Deff not rich on the bottom if anything I'd say lean

My issue is my finger I think if I push hard I mean real hard I lose my economy
But still get 8.5 mins pit stops if I back of a pit I'll get 10

I'd say that is normal. I'm in the same boat.

Hey guys tell me about the p5xlt
I won one in our club raffle
Funny thing I also won a Orion crf combo as well

I don't no much about the p5

Wow , sounds like you scored

p5xlt is a very solid reliable easy to tune engine , great torque decent top end

Actually the p5 is my main race engine in truggy I run either a 97 t or 99 t odonnell plugs depending of Humidity with a 9853 pipe or 9901 pipe 41001 or 41021 manifold it's very close to the Os speeds and the 7 port novas
Cheers

Yea monty I won the raffles good
Scored a p5xlt Orion crf with pipe and a spectrum servo
Gave a few tickets to some young fellers who won some tyres lol

But that was the only good news of the week end
We held our state titles a pretty big race

In buggy I was in a bump up position running good in third when my transponder didn't count a. Lap I went from third with 40 sec in front of fourth to
Eighth on second last lap so missed out

Then in truck I made my first amain ever and broke a drive shaft on lap 39
Lol

But I learnt a lot from the top guns at this event made new freinds

As they say that's racing

yikes , no luck on the track for sure

Anybody hear anything about these new nova carbs?

http://i1197.photobucket.com/albums/...ps23b10888.jpg

^^^ that carby on the left look really weird. would love to know the difference

The left does not bring high needle???

No, it's "Pre-tuned". A new concept! :lol:

I'd also like to know more about these carbs.

Well for starters one has a mic range needle... Which you are not suppose to touch... And the other is just weird.. Lol

On the one t o the left, it is just a two needle car that they have moved the HSN into the carburator body. I am shure the have done something internal otherwise they would never been produced. The positive thing is that noone can crash you and knock your HSN of the carb, i have seen that a few times... On the down side, you can not adjust the HSN fast when your in for your refueling because you do not see the needle very good.

I three needle carb is beneficial when you know how to properly tune an engine ;-)

The real question is why does Nova need multiple carbs... And how will they be placed on their product range.

It is not as you need diffreent carburators, you do not need different shockpistons either, but it is nice to have as a tuning option. Just as pipes/manifolds and venturies. The more knowledge you have the more you can make out of enginetuning, just as you have on chassistuning.

I think the current carb is great, personally.

The three needle carb can be very useful to some. The other one almost looks like something they would put on an RTR engine.

P5
 

Question

I have a BTT turbo button that I want to put on a P5 to replace the standard button. Anyone know if it will fit? The BTT Button appears to be deeper than the standard button. Anyone know the correct shimming to compensate?

Hey guys I need some help
I have a btta that has about 6 gallons on it
The lower my fuel level Getz in my rank the shorter my engine will idle before flaming out

It has a small amount of mechanical comp
I put new button and plug new fuel lines new clutch etc
I've tried a few different tuning things
I've got two copper and one silver shim
It will come in perfect temp nice amount of smoke
It will stay running if I blip the throatle but will die under one quarter tank in 4 to 5 seconds arfter coming for a stop
However over a quarter it will idle probley

It doesn't lean bog drives smoothly etc

May pay to check for an air leak where the fuel nipple goes through the tank. Had a similar issue that I chased my tail with until I noticed it was happening when the fuel level was below the nipple. Hope this helps
Dave

Yeah try a new tank and if that doesn't fix it, get a light pinch done on it. I had a tank with a tiny crack right at the seam. It was so small it didn't visibly leak yet as soon as fuel level fell below it, the tune changed dramatically. I only found it by pressurizing it while holding it under water. New tank fixed it up.

maybe time for a repinch....who knows maybe the engine has has some hurt inside that you don't know about

Everybody hurts...sometimes...so hold on:lol:

Sounds like a pinch is in order. As the engine gets hotter the seal loosens up between piston and sleeve. If you really have 6 gallons on it, then i would have it pinched by a professional.

Yep
 

I agree most likely a pinch, but do check the glow plug and make sure it's the right one for the engine. I find the 4 ports like a slightly warmer plug and to not have a low idle. If you make the idle perfect it won't be after a few tanks and or a low tank. Bearings- I've seen some crappy bearings in the last year or so. Mostly rear ones. fuel tank- I had some issues on my mbx-7 lids not sealing properly just a thought. Fuel- if it's good it's great if it sucks it sucks. :lol:

Yea I spat the dummy 9 months of not one problem
And now drama arfter drama
I do enjoy my ep currently
But I haven't given up though

Hi I have at least a 5 year old Top P5 engine that is need of a new crankcase, bearings and piston and sleeve. Can someone please tell me where i can get these parts? Thanks Michael J

Unless you are lucky, you're probably better off saving the carb and getting a new P5xlt

+1. :nod:

Great engines for their price range..

