You are absolutely right about the air filter and the flow through the intake manifold. The main reason I don't really talk much about it (I guess I should so we'll talk about it now) is because the air filters and the style and shape of the intake manifolds are for the most part pretty straight forward. You will less likely have problems with airflow to the engine than selecting the wrong pipe and /or having the wrong tune. The airfilter as you mentioned can certainly affect an engines perfromance, not so much on these engines with the length and shape of the manifiold but more with the filter density and oil thickness in the filter. I have seen 280hp 1000cc pro stock drag engines loss over 80hp because the oil on the K&N filters was too thick and the engine couldn't breath. The same could happen in these engines so you are definately right about bringing that up and it is a very good point to make to use a good filter and filter oil in order to maximize airflow but also keep the foreign debris out. I myself use the mugen round filter that came stock on the MBX5 series cars and it may come on the 6 series but I don't know since I don't run them. The main reasons are 1) good density foam but very breathable and 2) $9 for 4 filters instead of $4 per filter through xray. I also use PJ1 filter cleaner and filter treatment on them (the same treatment used on dirtbike air filters). It works very well as there is no signs of dirt entering into the engine through the filter. The inside of the filter is perfectly clean even when the outside is completely filthy. I usually change my filter several times a race weekend to keep the engine breathing properly and running strong. Even though the dirt and debris stay out of the engine doesn't mean the filter is getting clogged and not allowing the engine to breath properly. If you are good about keeping the filter changed out on a regular basis, use a good filter and filter treatment, the engine will perform just fine in most situations. I know K&N makes a small filter that will fit the carbs we use but I wouldn't trust the filter in offroad conditions. I had a couple of them in the past and while they breath great, they also let alot of smaller particals through causing premature engine wear and sometimes catostrophic failures. Companies like Losi sell a 4 pack of pre treated filters for like $6 and alot of people seem very happy with their overall performance and engine protection against foreign debris. I haven't run them myself but from a standpoint, they look like a good buy for the money.

The losi filters are good ...i am using the answer rc filters and the are awesome sold in 10 packs unoiled ...im using similar to mark on oil ...maxima fft...when my filters are needing to be cleaned i just put another filter on ..small investment big return :nod:

motor
 

dont know if i should ask here but has anybody ever tried energy release the engine and bearing additive i used it about 7 years ago in a mugen mt 12 motor with really good results cooler running bearings lasted forever and it still had great pinch with over 8 gallons of fuel and there was no mercy i used it for bashing and racing i added it to the fuel, i use it in my 3 open mod skidoo drag sleds after break in and it shows a good 300 rpm increase on a dyno run and the bearings and chain show no more metal shavings either the company claims for nitro motors just wanted to see if any body has any input thanks

can someone help me... opinions between these nova engines please...
367, +4 and Toro Nero thanks

:confused::D

application dependant;)
need to know what you are running it in and using it for before an accurate recommendation can be made


i am sure somebody could write a book on it though :rolleyes:;)

Has anyone tried out these Novarossi Exhaust Reducers ?
http://www.amainhobbies.com/product_...xhaust-Reducer

Was thinking of running one with a Novarossi Toro Nero, with the 9901 header and the 41021 pipe.
Do they acually work (as in giving you better run times ?)
Do you install them between the motor and header or between the header and the pipe?

Any information on these is greatly appreciated.
Thanks.

I'll be running it on a buggy, most probably 808 10 thanks

i was looking at some of the carb inserts..like TKO and the innovative designs one...is there any advantage to using them or is it just eye candy. thanks

tried those 20$ aluminum ones with the air splitter in the middle and never really noticed any difference . i tried it at like every angle even :confused:

i would suggest a plus 4 for the driveability of the engine . the 367 makes a decent buggy engine when clutched , piped , shimmed and plugged right , the toro nero makes really good power but is a little dependant on the same as the 367 engine .

whats wrong with the p5 ? ;)



visit me @ H.E.S.

Hott Modded Top P5X
 

Can someone give me some feed back on this motor would like to know performance and run times better for buggy or Truggy and Pipe selection

Hey Guys,

Outdoor season is comimg, I was wondering what motor/pipe combo you would recommend for buggy and what motor/pipe combo you would recommend for truggy?

Thanks for your help.

same as the p5xl ;)

5 ports are awesome running engines , great power and respond very well to tuning . :D



tuning = pipe, plug , clutch , gearing and then the carburetor :nod:

the hotmods mods are excellent mods that dont really effect the tunability of the engine but gain in power and runtime , definitely worth it:nod:

Thanks Houston!! would this be better for a truggy or buggy and power comparable to ninja B01A never had a nova need some help.

actually its hard to compare the two as the ninja bo1a was just a different feel . i have driven a few guys' cars with those engines in them and they were very good .:cool:


5 port is more of a fast workhorse of an engine and is very tuneable as i stated earlier .:nod:

Anyone tried them before?
Or Know which order they are installed?

