Run-in on the plus 4c...coming along very well...i think it better than my other one well reg plus 4

+1 on this question. I'll be ordering a P5 in the next couple of weeks and would like to order the pipe I need with it. I currently have an 053 and JP2. I suspect that the 053 is probably a good pipe for it and hope that will be sufficient. I'm wanting 10 minute run times and a nice, smooth, linear power band.

9853SS/41005 makes great power through the whole power range while getting pretty good mileage , 9901SS/41005 makes ok power but gets great mileage . If you want more low end on either pipe get a 41021 header .

The new 2084ss should be the best of both worlds


And if you want stupid amounts of power and insane top end try either a 9886/41021 , dynamite 086hs or ofna 086 with 41021 header . Another good one is a 2013 pipe

I just picked up a couple of these...I have heard good things about them. So they are good for a little extra time huh ?

I've tried a quite a few different pipes on my P5XS and the Dynamite 086 works the best. Crazy power thoughout the whole range and 10 min run times. I made a mistake and bought the recommended 3005 pipe but it hurts performance in my opinion. Dynamite exhaust systems are inexpensive and just as good as anything else out there....

Yes. With the Nova Exhaust Cooler, I noticed a 45sec-1min Increase in Runtime. Love mine!

Can you put a turbo plug on a n21r? How much to add the plug? I like to run 20% nitro, what kind of power can I expect?

Yes you can , part # 28002 , minor power increases

More power increase in crank upgrade

Anyone here knows where I can buy a replacement crankshaft for a max power c5q engine? or any crankshaft for Novarossi engine that is compatible with this engine.

Thanks.

Man, thats great. now i want one.

man, I cant see how peeps are hatin' on the 9901ss pipe! I ran mine yesterday with a 41021 on a 6.5mm plus4 C and WOW.......sooooo smooth and gradual, nice linear powerband that had plenty of topend for our backstretch and plenty of low end to clear all the runup jumps.......awesome runtime.......I found my buggy pipeset for the season, no need to look/test any further

Novarossi power baby

I have a 9853ss with a 41005 header coming for my truck!

Odonnell 97T plugs ROCK with 21-4!

ditto

Quick question. I got a few Nova C5T plugs at a steal and was wondering if they would be too hot to run in my +4C. I live in Florida, so the humidity is a little higher. Also, I'll be running 30% Byrons.

Looks the same as the 9853ss, but better runtime. Internal changes to the baffle?? I run the 9853ss with the short round header and it rips, but fuel mileage is not as good as the 9886 with the bent header. About 8min compared to 10 with the 9886. I might try the bent header with the 9853. But the 2084 has me curious.....Bet it's perfect for my p5....

Anyone please!?
