mods???
 

are moded engines worth it , and who does the best job??:(

RE: mods???
 

I would say if you are a pro yes but as a club racer I would not spend the money unless you just have to have it. The engine or the buggy is only a small part that it takes to win races and the driver is 90%. Just my 2 cents.

RE: mods???
 

"pros" dont even run modded mills. look at the worlds. standard vspec with the new lightweight cooling head.

and also 1,2,3 at the US nats on standard vspecs

the only time when pro drivers do run something different to whats avaliable in the shops, is mainly for research and development work.

Also when you say modded mills, there are two types.

1. is where the mill is modded by factory. e.g Rody Modded C5's and JP modded B5N's. In this case usually there is more than just doing some sleeve and crank work. On factory modded mills, you may get extras like ceramic bearings, better rod, hardened crankcase and crank, better quality seals and carby etc etc.

2. then there are engines that are modded by backyard operators. I would stay away from them.

If you do go for a "modded" mill, go for a factory modded mill as there is more to a mod than just taking the sleeve to a dremel, factory mods also make it last longer and hold a tune better. Also thier sleeve work is all done accuratly to the micro millimeter with cnc machining.

RE: mods???
 

The other reason to run modded engines is so you can run a cheaper engine that goes like a dearer one. I'm running a modded motor at the moment because i want something that ran just like my v-specs but with out buying a third v-spec. I'm happy with what i have, which is a modified 7 port go-tech engine, which performs as if not better then my v-specs, but it comes down to the how it goes in the long run, it cost me slightly less the a v-spec, but if it dosen't last then it was not worth it, i guess i'll find this out in time, i have about 4 gallons on it at the moment and its still going strong, but i'll have to see how its going after 10-15.

RE: mods???
 

If the track is loose or anything short of gigantic, don't even bother.

RE: mods???
 

if the power is smoothe its not really possible to have too much its all about your trigger finger. in saying this there are lots of people who just point and shoot as such, but if you can control your self power is good even on a slippery track, (i am probably far from the being a real good driver, but i'm good at controlling the throttle, at least).

I must say i don't see the need to make a v-spec or a c6 etc go alot faster but i can see the benifit in making a bottom end motor go better up top or a top end go better on the bottom, or to improve run time and reliability.

RE: mods???
 

also what have you run in the past and what are you chasing.

RE: mods???
 

nothing as too much power? that why electric worlds most people use only 11 or 10 turn motors. there are much faster motors like 6 or 7 or 8 turn, but no one uses them. why? they are TOO fast.

thats when the marketing spin comes in with the modders, saying that it will give better run time, more linear power, and its faster aswell. ummm yeah right. :eek::eek:

and wow jeff already up to 4 gallons in 3 week? you must calculculation of gallons must be different to everywhere else. :eek:

RE: mods???
 

Do we really know what they run or are all the engine taken down and checked after the race? I would think they get the cream of the crop!

RE: mods???
 

no, not in 1/8buggy.

chad has said he runs standard OS engine. i tthink some of them changed to TKO bearings (they are sponsered by them) . so we can only take his word for it. having said that, there are times when they do run something different, but thats what R&D is about and those changes will flow onto the mainstram. Like the new OS lighter cooling head will.

RE: mods???
 

Is the spec T OS latest version with the light head? All so are they suppose to have less bearing problems? Being I am a novelist I think I will be happy with my OS RG for club racing. I know it is not any where near the engine the VZ-B is.
Thanks

RE: mods???
 

there is only 1 vspec at the moment. (there is a JP version though)

the "T" just referes to the Turbo plug. which they all are anyway, that why its more commonly refered to as just V-spec

RE: mods???
 

My mistake, we actually measure in litres, though i try to convert for the masses. it has 4 litres (1 gallon) approx.

don't know anything about electric so can't really comment, but, what about run time and low speed driveablity, six turn motor would be notchy at low speed wouldn't it?

better run time, more power, and faster. very possible if you can increase efficency. whats the difference between an rg and a v-spec? efficency?

RE: mods???
 

The RG is not near as hot at the V spec. All so cost about 1/3 as much as the V spec. Here are two links with the specifications for both. But I have been told by many the RG is a very good reliable club race engine. I will find out shortly.

RE: mods???
 

