Yep same here. 9901/41001. The 2096 pipe sucks in buggy. I've only ever used it on a modified .25 Roma in truggy to smooth it out. 7mm insert too. 9886 pipe is no longer legal in many places as it's a 2 chamber pipe.

How do people feel about a 9901/20 combo on a 4
Port?

i run 2096/41021 on my buggy geared 14/46 on mp9 ..... NEVER an issue with power

this is on my brand of novarossi built engines though ... ;)

It will rev like mad, small track?

Med/large

nova direct has both the p5xlt16 and paloma limited for $50 off, which would be better overall for a truggy and what manifold/pipe combo for each?

Paloma on a 9901/41001 by a mile.

Which pipe header combo will give the most power for a Elite 5 in a truggy.

Either a 9886 or 9853 with the 41001 manifold and an 8mm Venturi

Hello... Still worth buying an old P5XLT?
But new completion in the box?
The engine includes:

Novarossi P5XLT Engine
3 venturies: 6.0 * 6.5 and 7.0mm
Exhaust: Novarossi NR-51018 Efra 2084 and NR-NR-41021 short inline parabolic collector.

Price € 225 or easier for you. 225 dollars, everything

That's not a great deal IMO. €150 maybe.. I would expect people in the US to agree, when they can get the Elite 5 for $130. I don't think that pipe is widely used?..

Made the mistake of running the dynamite 086 on the TNS paloma ltd in buggy, good god that was un driveable too much bottom too much mid. From the crack of the throttle it was ballistic, any dip or bump when accellerating out of a corner resulted in wheelies.
Back to the truggy for it.

Is the hipex pipe better than novarossi pipe? Is cheaper and i wonder the wall is thick enough to withstand off road use. Any idea?

Does the rex legend 7 have a lot motor bottom end vs the legend 4? Thinking of running the 7 in my tekno buggy with 9901 and 41001 with a steel fly wheel.

It does compare with keep off 7, something like mito 7 torque

Current pipe and engine options
 

While I've done some seaching and reading. I have seen lots of opions on differnt pipe and header combos. I'd like to find out more about why you suggest a certain combo.

My current set ups and options:
Nova p 9853 h 41001 truggy
Nova p 2096 h 41021 buggy

Rex revenge buggy
Bonito 7xlb truggy

Options:
Mito 4offa extra
Jammin jp3 stock header
Dynamite 086hs stock header
Sh p 2060 stock header

I just got the 2096 in a engine deal and replaced the dynamite on the buggy. I really think the dynamite pulled more power out of the engine. I don't know why though.

Thoughts and suggestions...

The 2096 has always leaned an engine another 6 to 9 hours on the HSN. Start tweaking the HSN little by little and see if that helps.

The dynamite pipe is a 2 chamber pipe and the 2096 is a 3 chamber pipe. 086 is waayyy more powerful compared to the more restrictive 2096.

Better no? Good pipe yes. I have run them on Nova's. They work. I have since though went back to Nova Pipes on my Nova engines.

Thank you, what nova pipe do you run mostly, honestly i never like 9901

Any opinion on a P5XLT-16 w/ a 41021 manifold and a 9901 pipe?

That's pretty punchy on the bottom end, (fine for smaller tracks or medium tracks with jumps out of corners) I like the 2096/41021 combo for 5 ports for medium to larger tracks

All the tracks around me are really tight and rough. I have tried it out and it is pretty punchy on the bottom end. I did have issues w/ traction due to a lot of bottom end, but like I said the track was really super dry and rough. I am using the Nova clutch as it comes factory. I will have to say though that it was awesome in the midrange. Here's a shot of my B3 on the track. It's pretty tight and rough. I use the 2096/51020 on my Legend 25 w/ great success.

Switched back to the dynamite pipe. Love the way it pulls so much our of the engine. Still was seeing 10 minute run times last summer. When the nova pipe came with my mito4. I thought id give it a shot.

what is the most powerful novarossi engine?? (21)

I have their .28 7 Port in my monster truck. You can order it with either bump start, pull start, or rotor start. And it's a turbo head buttoN.

Engine, pipe, and header combos
 

I am getting more into why we run what we run rather than just running what I had or could afford.

My question is how are you choosing your combinations that you run?

Example:
I currently have a
Bonito 7xlb 7port.
Supposed to be smooth on the bottom with a strong top end.
It is recommended to run a
9901 pipe. Supposedly strong bottom end.
It is also recommendes to run the 4121 short manifold. Which provides more top end.

Viewing this they suggest a pipe to increase low end power the engine does not produce, and a short header to add to the top end the pipe does not focus on.

Correct, incorrect?

The 9901 is the best of the three chambered nova pipe especially on the extra long stroke novas. The 41021 manifold is actually really long and chops the top off significantly.

Go with 2096, 9901 will kill the top end, i have keep off 7 which share thr same parts but different bearing, unless it is a small medium technical track doesnt need top end

9901 has crazy top end when its used with the right manifold ! your issue is you simply used the 41021 and called it a day...swap to a 41001 and that 9901 will put a big hurting on a 2096 ....the 9901 has a crazy good top end when it has the right manifold ! it just doesn't like the 41021, that manifold murders its top end

Would you run the 9901/41001 on the truggy as well with a 7 port?

That's what I'm running. Woke the motor up. Truck was good before, but that combo just made everything better. More speed, same torque, better run time and it feels a little more linier as well.

Thanks for the replies. Will have to do some more swaps and runs.

Has anyone put together a chart of pipe and manifild combos or uses?

Finding just reading novas description does not always help.

Novarossi Mito7 Is no longer available on the Novarossi website.
What happened? Low sales...

Yes it is not worth having a product in production that is not sold.

Just stay tuned..;-)

I only use the 9901 and 2086 pipe with 41001 header.

On Road 2015
 

I have heard that the on-road novarossi 2015 pipe is good to use on a roma .25 .. is this just for fuel economy or a good all-round option..

These flat head screws r garbage is there a hex screw opiton for the back plate and the cooling head

That seems strange to me as the 2015 is an onroad pipe which will give lots of RPM but reduced bottom end feel. On the ROMA in truggy I run 2096/41032 and this gives great power and runtime. The power band is quite linear with the 2096. If you want even more power then 9901/41032 but this makes the power band very aggressive in my experience.

Never had an issue with the flat head screws on Novarossi engines (never heard any complaints in all the years I've ran novarossi engines). What exactly in your opinion makes the screws garbage?

As long as you are using the right size screwdriver the screws are absolutely fine. Novarossi don't do optional hex screws but I'm sure you can find equivalent thread at the hardware store.
