Is the novarossi p5xl faster than the plus 4?
 
Hey guys i was just wondering which motor was faster?I have the p5xl in a 2.0 buggy.And is it actually faster than an o.s speed?I just wanna know because a guy races the same buggy but has the o.s speed.

Probably have better luck with this in the engine section buddy. You can just ask a mod to move it for you I'm sure.

I put it here because alot more people are in this section than the motor section.:nod:

Ok, fair enough, but the mods will probably move it on you anyway since it's engine related. I don't own either but have close race buddies that run both. The P5 has been around for a while with very little changes and is rock solid as far as durability and has a really great bottom end. It's a workhorse motor.

The Plus 4 is a newer and IMO more advanced engine with a linear powerband and better runtimes. I run a truggy so If I was choosing I would go with the P5 for price, bottom end, and durability. But, most of the racers I know prefer the smooth power and run time of the Plus 4.

That's all the better I can do on these. Like I said I don't own either but I see both run at least twice a week. I have ran them also in their buggies and have helped them tune them in, so I'm not just shooting off at the mouth here.

Well thanks for the info man i really appreciate it.The new p5xl is the one that uses the new style head like the plus 4 and the block looks the same.:)

This is coming from someone who runs a P5XLT on a regular basis.

P5XLT; C6TGC plug; Byrons fuel; 41021 manifold; 2084 pipe; on a Losi 2.0-T

Will go 10+mins runtime on *most* tracks and has been as high as 14mins.

It's close enough to the +4 mileage wise to come down to driver error.

For buggy...I'd stick with the 4. In truggy; without a doubt I'd pick the 5 everytime. Much more bottom/mid and doesn't give anything up on the top.

The 5 works real well on buggy too and will get mileage numbers. You just have to be a little smoother with your throttle finger :sneaky:

There's no great advancement in technology with the +4. It's a just a calmer engine overall.

Though the P5XLT now has a black crankcase, the castings are different.

The carbs, rear bearing *size*, conrod and other misc. hardware is shared.

However, the crankcase, piston/sleeve and crankshafts are different between the 5 and 4Team.

Personal choice, but for buggy the 4 is hard to beat.

Buggy: +4C-Team, 9901, 41021

Truggy: P5XLT, 2084, 41021

Since you're already running the P5 in a buggy, you'd probably be a little disappointed if you swapped to a 4 now. It's smoother, but also a lot calmer in the mid/bottom ranges where the 5 comes on like a torque monster.

Honestly no way I'd put a JP-x on a Novarossi.

Odonnel fuel is fine ;)

If you want to see your P5 come alive another notch try a Nova 9853 or Dynamite 053. The JP1 should be putting a damper on your top-end and definitely isn't doing anything to help in the fuel mileage dept.

Seriously though, the current P5 is fast :D You're not missing out on anything power wise :cool:

kman16jr 10-30-2010 10:49 PM

I can buy the pipe for like 55$ bucks at the shop i work at.The dynamite ones are quite nice for the price.:)Plus employee discount.:D

merdith6 10-31-2010 12:40 AM

yep
 
The above points are true, the p5 is really powerful but not quite as much top end as a plus4, but the plus 4 is a bit mild throughout the powerband...

dcracing 10-31-2010 06:34 PM

The new P5 has more low, mid and top than the +4.

9886 is the way to roll :nod:

How are you guys finding the output compared to the old P5s? I loved that motor. Running an older Picco XP which is/was basically an early version (long stroke 5 port motor) with the long NR smooth mugen header on a brandy new 9886 and it is a complete animal. lol Ran it yesterday and I was very impressed. Not sure what the mileage will be in the end but I love those long stroke mills.

I'll be shopping for a new mill here shortly for next season and I'm again interested in the P5. How does it stack up to the current to the v-specs and such (not new speeds)? Pretty cheap money for a solid mill.

I guarantee u will not be disappointed in the latest version of the p5

Truggy - p5xlt , 7mm , 2084ss/41021
Buggy - p5xlt , 6mm , 9901ss/41005 or 41021 or 9886/41021 if you want ripping top end power !! :nod:
