Have you ever tried the 2096? I like the 2096 on my TNS tuned Elite 5, but on a stock p5xlt it just chokes the life out of it in a truggy... buggy might be a little different.

I can see that. It did feel a little flat on the upper mid range and the top end. I wont say the 2096 woke it up, but did feel it was a little smoother in the transition from low to mid and mid to top seemed a little longer. Plus I was getting about 45-60 more seconds of run time on the 2096 with the 41021 header. The 41020 header on makes it feel about the same as the 2058...

I don't even race - just want something powerful and screamy.. Right now I have a JVD clutch on it(I think it's basically a first-gen type Werks clutch, I think now with 2x 1.0 and 1x 1.1.. Not sure though, might be all 1.1..), which does feel soft and limp. But still, for just bashing around, the 2045 seemed to have more top end and to scream better*. The 2058 to me has always seemed to somehow compress the mid-range and just get to top end really quick. Good for racing I guess, but at least on this P5 (actually a Beat B5) it felt initially underwhelming.

I think for 21's a P5 is just not going to compare to my two RB Fire 11's, which I really, REALLY like. They've got like 28-style power, but scream better and higher..

* The RB 2045 always came with two different headers, one normal, and one the bent style. What are the performance differences? I also have a 2087 I could try. Didn't get to it though due to rain... Thanks..

Well I took the Beat out and packed it up for if/when I get the buggy on a track. Took a Fire 11 out of the SC8 and put it in the buggy, and put a modded Nosram(Picco Evo 2/3) in the SC8. But now I have a quick question about modding. The same guy modded both my Beat and my Nosram. And from what I can tell, if anything the Nosram seems tamer than stock(I had a stock one before and loved it..) Does double balancing the crank, adding silicone, etc.. make an engine tamer? (I guess "smoother" is the more frequently used term...)

^^ yes when I get my engines done I ask for smooth power and better fuel mileage but it all depends on personal preference

Took the buggy out this evening to test it with the Fire 11...., and it ate a diff within a quarter of a tank. ;) I love that engine...

Hi guys,
for some weird reason my novarossi did not come with manual, i need to get the factory needle settings.
Any ideasÉ

Most .21 off road Novas are set at 3 -3.5 turns out for the main needle and 5-6.5 turns out for the low speed needle depending on which carb is installed. Doesn't hurt to start about 1/2 turn more out on both to make sure you don't run lean during those first couple tanks. Good luck.

I like to start at flush and flush to start break in and go from there to keep temps up while heat cycle, read the break in bible at the top of the engine page. Its a life saver for your engine. My novas don't hit a track tune until about a gallon and half.

I think the carb is 24069, factory needles are set for break in, just start it, according to nova instruction, recommended to open hsn 1/2 turn.

Usually i will start it n lean lsn or increase idle gap for break in, pre-heat will help for first 10-15tanks. Just break in it till the mechanical pinch goes away n tune for performance.

What is the difference in using the Rex Legend 4 and 7 port engines?

I see the 7 has more stroke 17.6 vs the 4 has the 16.8 stroke and also Max RPM Power is 800 RPM higher on the 7 port. Anything else?

How would you choose one over the other?

The 4 get a lot better gas milage

What is the difference between manifolds:
410121 and the NVR41032 or another square novarossi manifold. I am doing a onroad gt and I want speed.

Ok a question that hopefully someone can answer. I got a used still running reasonable Rex P5X and a sealed in the box never used one both Production year 2005. These are regular plugs and I run O'Donnell 099 and things have been great, but probably down on power quite a bit to today's engines returning to R/C this year. I find on my used 10 year old motor (raced in 2005 & 2006) that later in 7 min qualifiers or definitely in the mains seem to lose some power maybe leaning out as it goes.

So for supporting these 2 engines going forward after I bought most orings spares and the set of bearings:

Would the Turbo button head # 28002 I see at AMain for the P5X help out much for running turbo plugs?

Would also adding in a newer carb design if I can find one for a good deal be good enough to compete with the latest 5 ports or whatever?

If someone has questions for the first motor then I can answer with a reply. Still has great compression and piston/sleeve are in great shape.

That's a whole lot of work to be stuck with a 10-15 year old motor still.

Why not spend the $145 on an Elite 5, and not bother with all of that?

I was told it would help with run time. I am doing that to a engine I have. I know I can do well with it. But the parts didn't cost me anything. It is plenty good enough for club races and maybe our race series. I like a challenge anyways.

