friday i ran it in my buggy and i was getting around 10 min a tank with the 053 pipe and an OD 99 plug and it was temping around 240. i love this engine, it even worked fine in the truggy, i was running against 300+ dollar engines with no problem. the BF is worth every penny IMO. romax (my dad) is getting a modded one after seeing how well mine performed.

i also recently got a nova .21bf, but i only have 2 pipes right now, a jp-3 and a os2050, which one of these pipes would be better to run on it??

from my own experience the bf runs best with 086 no doubt especially stock. iv seen with patience in tuning almost any pipe ran on a bf. jp3 will work although will run bout 20 degrees hotter normally. 2050 seems like it wouldnt be bad yet a little harder to tune in

I would jump in one of houstons threads with that for sure. im sure the right cuts are on that to lean on one pipe better than others. altogether tho for $30 id grab a 086 polished dynamite pipe only and match it up with a short header. 086/shrt header on bf is the ticket. this will also result good fuel economy

i wouldnt get polished, it looks like crap after the first time you use it, i have had both and the hard coated ones are way better.

polished is cheaper. cook that thing in coolant&polish maintains easier than hard coat. i got 10 pipes some are hardcoat, some polished...all get dented worn so i go economical more than not

yeah i have a JP3 and 053 hard coated that i have been using for about a year now and they still look brand new and have no dents. but i also had a 053 polished and i used it for 3 months and it looked like crap and i got i few dings in it so i think i just had a bad luck with mine and it has just turned me away from them, but all pipes work the same and like you said polished is cheaper so either way it will do the same job.

i would try the 2050 and the JP3, before buying a new pipe. also IMO the 053 pipe is great for the engine, but i run on a little tight of tracks not extremely long straights, i was getting over 9 min a tank in my buggy.

right now the pipes i have in my 2 cars are both hard coat although if i was to buy new today and my sponsor couldnt get me a good deal i know that ebay has polished dyn 086, pipe only(no header) for $31(it used to be 31 at least). Also power racing has an 086 with long header for about $35 on ebay. On several of my nova&/based mills iv used the power racing with a cheapo short sportwerks header(off an old sptwks rtr i believe)and they ran so much smoother in powerband with exeptional runtime.

If you can afford..nothing can result quite as well as a nova/rb 9886 with 192mm header. This pipe is actually made for nova/rb engines. The 086 line of pipes are great alternatives, sometimes more durable as well.

what iv found with cooking hardcoat pipes in coolant they loose there shiny finish and normally cannot be restored to original finish...as do polished yet still with a little mothers polish im always impressed with the results of polished pipes when done and cleaned.

This past weekend ran this engine at rcpro.

used a dynamite 007 pipe HC
odonnel red plug
sidewinder world 30% fuel
Rcpro hard shoes and ofna .95 springs
Stock shimming
7mm restrictor

Car handled great plenty of pop and top end. 11 minute run times were noted. had a buddy drive it and he said it pulled as hard as his toro neo with insane top end power.

notes on the pipe feels about the same as the 053 with a little bit more runtime and is alot quieter, my pit guy mentioned it was very hard to hear my car as it was so quiet.
