I am going to bypass my trottle body this afternoon and I was wondering if there is anything different when doing this mod to V6 instead of the V8?

KED85

IF you are in Rochester NY state, I'd strongly suggest against it.
It's cold enough up there why make it harder on your car?
Gains are not too great, if at all.
Increase cooler OUTSIDE air to engine throttle body inlet and reap the gains that way!

its a freggin useless and timewasting mod....

I wouldn't say it's useless. I makes it easier to work on stuff right there... those two little hoses are little bitches to work around and/or get off. Parts stores don't seem to know what they are or if they have replacements... and don't seem to have the right angles to make them either. *shrug*

Yep, the whole point of doing it is to increase reliability of the cooling lines by eliminating the TB coolant lines all together. Thus making the motor much easier to work on when diasembling the upper intake manifolds and not having to unhook or bend out of the way the TB coolant lines.

I don't know about your car, but on mine it was worth (dyno proven) 8 RWHP

no reason to laugh at her just because you think she is wrong. you were a noob once too.

Hell I more shake my head in sadness at the statement

I don't have a 3rd Gen V6, I have an LT1. How is it so hard to believe that a 30-40 degree drop in air-charge temperature would give me 6-7 RWHP at operating temperature (210 degrees approx).

Obviously you don't know much about cars if you don't see how this is beneficial.

At operating temperature my engine runs at about 210 degrees. Well, that's what the COOLANT is at. And the COOLANT before the bypass, would run straight through my throttle body and make the plenum REALLY hot, hot to where I couldn't even touch it.

After the bypass, the coolant no longer flows through the TB, thus allowing the intake charge to have a much cooler temperature (thereby making it denser and allowing it to burn hotter and more efficiently) and thus making more power.

Refer to THIS LINK for any more "lmao" statements.

Remember, your engine has 2.8 liters of displacement, mine has 5.7. That also has to do with the fact that I picked up HP and TQ.

One more thing, this is the EXACT theory (and fact) behind a Cold Air Intake. See the first word, COLD. That's because cold air makes more power than hot air. Same thing with intercoolers, cold is better than hot.

lmao


Thats 3.1

urbanhunter44

iTrader: (3)

okay, 3.1.

Well, think what you want.

What I will tell you is that yes it does have a dyno proven effect on an LT1. Dunno bout your V6, or even an L98 for that matter. But on an LT1, there is a dyno proven change.

And do you seriously think that 115 degree air will provide the same density and power potential that 70 degree air does? I don't.

That's all you have to realize to know that it lets your motor breathe a little cooler air, thus allowing it to make more power.

EDIT: And again I do not claim that it will make the same improvement on your 3.1L V6. I have no idea.

V8 Slayer

ok ok ,its just unusual someone claiming they it was actully worth doing,performance wise.

KED85

Make this simple.
WHAT MAY WORK AS A HOP UP TRICK FOR A V8, may NOT give same benefits for our V6s.
YET it is quite true that a TB Bypass may work well for the V8 rides due to.....
I still shake my head that some one says Long Live the GOP. From one that helped elect to power two Repubican Presidents of USA (and also helped one Democrat President, too!) and worked for a Republican Senator in US Senate in DC.

Yes it is unusual, and LT1s and LS1s are the only platforms that I've really seen it make a difference.

I have no idea about your V6.

Yes I stated above that I wasn't sure of the benefits on a V6, for obvious reasons.

Your political thoughts are your own, but let me say that I agree with MOST conservative views, and if Kerry was in office, my family would be on the streets. So even if I didn't agree with the GOP, I would still vote for them. But I do agree with them, so LONG LIVE THE GOP. lol.

