Which Racing motor???

[ObiWan]

I am looking to buy a new nitro motor my OS RG just blew. I am looking for something competitive for racing. But also looking for reliablity. I have been looking for P5's, WS7II's and also RB S5's. Which one would be best or am a missing a good motor to look at?? Thanks alot in advance, Obi

OK if those are what you are looking at, I will add a few in that price range.
Collari B7(carb sucks though)
OS V-spec(some had bearing issues)
MR Ninja

Of all of them the P5 and MR Ninja would be my choices, followed closely by the Vspec and S5. If you use a Novarossi carb on the B7, that would be the best bang for the $$$.

I have read about the STS .21 being a very good mill for the $$$ as well.


What size track do you run at and are you going to use a pipe you have or get one to match the engine?

 

[ObiWan]

I run on a track that is wide open with 200 ft straights and small tracks that are tight with 100 foot straights. I will probably buy a pipe to match the motor, I'm sure my hyper 8 pipe will restrict most of these motors. Probably go with a Jammin pipe. Obi

Ok sorry about the post earlier on the large track, the straights are 165 ft. not 200 sorry alittle far fetched. Obi

Also what about the V-spec OS or the P7R evo???? THanks agian Obi

What is the mill going in??
My choices for a nice race mill would be either the Nova P5 or WS7III...
The Mr. Ninja are fairly new, and I havent read anything about them being any better than the mills listed..

 

[ObiWan]

They are going in my Hyper 8. And is there a difference between a P5 or a P5X???? Also which one do you think will hold a tune better??? Thanks, Bryan

 

[ImBroken]

I have a P5 in my MBX5, and it holds a tune beautifully.. I can't speak for the WS7III. I believe the P5X is just the new improved version of the P5.

 

[ObiWan]

Thanks very much for the info so quickly, what pipe do you suggest or will my standard Hyper 8 pipe be ok??? Thanks again

The P5X is just the new P5, the mid range needle has been removed. I run a P5 in my truggy and a JP mod in my buggy. The JP is a Novarossi based engine. I know a couple guy running V-Specs and they are good performers as well, they do seem to get good mileage. I've also heard from a couple others running the Ninja that the thing gets awesome mileage. I think Zandor is running the WS, maybe he'll chime in on that. I also just ran a JP-3 pipe on my truggy this weekend for the first time, WOW! Crazy midrange, it was perfect for the track I run.

 

[ObiWan]

Thanks very much for the timely responces, so I couldnt go wrong with either the P5 or the Vspec OS it sounds like.

 

[ObiWan]

Any other input????

 

[vbgagnon]

OS has corrected the bearing issues.

The ws7III is insane it seems like there is no end to the power
The p5 is a stump puller

I think anything you go with is going to do you well and last a while.

As for the pipe, I would change but depending on the engine you go with we can recomend a pipe to best suite the engine.

 

[ObiWan]

I will buy a motor tonight, and when I do Ill chime back in about which pipe, thanks for the info

 

[psunitro]

Rember to leave a good $70 for the pipe header! I saw you price "limit" on one of the "other" sites!

 

[ObiWan]

I willl defenatly keep that in mind about the pipe.

 

[ObiWan]

I ended buying a Nova Rossi P5X with an extra OS v cut cooling head, 2 jammin JP-1 pipes, 4 headers and one is a Nova Rossi shorty header for 265 from a friend. I just couldnt pass it up, i has only had 2 liters through it so far and is getting stronger every time. Bryan

 

[jetmechG550]

It takes about a gallon for the P5 to come into it's own.

 

[ObiWan]

Well heck its not even broke in yet!!!!
