Super Charger Worth It Or Not?

i havent done any math on them but seems in theory the supercharger should work but i think in reality the motors displacement is too small to matter and you would have add considerrably more fuel to benefit the extra air to make more power and to maintain engine safety. you may have install an electrical pumped fuel delivery system.

:doh: :no_commen:

I swear I need to just do a write up and have it sticky'd so all you supercharger expert wannabies can understand how a supercharger works why this one won't.

Ok So I picked up a T-maxx for $90, barely broken in. Everything mint cranked ran and idled perfect. I've machined my own aluminum undercarriage make a working KC light rack, independent power supply with blue under glow.

I'm going over to a full aluminum chassis soon and going to add a NOS
kit. These are all things I'm familiar with but I recently stumbled across the fact that you can buy super chargers for them..

I was wondering if any one has any experience with these and are they worth the $150.. I figure i got a $400 truck for 90. leave me some money to put into it.

If you bought the nice tmaxx for just $90 and plan to upgrade to all aluminum, the costs will definitely add up, pretty soon you will realize you just acquired a money pit r/c truck. Think twice about buying aluminum parts, as they still do break especially for people who jump 1 or 2 story high. When they do break, threads becomes loose, then you will have to replace them and the costs will just add even more. But if money is not an object, installing those nice bling bling to the tmaxx will definitely catch anyone's attention. Also if you have a very fast truck, I would imagine it will surely be difficult to control, unless it will only go straight. Should you decide to go on with the project, I would appreciate to see a video of it. In my opinion, if I had the money to spend, I will convert a tmaxx to a gas engine. that way I don't have to buy the expensive nitro fuel. I will just siphon unleaded fuel from our vehicle from time to time if i want to play with my r/c hehehe.
Good luck.
 
Bulkheads, chassis braces and some like to run shock towers and carriers. That's the only places you want aluminum on a Maxx. Rpm covers the rest. If you want your Maxx to rip, tune the engine properly. If you want over the top power, install a red dot. If you want a shelf queen or a pile of expensive junk, you outfit a Maxx in all aluminum and add a supercharger and nos.
 
+10 on what matt said those rpms are awesome n they don't break often I've yet to break one even when it hit a chunk of reber I didn't see in the grass out in the park all it did was bend a shock shaft and bust the bulkhead (AGAIN 5th one on that side now stockers suck) but the rpm holds up awesome and just flexes then comes right back

And rak reread my post ull see I wrote in full details how a sc won't work ur exhaust port is higher than ur intake port =no boost cuz the one side of the engines still open to let out anything over atmospheric pressure all it does is increase load on the engine cuz now it has to spin one extra part see what I mean?
 
Wow some of you people are just plain rude.

Just for the people that are trying to sound educated on the mechanics
of the combustion engine. Quit you're making yourself sound stupid. I'm an
ASE certified mechanic. And those things that open and close as some one stated are called valves which yes a nitro engine does not have. The piston its' self acts as a valve. And on the TRX 2.5r engine the exhaust port actually sits lower as it's a longer stroke engine.

I was looking for facts as to why it's no good, not just some one to say it's a novelty.

Here's the run down. Stock TRX 2.5r nitro engine. Half a gallon has been ran through it. Tuned perfect, engine stays around 200-215 steady.

Bought the SC. Bolted it in. After Lots or resetting my needles Viola.
There is a minor performance gain in acceleration but not $150 bucks worth.
good thing I only paid $40 for it. But oh wait. I'm just wasting money right>

Ups.. yes there was a slight performance gain..
downs. Pain in the ass to re tune to it.
As mentioned by some one else, yes huge engine temp increase,
by the time all was said and done to keep it running right and the engine cool
the amount of fuel air needed was ridiculous. Was going through full tanks
in about 2 minutes..

So off it came. In went a new piston and sleeve and i returned it for my
$$ back..

For all those pissing and moaning about wasting money.
In the name of research $$ spent is knowledge gained.

Truck has been re sleeved and fitted with NOS. Massive performance gain.
Minimal tuning, fuel consumption, no noticeable difference from stock. Engine temp 2-4 degrees over stock...

Why the Super Charger is no good?
( Massive amount of retuning needed )
( Engine temp increase into dangerous levels )
( Major fuel consumption- Most of which isnt burned )

Will try to add the pics and video on it later
 
The point we were trying to make was to save you that 40 bucks and the pain in the ass installing it finding out it was a pos and having to pull it back off and rebuild the engine. Yeah some of us make jokes but it's all in fun no one was taking personal shots at you. Your idea of research $$ spent is knowledge gained is stupid. If you had really done some research you would have found out that it doesn't work before you even tried it. Most of the people on here have been in this hobby longer than some of us have been alive so it's not like they don't know what they are talking about.
 
