Smic

OK, here's a question for you, I am considering fully decatting my uk tt & was considering putting another SMIC on the car as the old one is starting to fall apart. Research shows that you obviously need good air flow thru the SMIC so why did Toyota mount a huge indicater here, which blocks off approx. a third of the hole?

(or am i missing the point somewhere ?)

I seem to remember Chris Wilson answering this ages ago. The indicator doesn't cause a restriction at all. Toyota designed the ducting to really enclose the SMIC and the spinning of the wheel behind the vents draws air through the intercooler as well.

I'm sure someone will come up with a better description though. I will try and find the thread ....

It's not a bad idea to have an inlet surface area smaller than the surface area of your intercooler, because this will slow down the air speed travelling through the core.

The slower the air (to a point) travelling through the core the better it will conduct heat away from the core.

But i still think them damn orange blobs were an afterthought!

This is a god site for explaining few things about the 2JZGTE. this shows the theory behind the SMIC location and ducting...

WOW, my head hurts, (good link)thanks for that very useful info. So new SMIC to be found ! ! ! does anyone know how much bhp a stock SMIC is good for ?
(p.s. I don't like the orange blobs either !!!)

well i'm gettin a quote for a smic made for me tomorrow by pro alloy they are makin some really good intercoolers at the moment they have been making rs500 intercoolers that out perform fords one

ok, cheers for that Mad Woody, let me know how much they sting you for as they may get another one to do !!

cant the o/e smic be recored for a sensible amount of dosh ?

The indicator doesn't help the flow, for sure, if you want put it elsewhere, it can only help. I am having a final batch of my uprated SMIC's made in Germany, 3 are pre sold, 3 are left, and they are 620 each, plus P&P. The stock ones cannot be re cored. Mine are all alloy, see below:

Is your intercooler falling apart, the fins corroded off the tubes?
If so, its efficiency will be extremely degraded. Running more boost
than stock? Is this a good idea? NO! It's not even a good idea running
STOCK boost with an I/C like that, and when the weather struggles above
freezing it will be a VERY BAD idea! Don't want to spend over 1400
quid on a new quality front mount intercooler, only to have half of
it masked by the aperture in the front stock bumper being too small to
allow air through all the core? Even with a new aftermarket bumper that
probably fits where it touches, (from what I have seen of most Jap
products), the air will just take the easy route AROUND the expensive
FMIC, rather than through it, because no ducting provision is made. The
answer is my uprated, all aluminium stock mount intercooler. It uses all
original mountings, and the original factory sealed ducting. It uses a
state of the art core with fine pitched finning, on modern tubes with
internal turbulators. The core uses 10% more tubes than the stock unit,
too. The quality of its construction is superb, and all are fully leak
tested under pressure before despatch. Pressure drop, both internally
through the core, and aerodynamically, are less than the stock cores,
making for a very efficient unit.

Pics of the intercooler are available by e-mail, or at :
ftp://ftp.chriswilson.tv/intercooler

There are plenty of people on the MKIV Supras forums who have bought these
for an independent appraisal.

They will sell for 620 pounds, there is no VAT to pay.

Postage and packing to UK mainland addresses is 12.50, the package is
bulky due to their fragile nature.
