Team:

I am planning on doing a throttle bypass mod on my 2002 WS6.
I have heard it has drawbacks in cold weather. What are the drawbacks?

I am in Texas and yes ut does get below freezing quite often in winter. Will this be a problem?

Also, is this mod worth the hassle?

Thanks,

It is a very simple mod to do so if you are worried about your TB icing in the winter just put it back for the winter. I don't know if there are any gains or not but every little bit you can do to get colder air into the motor helps. I really would not worry about the icing because I think I read somewhere that it doesn't happen until like 20 degrees below zero or something like that.

I guess -20 would make sense since the the outside air has to counteract the hot engine compartment... But I was interested in thsi too, anyway to do it relatively free? Ive seen that kit, but can you just buy a couple peices?

Take a look at the bottom of your TB there are 2 small hoses I think they are 1/4" or so. The one on the drivers side goes to the coolant tube that runs between your heads. The one on the passengers side goes to the radiator at the cap neck. All you have to do is disconnect both hoses from either side of the throttle body and jumper them together. I used a peice of stainless steel tubing and a couple of hose clamps that I had laying around in the garage. If you know anybody who has upgraded from an LS1 intake to a LS6 intake then they should have some stainless coolant tube laying around that they would probably give you since when you install the LS6 intake you block off the back coolant tubes.

Why do you say, "Dont do it" Cobray?

BensZ28

yeah unless its like 10 degrees outside why not? In a GM magazine they did that a lid and like !FRA and got like 15 or 20rwhp or something like that, if they are telling me to, I will follow *peer pressure*

No but seriously, why not?

I got bored after readin this post so I went out and got a yard of 1/4" copper tube. I also got 2 hose clamps that were too big...opps. Installation takes like 5 minutes, I just disconnected the hosses from the TB, put a 5-6" peice of copper pipe between them and put the hose clamps(with clothe under them because they were a tad too big) and the clamps that are on there already on the outside. I could pull it off trying as hard as I could so I figure it'll holt a low pressure line of coolent. Total cost of this was like 4 buck I think. We'll see if it helps me any next time I goto the track. Does anyone know when you should revert this to normal? I guess Ill do it when temps outside get to <32, but I might not even drive this car in cold weather... Hope this helps you

For a serious comment: I live in Minnesota and my car has seen some very cold temps over the past 3 years that I have had the mod... I have not had a bit of trouble with it. It's the same with the free thermostat mod. Folks are always saying that it hurts you in winter and the heat won't work... <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> BS! 3 years and going strong with that mod too.
Just do it, it's free/ultra cheap and gives you an excuse to spend an hour in the garage with your baby.

LOL, well now its too late! Anyone know how much pressure is in that line? Im worried about how tight it should be, although I cant move itwith my hands so its probably ok

T/A Fan Dan

There is not much pressure at all. Look at where it is clamped to the coolant tubes. Those hose clamps from the factory are all that is required. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Have fun

I dont see much benefit to having the TBB mod. This is how I see it. Your aluminum block running in normal street usage gets much hotter than the coolant. Look where the TB is in position to the block. Why do you want an uncooled TB running in normal street usage? I can see it maybe providing benefit for a 1/4 mile run while the motor is not that warm. But once the block reaches a temperature higher than the coolant then you lose all the benefit of the TBB.

Flame me if Im wrong..I am not pretending to be an expert but I believe that GM put that thing on for a reason. I have not seen any actual proof that it is a "cold weather mod" from GM.

Another bad reason to remove it is if you bring your car in for warranty work they have yet another excuse to violate your warranty agreement if they want to. I think that is reason enough to not do it. But then again some people have different value systems and this may not be a big deal to some people.

Yeah look where it bolts...ok so? Tons of plastic things are near there and they arnt getting hurt. Plus, in timps below say 80f the air rushing past the TB will be the dominate force other than coolent if its there. Feel the MAF once youve fun the car in cold air for a while, its closer to the temp of the air, not the motor. So when the TB coolent line is off it should stay nearer to the temp of air and not be getting warmed up anymore.

My warrentee is out, plus you can just put it back in 2 minutes if you have some left...

BensZ28: It runs the same pressure as the rest of the cooling system. I don't know the exact number sitting here, but it is usually on the radiator cap. Most cars run 12-16 lbs of pressure.

Run the engine as stock, up to operating temp, leave engine running, get out and put your hand on the TB... <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> Ouch! You burn your hand!
Now, with the engine cooled off, do the mod, drive the car to operating temp, leave it run, get out and put your hand on the TB... <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" /> Keep it there all day!

So do you support this mod or think its trash, and how in the world would that affect emmisions?

I doubt you would have any problems with icing uless you are in subzerro temps anyway. Go for it, at stated in the above post the throttle body wont get hot enough for you to burn your hand.

I already took 30 minutes out of my life and bent some copper pipe and sanded it down and made it look real pretty like...I was just asking ratio411, his post looks kind of negitive?
