I use the Lucky 7's on a losi cage. They work great.

Tip: in xtreme dust conditions use vet wrap , 3m purple is the best

U wont be disappointed and this will protect your novarossi engine very well and not restrict airflow in any measureable amount

Personally i never re-use filters , new everytime and i oil my own as every track surface requires a different level of oiling on inner and outer

Question: Our track blue grooves and to the eye it appears there isnt any dust but what I believe is that the dust is very fine and seems dirty up the outer filter pretty quickly. When the outer filter gets dirty does the engine pull the dirt thru the filter?

My theory is that by not oiling the outer filter the dirt will not collect on the outer filter and therefore it will not continue to try and pull in the dirt that is on the outer filter.

I have always run with both filters oiled but I was thinking about going this route.

In this case would be be ok to only oil the inner filter so the oil on the outer filter doesn't hold the dirt?

I have used the vet wrap and it works good but I didnt know if I was compromising air flow with all filters oiled and running the vet wrap.

I have found that if you over oil the filters that it will cause a false rich condition.

I love my plus 4. It will idle all day like this. First Novarossi and I love it.

+ YouTube Video

both filters oiled ALL the time , how much or little depends on amount of loose filter seeping dirt/dust on the track

yes too much air flow restriction will cause false rich condition

IMO

keepin your novarossi engine breathing clean air is crucial to a long useable period for your novarossi engine

I have a question: when I observe other peoples' bugs and trugs at races, they all seem so much more feathery responsive than mine. Mine's more load-up, point, and shoot.., whereas these other cars seem so much more modulated and responsive to the smallest throttle inputs. I know clutch setup is key, as is the rest of the setup. But I'm wondering if what makes the most difference is the venturi. I recently went down from a 9mm to a 7.5 in an LRP 30 truggy engine, and it seemed to make a positive difference along the lines of what I want. I ran my RB Fire 11 (C5TGC, 2058) in my RC8.2 buggy last weekend, and it was definitely lacking in the feathery responsiveness I'm talking about. Anyway, I was just rummaging around, and found some other NR venturis - 8mm and 7mm. I've gone and put a 7mm in. So my questions are:

1.) What kind of performance difference can I expect?, and
2.) How will it affect the tune?
3.) I have a bunch of Picco venturis. They're shorter, but the width feels right. Can I use them? (I'd like to try a 7.5 first instead of the 7mm, but only have a 7.5mm Picco venturi..)

I actually don't care all that much about run-time. I just want power, but with that responsiveness and hair-trigger feel... Thanks.

Lean it out.

Haha, when in doubt, lean it out!

I think hour pipe, 2058, is one of the reason, of the light switch affect, the 2045 will settle that down, and be more linear.Although, clutching also can be another issue.

anyone using antidust kit 29053

In a hb buggy with nova 4btts which pipe and manifold is recommended?

yes...but i think it requires a special clutch/flywheel to be used.....its a nice system, but it moves the flywheel a fair ways off the engine causing fitment issues...you would need a flywheel that was machined accordingly to allow enough clearance for the seal......It looks to be a great idea, but I am unsure what kind of flywheel would work with it,,,,,

Im running the Losi RE-12 in my D8 with 4Btt. i like it alot, inexpensive, good power, good runtime. I believe it is similar to a 9901, but not sure.

I guess your tune is off man, most likely to start with your idle, I think it has a too big 'opening?' and therefore a too rich LSN. That way your engine will never be snappy.

The 2058 pipe should be right

So you guys say stay with a 9mm and work on the tune? Tune now seems alright - power good, etc. Though it does cut out unless it's completely warmed up. Once warm though the tune seems good. I mean it'll spin the car out no prob. What's lacking though is feathery responsiveness. But if what you guys are saying is that this is from a too rich LSN, and a venturi change won't make a difference, I'll put the 9mm back in and lean the bottom some..

And what about the Picco venturis(Nosram actually)?
