Depends on the tuning n fuel used, if good tune n good fuel as mentioned previously, u shouldn't have problem to get 5 gallons but very rare

Hey guys, whats the story with the Top elite 5. Good engine?? also if chossing between a 086 pipe or 9901 what would be the go?

086 without a doubt, more power basically everywhere. The 9901 is ok, but the top end is very restricted. If your track has no real straightaway it will be fine, but the 086 will feel and perform like an entirely different engine…

Agreed, best i have ever use

Takes forever to start......now!
 
So I've had my mito 4 for only 2 gallons now. When I first got it, it would start at the tiniest bump on the box. Now it take about 1 minute of on the box to start it. But after it starts she runs fine.

I've noticed that some times she would throw fuel out of the exhaust so maybe she's being flooded? No leaks, new plug, clean filters. My lsn sits close to flush, my hsn is a touch in from flush.

Using byrons 30/8.

9901 works quite good on a 41001...revs out way harder then when its on a 41021

motoclay 11-27-2016 04:12 PM

You guys talking about pinch crack me up....you realize that if it's still metal to metal it's not 100% broken in right? A well done motor will last forever as long as you keep the dirt out of it and don't run it lean. Compression is a good thing....if you are only getting 3 gallons out of a motor you are failing somewhere in your process or judgement of what is a word out motor.

To an extent, I agree with you. People get too wrapped up in "low compression".
BUT, it's still an ABC engine, therefore zero interference when cold means there's going to be a gap at operating temperature between the piston and sleeve due to expansion.
With that said, I have plenty of old engines that have no "pinch" at all. With a lot of fuel ran through them.
They run good and I could probably use them if I needed to.
However, the first sign (in my experience) of lower compression is lack of a solid low idle. Which is when I rebuild or replace my engines.
So are they worn out?
They run.. just don't idle well.

HaulinBass 11-28-2016 08:15 AM

I find when motors are starting to get wore out they go pretty soft on the bottom end.

take some head shims out..Novarossi are very conservative from factory and as the engine wear it starts to affect it...taking out 0.1 -0.2 mm worth of shims will completely change that engine and bring it back to life !! stock they have 2 x silver 0.3 mm and 1 x Brass 0.2 for a total of 0.8.... I would try removing the 0.2 mm brass first... richen the needles slightly, lower the idle gap, check the linkage and then see how it runs... If it runs good your all set, if it acts a little odd then add back 0.1 mm shim ... usually they will tolerate a 0.2 mm reduction and it can make a massive difference...

Yes...idle stability is a good tell tale sign.....and I just do a leak down hold....run it up against compression and see how long it holds.....it's pretty easy to tell if it's done or not

Just have it resized, I only charge $18.00 return shipping included. Or $30.00 if you send me the whole engine.

I do the same thing actually. It's not really something that can be explained. A good engine just "bleeds down" slower.
I also put the exhaust port up to my ear when doing it, because there's even a certain sound, I'm sure you know!
Again, super hard to describe.

Who has tested the Adam Drake motor ? What pipe worked best on it and how was your fuel mileage with the motor compared to what you was driving before you had this motor? Is it an easy motor to break in or does it take awhile like the Novarossi p5 ? What the differences between P5 and a Adam Drake motor they both are 5 port?

The engine is quite different than the p5, the crank has a different diameter and the porting is significantly different. It is a brilliant engine. It likes basically any novarossi pipe, I've tested the 9886, 9901, and the 9853. My personal favorite setup for this engine was 9886/41021 with a 7.5 Venturi. The top end is wayyy better compared to the p5. Mileage is basically the same as a standard p5.

Ofna2005 11-29-2016 01:33 PM

Hey man thanks for responding, I just purchased one of these to try . I have a 9901 that I wanted to try on it.

rotor head33 11-29-2016 02:42 PM

I have a drake with a 9901 and 41021. Fuel mileage is horrible for mine and it didn't last near as long as my reds r7. It produced pretty decent power but the internals are just generic grab off the shelf internals. Nothing special at all. Just another nova with a different color head.

Maximo 11-29-2016 02:54 PM

The Drake likes the 41005 manifold ... 9853,9901 seem to be the strongest

rotor head33 11-30-2016 05:39 AM

^^^ truth

rjkotzur 12-12-2016 07:07 AM

the top elite 5 is very similar to the nova p5 correct?

Except for a few minor differences with the crank and piston, yeah it's very similar to the p5xlt. Both are solid engines in buggy or truggy.

GAPaman 12-13-2016 07:46 PM

Is anyone running a mito 7 in buggy? I want to try it. My home track is Thornhill, so ha nice areas to really let the engine unwind. Any recommendations on header and pipe to really get the top end to unwind? I'm coming from Triton and Picco, so my nova experience is limited.

-Greg

motoclay 12-13-2016 08:47 PM

Greg I have the Mito7 in my truggy with the 9901 pipe and 41031 conical header and I have removed .02mm shims.....motor is a beast at Thornhill!!

bigdog 12-13-2016 10:01 PM

I have recently purchased a Nova Rossi p5XLT and I really like the engine but I am looking for alittle more bottom end punch. I am running a Hotbodies 815v2 with a three shoe clutch. I am also running the 9901 pipe with the 41021 header. I bought a werks 4 shoe light clutch and plan on trying it out my next day of practice. I would like to know if there is anything else I should try other than getting a good tune for the bottom end needle. Thanks

41020 manifold or 9853/41021

take 0.1 mm to 0.2 mm head shim out....it will wake that engine right up...as well get rid of the 41021 manifold, its a little on the long side and tends to soften the power ...swap to a 41033, 41001 and the engine will improve quite a bit

Hard to believe you want more bottom on a P5. I run Keep Off 4 and have too much bottom. I see so many people leaning the bottom too much to get more run time, but lose bottom end power. Try richening up the bottom a bit. I ran P5's and have tons and tons of bottom even with 9901/41201. Or it can also be your bottom is too rich? Either way, P5 feels just as powerful as my Picco 5TX on the bottom.

Can you remove the shim on all nova engines? I'm running a plus 4 btt and thought about doing this

i would say after the engine is totaly break in ...after the first galon ,,,yes you can...i aways remove a shim after 3-4 ltrs---...but i stay at 25 fuel ,,,i wouldnt recomend someone to remove a shim while using 30 fuels...and ofcourse after removing a shim you always start with checking how it responds ..looking after the temperature and hearing for strange diferent noises ,,,..there are sometimes that after removing a shim you realise that you need a new rod or a new main bearing...in some engines you need a diferent type of plug...litle colder..sometimes its all superb ...just at the begining after the shim take out you pay attention ,,,,,,,,,then you enjoy ...a more alive engine ,,,and always better botom end...:nod:

More or less yes you can.... Novarossi are extremely conservative and leave plenty of room to to remove shims.... this is why a OS Speed seems soo powerful..OS doesn't mess about and runs their heads 0.2 mm closer to the piston then Novarossi does... which can add up to a huge power increase

HaulinBass 12-14-2016 11:19 PM

does anyone know if nova built another square stroke motor with a 14mm crank other than the 3cq/nv21b?

Roelof 12-14-2016 11:49 PM

Ielasi tuned and the older RB WS series

Like the ws7III? I thought those were 13mm cranks

Yes, you are right... 13mm... (not sure about the WS7-III)

Which recommended muffler for medium-long circuits?
Thanks

Picked up a Legend 7, 41031 manifold, and 51016 (9901) pipe. Anyone have experience with this engine? I'm putting it in a buggy.

Legend 7 is very smooth, good combo with the pipe but i never like it, prefer 2096 n 9886 only for nova pipe line up