I have been working with them the last couple of months and they work well. They have 3 different lengths available which will extend the header length by 13.5mm, 16.5mm and 19mm. The length difference between the 41021 and 20 is about 12.5mm to give you an idea of what lenghts you may want to try. I am also working maching new ones in lengths of 6,8 and 10mm to give us middle ground lengths to tune with. If you put the 16.5 and 19mm length's with the 21 header, the header acts too long and only has low end performance and falls flat in the midrange so if you are looking for a tractor pulling setup, there you go. The longer lengths will work better with really short headers and that is why I want to make middle of road lengths for those who want more than the 21 in torque but not quite what the 20 has for torque and loss of rpm. I will be working on those very soon so stay tuned;)

Are you talking about the exhaust reducer? Or the extender?

Those are two different things. Exhaust reducers really restrict flows of exhaust pulse that actually works fairly well with engines that suffer from less low rpm torque. This is why the reducer came with the 367 engine . We were told to try it on the exhaust output of the engine and it did exactly what it was supposed to do . It might just work wonders on the toro also , the toro nero is a great engine when properly tuned and reshimmed to .70mm .

Hi Houston. What pipe,plug and shimming would you recommend for the 367? Thanks

Thanks for the reply,
I was refering to the reducer, Is it still recomended to use carb restricters like 7mm when using this exhaust reducer, or do you use the maximum size you can like 9mm.

Thanks again.

Houston what kind of power to runtime can i exspect from a P5(T). I looking for a novarossi engine with Lots of power but Great runtime as well a easy 10min. I run a rb C6 now and love the power to runtime but its a little expinsive this year for me. I raced 1/10 gas for years so im very smooth on the throttle so the more power the better but it want hurt to be a little smooth. How the power to runtime on the Fms i hear its a power house ? Thanks for the info speedy

My fault bucky, I thought you were referring to the extenders. They are listed on Novarossi's site also as reducers even though they are not and thats why I was thinking you were referring to them as alot of people have asked me about them. Sorry buddy!!

mark i got the engine warmer ..saved my novarossi life ....:nod:

Good deal!! I saved alot of people's lives this week:lol: I had a ton of stuff to ship on monday morning before I packed up my sleds and headed up into the mountains for some good riding. Glad you like it!! Spread the word!!

the best running combo we found was .85mm shimming with an odonnell 77t turbo plug ( use with part #28011 turbo underhead) , 9901 or 9853/41020 ( reducer on exhaust port) with 7.5mm venturi .

buggy? or truggy?


buggy - p5xlt , .80mm shim ( the newer p5xlt come shimmed at .80mm already) , 9886/41021 and 6.5-7mm restrictor will make great power and yield good runtimes . if you wanna focus on more runtime try a 9901ss/41005 setup if you want more torque and more runtime try the 9901ss or 9853ss/41021

truggy - p5xlt , .80mm shim (.75mm if more torque needed) , 9853ss/41005 , if you need extra extra punch use 41021 and 7-8mm restrictor depending


hope this helps you speedy,
monty


btw , the p5 is a great engine and mannnnyyyy engines are based off of the specs on this engine ;)

i must say mark , those are awesome !!!

the only thng that would be cooler is if they were stylish ;)


common theme with rc these days :lol:

its true ..best money you will ever spend ..hard to beat heating engine to over 200 degrees ever time you start it without holding anything ...just an awesome tool especially for those pesky break ins :nod::tire:

What did you have on your mind Monty??? Flames? Pink Poke a Dots? Camo? I know I know, how about sheet aluminum with the word H O T stamped on it. I have plenty of those in stock:lol::p


Don't be shy Monty, if you ever need one, you can give me a shout, I won't tell anyone you bought something from me ;)

ya ya but i can buy like 7-8 heat guns for the price of 1 "the heat" preheaters ;)


they are cool though :D

i think they are cool but i dont need one , i am fine with a heat gun :cool:

i wouldnt hesitate to buy one if i thought i needed one mark ;)

btw , sorry no pok-a-dots:rolleyes::lol:

you know how everybody likes everything in their pits wrapped :nod:

sh!t , my buddy trevor even has his fricken chair wrapped :confused::weird::lol:

i refuse to get a bridge table chair wrap :lol: but they are pretty f'n cool :nod:

Are you getting heat guns from the dollar store?? The heaters are only $65. Not sure what heat gun you are getting for $8 but it sounds like a scary device:eek: Hope someone has fire insurance when that $8 heat gun fires up. Does it spark and make shooting noises too? I might have seen one of those in the dollar bin at Valu:lol:

Hell, I paid 22 dollars for one that did all that :D

I think I paid like $25 for mine but it's nothing fancy. it does the job but I always seem to melt something or burn myself so I just keep it at home in a safe place where I can't hurt anything with it:lol:

i get dealer cost on everything :rolleyes:


hobbico and hangar9 :D SA



















at the dollar tree:lol:

Thanks houston iv always heard good things about the P5. How is the power compared to the C6 which is also a 5 port engine. Is the Fms also a good runtime engine. Sorry for not saying which car buggy and before u say it Yes i love HP LOL:lol:. Thanks again speedy

Houston, Good info here, thanks

then you need an FMS in your buggy:nod:


:lol::lol:

that would be a handful :nod:


the c6 has a little different design ;) that thing is an rpm animal :nod:

i can only try ;)
