Gday guys

I have done my best to read each page of this thread and im sure this question has been asked ;)

Im planning on purchasing a Novarossi Plus 21-4C 2010 TEAM Ceramic Edition for my losi 2.0 buggy, can someone suggest a pipe and header combo please?

From what i gather a 41021/9901 is heading down the right track?

Thanks for your help.

Cheers

Gents,

what glow plugs are people running in these engines?

I have access to the Odonnell plugs as well as the nova plugs

I have run Odonnell plugs for several years now with great success in novarossi engines. The new nova plugs are supposed to be very good but cost quite a bit more :weird: so I would save your money

cheers

what odonnell plugs do you use?

for the plus 4 and the bonito?

We use the Nova C5TGC or C6TGC plugs. Both work great, the C5TGC gives the best idle and snap / throttle response while the C6TGC will let you run a little leaner.

what he said other than.. IMO the #6 is the best plug period.. once you learn how to tune with it.. no need for anything else.. I am running the BTTS with 6mm restrictor, 41021 header, 2084 pipe, and C6TGC plug.. I am able to pit at 13 minutes during a race.. This is the best set up i have ever used in my racing career...

It depends, but I usually replace the rod at 5 gallons and do a pinch, the bearings are usually still good.....

What are the factory needle settings on the 21+4c carb? Just trying to see how far I'm off. Thanks

Hey Chad, how is the power with the 2084? How does the engine run and mileage compared to the 9901? I have been running the 9901/41021.

interesting to see Drake has moved back to the plus4 for the Nats.

Mafield moved to the LRP engine based on a need for more power for a double triple section.

possible power delivery necessitated the move?

I'm sorry I missed ur question....
The 9901/ 41021 combo is the most popular for buggy no doubt, buuuuut
I have been using the 9853ss/41021 or 41029 (same header just different car) you would use the 41021 header in a Losi i think...

Anyway the 9853ss just gives more power. The 9901 is smoother, but the plus4 is already smooth so the 9853ss helps the engine rip a little more all the way through the powerband....Not to say the 9901 hurts performance, it doesn't, that's just another option for you to consider....I hope this helps....

I have plenty of power. to me this combo feels more like a os speed with 2060 with a touch more bottom.. That would be a fair comparison.. the runtime isnt bad either hehe :)

This is from "houston" on the 21-4 thread. Had flame out issues and went with these settings as a baseline. Both run like a champ now:nod:

base adjustments for the plus 4 carb

lsn - hold slide barrel open (engine off ) screw all the way in until you feel it stop run it back out 4.25 turns , hsn - run in until you feel it stop then back off 3.5 turns , idle gap should be approx. .6mm (no insert) or look into carb opening, close slide barrel with idle screw while pushing on the slide barrel to close it until all the opening just disappears then reopen .75 turns

this should get you very close to a "balanced carb setting" , lean the top to adjust rpm
