try rex welch 22racer on here he may have some thnx will g

Hello all. First off I want to say thank you for this very informative thread. It has been very helpful in my decision to purchase a GO motor.

I'm new to the whole 1/8 scale nitro buggy world, and could use some clarification on what would be the best choice motor for me.

I have some challenges to overcome as I live in Okinawa, Japan. The summers are very hot and extremely humid here. I only have access to Cosmo RC fuel (20 and 30%), and OS brand glow plugs.

I don't have a heat gun or electrical power at the track to use a hairdryer for break-in.

With all that said, I could use a little guidance in choosing which GO motor to purchase.

Since I don't have any other track to compare to, I'd say our track is medium size. It's mostly a point and shoot track (no real flowing sections), and short run up to the few big jumps it has. It's fairly hard packed, but with a layer of loose dirt (almost sand-like) on top.

The motor is going in a bone stock Hot Bodies D8 buggy.

I was originally looking into the 3 port sport, but a few people on the D8 forum advised me if I was going to race, to get the 3 port race instead.

Here's what I've learned on this forum...

The 3 port sport has a short powerband, with good spool, and the 3 port race has a smooth, longer powerband. The 5 port has killer bottom and mid punch, and the 7 port has killer top end.

With our loose track, I think the 5 port is out as it may be TOO powerful down low. The 7 port is out because I don't think our track has any long enough sections to take advantage of it's top end.

That leaves both the 3 port versions - sport and race model.

I like the sport version because of what I've read about it's low end power, but I'm a sucker for the Red head and smoother powerband of the 3 port Race model. I think with my competition it'll really come down to the driver instead of the gear (I've seen the most budget cars/engines win because of driver skill), but I still would like to make the right choice, for me at least.

So, given all the info I provided (track condition, fuel, glow plug availability, lack of break in heat guns, etc., what do you think would suit me best...3 port sport or 3 port race?

Although I've read the 0801 or the 086 pipe work great on those engines, I was wondering what the 053 would be like on the 3 port race. Would it give a little more bottom to mid punch, or is the 086 just the better choice altogether. I like the Dynamite 086 or 053 cause they come hard coated, and they are strong and cost effective.

Any insight you can provide would be greatly appreciated.

v/r,

The 053 wont let the engine rev to its full rpm range, and IF it does the pipe will try to stop it from doing so. The 3 port race has enough bottum end that the 053 is not needed on it. The 0801 or 086 is the recommended pipe because the engine has ample low to mid range, the pipe will help it to scream all the way through the power band. The 2047 or 053 will pretty much hinder the full potential of the mill. But like I said before if you will never have the engine on a track with a straight away longer than say 100 ft you can use the 2047-053 if you want, but I would use the 0801-086 no question. I hope that answers your questions.

malik, do you think the 3 port sport with the 086 would have more bottom to mid punch than the 3 port race with the same pipe?

Or would the race model be similar down low, but just better all around up top?

Also, would my fuel brand and only access to OS plugs be a problem?

I'm also concerned about proper break in without the use of heatgun/hairdryer.

Go with the race engine, better choice overall. It should have plenty of punch to get you over those short run jumps. Remember there's other options like clutch bells and clutch shose and springs that can also help you tune how that thing comes out of the hole.

And you're definately going to need something to heat it up for at least break in. You could use a butane or propane torch (just be VERY careful)

With that being said, do you think the EBMod 5 would be good for me since it's already broken in, or would it just be too much for my conditions?. Price is not an issue - I just wanted to prove to folks you don't need to spend $$$ to lower lap times

I also thought of the MassiveMods 3 Port Race Go engine. Looks like it's broken in and tuned from the factory as well. Maybe that'll be a good option for a broken in engine?

I'm not afraid of breaking one in myself, I'd just hate the thought of not being able to do it correctly.

Either of those would more than likely rule the roost at your track

I've heard nothing but good things about both modders and their engines.

The modded 5 port would just decimate all though

Ha ha, I'm sure it will. I just thought from what I've been reading on here that the 5 port, and especially a modded 5 port to boot would be better suited for a truggy.

Since I'm new to nitro buggies (not new to R/C though, been at it for over 15 years), I figured I'd start with a powerplant that had a pretty linear powerband...

There's always the throttle EPA though if the 5 port turned out to be too much, LOL!

Is the EB mod version a turn key solution? As in no break-in, just bolt in and go?



- Paulie

Yessir, shouldn't even have to change the tune on it too much either

I will tell you that the 3-port sport does rip in a buggy on a short track. I race my Truggy with one, I'll upgrade my engine once it because the limiting factor in my lap times. Driving with a slightly underpowered engine will teach you a lot about being a smooth driver with better late braking techniques. Just a thought, plus the 3-port sport engines are hella cheap and easy to tune. Might as well learn on a cheap engine. Plus why pay heaps for an engine if you can't use 100% of its potential?

I would go for the 3 port race. The pinch on them is much easier to deal with then the 5 or 7 ports. Use the 0801, 086 or 053.

i run both 3 port race and ebm5 port and both are awesome engines. i ran the nitro challege 2 weeks ago and i ran the 3 port race motor with go 0801 pipe and it was a rocket there kept up with most the 4,5,6 and 7 ports motors that were running. also ran 5 port ebmod race tuned one there in truggy very powerful. it does work well in buggy with the 0801 pipe and 086 pipe for both motors. i ran the 5 port ebm race tuned motor in buggy for some practice laps and its very quick in there so in my opinion both motors are very good and like some of the others said you can adj clutch for conditions or pipe. thnx will g

Hmm, this is very interesting, as the EB Mods may be a good fit for me. The D8 is supposed to have carbon shoes and it's reported that it's not to explosive, so maybe the good bottom end of the 5 port may be the way to go for me...

I'm a little older, so a turn key solution that lets me actually get MORE track time sounds a lot better to me than playing with Reynolds wrap and a hair dryer, ha ha ha.

In all seriousness though, is it possible that EB Mods can do a break in of a 3 port for me? Or do they offer a Modded 3 port?

I like the idea of the Massive Mods 3 port, but I think it would be easier to get support from the US in my situation.

In any event, do you know who has the EB Mod 5 port in stock?

- Paulie

I'm gathering parts to complete my D8T when it comes in and I'm looking at using the .28 3 port sport with the 086 pipe. Would this be a good combo to use in a Truggy? The track I'll be racing on mostly is med/large with a pretty long back straight.

go to ebmods.com you can order thru him and i think rcplanet has them too. im not sure who else has them right now. also you can send a 3 port to him to do i dont know if he and racefactor plan on doing 3 or 7 ports also thnx wil g
