The New Werks B5 .21 Racing Engine
#946
I ran a RB S7 converted to Turbo head and ceramic bearings. This motor had great top end with the JP3 pipe and good run time around 8-8:30 min mark with a 7.5 carb restrictor. And with the B5 I have not got any good exact run times yet but in this last race i was pitting at 7-7:30 to be on the safe side and with the fuel I had left it will go 8:30-9 I believe. The only complaint I had with the RB motor is a little lack of low end power. Which with the new B5 I have tons of low end and to be honest this motor has never seen a WOT the straight aways at the track I run at is only around 60-70ft. So the B5 has never really got to open up at this track. So this motor is a perfect fit for this kind of track. I already told Mike B. to get me another!!
Thanks for the info! Sounds like you are running on a really, really small track! Once get outside to some of the larger ones start playing around with pipes a little bit. I'm still not convinced that the JP3 is a really good fit for the power band on this engine so I think that changing this might help you quite a bit! Either way though for right now on the type of tracks that you are running on it sounds like it works just fine, so you might as well keep running it lol!

Yea, the bottom end on these B5's is amazing! Before I bought the B5 I was running a newer version OS V-SPEC (2060 pipe)and a sirio CL7B-STI (2013 pipe)and I liked them a lot but I had to run 1.1 springs in my d8t truggy and I still was not happy with the bottom end, so ended up running my WERKS B3 which has a lot of bottom and it was great! Lcked a little on the top but it was better on the bottom than the vspec and the sirio. Then I got a B5 and WOW!!! The bottom end is insane! I even took the 1.1 springs out and put in 1.0's becasue it had SOOO much bottom! And the top end is awesome.. This to me is the best truggy engine I have ever run. Cant wait till the new WERKS pipes come in so I can pick up a couple!!!!

So far I am pretty impressed with the B5 also. I have raced mine one day and am still breaking in a little bit, so I wasn't a mad man on the needles
I am running the motor in a Mugen MBX6 with 1.0 springs on Mugen Aluminums, a 14 tooth bell and the 2013 pipe and header. I was getting about 9:30 minutes runtime on an indoor track. This week I will be moving to the Werks 30% fuel for the first time. I can't wait to let the motor eat. I will also be breaking in my friends B5 for use in a Losi truggy, so I will let you guys know how that goes. If anyone racing at HCRC in Danville Indiana this weekend wants to see one of these motors in action just find me.
Thanks

Nasty I think that is the best pipe I have seen with that motor and ebay has the AXE ROSSI 2050 for $59 Trust me guys this is the pipe for this motor. I have seen alot of B5 motors run and Nasty had the 2013 in his car and the AXE 2050 kills it.

cant wait to run this motor. i have helped a couple of guys already with tuning and pipes and so far the 2060 was VERY good. the 2050 is good but the 2060 really gave this motor some top end. i've worked with alot of motors and tuning,run time,speed,lowend,great idle,smooth power,low price put this motor way out in front of more expensive mills. we also found the p3 plug was more gooder than the 97t.lol
