pipe
 
Mark, just try a new pipe. I have alot of pipes you can try at the next race. I love my Fusion mod B3 with TKO Bearings and Novarossi carb with a B-Mods head. I just run a 086 pipe and got second at the King of the desert race with it at ET and that track has a 120ft straight and there was not a motor out there that would pull it.

Now you're talking. It's what I want to hear I guess.

I know what the B5 does and I like it. I just drive my truggy different than my buggy. My truggy may as well have a zip tie on the throttle. Not the case with the buggy.

So there is a B7, and a B7 Pro-C?

Marcus, you almost won that!! You looked good.

Markhat, to get more top run either a 2057 or 2013pipe. The 053 actually on these engines brings more on the bottom and falls of on the top. If you cant get a 2057 or 2013 then even a 086 pipe will be way better than the 053. I also have a B7 and it does have more top but it also has a lot less bottom. If you dont need a lot of bottom then the B7 will be great for long tracks. If your track is that open you can also go up on the clutch bell 1 tooth or even 2.

alright..I'm going to try a top end pipe and see. Thanks for all your input folks.

pipes are cheaper than b7 pro's :nod:

All I can say is WOW :D !! The B5 in my RC8B preformed outstanding this weekend in the 15th Annual Lone Star Classic in Garland Tx. Did not get a chance to make some good fuel miliage runs do to me just getting this motor last week and very little practice but I did manage to qualify 7th in the A for Sportsman Buggy but broke an upper turnbuckle around the 35-37 min mark of a 45 min. main. I believe it will go around 9min with a the JP3 pipe and a 7.5 rest. This motor has tons of low end!! I allready placed another order for a B5 for a back up!!!!

I keep telling you guys to try a 2035 pipe. I think youll be really suprised. I raced sat. with one and being the rookie I am, first race season. I could hang with anything down the straights. Its very torky on the bottom, good mid and good top.

I'm running a 2035 with the B5. When it stops raining so I can get to the track and finish break in, I'll give her a good romp and see what she can do:cool:

Sorry, been a few days since I had a chance to get on here but regarding the 2013 and 2057 I would not consider them top end pipes. They are just pipes who's performance characteristics are well suited to this engine. In any case please let us know what you think once you have had a chance to try one!

Hey Lance, thanks for the feedback on your engine! What were you running before and how does the performance and run time compare if you don't mind me asking?

Regards,

Ron

Please let us know what your thoughts are once you get a chance to run it.

hdcruzer, thanks for the tip on the pipe. Looking forward to getting some more feedback from others on it!

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!!
