Q: too big intercooler!
Hi!
I bought ssautochrome huge front mount intercooler 24x12x4. My friends told to me that it is overkill to my 13b-re. I build turbo upgrade with turbonetics T61 turbo, 1.5 bar max boost, 8000 max rpm, porting. Are my friends right?

There are lots of people smarter than me on this; let's hope they chime in, and do a better job than I do. Bigger is not necessarily better. The bigger the IC and the longer the pipes, the more volume you have to fill before you get boost to the engine. IMO, you should run the smallest IC that is rated for the CFM your turbo will put out. The rest just increases lag.

maybe you heard the welds suck?
well i own the 3" deep bar and plate one.... 24x12x3 and the welds are beautiful... the IC was shipped to my door the next day....
but its bad.... for some reason.
im sorry to open this can of worms AGAIN... but maybe thig guy has some info we should all know about.

its not the size that would be to big to make a concern, but if it has a large pressure drop.
a friend of mine has the 4" version and has run a 9.9 on it so it will do fine fo anything a spinner can throw at it.

well don't forget that it's a Bar & plate IC.. if it was a tube & Fin I'd say you were in the ball park with it. but with thr bar & Plate you've outsized yourself too much the flow rate thorugh the IC will only become effectively cooled at the very top end of your power band. They flow way too fast and are not as thermally eff. with under capacity flow. Also 4" deep is not helping your cause, by the time the air is 1/2 way through the IC the temp differential between ambient and internal is about even.. so that other 2 " is just for storage capacity now. Water spray or C02 spray is NOW your best friend. Then thier is the issue of lag, that's a huge volume to pressureize and I belevie that the SSA is 3" in/out so if your whole IC piping setup is 3" as well... this is allot of volume for a poor little T61 to fill..

My Greddy 3 row i more to the passenger side for the radiator & oil coolers to get close to the same amount of air
On a side note. i wouldnt have bought it because of SS autochrome. they have a reputation of selling crappy parts that last weeks. (espically there mainfolds)

Mig welds might not be pretty, but this manifold isn't breaking.
The rest of their products fit well and work great, if they made their welds a bit better on the manifolds, they would be very good.

Bigger is not always better is correct.... You will get pressure drop and more lag. Plus those intercoolers are so big, size really has no effect on the cooling.. its how many fins it has to cool the air. And those cheap ones are big with only 4 or 5 rows. You could have a smaller intecooler and be much more efficent then those big ones..
