I'm going single in a few weeks. I don't know which kit i'm going with yet, but i'm working through that.
My question is whether to go with a front mount IC or an M2 medium stock mount.
It seems most people run with the front mount. But, I know there are people running the stock mount.
Any opinions........tales of woe.........lag issues.......or other relative comments?
Thanks

 

I have to4s with M2 Med and it works great. I put down 465 with it. Intake temps are fine and it flows better than the FMIC. No need to go FM unless you want the bling.

 

SHUT UP!

 

Whats the exact specs of your turbo? What psi did you get the 465?

 

Oh yeah, and make sure you buy your SMIC from RX-7 Store!

The only specs I know are 1.00 exhaust A/R. That was at 18lbs. Maybe jason knows more about the XS kit.

 

Hm, is that a 60-1 compressor wheel? I am asking because I'd love to get 450rwhp at 18psi with a 62-1 with a .96 turbine side.

 

i think for street driving a FMIC is better. when you go single you will notice your water temps drop dramatically anyways so overheating really isn't an issue.

I currently run a large SMIC with my single because of all the hype of overheating and etc... but now I wish I had gone for a FMIC

 

Yeah, I searched, and some of the older threads had a couple of people saying that the front mount was better for street.
How often do you drive your 7 Radkins? Everyday? Mine will be everyday for at least a year(while a build up my Monte), and I will be sitting in traffic everyday.

 

I drive mine a few days a week when it's nice (like today). I wouldn't say overheating is hype, it's the laws of physics. If you track the car at all you will find that out quickly.

 

Well, people were saying that the SMIC was better for track. I will be tracking mine from time to time, but it will get used more often on the street.
I guess i'm leaning towards the stock mount though.

 

I wouldn't say overheating is hype, but with a good coolant system it shouldn't be a concern with a fmic. I have a greddy and I see no overheating issues at all, but I do have a fluidyne radiator as well. When setup properly and everything working correctly a fmic is better than smic. It will cool your intake charge better and you shouldn't see a problem with overheating at all.

 

For city use, a SMIC heat soaks more than a FMIC, and also takes longer to cool back down.

I live in Houston, and love my FMIC as the AC keeps it cool even in stop and go driving. A SMIC in this same condiiton gets hotter.

 

IMO its give and take. With a fmic, your intake charge will be cooler. With a SMIC, your engine temp will be cooler. As long as my engine temp is good, I will always take the cooler intake charge.

 

I like the fact that one more thing is out of the engine bay
I hate it when I see some peoples single setups and it looks more clustered than a bolt on twins car.

just make sure you get a good one some have dumb mounting points and require cutting and also rediculous curves in the end tanks. make it clean out of the way and a straight shot for the intercooler pipes

i like the fmic I generally see 40 air temps in the city and lowest was 29 on the highway after about an hour

to me single turbo goes with front mount and clean *** engine bay with nothing but what you need

 

which front mount are you using and what are the ambient temps on those conditions?

 

Well, let me ask this.........
How much does a vented hood affect the temps? Say someone was to get a SMIC, and a vented hood. Would that make that much a difffirence when it came to stand still traffic Heat soak?

 

You AC keeps you IC cool? I don't get it.

 

I think he's saying that he turns the fans on early by using the AC.

 

Alot of heat soak comes from inside the piping from the turbo itself, not just radiant heat from the engine. SMIC's are usually mounted above the turbo so that's where the heat ends up. You guys with front mounts, what to your air temps rise to if you park the car for 1/2 hour and it is say 80F ambient temps?

 

So actually, a vented hood would be more beneficial to the guys running FMIC's that complain about over heating at the track?
Not in this thread, but I did read that guys were having problems after repeated hot laps.......and that they couldn't get the car to cool down.

 

I run a modified old school greddy 3 row not the newest but before that one

the outlet was facing hardleft to meet the stock elbow I guess and we cut it off and repositioned it so its a straight shot

Im in florida so its around 85 degrees most of the time

From what I have read and seen in person a vented hood benefits guys that fun V-mount IC setups more than any other type. I don't know if that was one of your considerations or not though.

As far as FMIC's go, I have several friends who run them and not one of them has a problem with overheating. And just to make that relavent, all of the cars I'm talking about are daily driven cars. Best of luck to you in making your decision.

I had a M2 med before I got my Greddy Front mount 2 row R spec core.
I noticed much lower temps with my Front mount. Also my Stock mount would heat soak like a ***** in stop and go traffic. The benefit of a stock mount is it wont get damaged from a bump in a parking lot or a rock off a dump truck on the highway/varmit running across road. Wont interfear with radiator cooling on a track setting and will have less pressure drop which helps slightly with turbo lag.
Nothing will cool as well as a front mount. But there is 10x more labor to install it. Plumbing and fitment can be tricky. Looks real sweet also

 

I bought the greddy 2 row FMIC for my stock twins. Now that I have a TO4R in the mix, I will be using that core, relocating the inlet and outlet, and making my own custom v-mount. Koyo rad for it and FAL fans. Also extensive ductwork to provide efficient flow. Just my thoughts, good luck with your decision buddy.
