t-maxx 3.3 with fuel injection

[SuperCrazyForce]

Nice sound :D

[SuperHydroracing]

It's cool,my jato is geared all top end,it's unreal fast.Lean it and gear that sucker.Low end is fun but it gets old.Oh the jato 65+ out the box lol yeah right.40+ is more like it.It took so many different ratios of gearing to get it to go 65+,it will now.I think it should be considered false advertizment personaly how companys print that BS on items.I had a T-maxx yrs ago with a 2.5,i do miss it,the 4wd.My jato is almost usless in any kind of slick terain.

[fireman62truck]

you got a quick 1st gear to 2nd gear ratio? sounds good for stock piping i went with ths racing piping on 2.5 tmaxx swapped to 3.3 motor

[NITROrcKing007]

looks like a waste of time

[peepers56874346]

Just as a one off would it be possible to make a mini alternator fo a nitro rc car to charge the batteries?I understand it would take power and lower fuel mileage but would it work in the first place?

[traxxasrc1]

u need to tighten up ur spur gear just a little

[electrified302]

@traxxasrc1 is that what u thought i the idle screw was out to far making it to rich down low in the rpm loading the engine

[princenick00]

Fuel Ingectors suck on nitro R/C cars because you are running them way rich!!!!!!! Think Man Think .

[electrified302]

@princenick00 i dont know if fuel injectors suck or not but i did think the motor was to rich off idle

[mstreamer9991]

It's not fuel injection mr. rocket science. Sounds like shit, looks all cobbed together.

[SpecializedRider270]

Totally With you tmaxx94

[dunlapcars]

add a supercharger and that fuel injector and that thing would be a beast

There is a supercharger from RB inovations. If you put the two together it will force air and fuel in the carb causing a bigger explosion which causes a major increase in power

[quadracer111]

Your obviously a tool. Those superchargers do not do anything besides make your engine run leaner. And they cannot work on our little 2 strokes because the intake and exhaust port are opened at the same time thus any forced air into the intake simply just go into then out of the exhaust.

[electrified302]

@quadracer111 cant u add more fuel, richen the mixer i know some of these carbs have a lot of play on them. ive seen blowers on nitro 2 strokes before and man those car were so f!@#un fast unbeivable. who knows how they made it work.

[quadracer111]

It has been proved these "superchargers" do not work, the intake port is open the same time the exhaust port is opened therefore any forced air is a waste.

[space387]

@quadracer111 Its fuel injection not forced induction.

also @fatkidjoey what did you use for the injector? I'm looking at a similar idea

[davidsrx793]

Supercharger dont work on 2 stroke becuz the intake port and a exhust ports are open at the same time so forced air gets push out with the exhust cuzing the engine to go lean and shorten life.

[electrified302]

@dunlapcars ooooow i want that

[tmaxx94]

i really see no difference in performance

[StevecZ28]

r/c cars are not injected...even though you have a line coming from the exhaust to the fuel tank still doesnt mean its fuel injected.. its only taking the xhaust pressure to pressurize the tank. thus meaning its a fuel pump. not fuel injection...

[mrgrouchyguy]

Unless you have a onboard comp. A fuel injector, & a whack of sensors on it, it's not injected. Hust like super chargers it's a crock of SHIT. Stick with a good pipe or nos which leans out your fuel/ air mixture to give you a quick blast of HP.

[aidanhd]

nitro rc cars r sort of fuel injected anyway; they use th exhaust pressure 2 squirt th fuel ino the engine. thats y thers a pipe from th exhaust tailpipe/silencer 2 th tank. 2 me, it looks lyk u justadded a load of weight on2 ur truk wiv all that electronic fuel injection shit. lookin at th performance, it looks lyk my stock mt2 wud giv ur 'fuel injected' t-maxx a run 4 its money. if i was u i wud rip that shit off and install a nitrous injection kit

[ZombieWeinerDogs]

RC cars or trucks are not fuel injected

[aidanhd]

they r in a way bcuz th exhaust is used 2 force th fuel out of th tank nd into th carb. if u look inside th carb wile ur priming th engine, u can c tht th fuel is sprayed in thru a little nozzle. it a bit like fuel injection but not electronic

[AEbuggy]

How does it work?

[therealtrenasty]

thats a contraption if i ever seen one..why dont you just get a tuned pipe whats the diffrence hear his is the biggest peice of shit idea did you zip tie that batt on the back there...yea learn to tune and to drive

[390851]

it sounds like its getting a little too much fuel.........thats just my opinion, if im wrong, someone tell me........

[jimgotnitro]

it sounds a little lean at top end deosnt it??

[deathcrayon]

Agreed.

[owning666]

man its definetly noty an improvement what so ever.,.. i have a tmaxx and its runs way better stock.. the stock one wheelies on command no problem

[vegaimpala]

Yours is most likeley a 3.3 not a 2.5 like this one and shure as hell not a .15 like mine

[mofoyie]

the lo-end sounds a little rich

[AliveoutofSpite]

This is probably the biggest crock of shit I've ever seen, right up there with those superchargers.

