I've seen it thrown around quite a bit, and a few people get new ones. Now, to my understanding, and i could be wrong, is that a TB is the part from your accel pedel to your engine, it tell it how much to rev and how much power to give? yeah..? -ish?
Well, some of you may have read that I think my car doesnt give up as much ball as it should, I know the engine has the power, but i just can't seem to get it to the road in alot fo situations. Would changing the throttle body help this?

buying a new throttle body wont do jack, ull have to find a work shop or if u know how ur stuff have a play with it and open it up more,

honestly its probbaly not the "power" mod u were looking for its just a basic breathing mod that will give u more gains the more u mod ..

how ever u could take out the inner lip of the TB which is kinda slightly restrictive but wont really do jack

Hrmm, it's not the power i'm after, it's the response :P

getting a new standard tb again will do nothing to responce or power. You need to at hi flow the tb to make at all a difference.

an after market throttle body will give you:

1) TPS issues
2) no more power
3) no more torque
4) the illusion of responce
5) no extra responce

If anything it just messes up the ECU inputs.

say a 50mm tb flows x amount of air at 25% throttle
you put your foot down 25% with the 55mm tb and it goes faster
hence illusion
now you could have just put your foot down 30% with the old 50mm to get the same amount of air flow as the 55mm tb
hence no extra power/torque
so a tb only effects peak power, not torque, because at low rpm the tb is not restricting due to low intake air speeds
and at high rpm the tb isn't restricting either, because they are already a perfect size for the motor

and it plays with the ecu because the ecu see's more air from less tps and isn't really mapped for that sort of never seen instance.

turbo charade i dont know why you are still on these forums, every answer you give seems like the only way to get power is to turbo a 3 cylinder ,

anyways, as others have said, get your standard tb (which is big enough for pretty much all your basic naturally aspirated mods), and get it high-flowed . Only costs about $100 and will improve your throttle response markedly.

will also flow more air at WOT, but other restrictions on the intake may negate this gain


later :cool:

Im with Benny, does every answer have to be so righteous. Who cares if its only for response, major impressions of a cars performance are based upon throttle response and generally it will be nicer to drive.

Well response is all i need. As i've said, i 'know' there is enough power there, it's just not getting drawn from the engine, my foot is flat to the floor but my car just sluggs along at 2.5k rpm...

That sounds like a different sort of problem but give it a go.

You have a go at me, and then back up 100% what i said :confused:

mate i can't be bothered with your bickering, just pull ya head in or go to a charade forum .

Boys boys, dont make me flick the lights. lol

TC is right in technical detail but ya gotta stop rainin on their parade Jason. :)
If it makes em feel better, let em do it. Maybe hes gunna get a piggy back comp and remap it. :doubt:

Ya know Benny, even if he disagrees with ya, its always good to hear both sides of a story.
It gives the person all he needs to make an informed decision. :)

Ok, everybody, group hug,........................ there, isnt that better. :D

now im not disagreeing with you IN ANY WAY...mainly cause i have NFi what im on about...........but if you placed an object behind the accelerator pedal, and pushed the pedal hard against it, wouldnt this give you a sturdy basis to say "when i get my high flowed TB it should respond faster"

and then when you get the High flowed TB do the same thing and see what difference it gives.....


sort of get what i mean....... :confused:

that just popped into my head, feel free to shove the thought back in :P

personally i take everyones opppinions with a grain of salt!

bout a year and a half ago i posted a question about what would realisticly need to be done to a 3.5L to get 200 kw's atws if was said across the board it was impossible and ur streatching to get 200hp atws .... how times have changed!

lets face it, there is still alot to be learned about magnas ... unlike say an RB20 or a 350 .. where everything has been tried and tested,

i also remember hearing over a year ago it was IMPOSSIBLE to S/C a magna ... well we have s/c kits now,

personally i dont think getting a larger tb will make heaps of difference but i think it would be a worthwile mod that accompanies a range of others

if it wasnt for this forum we would all still think ralliarts r "da ****" ... still think 140 atws is an exceptionally quick NA magna, and wouldnt know 100's of other things that we have found out through experimenting and posting/discussing on the forum ...

i think give it 6 months and we will know what the story is with the TB's as quite a few ppl have plans to make/buy/sell some bigger ones

Look at it this way.

Its said that $100 per 1kw is a reasonable figure. If you get your TB bored out and you gain 1kw in power and a bit more responce and it costs you $90. If you pay your $90 and all you get is placebo effect. its only $90.

Its Reasonable.
