Biggest intercooler I have ever seen

[fast924S]

So, on my random searching on the internet I cam accross this

"This Topless Speed Demon is not for the faint at heart. She is set up with 3.6L Twin Turbo Engine with Two Garret T3 and T4 Hybrids, Custom Intercooler, Split Second Fuel Management, Custom Exhaust System that all snap your head back with 550HP".

I know I know its not a 944/924 but god Look at how big those intercoolers are



Where do people get the money, I bust my A$$ every day working on toyota's and I cant even afford to make a sick 924S

Different car but I love the wheels

[Makenzie71]

ha...that's probably only like 3X12X24...lol

[CJFusco]

mmmm 993

My guess is it's about 6 inches thick (the intercooler piping is probably 3", and it looks about twice that), and I have no idea on width or length, but that is one BIG intercooler!!

[VINMAN]

Thats a big a** piece of aluminum!!

[will944]

These are no joke either.....

Where would you need such an intercooler for?? It looks 'cool', but I don't think it has any use. The size of intercoolers must be calculated with all sorts of variables concerning airflow and pressure. A big intercooler will certainly reduce the responsiveness of a car and will have little effect on the performance of the car. The best thing to do is to install an intercooler of the right size with the best efficiency around (construction and material of the part). Bigger isn't better and i think he could have spent his money on a proper upgrade...

Agreed! For the crowd with more money than time to think about such things.



What might the size of the intercooler be overcompensating for???

that intercooler is that big for 2 reasons. One, hes prolly pushing an insane amount of boost, and high boost generates a lot of heat, requiring a bigger intercooler to keep the temps down. Second, I cant imagine intercoolers on a 911 being more efficient than a front mounted on on say, an Eclipse or something, so you would need a bigger intercooler to grab more air coming off the roof.

I work in the automotive industry dealing with turbo'd cars, and intercooler is huge, but by far it isnt the biggest ive seen. The Liquid to air intercooler sitting on the front of Lisa Kubos drag Saturn dwarfs that one. I could prolly fit inside of it..its that big.

I agree with Blue. Its not some guy just installing some big intercooler. That 6 cyclinder is pushing 550 HP Im sure the boost is crazy and the location isnt the best for airflow but it might be all they had to work with. Therefor with large amounts of boost mybe 22psi and up and with a poor location for air flow, you would need a bigger intercooler to drop the intake temps in that type of setup. Also dont forget you can design the turbo setup around the intercooler. This way you wont have large amounts of turbo lag and everything will work right. Im sure that that setup he is running is well designed, we just dont know all the variables that went into it.

also, its not like we are dealing with 10 feet or more of intercooler piping like subaru WRXs do with front mount kits (a total waste of money). It comes out of the turbo, up into the interooler, and out the middle into the throttle body,much like a factory WRX does. I favor top mounts over front mounts because they offer the same amount of boost lag as the OEM intercooler (which is little to none because the air only travels less than 2.5 feet to get to the intercooler.


That 911 maybe has 3 or 4 feet of piping....thats both turbos. That isnt much. That also isnt much distance to cool the air down before it enters the motor. With an intercooler like that you can sufficiently bring charge temps down.

And when you have 2 t3/t4 hybrids powering a 6 cylinder....thats one turbo for 3 cylinders. you can get t3/t4 turbos from anywhere from a 48 trim exhaust wheel to a 63, the larger being more laggy but providing more top end. I can properly spool a 57 trim on my tiny little 1.6L bottom end in the colt, and get at least 12 lbs of boost by 3500 rpm. if you do the math, two of my motors equates to a 3.2L. Still smaller than that 3.6L.

a t3/t4 turbo is also quite large but not huge like the T series from turbonetics or garrett. The compressor efficiency maps dont peak until the turbo is making 20-25lbs of boost. If you dont plan on running anything more than that, then you dont need a turbo that big.


That car prolly makes well over 550 hp as well. We made over 500 crank on a 4 cylinder with a 60-1 turbo.

Hey blue, I have been doing some reading in a book about Nitrous, Supercharging and Turbo, How do you read turbo efficiency maps???
