getting 8-10 gallons on my Nova engines then the Mantra will be the best Nova engine I've ever used.
Great powerband and incredible mileage. Easy 10 minute pits and can get 11+ minutes even at tracks where you generally get bad mileage. Give it a try. I don't think you'll be disappointed. |
Why a 4 port over a 5??

Nov Mito GT5 temperature issues
I am currently running a Nov mito gt5. It's originally a 2016 spec. However, I recently bought the 2017 conrod,position and sleeve pre broken in from rc target. I am running the Nov 41032 manifold and tesla .21 efra 2139 pipe.glow plug #8. I live in Jamaica and it's HOT. I'm using 20% bryons nitro gas. I haven't played with any shimming.
My problem: Ever since I introduced the 2017 parts to the engine. I have been struggling with temperatures. At factory mito settings the engine is very rich and the temp is 240-250 plus the car is lazy. So I try to lean the car out in hour increment. The high speed needle hasn't passed 3hrs or 1/4. The low speed needle hasn't passed 2hrs. I'm getting lots of smoke. Yet, the temp is about 300-310. The engine sounds ok... no cracking, no high revs when I come to a total stop... Should I ignore the temps? And place my attention to the sound and smoke? Btw it's about 2 months since I introduced the 2017 parts and used about 2 gallon of gas. Please help |
What glowplug do you use?
|
temperature are something, try going to a colder plug. Instead of riching it up to much.
|
Which Byron 20% fuel are you running? Some have really high oil percentage, and that doesn't help at least.

Got my MANTRA back today from Drake, if you have given it some thought , the EBIS breakin.......trust me Do it! Send it to drake for $50. Get it back in a week ready to go! And the motor just feels different. I can't explain it , but it's not like when we break them in the old way. I'll keep you posted once I get it over 200°. Rightnow the power I got at 170-180° is making this already my favorite.
