Losi RE12 pipe? Good? Milelage? Power?

9901 knock off? thats what i heard...not sure if true....

Ok out of all the Nova pipe/manifold combos which one gets the best mileage forget power smoothness all that just best gas mileage?

Edit / Hpi / Crono Efra 2032 ;)

Is the Jp 2032 the same as the edit 2032? I know that it should be but the front of the JP pipe looks different then the edit pipe. What header to run with the the 2032?

Yeah they looks similar to my Edit. They are no longer approved and are very fragile unless you get the Crono SS version.
I use Novarossi 41001 header.

how about a pipe that is still available? lol

41021/2096
41021/9901

These seem to be the best for mileage. The 2096 has a slight advantage in mileage over the 9901.

Trust me, he knows what he is talking about. If you look at the last page or two of the Murnan motors thread there is a pick of how much fuel is left in my tank after a main. That was with a modded P5 and the 41021/2096 combo.

Anyone have experience with the Beat B4?

TY for the straight answer

great engine... got 8.5 gallons of solid running with it.. last 11 gallons but had to remove shims and performance drooped off and all that good stuff.. all this on original bearings

Thoughts of the 086 pipe and header for the P5XLT? Good combo?

I had tested my friend 1 with d combo, seems it smoothed the p5 brutality with good response up to top range, never tested with other pipe

Nice, thanks for the heads up!

Out of all the Nova 4-ports which engine produced the most power?

Bonito/paloma will do but from my findings, mostly will run the ⁴. Make me think....

Come on Nova gurus help me out with this answer....thanks

From what I've seen and read its probably the Keep off 4

Hey guys.. does anybody have an used piston for a Nova Plus 21-5k?.. the original owner pulled that back plate with the piston down and you know what happens after that :eek:.. the guy had just replaced the P/S/CR but, he went to pull the back plate to seal it and "doink" broke!

Thanks..

You cant get just a piston

Rex plus5 is same as are almost every 16.26 x 16.8 nova engine


My vote is older plus 21-4c team

But most power is kinda subjective, top end power,low end power ,smooth power ,midrange power , what kind of power are YOU lookin for ?

low & midrange power like Bigtime said below..

Thank you for the info!

Im looking for good bottom and midrange power....

Plus 21-4c team or mugen beat 4

Ok.... Thanks

Anyone know if Novarossi is coming out with anything new in the nova keep off 4 port line. Its almost the time for a new motor and dont want to buy the old version if there is a new one coming out.

curious , what do you see that there could be an improvement on?

the novarossi and novarossi made engines are great , very refined

some engines may have mo0re "BLING" but that dont mean jack squat IMHO

Would filling the crank on the keep off 4 help with mileage ? Or is there some magic going on in there and that's why its not filled?

seen the new "ver-tus" 4 port run today, looks awesome with alot of power...seen the stop watch with 11 minutes on it and there was still 1/4 tank of fuel left:nod:

anybody know what color carburetor washer to use for best performance with the virtus? it has a black one on there now, but also offers red, white, blue and orange.

hehe
 

That made me laugh. Bling don't mean jack squat. Perfect Monty.

You know what they say

You can polish a turd but its still a turd

hey guys I need some help, i just bought the keep off 21-4 and also the 21-7. I have a tlr 3.0 truggy and a mbx7r buggy. Which engine should i use on each? Whats a good pipe header combo for these engines. thanks

21-4 in the buggy for sure. Best all around pipe/header combo for your Mugen is the 9901/021. (same pipe and header on the Truggy as well)

Anyone try Boca ceramic bearings in the Keep Off or Virtus Engines? I thought Nova had a patent on the rear conical bearing? The Nova's are over $100. Rather run the Boca if they have that weird cone in the race. Thanks

Not sure if Boca has made this bearing yet, but I do know that there is a TKO bearing that is a direct replacement and works great.

http://tkocompetitiondev.com/product...roducts_id=576

The replacement bearing mentioned above from TKO only fits the Keep Off 21-4 engine. It does not fit the Keep Off 21-7 or Virtus engines. From my knowledge, you can only obtain the rear bearing on these engines directly from Novarossi (NOV16006)

I have one NIB which I'm looking to sell...PM me if interested.

28-7T
 

I just got a brand new Mugen MBX6-TR and its gonna be my first nitro truck. I'm looking at getting the NovaRossi 28-7T engine for it but I don't know if that will be my best option. Has anybody had success with the 28-7T? Would the .25 or .21 options be better for the truggy. Most of the tracks I run on are all technical with lots of stop and go and minimum straightaways.

Small technical tracks are one of my favorites. It makes it a drivers track and not about horse power or money track.

I would look at engines with lots of torque and low end controllability. A .28 or the Roma .25 are great with power but can be a little too much even for trucks now a days. I would look at a good .21

I recently got a .21 P5XLT Modded and couldn't be happier. Plenty of power, smooth and controllable. Yes its modded but for RPM and fuel mileage more so than anything.

Your budget should help determine weather you are going the P5 route or the Virtus route. Its about a $250 swing between the two.

Being its your first nitro, I would not spend bookoo dollars until you get the feel and knowledge of the mills. Hell, you may not like it and just dumped a bunch of money in it.

The P5's can be had for about $190. I would look at getting a mod company to do the break-in for you as that is the most important part of any engines life ( the first 500-800 cc's of fuel anyway).

And lets not forget a good pipe to match your mill, track and driving style. Pipes can bring a motor to life or pound the nails into the coffin!

Good luck.

Honestly I think i'm gonna go with the Roma .25. I like the .28 but i'm not so sure about the fuel efficiency. If i go with the Roma .25 what is the best pipe and manifold for it. Like i said on a lot of the tracks I race on there is a lot of stop and go with a few straights and 1-2 long straights. I really appreciate the help and advice.

Is there a huge difference in the fuel economy between the .21 .25?
