3t-gz??

[merc-blue]

G'day guys
Im looking still looking at building up a engine and was wondering if anyone has ever gone for a supercharger on a T series engine? i would really like to keep it on carbies.
Any info on the subject would be nice.
other option is to get cam timing gears to give it the whine instead lol (joke)
Thnx

There are two threads you may be interested in, but youll have to search for your own answers
- Search yahoo or google for supercharged 2t in a celica i think its on a toyota web ring or daytone site but ive posted the link in the tech and conversions forum no too long ago
- Search forums for "gilmer drive" covered recently, its a discussion on 3t-gte gilmer drive setups as they would have to be custom as noone makes them as of yet

Anyways all the best - LeeRoy

as said before, forced induction + carby, in this day and age, is pretty crap.
get injection manifold, get SC, make up brackets and pulleys, get it tuned.
simple

carbies and forced induction, while still not bad when done right (= much messing around with tuning them), will still not be as good or as safe or as fuel efficient as an EFI system..

either stick with NA carby for the fully sick sound, or EFI with quads for fully sik sound, or EFI and forced induction, done properly..

have fun

thats what ur lookin for mate
P.S still buy my carbies

i would'nt say that top fuelers(not to count 3/4 of the drag racers) have great suscess with chargers and carbies

a fair few fiat boys run chargers with a 48 dcoe/dhla hanging off the side with massive results plus the added benefit of being able to tune it finely with a flat head driver and the low cost of it plus the afftect of runing a carbie threw the charge is fantasic fuel cools the fins and fins compress fuel

it'll be runing a suck threw set up right?

as you can probaly tell i love my carbies=teh win

edit:like chocolate for the eyes

hmm thnx for the info i might look into it abit more but for now a NA 3T-G.
maybe a 4AGZE FTW

i have a dislike for turbos, its not that they dont add great power its mroe the "fully sick" commo driving mechanic apprentices walking around and making BOV sounds, has put my off a turbo. unless it was gonna be somthing very mean (and i dont have the $$ to build a mean forced induction)

good points, but you know if topfuelers and other classes of drag racing could run electronic fuel injection they would..
as it is, top fuel run mechanical fuel injection don't they?
from how stuff works

All fuel isn’t added at the same place. Among other things, to get a possibility to control the temperature in the blower and intake manifold about 20% of the fuel is fed in the injector and 20% into the intake. The rest of the fuel is shot down the intake channel just above the intake valve.

i'm pretty sure top fuel is mech injection.

top alcohol etc, i think still run carbs.. simple because they are restricted by the rules.

that said, a drag car is prety easy to set up because it has a very small operating range. it doesn't really ned partial throttle, it definitely doesn't need economy. it jus runs flat out.. usually

as for suck thru, it does cool the charge a but from fuel evaporation, however, that means that you have hot air and fuel in manifold. it can go bang. backfire with suckthru is not pretty, although you will kill the charger first. blow thru, i suppose you will blow out the carby first

there is nothing to say it cannot be done, however, it is eleventy billion times better to run it as EFI. and it will be easier to pass engineering too

i like carbs too.... but if you like them, you could run a TBI throttle body with a megasquirt electronically adjustable carby

sorry oldrolla i got my pro stockies and top fuelers mix up

yes from what i've seen top fuelers do run mech injection i find it quite strange but it does do it's job nicely

for sure if your looking at making a bit of power run efi it's good in all accounts far far superior when it comes to forced induction but it's the price of all the bits and peaces that adds up plus the fact that you need a university degree to even comprehend on how to tune the blasted of a thing fuel maps and all kinds of things gos on there i dont know i think i am just oldskool at heart

but yeh for some one looking for a little more power and looking for the boosted affect with limited pockets and trying to keep it oldish i say carbie the thing as your pretty much said close results can be had with the right set up and tune running carbies but there are a few side affects when doing so as oldrolla said back firing is not pretty also i found that you get a strong smell of fuel that can be a bad thing

but ever one knows when to comes to sounds you carnt beat a angery high comp carbie mechine pure extacy

I have spent all day today reading whatever i can on TBI,
and im really keen to setup a NA TBI 3T-G.
i hvae a few questions
firstly i think a dual 40mm throttle body (fit on a existing manifold) would be sweet, agree?
next question is length 30, 93 or 118mm if i wasnt going to run trumpets but a airfilter in this style LINK
I have NFI on what would be best but the 118 appeals as i read that a longer body is good (but may have misunderstood)
megasquit computers look arite and price is right in kit form but how hard to write a map/profile specifically for TBI as opposed to regular injection. are the dyno guys gonna look at it and go WTF we cant touch that or be sweet with it?
info would be good
Cheers
