Can anyone give their experience concerning throttle response of their front mounted IC? I'm debating over an Apexi front mount and M2s large stock mount... Does all that IC piping produce noticeable throttle lag or not?

Much appreciated.

**** cheap little stock mounts. go all out and get a front mount. they dont soak all that heat from sitting right in that hot *** engine bay.

i drove a friends car(smic)...came back and we drove mines (fmic)

no significant difference in throttle response on the butt dyno.

If you plan on tracking your car even just a little bit, get a SMIC. One lap on the track with a FMIC and you FD will be ready to call it quits for the day. FMIC is only good for the cool factor on the street and plus is sits out there to catch all the crap coming into the nose of the car.

I had the Greddy SMIC first with my non-seq engine. Now I have the Blitz FMIC which is over 2 times larger than the Greddy.

I did not notice any difference in throttle response.

Chuck,

Would you give us a little bit of information on your experience?

1. What was the performance difference between stock intercooler and GReddy SMIC (intake temps, dyno, perception, boost, etc. - whatever useful info you may have)?
2. What was the performance difference between the GReddy SMIC and the Blitz FMIC?

Thanks. Much appreciated.

Matt,

The Greddy SMIC is about twice the size of the stock one in frontal area and is also thicker. I do not have any dyno numbers, but besides the greater cooling it also has more hint sink capacity. It is compareable to the PFS and small Pettit ICs. Back about 5 years ago when there wasn't much else available, there were a few FDs making about 350 reliable RWHP with these.
It's advantage is ease of installation and can be used with stock
piping. It's disadvantage is heat soak in traffic and less cooling than other now available ICs. Would be fine for up north where it does not get that hot during summer. I live in Houston.

The Blitz FMIC and Greddy FMIC are about equal. Both are over twice as big as the Greddy SMIC. There are harder to install and might require different piping. They do not heat soak but reduce air flow to the radiator and can cause higher water temps. Their
advantage is ability to cool a lot more under all driving conditions
and thus not only produce more HP but lower and safer intake charge temps. Thus helping to prevent detonation. Here in the summer time, it makes a difference in power and safety.

It also depends on your total engine mods and how much boost you are running. A lightly modded engine would not need a big FMIC.

My ASP Race IC, is neither cheap or small. Infact its one of the biggest IC kits you can get. Works as well as a FMIC with my ducting and fan, and it keeps my car from overheating.

could you elaborate a little? thanks.

A FMIC with a stock rad will most likely overheat at sustained high speeds due to the FMIC restriciting air flow to the POS stock rad.

FMICs due restrict air flow through the rad some. In some cases even with larger rads, the engine might overheat. It all depends on design of the complete system.

My stock rad with SMIC Greddy and without the fan mod would easily reach 200F going about 90MPH here in Houston in the summer. That is no where racing speeds or power useage.

Of course that was a gross overstatement by JOHNSRX7.

the reason why i like the Apex'i cores is because they have a delta fin design.
