I Just bought Hyper7 PCR Minus Engine
And this is first buggy. I have been running RTR-trucks For 2 years
I had these Engines in Mind And can't make up my mind!
Any Input would be apprecieted.
Purpose Is Track no Bashing!

what is it for bashing then c5 racing the p5

i would like to know where u can get a C5 from for $214????

s7 RIPS!

Im with Kyosho kev.... [X(]...$214

i have the rb concepts S7II, and it is a raging beast of an engine. probably not enough torque on the bottom end, but screams on top.

the P 5 is an awesome engine, only problem is the pistons and rods are crap in some of them, maybe a bad batch.. i have a P5 and ive shattered 2 pistons and 1 rod, in as many runs,, .. I have replaced the piston and rod with one out of an old hyper 8 port and its working fine, the piston is a smidgen smaller in bore but with a little pinch works great.

Most people at my track run rb's because of there reliabilty and there speed[&:]

Are the new P5 Piston and rods stronger?

Why limit yourself to trashy engines. Think Picco P7-R. The FASTEST ENGINE at the worlds.

Where can I find the P7-R
I can't find on Web any links and how much?
Thanks! Kevin.

for the same reason..why get a P7-r when a vspec will walk it all day long?

out of the engines on ur list..i would go with a 421B...RB's pull good mid to top..but are sensitive to clutch adjustments

Wow where are you getting those engines going for those prices? I would go with the P5 , amazing engine. late

i seriously think all you guys with your x-specs are overating them big time. you think they are the best in the world. grahma is right the p7-r was the fastest but to bad about technicalitys but we couldn't have ofna winning now could we.

i know you like your P7-R Alex as i hope i will like mine once i start using it
BUT the P7-R was in the CAR that was going around the track the fastest at the worlds. it wasn't the fastest engine at the worlds due to Yannick restricting the amount the carb could open & as such he was noticably slower on the straights than pretty much all the other cars as can be seen on the many videos of this posted up all over the net at the time!

the hyper was the buggy he was using but all you hear is Mugen Mugen Mugen when people talk about the Worlds and also its RB RB RB everywhere! so people only read the results rather than actually look into the facts & reasons behind things[]

Is the Picco P7-R available yet in the U.S?
Kevin.

I haven't had any luck finding info about the P7-R myself, not that I want one, I was just curious about its specs. Anyway, if you decide on the P5, I have a brand new in the box Rex P5 that I'll sell for $220 shipped if you're interested.

THe P7-R is possibly an Omega engine over there (still Pico just a different brand name).

as far as i know the Omega version is available in the US already but they're still waiting on the Picco P7-R
its still going to be called the P7-R and i believe the hold up was because they have been waiting on a new spec crank!

a quote from Ron Hopkins lifted from The Grid
that should explain the delay

The poll says S5 not C5. S5's are ~$200

I think you should consider the JP FX B5-N Stock. It's in the ~same price range as the other motors your looking at. ~$300.

I Got The Novarossi Top T421B Which pipe should I go with the JP-1 or JP-2?
I Got it from PDLracing $242.99
Thanks for all the input!!!

i use an RB 9886 with long manifold on both my 421B's & they scream like a raped ape