KED85

Atleast you are concerned enough to hopefully vote.
NO MATTER WHAT PARTY
But to just say....that statement is akin to being a **** lover car buyer! Sad.
IF ya was on the street due to Kerry being in office, your situation was shaky from the start.
No Presidential election should determine your future you control your own future.
And that includes engine modifications.
Incidentially a V8 does injest more air (it's a bigger air pump) than our V6.
Converse is that a ***** four cylinder is a "oversized motorcycle engine" which eats 10,000-12,000 RPMS for breakfast. Because it spins faster, that compensates for air needs.
Our V6s live in low RPM land, undersized and using "only so much air (demands)" for making power
By making outside air entry to V6 engine, cooler, that is more effective IT SEEMS than the TB bypass on our V6 rides.
But use this trick on a V8, yes it seems, due to air(pump) needs, the help is seen in the V8 TB Bypass example. Yeah it can add the slight V8 HP gain.
Long Live Capitalism!

I wouldn't say it's useless, and I wouldn't go expecting 8 HP out of it. It's more of a street mod than a dragstrip or dyno mod anyway; I bypassed mine 8 years ago just for kicks.

Aren't the LT1's reverse cooled, anyway?

And I'm not sure what relevance any of this has to V6's from 85-92! Well, other than, if you have a scrap of 1/2 inch heater hose and two clamps lying around, might as well bypass the TB coolant lines. It helps clean up the garage of extra heater hose.

Yeah they are reverse cooled, but all that means is that coolant flows to the heads and then to the block, nothing really to do with the TB area.

This is a dyno graph of a '96 LT1 doing the throttle body bypass, I've copied below what he posted along with this, it does do something for a V8 at operating temperature but I don't think it would have a huge effect on a V6:



Here, the dyno shows a 6.3 horsepower and 7.1 ft/lbs torque difference between having coolant run through the throttle body and bypassing it, with an average gain of 5.6 horsepower and 6.8 ft/lbs torque.

I made the first test after driving the car for approximately 15 minutes. I monitored Coolant Temp and Intake Air Temp while making the run. At the beginning of the baseline run, the coolant was at 178F, intake air was at 80F, and the throttle body itself had a surface temperature of 102F. After bypassing, I again brought the car to temperature and repeated the test. This time, the coolant was at 180F, intake air was 80F and the throttle body was at 82F.

To make sure the runs were accurate, I set the cruise on the dyno to 70mph in 6th and let the car run for about 6 minutes. After this time, the throttle body had reached 100F. I let the car cool to 185F coolant temp, and 88F intake air temp.

Running the car again with these elevated heat readings yielded another .2 horsepower and -.2 ft/lbs torque compared to before heat soaking the engine. Check out the Dynojet Race Routine between the stock vehicle, the stock throttle body coolant routing and bypassing the throttle body coolant.

And KED85, my family is entirely self-employeed. We own a small business auto shop in California. If you know about politics, which I'm sure you do, you can see how Kerry being in office would hurt us very very bad. That would leave my parents and my two little sisters, too little to live on their own, stranded. I live by myself, so it really wouldn't hurt me... besides loosing access to a lift lol.

I agree that Bush was not my best choice, and I actually would have preferred John McCain. But to use a phrase, Bush was the lesser of two evils.

But lets drop this, if you want to continue feel free to PM me or e-mail me.

KED85

Drat you're up north
LUCKY
I need a shop down South of ya for some help.
Bush is the lesser & it was hard to even vote this time.
BOTH lousy choices.
Atleast ya voted to back up any choice ya made. That's a major plus among most 3rd Gen members.

RSFreak

My reason for doing the bypass is mainly 'cause it makes removing the upper intake plennum much easier. Removing the EGR tubing helps too.

Stealthy-One

I think RSFreak hit it on the head.

BTW, if you do a search, I actually used data logging to compare the Intake air temperatures both before and after the TB coolant bypass.

MUCH lower with the bypass. Of course colder air requires more fuel which produces more power, therefore there was a power gain to be made. Granted this was on my Z28, but same principle applies. I'm too lazy to search, but if anyone feels like it, the data is there.

gottfuel

can some one please telll me whay this is in the v6 forum? why is she not hanging out in the alternative forums!! also just because dude laughed does not mean anyrhing ! hell for all u know maby he thought what you wrote was cute!!.,.,
