Project Taurus, Engine ready Options

[Ted95]

I'm really interested in trying to further cool my engine, I was curious about the SARD breather tank and where you have it installed, have an pics? Did you notice a difference?

[Sunny]

Hi,

here some pics for you, i cutted the lower part of the radiator cap on the radiator to allow water/air flow to the tank











the limited space is the competition, i decided to use this location becouse there was space but on the negativ side there are the long hose ways

a breathing system is a good way to get air out of the cooling system especially when you use a 2flow or 3flow radiator, but it does not really effect the cooling,
even it do (must) there was no noticeable difference


the biggest advantage gives you a pipe instead a hose from the radiator to the thermostat, a hose pulls together and can effect the water flow up to 70% under high revolutions
and a fully opened thermostat

that came out pretty good. now i kno the breather tank wouldnt cool the engine that much, if any at all. did you notice anything with the oil radiator you installed? im goin to install a water/meth kit this winter and try and get some cooling panels and such, i guess im just trying to get the most out of my 3s with out tearing into it.

Hi Ted,

i'am sorry but can you explaine me what "out tering into it" means, my enslish in not good enough to understand

the oil radiator works fine with the thermostat i have oil temps from ~80-100°C

here we go, create as much pressure as possible in front of the radiator package and as less as possible in the engine bay to get the maximum air flow

a channel raise the pressure in front of it and a under panel with openings and tear off edges that look in the air flow under the car lowers the pressure in the engine bay, do you
ever had a look to the bonnet air escape.....you will note that the tear off edge in front of it is not so high as the backside, this is not a ideal design becouse air will escape just in the
front 1/3, air enters in the other 2/3, also the car angle of inclination effect this

i build this to solve it

i'am sorry imagehack doesn't work for now

^ He means that he doesn't want to take apart the motor too much.

[Ted95]

wow thats a great thread, im very impressed i must say.

and ya i dont want to take the motor apart and get bigger internals, im trying to get the most out of my celi with just bolt ons and such. im going to try and get better air flow now even with my front mount intercooler, going to have to try and make sure i get as much air to it as possible. thanks for the info!

[Sunny]

Hi,

i understand, thanks

you do the same like a friend of mine, he optimize his 3S-GTE wherever it goes

here a quick list of what i remember

- JDM ECU -> 100octane mapping
- TTE top mounted intercooler
- water injection
- 3" downpipe
- 100CPI cat
- aluminium radiator
- engine oil radiator

and now he plan do work with adjustable cam gears on oem camshafts

[Ted95]

thanks for the info!

whats next for your beast?

[Sunny]

Hi,

you are welcome

the main part for now is to strip down the engine to get the bores measured and now i'am in contact with cp-carillo for a set of rods and pistons
sub work for now is port work on the head and his water ways, and then i'll possible do a modified oem throttle body

should be enough for the winter

Hi,

Ted, there is another thing you can do to improve your cooling system i forget last time

anti freeze has a very low specific heat capacity and dramatically decrease the heat transfer of you cooling liquid,
demineralised water has the higest specific heat capacity of all liquids and no one ever developed a better liquid for cooling

the last years i drive the following ration 1:1,5 + 2% miller extra cool (2% of the water amount)
i noticed faster temp drops in the oil system after hard road driving, and also saw the liquid faster arriving operation temp.

do not drive just with water in front of rust, further tip -> reuse the old cooling liquid if she is ok, every fresh water brings new air in the system

I just read your whole project topic, you've done interesting modifications!
A lot of custom work Keep it up..

[Sunny]

Hi Roy,

thanks, i keep it up for you

íf it is ok for you i will answer your PM in here

i didn't use intercooler fans becouse i found them useless and it just means more complexitiy, a fan is typically needed there where not enough air can flow -> slow speeds and corners
the trick with the water is to use his high specific heat capacity! and the other thing is a pushing fan just has ~70% power of a equal pulling fan * wich means i had to mount the fans
behind the radiator but there is just ~1cm space to the oil coolers, so there is simple not enough space

* the fan direct the air in rotation and some mm later she must through the straight fins of the radiator, the air doesn't want this and create a backpressure -> a drop in efficiency is to follow

for you oil cooler project i can advise you to use a greedy thermostatic adapter, the advantage is that he also uses sensor ports

i bought a ST205 specific HKS SSQV kit, so i had everything i need to mount the BOV -> air box blanking, flange, further installation parts

but it looks like you have a very fine machine shop, your work looks perfect

greetz

[RoyO]

Ok, I knew pulling fans are more efficient then pushing fans but I didn't realise you installed the oil coolers that close to the IC rad.
Space is always the problem haha I always use genuine Toyota red coolant, but I'll try your mixture next time..

I already installed my Blitz sensors alongside the oil filter: http://www.6gc.net/forums/index.php?showto...mp;#entry944309
So I'm going to buy a thermostatic adapter without the sensor ports. But thanks anyway

Hi Roy,

space is the only problem of our cars
the radiators are mounted instead of the A/C condenser





thats is a great sensor mounting position, why doesn't find myself the position too

Hi,

small update, the block is stripped and measured some time ago



i ordered CP pistons in 86,25mm 9:1CR
and carillo h-beam rods

damn nice build sunny! What did you do with the crash bar?

[Sunny]

Hi,

you mean the black bar behind the front bumper? is still in place.....i would never tough a safety item

greetz

are one of those radiators, replacing the A/C condenser?
or do they serve different purposes (oil/trans cooling)

**EDIT- I guess what I am asking is if you got rid of the A/C compressor, or replaced it**

I was looking into getting rid of my A/C condenser and replacing it with a smaller cooler like the ones you have placed in front of the radiator.

hope i have explained everything ok!
thanks

Hi,

i understand what you want to ask

i droped the A/C condenser so i will not usw A/C any more, a compromise that i decided becouse i never often used it, i want a good radiator position and also a good oil line routing in the car where they are more safe from
crashes becouse of this we relocated the lower mountings of the water radiator to get the maximum gap between radiator and chassis

left on the picture is the engine oil radiator and right the smaller gearbox one

let me know if threre is still anything left

greetz

[Tigawoods]

yeah that answered all my questions! thanks!