Socket I am considering that type of thing, where are they for about $145? I am eyeing one on ebay but would have to do an offer for maybe getting it for $150 as it was BIN for $160 range, but has an offer option.

Maybe I can sell 2 P5X's as a package on ebay one used running and the new one and just grab one of these for now and maybe grab a big power Legend 4 or 7 port or the Elite 8 for another motor.

Chris, you raced this year yet? Did you get an RC8B3? Hopefully the GLORCS gets more entries next year. I could not make Durham this weekend and won't be able to get to SPARC or Otterville races later this month, early next month, but want to race one more time in a single day event before the winter comes.

I agree with Socket, those replacement parts add up quick. Just get an Elite 5 and call it good.

I bought one from these guys before, they accepted my first offer for $150.

A buddy did an offer for $145 and I want to say they took it, or countered with $150.

I had an Elite 5, I didn't like it compared to my Keep-off4S. I run on a gigantic track with huge jumps and it's very open. If you're at all considering the Legend 4, just go with one now. They're solid motors and are VERY smooth, with some great top end.

Have you run the Legend 7 or Keep Off 7 just to get an idea for this one?

Not yet. Was suppose to at the GLORCS race. Boring a Serpent 2.2. Will probably get a RC8B3 over the winter and be ready for spring. The new buggy looks so nice. By the time I get one the bugs should be worked out.

If my engine was done I would let you try it. My Crono was fast and smooth before. When it is done it will be even better. A certain engine guy will probably do a little TLC to it. I am looking forward to it. May even start early in the states in the spring

Would love to see the buggy in person. Even better get to drive it. :)

I just had my Keep-off4 refreshed because I'm not super happy with it. It's SUPER smooth, and gets off the corner hard, but just doesn't have the top end the OS motors have. I had some light work done to it to see if that wakes it up. If not, I'm going to try a Keep-off 7 or an OS.

My honest opinion is the 4port motor quite weak for mid range and lack top end. I mean stock but for sure has the fuel economy. All depend on your liking. Even is a plus/keep-off, i believe the porting/crankshaft is same. For latest legend line i never try/see 1 running... Just my personal view on this engine.

Maybe the pros can give their opinions.

Opinions are always worth what you paid. Experience is what matters.

The pros have spoken. McBride and R Drake are running the legend 4 in buggy, and doing very well on big tracks. I saw Mcbride's car at vegas, and it was FAST. Ronda's car is pretty quick as well.

Thats why i didn't mention the legend... Stock 4btt/keep-off

Is the Mito different from the Legend?

Yes...it seems like many of the team drivers outside of Adam Drake don't run it either.

See n try 1 to believe, remember the same porting + crankshaft wont make much different even it comes with ceramics bearing n carb.

Thats why lots of ppl will mod it for extra power, are the sponsored drivers using the same marketed engine?

I decided to grab a Top Elite 8 engine as I worked out a deal for one. Has had good reviews and comments by others throughout RCTECH forums. I still like to pick up a Rex Legend 4 or 7 next year too.

Interesting motor. Based of some super old 8 port that nova made. I worried about mileage with it.

I was looking to buy a motor to toy around with my friends. (I have an MP9) I'm not sure whether to get the mito 4 or 7 engine. they both are around the same cost $300 ($321 for prerun). I'm unsure what the benefits of 4 vs 7 port are and if I should opt the couple extra bucks for the pre run motor. Any advice would be great :)

4port for mileage, 7port for power. Depends on ur liking but i prefer 7port

More importantly where can you get a mito for 300

$309 for 4 port and $319 for 7 port on the world's auction website for steel bearings versions

They have steel bearing versions? Did not know that

Don't see them on Nova site either... Sure you not talking about legend 4 and 7?

Looks like yes:

http://www.ebay.com/itm/Novarossi-Mi...item541d298bb0

http://www.ebay.com/itm/Novarossi-Mi...item43da83fec5

you can get them on their site for 293

http://www.absolutehobbyz.com/Novaro..._p_505254.html

for the steel but I would get the ceramic. The 4 is real fast, the 7 is 30 to 40 % faster. But the fuel mileage is a lot greater for the 4.

Nice...

Anybone run a Rex Paloma? What's the difference between the orange and blue Limited one (which is more powerful?), and what are they most similar to in the NR lineup? Thanks..
