3S-GTE people, Wondering..... Options

[spunky393]

I just noticed, and don't ask me why i just now noticed this, but wouldn't the top mount intercooler be better over all. Especially for drag. If you don't follow, you'll notice that there is only half a foot from the turbo to the intercooler, and another half a foot from the intercooler to the intake manifold. That means LOTS less turbo lag. So, wouldn't your gains (at normal psi) be the same from putting all the piping and weight into the front mount intercooler be the same as leaving your top mount, with the at max, foot of piping??????

the problem is that most people have an ST185 engine in their car. the stock air to air intercooler just ends up heatsoaking, because our cars dont have any type of a hood scoop to draw the air in..


the stock st205 intercooler would work great tho.

Drag or lag?

I've talked to ST185 owners who have upgraded to FMIC, they say the lag is minimal and overall the car performs better.

I wasn't asking if it was true or not, i was asking which one is basically better. What is this chargecooler, and is there anyway to enhance the topmount to work better. (every bit of time counts, that's why i ask these questions)

[shid]

Well, you had an inaccuracy in your post. You stated that top mount = less lag, and thats not really true.

As far as improving a top mount- if you can get water cooled thats one thing, and then a hood scoop (WRX style or 'vette style is probably best).

But you're very limited sizewise on a TMIC. The easiest way to improve IC performance is by getting a larger one (more surface area)

[spunky393]

haha, i don't know why i'm asking, but more for my database in my mind. Is there a way to create a "larger" top mount, or more lazy, but one? What about that caldina (spelling may be wrong?), what's that got on it?

[Supersprynt]

I believe the Caldina has a W2A but dont quote me on that.
Under the 6th Gen hood theres not enough room for a bigger IC, its a tight fit already. If you want to remain TMIC and the most efficient then W2A is the best.

For whatever reason you want to stay top mount....
you can put a water sprayer on it and it will make a big difference as long as you got a good scoop design pulling air into the ic.
it is like sticking you hand out the window of a car driving down the road....then sticking you hand out the window again when it is dripping wet
the wet one is fells much colder right!!! = more dense air

i still say to go front mount though cause it is away from major heat? cause when you stop at a light or in traffic the top mount is just getting hot sitting above the engine and takes a while to cool it back down for better performance.

What curves in a hood scoop, mines direclty above my intercooler.

Thread hi-jack. To the 3s'ers. Last night i was driving, i have my boost set at 12, well it was kinda cold and i started pushing 15lbs! No boost cut but I dont want to, I may have a leak but I was wondering if ne body has had simliar occurences.

RE: Thread hi-jack.

I usually run mine at 12psi, but i've noticed that at times boost does increase all of a sudden. I dont have boost cut on mine, so that's probably why it's able to boost that high sometimes.

But i'm still not exactly sure why it does that when i'm not messing with the settings on the boost controller.

Maybe the motor's giving me a sign to upgrade the turbo already. 0_o

[Supersprynt]

I'm afraid its boost leak, but i'll take her out when i get home to see if its gone back to normal.

15psi is like whoa tho.

I have researched this a bit for my GT4. Well the tmic is quite good but if you upgrade your car and tune it for more than 400bhp the tmic will not be sufficient and you will need a fmic as you dont really have a choice on size for the tmic.

[Bizerk96]

Got a query, Is it possible to keep the fog lights in when you do the FMIC. I know that's the route i want to go but if i can keep the fogs, i'd really like to.

[celicaspeed]

Most guys I see that have the 3s motor run a stupid amount of piping not thinking of the shortest rout will make the most power!On my ct26 I shaved off the spots were the turbo mounts and turned the turbo housing almost 180 degrees to the rad.and I moved the actuator2 spots so it sits in the same place in the car but the turbo faces forward instead of up towards the tmic.Now I only have a 90 bend into a 180 bend into the intercooler and it comes out of th ic and does a 90 bend to a 45 up to a 90 and staight to my intake.The quickest way to cool the air the better.The less the bends the better!!!I also used a 2.5 in into my intake and from the turbo into the fmic I used 2in.Much more pressure, more horse!!!3 in into the turbo with a rubber reducer to 2.5.

[spunky393]

you got pictures celicaspeed, i would really like to see that setup

[Supersprynt]

its not that nobody knows that shorter piping is better its the fact that theres alot to work around. Do you have a 3s or a turbo? Theres no details or pics in ur profile.
