Good luck :)

Still, you can have flame outs after refueling. Don't never fill fuel in the neck of the tank. When the lid closes, you'll have too much pressure in the tubes and the engine will run too rich. Mount an fuel filter (without the filter insert) as close as possible to the tank in the pressure tube from the exhaust.

M7H taught me that:

What is the best pipe for fuel. I'm switching from go and looking for long run times and smoth power transition.

Buggy or truggy ?

9901ss/41005 buggy
2084ss/41021 truggy

Works on most novarossi engines , 9886/41021 is another AWESOME buggy pipe combo that can even be used on truggy

Main buggy but looking at running this in both. Do I need the special header to run in Mugen

NitroLuver 07-27-2010 08:26 PM

might be getting a bf3 port and I was wondering will a 9901 pipe kill this motor or make it a pretty good runner? I know a lot of people run the 9886 but I would like to know if the 9901 will do the trick?

JANKEII 07-28-2010 09:17 PM

I wish the 9886 was a ss pipe. Would buy more. To fragile for the price...

Yes, 41030 (long) 41029 (short)

sdtech58 07-29-2010 07:09 AM

Anyone running those "Stacker" venturi's from Innovative Designs? Just curious as to the performance vs. a standard venturi. They are about 2x the price, so wondering if they are a waste of money compared to the $7 Nova inserts? BTW, I run a modded N21BF with Dynamite 086 pipe on primarily small tracks.

Thanks

In the market for a new motor and have been looking at a S21P5XLT,,,,read that this motor can use standard and or turbo plugs, with a button change? And that this motors specs are nomore that 25% nitro content and no less than 10% oil? the reason is im a budget racer and currently (have allways) run 20% nitro fuel(Sidewinder 20%-12%oil) and standard plugs, helps me keep cost down,,, is this a good motor for me to buy , does it fit into my fuel and plug choice? thanks guys for all the help, this board and thread is awesome!

U can use any % nitro fuel as long as the engine is properly shimmed for it .

Not sure that the new button design is offered in standard at the moment , I haven't found it yet if it has anyway and I look for that kinda stuff so I know ;)

look me up [email protected] ,I will see what kind of options I can come up with for ya :D

i have 3 n21bf's and love them!...i was just wondering what you guys would recommend on a plug choice!...i live in southern california where its always 80 degrees or hotter!....i am also currently running a jp4 pipe and header!...what pipe/header combo do you recommend running on these motors!

merdith6 08-03-2010 03:01 PM

Great Question

When the temps are colder outside or even a bit cool I like to run the mccoy mc-8 plug, it's a medium plug, but a bit warmer than a odonnell 99 plug. the 99 plug works great in the hotter months because the engine is running hotter by about 25-30 degrees and a thinner wire in the hotter plugs gets burned up too fast, try the odonnell 99 plug in the BF. and good luck at the races.....

Oh yeah, the most popular pipe is the top end 9886 with the medium or short header, and the 9853ss is my favorite with the short round header.....I have heard the jp4 works great on Novarossi engines, but I haven't tried them and I do recommend the Nova Pipes and Headers.....

deadmancourt 08-03-2010 10:08 PM

:cry:bad news! i took the backplate off my nova 21bf tonight after practice and noticed the piston skirt had a chunk missing from it!...i found the chunk and quickly put the motor back together and ran it just to make sure it wasnt me that broke it when taking it apart!...i always make sure the piston is @ tdc when taking off the backplate!....the motor runs fine and hits high rpms!...it didnt want to idle,but it was 9:30@ night so i couldnt warm it up!...obviously this is no good but will this piston explode eventually?....:flaming:

Have a quick question regarding a Nova P5X: is it feasible (recommended) to put the innards of a P5X (button head/piston/sleeve/rod/crank) into a P5XL case and back-plate? :confused:

you have to use the button that comes with the p5xlt in order to use the lowered head though :blush:

are you wanting to use the new coated crankcase ?

Hi Monty. The P5XL crankcase I plan to use is actually the bare aluminum one, not the newer black one. I got it off e-Bay because my regular P5X case had a broken back-plate screw shaft stuck in the block and that was the closest replacement I could find on short notice.

