Default Pipe Choice

I have a P5 NovaRossi Rex. I've had it for several years but it's NIB still. I want to break it in for the upcoming racing season. What type of pipe will best compiment this engines power? I also have an O.S. engine, the V01b, NIB. What kind of powerband were these two designed with? Thanks, Brett.

Don't remember the model but it was out 3 or 4 years ago I think, has the blue head of course, and has the tube running from the carb to the crankcase for pressurization. I hope that's enough to identify the engine as I don't have it here in front of me. What kind of powerband were these two designed with? Thanks, Brett.

ther old P5 was very strong on bottom, and really good top, alot of guys prefered the P5 over the newer xs because of the bottom end, that Rex is an animal, very good low end for buggy or truggy, for buggy i like the smoother feeling pipes like the 86 type, just really depends on what your driving and your track conditions.

Default Buggy

Thanks guys. Forgot to mention they would be in 1/8 off-road buggys. I'll be running in the Kansas RC Nitro Series which will be held at 5 different tracks so conditions will vary. I used to know some of what these numbers mean about the dynamics of the pipe but it's been a while, I'll try to remember though. Any further input will help my bad memory Thanks again

I run the Novarossi 9886/short header pipe on my truggy and the Dynamite 086 pipe on my buggy. Both have the P5XS motor. My question would be is there any difference between the pipes I just mentioned? Physically they look the same length, but is there any difference? I haven't been in this hobby long enough to know the subtle nuances of things.

The DYN 086 is a copy of the Nova version. The Nova pipe should run better by virtue of it's thinner walls (supposedly better resonance) but will of course be more delicate. An 086 of nay type should run great on that engine.

Default pipes

I have a RB9886 on my RB 3Port, silver/chrome in color. I also have a RB9886 that has a matt black finish. Difference? Wall thickness? I also have a NIP, Rex 9886/short header combo, silver/chrome in color. I remember buying it now with the P5.

I've looked at the O.S. and it's a VO1b. What did the 1005 and 2060 mean in your reply Brian? What difference might I notice between the 9853 and my 9886 pipes? Still the same pipe choice on the VO1b as you reccomended before? Thanks for the help everybody. Brett

Default Numbers

I've seen 9853, 9886, and 9901 mentioned now. I know the way these pipes are designed have different effects on an engines powerband. For example, what difference would I see between a 9853 and 9886?

Referring to my O.S. , I've seen the numbers 1005 and 2060. I assume one particualar pipe would be similar to one listed above in response to my P5. Does anybody know which ones? I'm curious to the how's and why's of these numbers so I can better understand my equipment.

Short headers vs. long headers? Thanks for any help everyone.

for your p-5 this is a "can't go wrong" choice for you:

http://www.carolinasrc.com/Webstore/...idproduct=3623

Sturdy and works great.


This is a good all around pipe and works well on the newer o.s., grp, and have even seen them on some p5's working well.

http://www.carolinasrc.com/Webstore/...dproduct=11933

Take note of the way it connects to the header.

Just ordered a losi RE-11 for my Vspec, hopes it works good in a buggy. I'm hoping for 10 minute runs and I'm not spending $120 for a 2060, I wish I had the money, but it's not going to happen

if you can find a used os 2050 it is the best pipe for the vspec if in buggy it is what all the pros run os is going to start making them again because everybody wants one also the jp4 will work good with any motor in buggy although with nova motors that seem to have more top then bottom end the jp3 pipe works well.

The O.S. RZB V01b was designed to use the O.S. 2050 tuned pipe. Due to the unique charicteristics of this pipe (bottom end) , and the v01b's port timing, it is the best choice. I hear that the Losi RE-11 is a copy of that pipe and should be as good and much cheaper if true. The V01b engines had problems. They have very soft pistons and wear out quickly. Also they were lacking on power compared to many engines of that period. I would use it as a practice motor and race the P5
