How much difference does the TB Bypass actually make? It seems trivial at best.

 

I agree.. no point in it IMO..

But I feel that way about 99% of all the free mods.

I dont see them "giving" you any extra.. Perhaps, some, like this one, would help you "keep" more of your hp for a longer period of time.

I wont do them.

I would rather beat ya and tell ya I am bone stock than to have to go into a detailed list of crap I had done.

 

Some of the free mods make good sense (EGR mod) but i agree, most are pretty useless on the scale of things.

 

No noticeable difference. I'ts more for the mind than anything else.

Sure, there are those dyno numbers floating around, but I do not believe they are accurate.

In addition to the EGR mode, hacking the airbox on LT1's and shaving the baffles inside the LS1 lid are things that could maybe give you some advantage, but that's probably it.

bah, heat is goign to get from the block/heads to the throttle body anyway..
unless you race out of your driveway


how long is the air in the TB anyway- how much could it POSSIBLY heat up

 

True, but WHY NOT? $3 and 5 minutes time, and it can only help. No one sees it, so it isn't an appearance factor. You don't have to tell anyone about it. It is just for piece of mind. Unless it is winter and humid, why do you need hot coolant running through your TB? When it does get cold, reverse it. You don't even have to take anything off to do it.

Just my .02

 

i dont think its there to "melt" the TB
i HIGHLY doubt it could EVER freeze with the mount of heat under the hood and heat being transfered in thre. and bedies.. a simple tap of the gas would crack all the mini ice crystals anyway.

if its going to freeze, its going to freeze while its sitting, not being driven...

I think its there to prevent warpage of the TB plates/housing

 

I'm not worried about the TB freezing, that is why I did it. I was just making a point that if they are worried about it, that it is easy to reverse.

Now, I understand that the coolant isn't going to "MELT" the TB. However, do you need the hot coolant running through it? If not, then get rid of it. Especially in warm weather, it does nothing good for you. The bypass is cheap and easy to do, and it can't "hurt" you, so why not. I'm not claiming any HP or noticble power, but it can't hurt you. With that said, I wouldn't go spend the $15 plus shipping for the kit that BMR sells because you can go to the zone and make your own for close to nothing.

Again, just my .02.

 

for under 5 bucks why wouldnt u wanna do it.....even if it adds .1 hp its still worth it

 

I dont get it. Even if it is only $5 or less, why would you want to spend money or do something to your car that does nothing. Its well known that the TB bypass does diddly squat. So why would I want to take the time and do it, if there is no end result? Unless you just like fiddling around with stuff, for the sake of fiddling around with stuff, there is no point. Unless your just really petty and want to add it to your list of mods.

 

because it does do something........

 

Please enlighten me, what does it do. Besides route coolant away from the TB. What performance gain can be seen by performing this "mod"?

 

i have been told that if u go to ws6.com

or some site it is actually people that do mods on their cars and the lt1 gained 7hp from throttle body bypass

 

simple, air passes through the TB, the hotter the TB is, the more heat gets transfered to that air inthe same span of time. Hotter air is less dense and also more prone to detonation. less dense air means less power, detonation also means less power. The TB will get warm no mater what, this is true, but it wont get as warm without the hot coolant going through it.

lots of people will say that this mod hasnt shown anything on the dyno or at the track. True, I havent seen any conclusive proof that it really does anything. but I think its pretty universaly agreed that the effect will be very small, even below the dyno's accuracy factor. so any bennefit will be masked by the variation from one dyno run to the next. same more or less applies to the track.

so at this point there really isnt any way to prove one way or the other if this mod truly does anything.

 

My understanding is that air has to be standing still or moving slow for it to absorb the characteristics of its surroundings. Air traveling though the TB moves at a rather quick pace, and the TB itself is only 5" long max. I just don't see the air changing temp that fast.