The reason that I had some hesitation is that I noticed that the back-plate on the P5X has a couple of "dents" in it on either side of the channel where the bottom of the piston sits, whereas the same part on the XL did not, and it then dawned on me that the inside of the engine block was probably channeled differently between the P5X and P5Xs... Hence my wondering if the old P5X sleeve/piston/crankshaft would work or create some sort of power-robbing turbulence.

the only difference is the buttplate , the round one gives more low end torque through less case volume , try them both for yourself and you will see what you like ;)

Hey guy's I have a question about exhaust, I am running the Toro Nero in my MBX-6 and love it. I am running with a 9901SS pipe and the 41029 short header for the Mugen buggy,my track that I run at is more technical then fast but that being said there is still an 80ft straight on the far side of the track and a few solid jumps. Being that I am still very new to the offroad racing I am wondering if there is a better choice for me with pipe and header selection? I will be picking up the long version of my pipe (41030) for the Mugen buggy but what pipe and header combo would you all recommend to get the most out of my Toro Nero?

Thanks guy's

What do you feel you are lacking with that setup?

That should be a kerazzy buggy engine setup you got there:nod:

LOL yes it is a solid runner thats for sure, but if I was to point one thing out that seems to be lacking it would be the bottom end. Now that being said it only has a gallon threw it at this point and I have not gone far off the stock carb settings since break in (of which I did the heat cycle method) at this point I am 3 hours lean on the low side and 4 hours lean on the high side from stock and with this setup on the track during the tight mid section I feel it is building up and killing my low end thunder.

Get a little more fuel in it first and try the longer header. If you still want more try the long header and 2084 pipe. You can also use heavier springs on the clutch.

Good idea's there as I have a 41030 header I can try, the header springs I didn't even think about so thanks and I will give those a shot also.

I will add that I am in n o way unhappy with the performance of my setup as I was still able to manage a second fastest lap for the day and a 2nd in the A main at the last club race, I am just looking for ways to get the most out of what I have.

Thanks for the advise guy's

rotarynut 08-12-2010 07:40 PM

quick question guys,is the JP3 or 4 header the same lenght as the 41020?
would it work with a 2084ss pipe for better bottom end? I have an extra JP header. Has anybody tried the JP/Nova combo? I'm trying to save a little, I could buy 5 or 6 glow plugs with that dough :lol:

i have a n2001bf 3port.... recently discovered that the piston skirt on the exhaust side was chiped out!:cry:...it runs fine but will not hold and idle!...it idles for a couple secs and then dies,no matter how much i turn the idle screw!....will it ever idle again,with the chipped piston?.....i really liked this engine!...does any1 on here have an extra piston they can sell or p/s set?...i dont have much $:(

There's only one way the piston breaks around the skirt area ;)

Piston/sleeve set is like 70$ I believe , don't quote me on that though

yeah i know:flaming:...why is it that the novas are the only 1s who dont completely mill off the back side of the back plate!....i have taken off backplates more than 100 times and no problem! then all of a sudden bam!....i hate myself:flaming::lol:

Toro Team
 
Wow broke in a toro team and raced it today, let me tell you something, it great, It's really similar to the FMS plenty of we'll everything.....

I know it's expensive, but it is just about perfect. I do think they should include a .10 shim in the box to replace the .20 to lower the head for 25% though, minor gripe. I found one from an old p5 and there you go. Break in took a bit longer with the billet piston, but not too bad. I geared up my Mugen Mbx6 to a 14 tooth bell from 13, and put my favorite 9853ss pipe on it, and there you go.....Blazing fast, easy to tune, I freakin love Novarossi engines.....

I second your statement, I have been running mine as it came out of the box on 25% with the 41029 header and the 9901SS pipe with strong results. Seeing as you have stated a change in head shim maybe I need to look into that as I may be lacking and not knowing it. Is the 9853 a better pipe then the 9901?

Thanks

jeremiah23 08-15-2010 06:35 AM

hi guys need some advice on my nova 21-7bt,i run the engine yesterday on the track,but seems kinda weird it doesnt accelerate fast and cannot peak on the stretch,im using a 053 pipe,aluminum clutch shoes,1.0 mugen springs,am i using the wrong pipe on this engine,i bought this engine bnew and its fully broke,and other thing is this engine has the toro nero,plus 4 carb on it.

The 9853 will have a little more power at the cost of fuel economy. It depends on what u r looking for, as to better or not?

I got the 2084ss/41021 combo on my FMS that I just started breaking in,I just barely ran 2 qts thru it and it feels really good, tune isn't even close to what it should be and neither is break in. Anyone thats been saying that its weak on low end power is full o' bull poop!!!:nod:
