When I flushed this new FMIC clean, I used an old hair blow dryer to dry the interior. I just stuck the dryer nozzle in one end & let it run. The discharge side had almost as much air flowing out of it as what was being blown into it. When I tried this before on my OEM IC, the discharge was noticeably less. It would be interesting to run a differential pressure gauge on this cooler. I'm betting there is very little loss across the core. Something else that was interesting was the amount of the core that warmed up. The dryer was only able to heat about 1/2 of the core. The amount of warmth was very even from top to bottom & flowed about 1/2 way across. I needed to swap the dryer to the other side to warm the other 1/2 up. This is all very unscientific but it was obvious to the touch that the heat exchanger flowed very evenly & gave up its heat easily.

The smaller one. IC-325 I started the car & let it idle until warm-up. Never exceeded 170 while reving & the fan would bring it right back to 162.

So does the intercooler cover any of the fins (core) on your radiator or is it the same size with nothing blocking flow to radiator? Did it affect your boost or amount of boost with going to a bigger intercooler and longer pipes?

The IC tanks are well to each side of the other heat exchangers so nothing solid blocks any flow.

I can't answer your second question. I don't have a boost gauge & I haven't driven the car yet. Other than this cooler, my car is mostly stock. I would think that my boost may have gone down somewhat due to less restriction to flow. I'm hoping that I can now dial in more boost. My concern was throttle response & any possible lag due to such a large volume as compared to the OEM IC. The new heat exchanger is huge as compared to the original & far more than I need. I have plenty of room to grow from here.

That too is my concern, throttle response and is there any lag trying to fill up all that extra volume. Let us know how it is once you get it out and driving.

Really?

Throttle response and Turbo lag worries?

Are you guys sporting Turbos off of a 1981 Volvo?

Come On Man!!!!!!!! :confused:

If it somehow, magically rears it's ugly head, you can prolly tune around it, doncha think?

I'm jus' sayin.......:rolleyes:

Thats why we have this site is to ask questions. This isn't a smart ass forum. And yes my turbo is the size of a 1981 volvo. Thats why I asked because I have a small turbo and have read that with a fmic you need to bump boost up to get where you was before. And if I bump boost up too much, I would get alot more backpressure on my exhaust side.
 
Anyone have pictures of the RJC intercooler?

Nix

She's a MONSTER....

I wasn't being a smart ass.

I was stating the obvious.

Your concerns with my logic lack merit and are unfounded.

The FMIC is about 2 cu. ft. larger with new pipes.

If your turbo can't keep up, then upgrade the G-dang turbo, don't call out those those who have made the investment im their cars.

Why wouldn't you just plan to do that at the same time you plan to upgrade to the FMIC anyway.....

You want to realize the gains available to you from the new FMIC, don't you, or do you want to have one cuz it looks cool?

I don't have all the knowledge on these cars so thats why we asked the question, I'm not as smart as you are.

I didn't call out anyone sounds like you are calling out because I'm not as rich as you are and it takes me more time to get there.

Can't afford to upgrade turbo and fmic at same time. I was wanting to do fmic first then get turbo later. Don't want a bigger turbo and too small of a intercooler.

Yes I want to know the gains of the fmic, thats why I asked the question that you thought was obvious. Don't want it for cool factor, $1000 for being cool isn't smart. For now I have a small turbo and do plan on going bigger next year.

This will be the last time I discuss this with you, I'm not going to hijack this tread to argue, both I and JM have the same questions.
 
I'm likely more naive than you about TR's.

I only know that the upgrades I have done using info gained here have proven to be succesful.

You both asked questions and got straight up, honest answers from me.

Actually, I avoided one and JM pressed it. When I answered, you stepped in and cried foul.

Where's the malfunction here?

By the way, I work really hard for my money just like you, and none of it comes easy so don't try to go there, cuz that is just pure, unadulterated BS.

All I said was it was great upgrade and you wouldn't see significant losses in spool, boost or throttle response if you decided to do it.

You escalated it from there and then go and try to play the martyr.

Nice try, but it ain't workin'.


I'm done too.
 
The bigger one is the same size just a 1.5 inches thicker. Wish my car would accommodate a front mount but theres no room between my header panel and core support. 2dr malibu
 
Now, Now, everyone time to play nice. Lots of people are reading this thread.

I can't imagine trying to squeeze the larger cooler into position. There isn't much room between the grill & my IC as it stands. The IC-475 must be positioned closer to the A/C condenser to fit.

Yes, that large of an intercooler on a stock car is a waste of time and money unless you are upgrading. Your lag will be quite extensive especially with a stock or small turbo. Many on here with years of input have earned the right to smart ass status. Some newer members think it is a right, right off the bat and leave a bad taste to many members. Spending thousands having someone else build your car by far does not make you an expert, something some should keep in mind.

I've seen a Malibu with an FMIC. I believe it was an eBay Chinese IC. By any chance did you see the PINKS episode with the Malibu that raced the Camaro out of Canada. That was the Malibu I was checking out with the FMIC. On one of the latter runs the IC ruptured due to too much boost. They were able to weld it back up fairly easy. If you want more info, look for 1kwikbu on the Yellowbullet forums. He was the owner/builder of the car.