The difference i was refering to was efficency, the v-spec is better right through the power band and uses less fuel, why because it is 3 times the price and is more efficent at converting fuel into power, tighter tolerances, more detailed porting, lightened and balanced parts. that is what you pay for. only way to increase power without increasing volume (either engine or fuel) is efficency.

RE: mods???
 

so you think if you sent your modded GO engine, to the engine techs at OS or Novarossi they can do anything with it? Or you think your engine is already maxed out in terms of what it can do?

On the same note, why mod something from OS or Novarossi thats has got 1000's of hours of testing and development, by someone who looks at it for 5minutes and then whips out a dremel.[&o]

even if they can get the first mod perfect, then can they replicate the same mod for the next engine? i think not.

RE: mods???
 

no offence mate, but you have absolutely no idea what you are talking about with this porting stuff. of course you wouldnt trust a modder that just hacks away with a dremel. but the people that actually know what they are talking about work wonders with these engines.
the pros measure port timings with digital measuring equipment, then enter the information in specially designed computer software which then gives them a readout of the parameters which can be changed.

babagnush, i would get it done...but only by someone who knows what they are doing and with a good rep. may cost a little more but worth every penny.

RE: mods???
 

and what is this magic computer software? was it desinged at IBM? hahaha.

u know Novarossi and all the engine desingers use CAD to desing thier engines anyway, then let teh CNC machine do its magic

you say they dont use drmel, so these modders map your engine on a computer, then CNC machine it? hahahaha unlikly for $50 hahahha:D

RE: mods???
 

and no offence nedMX, your a hond. i let you waste your money. go ahead hahahaha :D

RE: mods???
 

Yes most know the two ways to increase performance is to either make it bigger or make it more efficient. I learned this over 35 years ago when I picked up my first wrench. Sorry I over looked what you where getting at in your post and was just trying to help. That is what I get for being up so late. ;)

RE: mods???
 

The power is controled by your finger and if you know how to use it then it can be an advantage. It does however leave less room for error and the extra power might not be any advantage at all depending on the track they are racing on. If you have great throttle control then more power wont hurt depending on where it comes in on the RPM range but that doesn't mean it will give you an advantage either.

I haven't read to much about engine modding but I'm pretty sure you can change the engine timing a little. I don't think it will give you more power but you can change where the power comes in on the RPM range.

I still don't think modding would be worth it. Power is a very small amount of how fast your lap times are anyway. If you want power for anything it should be passing... if you can beat someone coming out of a corner with more bottom end power then it makes passing a whole lot easier.

RE: mods???
 

Read post number 6 in this thread, i made my point about modding to shelf engines there.

do i think OS and Novarossi could get more out of my modded go-tech engine? yes. It comes down to how much time and money your willing to throw at it.

I got my engine modded for a particular reason. Because i was chasing something that went like my v-specs for about the same price. So i got a go-tech engine which was cheaper and had it modded. I'm know little about modding 2-stroke engine, but i'ld say the main difference would have been the improvements to the bottom end from standard. So i have got what i was after performance wise now, i'll sit back and see if it was money well spent or not. If it doesn't work out for me, i'll try something else, say an RB or the likes (if an rb c6 was even close to the same price in this country i would probably have one by now).

RE: mods???
 

Engine simulation software you genious. :eek:
I own a package..... but I don't mod for paying customers and will most likely not do it either unless I get a mill, an engine dyno and a lot of engines to play around with.

RE: mods???
 

so your saying that a backyward guy can extra more out of a top of line engine, that has had already thousands of hours worth of factory R&D and also trackside testing with Novarossi Team drivers, yet you can pay someone $65 and within a few hours they can make it go faster. Think about it, too good to be true.[&o]

Or put it this way, if its just a bit of sleeve work and some crankwork to make them faster, why not just mod a OS RG? theoretically shouldnt it go just as fast as a vspec? you cant can you? there is more to an engine than what the crank and the sleeve looks like.

take a look at the vspec is best example, one the best engines going around and has pretty much a plain crank and sleeve. but its nearly a perfect off-road engine in every aspect (powerband, fuel economy and value for money)

RE: mods???
 

I can't see any where in my post where i said that for $65 a backyard modder could get more out of a top shelf engine. but in saying that you don't believe that any one could grab a massed produced v-spec and get it to run a bit better the factory? if it wasn't possible all v-specs would run exactly the same with same tune fuel etc.

the difference between an rg and a v-spec is time and money and r&d. Its the same difference between the current top of the line engine and the ones from 10 years ago.