A 2.5, perfectly tuned, running 200-215? That's a first. Unless it's real cold out or you have one of those big aftermarket heads on it, that statement is unbelievable.
 
And the reason that people are fired up on this subject is because the research has been done. Years ago. There's no need for anymore debate. The point of this forum is to stop people from wasting money. That way a father or mother of 4, whom has very little money for the hobby in the first place, doesn't read some false information about these superchargers or nos systems. And end up with a bad engine, which they can't replace because they wasted money on the super charger. I'm not saying your info on the super charger was false. It's just been covered. Over and over. There is no substitute for a quality engine and a quality tune. Period.
 
I agree 100% the whole let's try it and see what happens despite of what I've read or have been told approach to this hobby just gets expensive. I prefer function over form I would much rather something work well then just look cool. I thought the supercharger thing looked cool but after DOING SOME RESEARCH i.e. reading this forum and checking out some youtube vids. I found out it's just that. Something that looks cool but doesn't really work. So I didn't bother with it and guess what I save not only the money it would cost but the time and headache it would've caused if I had just tried it to see what happens.

Agreed. Theres a big difference between giving advice, defending advice, sarcasm and then personal attacks. Tone it down guys, I know this is an argument that wont ever really be won but it is something that can be discussed like/by adults.
 
Also cold so ya kno, I'm by no means an expert. I've been in nitro all of 4 months and, if u look, I'm not pouring info out sayin it's absolute fact. I mentioned multiple times in my posts (except my last one), that I may be wrong about the exhaust ports, could one of the actual experts correct me if I'm wrong. And yes I know they're valves I stated that. I'm not tryin to tell you your job and things you know already, but how do I know wtf you do. This forum has everything from 14 year olds to guy who own more cars than years I've been alive. You wanted facts, and those are facts I found thru my research and, as most people here stated a sc is useless and that's all they said because they don't wanna run the whole explanation they already have 500 times. I'm still new here so I'm tryin to contribute as much as I can to other people from what I've found, not be a know it all. So I posted what I thought were the facts of why it didn't work how you interperet that is on you. So sorry if I came off as a know it all, but I was truly just tryin to answer your question in the manner you asked it. Either way glad you got an answer and are no worse for wear for it even if ur pockets are a lil lighter.
 
When it comes to superchargers/turbochargers I am as close to an expert as you can get. I spent 10 years working everyday on them for everything from OEM Fords, Chryslers,Toyotas etc.. to every type of motorsport including road racers,drag racers,tractor pullers and even a 2 stroke Mercury outboard. From every diesel maker to staionary powerplant engines. I even did one for a Russian mine sweeper once.

Any performance increase you think you got was NOT from this supercharger. The simple facts are 1.The design and tolerances in the compressor housing simply will not permit the ability to build boost and 2.The supplied pulley system will not spool it fast enough to build boost if the design were good.

have you ever done anything with the stationary diesel fire pumps ? I have to install them on occasion in new construction. Sometimes they tie into my fire sprinkler systems and sometimes just the standpipes. There's actually quite a bit of work to setting it all up to make it an active system

Not that I know of. I've been out of that field of work for 15yrs now.

Well I ment no disrespect by anything i might have said. I'm an applied science kind of guy. I was looking for some one that had possibly done actual research and took notes. Temp increases, horse gains, fuel consumption ect. Not just some one to say it's a novelty.

I'm not new to the game myself. Just land based RC. I've got a large collection of 3d Heli's.. I even have a mini 4 axes CNC machine so I can mill my own aluminum rotor heads when they go weak from to much inverted flight. And to say $$ spent is knowledge gained in the name of research is a stupid theory is just absent mindedness,. If that were the case cancer studies leukemia ect would make no grounds for a cure. As such in the mechanical field, we'd still be running on steam engines..if that.

Again I apologize if i ruffled any feathers. Just expected a little more from dedicated hobbyists than ( Novelty & PoS )

Golden Horizons Over Stock head.
Stands almost and inch higher than the stock and has larger radius
fins.
 
So I still wanna know did ya get some vids before and after be cool to c how it runs with nos and s-charger as opposed to stock performance gain or not at I think so lol
