grrr again flameouts... grrrr i am so confused why all guys here have problem with flameouts?you are bad tuners?i waiting to come my plus 4 and you pull my enthusiasm down for this engine with the flame outs..Which is the problem, can one guy who have flameouts how he solved thems?thanks

Hi guys,
I have been racing onroad for few years and now might want to try offroads. saw Nova 367 buggy engine for alot less then the +4 and the Toro at a LHS.
i know it's a discontinued engine but on the spec its very impresive...
can please share your experience in the 367 compare to the +4 or the Toro nero, power/runtime/matching pipe ect...
thanks in advance...
cheers

mc-8 is a great plug and definitely fits the bill

odo77 is close to the same heat range as the mc-8 , the 99 plug runs great if you are an excellent tuner but sometimes it is hard to find a good balance tune with that heat range plug . ie; runs great on track but flames during decel

just run it winner , if you dont want it , trade it for something else before you ever fire it up .


if you have the mindset that you think the flame out is a problem , you are gonna freak out at the first time it dies because you need to tune it . use the right glow plug , adjust the carb properly and they run juusssssttt fine . i have had one on track flame out in about 20 gallons with the engines again PROPER PLUG AND TUNING play a huge part in not flaming out

THANKS Huston! I dont freak out with all these i am sure that my Plus4 will be ok... which is the best glow plug?i Order two Novarossi turbo C6TGC are ok?
Thanks again

before i give you a direct answer i would ask that you read a few pages on this forum and others. i have answered this question as to what i have found to be a very well balanced , excellent running glow plug about 100 times

if you cant find the answer quickly i would be very surprised

i was read this but you promote the OD this is the reason why i ask

i am not a "promoter" per se' , i recommend products that i have found to be reliable and easy to use .


odonnell 100 or 77 standard plug , odonnell 97t or 77t for turbo

HOUSTON TAKE IT EASY ON ME
BUT WHAT IS THE DIFFERENCE BETWEEN OFNA 053,AND 9853 WITH 40005
HEADER

THANKS

similar in performance but the new SS pipes do run a little different . ofna 053 is an excellent deal for a budget , torque based pipe . dynamite 086hs is a great deal for a budget , rpm (hs=high speed) based pipe .

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


answer-rc filters

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
