Here is an idea, buy all 3 of them. Decide on which engine you like better, and sell the other 2 used.

It may cost more but at least you will KNOW which engine you like better, instead of listening to what other people like.

All the engines you mentioned I have worked on and yes all 3 have great initial power and tunability but longevity and reliability will prevail with most people. The dynamite engines run great for about 2 gallons and then rapidly decay in performance, tunability and reliability. You will get those who claim I got 12 this or 25 gallons that out of a cheap engine but what most don't know is they fail to mention they replaced the rod several times along with the piston and sleeve, bearings etc etc etc and they end up putting way more money into an engine than it is worth. I have also personally experience several premature rod and crank failures with the SH based dynamites over the years along with other issues and if it wasn't for Ray A in my backyard to hook me up between rounds on some occasions, my race day would have been for not.

As far as the B5, I have modified quite a few of those engines and they run decent stock and run very good modified. Neal from clockwork has a more extensive base of this engine so he would know more about it than I would. I have however done more B3's, B7's, Extech 21's, 24's and CL7's than I can shake a stick at and from my personal experience with those engine's is they always had issues whether it be the rods failing, cranks breaking, carbs having issues or rear bearings coming apart. I have seen the same engines get the carb warrantied 3-4 times on several occasions. Who wants to run 3 races and have to send their carb in for service because it won't work properly anymore? I have also seen many guys get a good life out of their werks engine with very little trouble so it has been a crap chute with Sirio/Star in years past. I haven't heard any major issues with the B5 or B6 yet so maybe they are a decent reliable engine now but because they are Sirio/Star based products, with the luck I had with the past products, personally, I would look into something else. I'm sure Neal would again have alot more info on the newer lines of werks engines as he is a dealer for them and I am not.

Novarossi has been my bread and butter for years. I haven't always been a dealer for them but I have run them since the first P5 was born and it was the Top P5 that I ran. The Nova based products have always been very good and while they may have been an engine here or an engine there with a querk, overall, they have been a great product. Whether you go with the P5, Plus 4 or Toro Nero, you are getting a great product that will last. I personally run the 2010 P5XLT and what a great engine that is. I have never had any issues with it and this is the 5th consecutive season I ran a P5 in my personal buggy. I like the Plus 4 as well but for some reason, the P5 always seems to gravitate into my car. I just like the power delivery and the mannerism's of this engine. It is not too punchy or a crazy fast engine but a nice strong continueous pull with respectable rpm and with the modifications, make it even stronger all around but retains its smoothness. I run a 9901/20 combo with the answer rc 3 shoe with .9 springs and 1.65 gram shoes in my 808 and it feels awesome. It engages really low but has the torque from the pipe and mods to pull it without breaking traction too often but has the grunt to accelrate and clear most gaps with ease. I also love the tuning ease of this engine and with it using the Plus 4 carb now, it tunes easy and gets better mileage than the older design.

To ice the cake for you, I am a Cold Fusion Fuel dealer/rep/team driver so I can set you up with great tuning settings, support and anything else you need for a Novarossi or TQ Engine as I am a dealer for the new TQ 501T which is derived off of the GRP .21 tuned.

Good Luck with your decision!

Thanks for the great post.. which pipe would you run for the p5 in a truggy?

Powerhouse, the Xpe is made by Alpha for Dynamite, same motor as the Z852 green head Alpha.

A true sales man! But wouldn't it have been easier, and not of wasted my time reading all of it, just to have put your last paragraph?:lol:

Well of course he is going to push the nova's that is what he sells. If I sold sh based motors i would pick apart everything else and push what was going to put cash in my pocket.;)

I stand corrected Rex. It's tough to keep up with every single label these days. Looks like a Force based engine to me which falls into the same catagory as the "made in taiwan" label I try to avoid personally but to each their own.

True, but I am NOT selling anything, nor am I sponsored by any engine maker and his post is spot on with my experiences and observations.

Well true to a point but the real deal is I can sell every brand if I wanted to and have been offered by numerous company's to sell their engines and I have tried to be as diverse as I can but in the end, most engine guys will find a company or two they really like and build and sell what they feel is in their best interest based on their personal experience and their customers feedback. I have built and sold just about every engine made in the past 6-7 years and when it boils down to it, I have had and most people have had the best luck and experience with the Novarossi based engines whether it be Rex, Top, RB Concepts, Max Power, JP or Nova themselves. I know it can come off sounding like I am pushing a specific product and I am to an extent but the truth is, I just want to help people purchase an engine that will perform and last to their expectations.

People have the right and ability to buy whatever they want and in the business I am in, I tend to see a few more engines come through my door than most and I have dealt with everything from the guy that bought a redcat for his 11 year old nephew that didn't know how to start the truck even with directions to the full blown factory sponsored pro and with all of that experience, I have was there through all their trials and tribulations and I am glad to be able to share this with you guys and for those who take it to heart have had a good ride with me and those who want to continue to be stubborn will continue to spend money they shouldn't have to in the long run. I race with guys on a regular basis that still buy 3-4 $200 engines a season instead of just buying once. I have a guy in New Zealand that just called me the other night to tell me he finished 4th overall in the Nationals with the same P5 I built for him 2 years ago. I have not seen that engine since I sent it out in 2008. That's pretty darn good for a $350 investment in my book.

I know I tend to be long winded sometimes but I always try to provide as much info as possible without dragging things on tooooooooo long;) Besides, the guys who don't like to read or have the patience to listen and absorb the information are the first ones to F something up and cry they broke their little toy car:cry::lol: Just trying to help a brother out;)

I have tried out several pipes with the P5. I have run the JP1, 2,3 and 4, 9901/21, 9901/20, 9853/21, 2084/21, 9886/20, 2013, 2060, 2042 and others I can't think of at the moment. The combinations I liked the most were the 9901/20, 9853/21 and JP1. The 2084 is very similar to the 9853 so if you have one, no real need to buy the other as they both have similar performance characteristics. The 9853 feels a little stronger all around with the twin chambers but the 2084 does get a little better mileage with the triple chambers so that may be a deciding factor for someone when purchasing one or the other. I personally run the 9901/41020 combo now and have run it all year and love it. I run the answer rc full setup with .9 springs and their new 2.0 shoes which weigh 1.65 grams and the engine with the mods, that pipe and that clutch setup come out of the hole like a CR250 pulling a second gear power wheelie off of a berm. The engine has a unique throaty sound due to the port timing and the length and volume of the pipe and I have gotten alot of "What is that? That things sounds awesome!!!" and they are very surprised to hear it is only a P5 and not some big stroked out engine like the Toro or Cobra.

COnsider the +4 for buggy, softer bottom hit, with tons of top, and AWESOME fuel mileage..

Now that I see Mark has been here disregard all I said, and follow his instruction.. He the man..

Not any issues with any of the modified Werk's I have out there running.... the only failures have been a couple of broken idle screws..other then that the engines have been bullet proof...

Performance, performance, performance.... ....plain and simple the modified werk's are as badass as they come...smooth, powerful and get killer runtimes...Multiple customers reporting back they are seeing runtimes in excess of 15 minutes in Truggy with the mod B5, super easy consistent tuning and did I mention performance ? Out of a corner the mod B5 has torque like a 28 and finishes with a top end pull that will put a modded FMS to shame ! all the while the engine has a very controllable power delivery,very smooth and very easy to drive fast !

You really should try one out, it is the most impressive motor I have ever ran. Z852 Alpha or Xpe) Quality is great, the cranks and rods wear very good. I also see alot of motors and I am impressed. I do not think they are force based, never been impressed with those.
