This time around, I'm gonna use C8TF.

I can't swap fuel, I still have plenty O'Donnell fuels 25%.

Any detonation pitting ? yes, the surface of the piston & underhead look like moon.

Thanks for the loose conrod tip.... I never knew that until today.

Hey everyone. Does anyone know how to tell the difference between the Nova Mugen MT-12 and the MR-12. Also, what should be the running temp for these engines?

The MT12 was NR's long ROD (not long stroke) engine, the MR12 is short rod engine, comparable to the NR RS12S1.

Both engines should run well around 110°C.

Hi guys i just got a Novarossi PLus 12 3CT Tuned.

Do novarossi sign "tuned" on the back of there crankshafts? i remember once seeing a crank signed "tuned" on the back.

What % fuel do these engines come shimmed for?

Thanks!
John

I believe MR/GRP put tuned on the cranks, not Novarossi.

A mate of mine just told me the ones that said tuned were from the 2006 worlds

16%

hi guys. i'm running the ns3 for the its 3rd race few weeks back.

previous 2 races i got a decent runtime between 5'30" - 6 min. but at the recent race it just make the 5 minute markduring the finals i have to come in around 4'30" -4'45". more than that i will run out of fuel .

here's some facts - different track,different fuel ( still 16% like the previos), same engine , same pipe, same plug, same head shim..even the setups for the clutch gap and spring tension r identical, the performance were quite the same..just some gearing changes to suit the track and a bit of fine tuning ofcoz.

.any one can shed me some lightthanks

Your motor was super fast!! Both you and Paolo was like neck and neck the whole weekend. You could tell that the times were reflected by lap traffic only. Great showing for the Novarossi Engines!! I think my 353 was just a little overgeared in 2nd but had enough torque on the bottom to make up the difference luckily. Novarossi is the only way to fly for me!!!

hi Guys, just wondering what pipe do u use to match the 353 engine? anyone tried the skyline vr12plus?

2630 with short header. If you need more torgue use medium header.

Different track and different fuel are the reasons. Different fuel can give differece results. Power, run time, life of motor, etc. and tracks are also going to vary.

I just ordered a 12Plus 3-SCT tuned and I'm not to familiar with nova based motors and wanted to know what the difference is in the long and short plugs on an engine?

If I'm not mistaken, The short type is AS IF you are using 1 more shim, thus slightly you get milder compression. The long type is normal compression.

If I'm not mistaken again, some people interpret short vs long glow plug with the retain heat capability they carry. Long body will retain heat longer thus you get hotter engine temp, and vice versa.

Sorry if I'm wrong.

I never heard that AS IF... Could be true, who knows.

Anyways, heres the website where i found some information on how to choose a glowplug for your situation.