Learn to tune, learn to drive. My T will stomp the shit out of this, then take those pieces and stomp the shit out of THOSE pieces.

And the best part is, it's still carburated.

[390851]

well you can do alot of talkin on the internet, why dont you put your money where your mouth is, and prove it?

[tmaxx94]

i agree with you dude this doesnt seem to do anything except make it sound like crap

[CRF150EXPERT]

it sounds bad because hes runnin it rich

[tmaxx94]

so its slow and it sounds like crap lol yea this fuel injection is so much better

[CRF150EXPERT]

i hope you were being sarcastic lol

[tmaxx94]

lol i was haha

[Socalguitarist460]

If this truly is an efi system, where did you get the motor (or did you drill the injector bungs yourself), the assortment of sensors, the computer, and batteries.

Also, How much did you pay for all this?

[sickler4201]

WOW! I don't think I've ever heard one run this shitty on the low end! Lean out the low end dude!

[MdNitroRacing]

Dude it's freaken fuel injected it isent going to sound factory fresh

[sickler4201]

Bull shit its fuel injected! He's proboably just got the nitrous bottle injection. If it was fuel injected he would need an electric fuel pump, micro injector (don't think they even make them that small) and a computer system to control the injection. Fuel injection doesnt work very well on a 2 stroke anyway due to the porting and exhaust/intake port overlap.

[MdNitroRacing]

Mabey you're right

[revoftw1]

Dude lean out the low end it wont bog down and die on you then

[savagekillen]

that sound like the old kyosho gs11x engine

[Treddtruck]

what is fuel injection?

[156TYSON]

its basically when fuel is forced into the carbourator and a turbo is when air is forced into the carb.

[Socalguitarist460]

no it has nothing to with a carbourator. EFI stands for Electronic Fuel Injection and it's a pressurized system where the computer mandates how much gas the injectors put into the cylinder cavity.

And again, the turbo has nothing to do with the carb. A turbo forces air into the intake so the engine doesn't have to suck it in, thus allowing more gas to get to the motor.

[MdNitroRacing]

It mean's the fuel is Getting stright fuel instead of it beeing mixed with a carb

[Socalguitarist460]

Again, totally wrong. In any internal combustion engine, you have to have a gas and air mixture, and the carb is just a mechanical means of producing that mixture, and thats why you have to tune it. EFI however is a computer controlled system that allows different amounts of gas into the cylinder cavity depending on how open the throttle is. To get this information, the computer has multiple sensors on things that affect how the fuel burns such as O2, temerature, humidty, and air pressure.

[MdNitroRacing]

True man I agree with ya

[elise308]

lean out the bottom end!!!!

[lamaq101]

what was top speed?

[DumbFoundedFilms]

slow my revo 2.5 was faster

[GEO3535]

does not look fast?

[atvrider814]

cool idea.. needs work.. runnig WAY TOO rich

[GEO3535]

How much did you, or anyone elses T-maxx 3.3 pay for.

[8221367]

750

[GEO3535]

750 sound to much

[snusnu41]

$400 with all the necessary stuff

[GEO3535]

good price

[boogaloog123]

learn how to tune a maxx and drive one

[GEO3535]

I just got a T-maxx 3.3,do you have any helpful tips on what i shuold'nt do.

[marleyZ33]

still slow

[anniehimself]

How and why? Would you mid sending me some pics of your setup?

[cejay30000]

looks slow/

[blown96ranger]

dosent sound tuned but its just a test run at least its not super lean so rich is good when testing not testing and tuning

[yamahamike500]

dosent even sound tuned...........

[joeldude76]

you should get a performance pip it will make it go faster more hp and saves some gas i just got one

[joeldude76]

whats fuel injection?

[Sparrow338]

What do you mean by fuel injection? You just mean that you can force more fuel than normal into the cylinder when you want to? Or that you actually changed the engine from a carburated engine to a fuel injection engine?

[cgbben1]

Ok, you don't get what a two stroke engine is, do you?

A fuel injection would not work because both the exhaust and fuel ports are open at the SAME TIME! therefore any excess pressure or fuel would just be spit out the exhaust port. Have fun wasting fuel, idiot.

[brummieD]

Dont worry just critisizing the tuning a bit but I think its a cool idea =)

[brummieD]

Its pig rich but nice idea :)

[fatkidjoey]

you guys got to undersatand that this is something just in the works

[deanr5]

my savage with a well tuned 4.1 looks faster than that

[fatkidjoey]

ok a 4.1 vs a .20 yea i bet its faster

[Snowshredder4life]

@fatkidjoey the 3.3 is actually a .18...

[TheJackeyboy]

@Snowshredder4life

erm .18 is 3.0cc .21 is 3.5cc so .20 is 3.3-3.35cc

[6650roger]

a 4.1 is like .26 and his is a .20
