DIY: Throttle Body coolant by-pass...

[gszam]

i agree with u mO 64 stang........old school trick from the early 90's mustangs

[asdf]

Will this also make it for harder start ups in cold weather or will it just take longer to warm up?

neither

seriously? I've been reading it takes longer to warm up at least everywhere..

so does this mod eliminate the potential gains and benefits of the p2r throttle body spacer? or should i still get one?

If anything it will increase the gains you see with a spacer.

I think the spacer itself increases air volume, not sure, us R18ers dont have one so I dont care to read up on it. But I know for a fact you need two gaskets ( or it's recommended).

The gaskets help prevent heat transfer. By removing the routed coolant to the TB, you are eliminating a HUGE source of heat. So doing that will help the gaskets to further prevent any more heat transfering from the enigne > TB > intake.

Colder tube = Colder air = denser air = more HP.

If no heat is being used on the throttle body it should, theoretically, make the car warm up faster.

Keep in mind what happens when air is traveling fast and being compressed.......it gets cold....add a little humidity to the air and what do you get.....freezing water and if it freezes to the TB it can potentially freeze it and make it stuck open...if you live in an area that goes below 60 degrees I don't reccomend this...wich reminds me I have to change mine back to stock cause it's getting cold out....

do you have a turbo or supercharger? cause if not your not compressing air in the throttlebody its just getting sucked in. also the intake manifold will be the same temp or maybe a little cooler then the engine and the throttlebody is connected to the intakemanifold making it the same temp or atleast a few degrees colder since its farthest away from the engine making it warm and not gonna freeze. do this if you think it will freeze, warm your car up to normal temp and spray CO2 on the manifold and see how long it stays the white frost color. if it stays frozen for more then a few seconds which i dont think it will then change it back to stock but if not leave it cause your not gonna have to worry bout it freezing the throttlebody.

I rest my case...its not worth having it freeze up on me when I need the car the most...I still don't trust it....sorry not buying it....when it's cold out I will be putting it back to stock....

60 degrees. Wow...well I guess that we are all out of luck then huh...I mean I live in a desert that gets snow...so what is that saying about the rest of the country. Most of your post was well put...but that...it helps to think sometimes. EVERY part of the country gets below 60 at some point.

Curse the drive though in the middle of winter...damn McDee's for making me stop and freeze my TB. BS.

By the way...water freezes at 32. And im not a even meteorologist.

ok smarty pants....the air passing throught the tb can get up to 30 degrees cooler when passing through the tb if given the right conditions....driving on the highway for exstensive time with TB open to 30% or more can cause freezing... the engeniers have put coolent through the TB for a reason who are you to challenge thier time tested and proven technology.....Every car i have seen with a TB has coolent running through it....I have even seen some with thier own thermostat on them to controll coolent flow... it's not there for the hell of it...yeah you may get performance from it be removing it...but not enough that you will feel it....if you want power get bigger displacement or go FI....my $.02

Wrong you have a blockage in the throttle body...it's called the throttle blade..air being sucked in and a blockage from allowing the air to go in causes pressure.... and when pressurized it causes condensation to form.....
plus the mass airflow meter is before the TB so what is the point of cooling air when the Mass airflow meter already told the computer how cold the air coming in is......this set up was good on TB setups without MAF's becuase the IAT was usually bolted to the IM after the TB....and Map sensor was after TB as well.....MAF replaced these 2 sensors.....you want to cool the air before it gets to the MAF hence the reason for CAI's...
Not that this matters...I have a degree in applied science and am a mater tech at a lexus dealer read my credentials in my profile then ask your self why are we even having the conversation.....

Like one of my teachers said, don't trust anyone with a PhD. Im not saying you are one though...

Alright.

+ There is no compression of air when using the stock intake system or any other intake system (SRI, CAI, IceBox).

+ Water does not freeze at around or a bit below 60 degrees, more like 32.

+ The air temp. going through the intake is not 30 degrees below outside temp. It's actually about 30 degrees higher.

+ Reducing the temp of the TB will help prevent heat soak to the intake itself and also traveling air within the intake. Thus increasing HP.

+ This mod is most effective in warmer climates where their is no concern of a freezing TB.

+ I don't honestly see how a TB could "freeze" stuck unless it was drenched in water and flash froze.

+ I don't have a degree.

I agree with this as stated in the orginal post for warmer climates only....

[Agnt004]

When air is compressed it does NOT get colder, it gets warmer just like anything else that is compressed. Air only gets colder when its decompressed, such as a co2 cartridge that gets colder when being used or letting air out of your tire. The coolant is there to keep the throttle body from freezing over in sub 32 degree weather, effectively acting as a heater to the throttle body since the coolant is around 200 degrees or more when warmed up. For this reason it is only to be used in areas that never get below 32 degrees, Florida for instance, since there is no chance it can get frozen. I do not have a degree, but I took multiple physics classes in high school and college.

Wow applied science degree. very impressive...but isn't that a degree for someone who got rejected from an engineering school? Just wondering...

Dude... If you are right. I give you big props on singing up just to burn him.

******* awesome, first post and already getting my rep.

air is not pressurized into the combustion chamber. when the piston goes down and the exhaust valves close is sucks the air into the chamber then the intake valve closes and then the ehaust valve opens and its pushed out.