I've got a question. I have a P5XLT that has less than 2 gallons on it. It runs so good and so strong, I can't figure out what makes the more expensive Nova engines worth the extra money. Maybe someone that has experience with all of them can chime in.

I race nitro truggy and have quite a bit of experience with the P5 as well as the higher end 7 port engines. Novarossi has refined the P5 based engine over the past 10 years and the result is the current P5XLT. I do not believe they allocate much R&D towards this platform as compared to their high end engines. The BTT/Bonito and now the Keep-Off engines leverage newer technology which requires more R&D as well as testing to keep them on the cutting edge. This combined with some noticeable upgrades such as the weighted crank, ceramic bearing(s), lower CG head, etc. understandably increase the cost.

Is there a difference on the track? Absolutely. In my Serpent 811TE truggy the P5XLT while strong does not have the top end compared to the Bonito or Keep Off 21-7. However with that said, there's probably only two tracks I race on where that extra RPM can be leveraged to a distinct advantage. Most would agree, more powerful engines can be detrimental to many off road racers so any comparison should take track and driving style into consideration.

Are the higher end engines worth the extra coin? Well I think that would have to be in the eyes of the beholder. As you can appreciate, every racer has their own opinions. I prefer the higher end engines though I'm blessed my driving experience and budget 'justify' the extra coin. Nonetheless some good friends of mine have done very well at some big races with a box stock P5XLT with the 2096/021 combo. :tire:

Thanks for the reply. I have been using the p5xlt with a Dynamite 007HT pipe and header(just because that's what I had) and I've been to a few bigger tracks where it really gets opened up. I have yet to see a car that would run away from it. Bottom or top end. Granted I'm still pretty new and my driving probably just isn't good enough to realize the benefits of a better engine yet.

Hi ron yeah I was thinking that too after i posted this. Who ever had engine before took a dremel to the bottom of it and grinded off the cooling fins on one side of the front end. thanks again Michael

P5
 

well said about the engines.

In my opinion the p5 is the best engine ever made. I run buggy only and the 4 and 5 ports seem to be ideal. The 7 ports I've had were blazing fast but never had the power directly off bottom the p5 had and were not as easy to tune, no one seems to agree. I guess I don't exactly know what they need. I have a pretty dirty collection of 4 and 5 port novas. If I had to pick one engine to run it would be a pimped out p5. For a smaller track the stock engine is perfect, but on a good sized track the clocked p5 has bottom like I'm used to and an awesome power-band that makes me a bit more cautious but has the goods. I still wouldn't say anything bad about a BTT they have a bit more updated build quality and the clocked BTT is just about the most consistently easy to drive superfast engine I've come across. So yeah, some engines cost more and are worth it and some really are not. I tend to like the less expensive engines with all the special things done to them over radical designs that may not be as reliable.

Well said Mad Dog. I kept the context of my discussion between the stock P5XLT and the higher end BTT/Bonito/Keep Off engines. I would tend to believe modified P5 based engines by HES and CRE bridges the gap nicely. Truth be told one of the finest performing engines I've ever driven was a Houston Team P5XLT. Unfortunately its life was cut far too short due to a ceramic ball disintegrating in the main bearing but that's a story for a cold winter day.

In all, great discussion...but either way one cannot go wrong with any of the options, they're all Novarossi engines. :D

Ok you guys what a ball park needle setting for a p5xlt on 30
Would it be flush and flush

Close for starters, yes I am about 1 turn in on both with a .5mm idle gap. Temps 230, 10 min tanks with an Re12 , nova 6 plug.

So with the keep off .21 being out for a racing season what is everyone's impression on it? Tune ability, run time, durably? How is the run time compared
To a btt? Thanks -Tim

Well, I haven't run it, but it should be more or less the same.. sleeve is the same, piston, crankshaft same..
Only real difference would be the larger rear bearing and crankcase. I'm no expert on that, some people say a different crankcase can make a big difference. I just think it's more or less the same sort of engine, if there's anything to these claims of spooling up quicker due to a larger bearing, the difference won't be too large.
