The OS 2050 will cut the top end off and give you more bottom. The 2060 is a much better rounded pipe great bottom, top and fuel mileage.

No. The re11 is the os2050 clone. That pipe is ok on the js but the 9886 is much better. The losi re10 is completely different. The os2060 doesn't fare well on the dyno. Some claim the re10 is similar to the 2060 but side by side you'll see they are much different.

I was referencing your previous posting since you mentioned a Re10 has a similar power curve (9886) but with a better top end (Dyno King). Amain is listing the Re10 as a 2060 ?

I have both pipes the 2050 and 2060 the 2060 gives more mileage with a smoother power curve better top end in my speed engines yes different animal but since you stated the RE11 was the new King I mentioned the 2060 because on a OS engine its a better package (speed) then the 2050 thinking these engine have similar characteristic

Since the Alpha is back ordered I was debating on a JS. since you posted Re10 (Aka 2060) as the dyno king it got me excited since I only stock pipes for OS engines I would save some $$ .

I'm at work and using my i phone which is a pain to sift thru the posts. I may have posted it wrong but i meant the RE10 posted the best dyno graph so far, not the RE11/2050. Ed has recommended the RE11/2050 since it is on the efra list of pipes that can be used at the worlds. The 2060 doesn't work well on the JS if you look at the dyno results. I hope i didn't post it wrong earlier.

Man this engine must have tons of torque if it is a monster with a high speed pipe like the 086.

Bruce53 02-09-2010 01:29 PM

If I can get money to grow in my wallet , will definitely have one for this race season ..................

dennis has one now, we will see what he has to say once he gets an 086.

bigjayjay1 02-09-2010 03:18 PM

with all these new motors its like being in a candy shop the only difference is your wallet is a lot lighter.

All right that’s what I want to hear 11 to 12 min run times with a 086. Just bought the dynamite 86, we will see how it works out this weekend at the track.:nod:

single2372 02-10-2010 04:31 PM

I know this is the JS thread but does anyone know if Edd still has Go engine parts, just asking because I bought the fully mod motor from him last year and it was my favorite motor all the way up till the rod pin sheared off the crank. I wonder if I can still get a crank for it.

Give him a call at his shop tomorrow and ask him. 570-779-0646 Thats the only way to know for sure if he has any.

jbright33 02-10-2010 05:18 PM

i know like a month ago he didnt have any go parts but he might now try calling him tomarow

hambone 02-10-2010 06:19 PM

The JS crankshaft and p/s/r might just work in the EBM5. Ed can tell you for sure. Other than that i believe the only go parts he has are head shims.

single2372 02-10-2010 07:10 PM

Thanks for the Information Pennsylvania Posse, I will Call Edd in the Morning . http://i230.photobucket.com/albums/e.../rcpics254.jpg

ouch that kinda bites

shanty140 02-11-2010 07:53 PM

Hello,

I am almost for sure getting this motor but because of how new it is I am still a little unsure. From the sounds of it so far it seems like for the money there is nothing that touches it. Only things that worry me is how long this motor will last. So I was wondering how many gallons has people put on there motors how does the wear of the motor seem to be. Does it seem to be able to last as long the V-Specs, Nova +4, etc with normal engine maintenance of coarse?

Thanks for any reply's.
Shawn

FrankBlack 02-11-2010 07:58 PM

2 gallon mark, everything is still perfect, very happy with this motor so far. Coming from running ninja jx for the last couple seasons, i prefer the JS even if they were the same price.

smokinu 02-13-2010 07:56 PM

here is my buddies js engine running in his losi 2.0t (single2372)
i was driving his truck in the vid lol.

anyways, even with the 086 pipe this motor is very mellow on the bottom end. its also VERY smooth!

i am running one of singles eb mods go tech in my truggy right now with a go tech 0801 pipe and the thing is a rocket out of the hole.

but here is a video (still working on the tune, its still needs some more fuel to be perfect.)

Thinking of getting myself a new engine for my truggy... Im stuck between the ninja and Js....

What are the differences you guys have noticed between the 2 engines?? I know the ninja is OS quality, can the js be compared to the ninja as far as quality goes, or will I need to perform engine rebuild sooner?? What power differences are noticed, and how is the consuption between the two.

I currently run a picco p7-evo3, and it has great power, and I manage to get about 11-11,5 min runtime..... Will the upgrade be a big difference to the picco?

your asking the ? the wrong way it should be can the ninja compare to the js lol. na personaly iv never owned a ninja but guys who have say the js is stronger and smoother and gets the same to better run times. as far as rebuilding goes its all in how you take care of it. as far as the modding the picco only thing id have done is balancing cause last time i ran one of those the rpm's were all over the place.

Shoaf85 02-14-2010 11:05 AM

Good things are coming from these motors. Unbelievable performance at a great price and good customer service.

