the hks fmic is huge i have a 99 spec bumper and dont know if will receive the proper amount of air in there what you guy think will be enough? or maybe upgrade to another bumper.

thanks

 

Its fine.

 

13bmaniac, not to second guess you, but your primary concern should be is a FMIC the best setup for your car. If you're drag racing, yes. Otherwise, a FMIC isn't the greatest idea, since it'll quickly allow heatsoak, and blocks fresh air from reaching the radiator. If you do any normal street driving or auto-x/roadcourses, a large SMIC or V-Mount would be a much better way to go, which allow the radiator to see fresh air.

why would a fmic heatsoak any faster than a large smic.

My fmic is never even warm on the outlet side after driving, and drove her all sumer with the stock radiator with no issues. Than again im single turbo with a dry center.

 

I dont completely agree (although you are right for the most part). But I have seen some ice cold running FDs with a large radiator mounted directly behind a FMIC mounted upright.

 

Well you'd think by upgrading the radiator, although with an FMIC you might block some air-flow...the actual efficiency of the thicker-cored radiator kind of makes up for that, no?

 

And wouldn't an SMIC heatsoak much quicker than an FMIC since the FMIC is directly inline with the airflow?

 

FMIC don't get heat soaked when compared with SMIC or V-mount.

The 99' spec nose opening is 50% larger than the stock one you will be fine.

 

There is not enough of a difference to worry about it.. You should be worried about the size (volume) of the intercooler as to the size of the turbo.. Eg.. Smaller for stok turbos larger for a big turbo. I am running a custom FMIC w/ the stock turbos and it is smaller in size than any I have ever seen.. It works great for response time and no pressure drop.. Make sure your cooling system is in A+ shape in any event on these cars. Never see above 90c in stop and go in FL in summer time. G

 

From what i've seen on this forum most people with overheating problems with FMICs have no ducting at all around their rad. Just because the air goes into the fascia opening doesn't mean it will go through your FMIC. Air is dumb, you need to encourage it to go where you want it. closing off ratholes between the fascia and the FMIC is a must.

It's similar for the radiator, you want it to be ducted to the incoming air as well. After the air successfully makes it through the intercooler (as in G's 3rd Gen picture above the air is mostly going to go around the rad. Apparently, in G's cas there is enough air making it through to keep it cool, but it's not an efficient setup. The FMIC exit air should be ducted to the rad, or another source of fresh air should be used but also ducted. At the very least you want to separate the air exiting the radiator from the air entering the radiator so recirculation doesn't occur (hot air looping around to the front and being passed through the rad again).

To sum it up, air is dumb. It takes the path of least resistance. I think people not realizing that are the main reasons FMICs have a bad reputation on here.

 

We have probably installed at least 50 Front mount setups and we have never had one over heat due to lack of air to the radiator. If you use your car on a roadcourse then I would go with a SMIC or Vmount, otherwise you wont have any overheating issues with a FMIC.
