i was looking at my throttle body the other day and was thinking that maybe if i take off the throttle valvls (the little flaps that raise up when you push the throttle ) that it will give me more hp or air flow or more overall power

 

That would screw up the TPI system. Those raise as you know when the accelerator is depressed. Your air/fuel ratio will be screwed.

What the hell is this? I have never seen these before. Can you explain further? Does the BBKs have them to?

 

Uh... wouldn't your car be basically running full throttle without the proper amount of fuel if it's open? Sensors would sense it's down and supply the fuel accordingly. But there is no throttle plate, it'll be running very lean wouldn't it? Correct me if I'm wrong.

Oh so your just talking about the Throttle Blades. No you cant remove them. That is what controlls the speed of your car. YOu would never be able to stop if you remoived those, or you car would just burn itself up from being way toooooooooooo lean.

 

hahahh that would suck

 

Wow.

What about making a monoblade throttlebody. Would that work?

Thanks

Hey Cletus just take da gawl darn trottle body off of it! Eberybody knows yous gots to put TBI on it ta make it move!

 

Even TBI has Throttle blades j/k

 

New homemade mod:


My business partner Jack92Formula will be along this evening to describe the process and its uses.

 

Street&performance sales a mono blade throttlebody. It flows 1000 cfm, it looks like they took a stock tb and bored it out to an oval.

I know Jack personally and they put out a fabulous product. Could really feel a difference once their throttle blades were installed on my 91. What is great about this mod is that you do not have to buy one like I did, you can do this in your own garage with simple hand tools.

 

That would be cool to remove the throttle blades, just think of the air restriction you will get rid of. Hey 85 fbod, why dont you just take off one of the throttle blades and take it for a drive. Then tell us how great it ran. Man I heard of moron before but????

 

hey **** you *** hole

 

Venturii throttle blade? Perhaps you could describe it a bit? Are those holes in them? If so, I wouldn't put that on a blown engine. Wouldn't that just keep feeding the engine boost, even in idle?

 

lol 87zya

Blockhead,
I still have not seen Jack92Formula's details on this modification.
Are these just holes drilled into the throttle body plates or are these replacement plates?

 

you get a template and drill bits. the size and number of holes depends on your intended application.

LMAO here. sorry but i found that pretty hilarious. obviously you are uneducated on basic fuel injection and/or basic fuel delivery. just alittle friendly suggestion, if i were you i would search the net alittle or get a good book (such as TPIS's book).

yeah, i would still like to see the reasoning and process behind the venturri throttle plates. i'm not seeing how at WOT how strategically placed holes in the TP would have any benefit. i sure hope im not walking into a trap here

 

Ede,
Thanks for the reply.
Did you notice a difference in idle quality? Don't these holes allow additional intake air that is not controlled by the IAC motor?

 

Tough crowd. You guys can get mean.

 

Edited because I use foul language.

No need to swear 85. While people may forget that we all had to learn somewhere one time or another. And what we might think is a reasonable question others may think is silly, we have to remember that this is a public forum.

I agree with the saying that the only stupid question is the one that is never asked. What no one explained is that the blades on a TB is NOT as important as carb. The TPS has a lot more to do with controlling the ecm (it is kind of like throttle by wire).

The blades are more to help control the vacuum on a MPFI. If you removed the blades, your engine would not go necessarily go WOT...as it still would require the TPS. But you would loose vacuum which could cause some "interesting" problems with MPFI. I can only guess how the ecm would interpet the lack of vacuum on the VE tables.

But please keep it clean. Ok?

 

PS: If I had to guess, lack of vacuum on the VE tables would probably make the engine "run away"; if it wasn't under load.

 

Well said Glenn!
We ALL had to learn from nothing, since NONE of us was born with this knowledge.
85F-body, Sometimes we are all too anxious to jump the band wagon and kid/joke about someone asking a question but sometime someone post a thread about what was the most stupid thing you ever did while working on your car. And let me tell you we've all done something stupid like touching the coil/spark plug wires and getting shocked and you can't let go to fast and your hand bangs into the HOT headers a few times. Or the guy who finding TDC by manually cranking the engine with a long ratchet on the crackshaft pully then when he was done he forgot about the ratchet and started up the car with it on. Or replacing the T-stat and forgeting to tighten the clamps on the hoses and start it up and when the T-stat opens up and lets the water thru the hose pops off not to mention your in front of the car having HOT water spraying at you and your doing the chinses water drill to get in the car and turn it off.
All in all we're not perfect, atleast not this dumb Pollock!
Keep reading and keep posting cause we're all still learning.

 

Your car will not idle with the throttle blades removed. It will stall out for sure. At idle, the throttle blades are shut, and the idle air control valve (IAC) controls the idle speed, by metering air through a bypass, that goes around the throttle blades. If you took off the throttle blades, it would die out instantly . If you took out the throttle blades, and had the TPS set for wide open throttle(WOT) , it would run full nuts until it broke something

 

sorry if it sounded if i was being mean. i thought i was just giving out alittle friendly advice. of course, after rereading my post, i could see how it could be misunderstood.

 

On the issue of the "speed holes" drillled into the blade, it would screw up the vacuum of the engine. I am curious on how the VE tables would interpret this loss of vacuum, but I am unwilling to experiment on my car.

Probably the same effect as a vacuum leak...erratic idle, lean condition, etc.

 

Part of the fun of public boards is that you can talk s%$t. Check out our website for street racers http://www.texasracingscene.com/

All we do is talk **** and everyone knows each other, its hilarious. Yea you might look stupid on a web board, but who cares if someone makes fun of you? Its not like 8th grade when you had a hard on and the teacher asked you to stand up is it? Thats humiliation. Have fun real life is to serious.

 

Actually, I find real life to be less serious. People can see by the glint in my eye whether I am at WOT on the BS or whether I am being serious(rare). Not to mention that using grammar/syntax, vocal inflection, twang and drawl all give clues to my demeanor.

Posting here means [trying] to communicate with people I have never met. This runs the risk of a newbie taking my opinion for gospel(scary) or an old-timer rebuffing/rebuking me for overlooking some apparently(I thought) insignificant detail. Tough crowd indeed, but it keeps ya honest

Glenn,

Good point on the stupid questions issue. "Stupid" questions prevent stupid mistakes. And the stupid mistakes are the ones that cost ya(hard won personal experience).

 

Um, I may be going out on a limb here but the main fuel table is indexed by RPM and manifold pressure. TPS is used for enrichment mode and pump shot. It'll rev to the moon if you remove the throttle blades... I'm not about to try on my car to find out though

 

i am in 8th grade and have a hard on though