Whats up Hambone!!:tire: Would you happen to know if Ed did a dyno on the 2013?? Thanks.

Hay Jbright33 just wanted to thank you for the info and pointing me in the right direction. I had the JS on the track today in my Losi 2.0T with the Dynamite 086 and what a beast this thing is. No problem with getting 11-12 min run time, with the 7mm carb insert. The JS is so smooth on the low end with loads of power and screams hard on the top end.
I do own a Ninja jx21 and the two motors don’t even compare with each other. Both have around same run times but the JS has way more bottom end ready power, temped out at 190-220.
I will be ordering another JS
Ninja jx21 now for sell.

smokinu 02-14-2010 10:13 PM

i will give dennis that, he pulled a eb mods go tech (with out modded crank) and a matched pipe, down the straight.

this motor is VERY impressive.

Mr Judson, i'm not sure. Throw it on and do some track testing. See you at motorama?

Yesir!!! See you there:tire: I think the JS is going to represent at Motorama!;)

hambone 02-15-2010 03:27 PM

Right on! Putting the finishing touches on my truggy tonight. I'm not able to race, but Ed is running my truggy. See you there.

jpalessi 02-15-2010 03:43 PM

JuD,
No dyno testing with the 2013, but a couple team guys have reported it runs good! tons of bottom, not as much top, good run times but not as good, sounds awesome! typical 2013 characteristics. The JS is not so pipe sensitive so try what ya got! ;)

See you there Hambone. And Joe thanks alot!! I will have my 2013 at practice. I will put the EB Mods pipe on after a few runs.

I know for a fact how well the 086 pipes works since i ran my buggy with a 9886 nova pipe. It's a killer. Very curious to see how much better the RE10 losi will be. Dyno shows it to be alot better on top, mostly equal everywhere else.

toobad4u 02-15-2010 06:56 PM

All this talk about how great this motor is has me interested. I already have a EB V-Spec, so I am looking for a motor for my truggy now. Is everyone talking about the motor in it's stock configuration, race prepped, or full mod? I am leaning toward the race prepped, that way it is checked, and ready to go when I get it. I hate breaking motors in.
The only pipes I currently have are Jammin JP2 and JP3. Will these pipes perform well with this motor, or should I get the 086 I see everyone talking about?

Thanks for your time,
Stephen

Stephen, All EBMods engines are check over before they leave EBMods, even the box stocker. As for pipes, the 086 is the best overall preforming pipe to date. The JS is not very sensitive to pipes and seems to run well with many different pipes, so with that said try what you have before you buy, but if you buy go for the 086. ;)

khaliffen 02-22-2010 01:07 AM

I took my Fully modded JS out for a spin yesterday. It was a pleasent surprise. It has a smooth powerband, which made it easy for me to control power. With 7.5 insert it had a competetive fuel economy and on the straight it seemed to have just and inch more top speed than the average engines i was racing against (top line RB's and Novarossi's). However, the straight was fairly short, so it was difficult to say for sure. :smile:

One problem i noted was that the carburator didn't seem to move so smooth. I compared it to some of my older engines (a Go and a Novarossi) and it was clearly more tight. It was the same for my buddies FM JS. Any ideas or thoughts on this experience? :confused:

jbright33 02-22-2010 02:05 AM

my js's ran great this weekend at motorama. also congrates to Matt McCready winning open truggy with the js...:nod:

blktransam 02-22-2010 05:33 AM

well just signed with EB mods for 2010 :)

I dont know what JS(full mod, or stock)engine that was in open buggy A-main I think on the track at Motorama but that thing was moving. Everybody that I talked to that I saw with this engine love it. I talked to Ed Bridges also and the 086 pipe is the best pipe for this engine. He stilling testing with other pipes but that is the best so far.:nod:

chim13 02-22-2010 09:00 AM

I just want to say thanks to Ed for making a great engine:nod::nod: I ran the full mod in buggy and the race prep in truggy and they both were super strong and smooth. Also i would like to thank Joe Alessi for make some great products to support the engines. Both guys are class acts and they products are beyond compare. I am proud to be on teams that have products at the top of the game. If you have not seen these products in action you should check them out, you will not be disappointed. Thanks again Ed and Joe

jmpn02 02-22-2010 09:41 AM

EB JS FULL MOD ROCKS !
 
+1 The EB mods JS engine is a contender! Ran the full mod in expert buggy @ Motorama and could not be happier! Only regret is that my driving did not match the perfomance of the engine and car. Got to meet Ed and Really was impessed that he is a racer just like us!!! Not just a buisnessman trying to push a product. Way to go ED you hit a home run with this engine. Thanks again.

RMKinWI 02-22-2010 11:07 AM

Now if Amain would get the Race Prep JS in Stock I could buy one:cry:. Can't justify the full mod.
