FMIC or SMIC?

[Spooled]

Any problems with scooping up water/dirt/etc?

I was going to make one.... just one of those things I never ended up doing though. I just got around to that lower air duct thing for the intake, that was easier to do.

Nope... I've posted a bunch of info about it before. Don't know what I'd search for to track it down though.

the turbohoses setup will cost about 1050 while fmic kits like the hiboost or begi will run about 900 depending on the options. i dont see how you are saving money by going with the side mount

i and several of the other chicago people made several competent suggestions of where you should go with the car, on everything from wheels to cams. i have plenty of documentation showing that you ignored a good deal of that advice from myself personally in the form of emails and pm. i could wade through all 8600 messages in my inbox to find them all but my reputation here speaks to that without requiring me to produce proof and waste anyones time, my own included. "real" vendor? perhaps you should have been a "real" customer instead of an incompetent ricer, on this forum and over on vboard.

What do you have to base that on?

to me this thread reminds me of the mpnick upgrade vs gt28rs.speculation.

........Unless you do comparative tests with controls theres nothing to be said about either unit comparatively.

I would like to see a comparison done.

What would be the best way or scenario's(s) to make a good comparison other than HP vs HP? I imagine doing several runs of different time lengths and measuring the temps on various parts of the IC & piping would be a good start. Is there an accurate device that could be used to measure air temp in the charge/cold side piping while driving and possibly datalog it?

FMIC all the way.

Actually the best set-up is neither one!!
Liquid-cooled intercooler, that's by far the best!
You get the shortest path with the pipes (straight from the turbo to the TB) and you can put a huge radiator where the stock SMIC goes. Works as well when the car is idling... And it's not that much more expensive than a FMIC (maybe even cheaper)

 

[terbow]

Its almost the same price if you set it up for daily drivers. You need a larger Core than where the smic is.

I had one sort of. I never finished it. I have a water tank thats shaped like the stock SMIC, and i used a lightning aftermarket Heat Exchanger. The spearco air/water units are very pricey.

I could have gotten away with sub par components and made it cheaper but for traffic and a daily driver the air/air unit is better.

plus the cost of fittings, sufficient pump, lines, etc. it adds up to be more. I wish i did it if i didnt have to drive so much traffic. Once the water in the tank warms up it becomes very inefficient. (tank size is also a factor)

its a great idea, just a big pain for daily use.

I'm not criticising, but what does that really mean? Is that the max air it can flow or the opint of diminishing returns? Or is that where it can't pull enough heat out? And how does it compare to an FMIC on a car at 250hp? Will the SMIC be struggling both with flow and heat while the FMIC is fine? The reason I'm asking is because the FMIC may make it easier to get 250hp (ie - at a lower boost level). Again, I'm not criticising, I'm just interested.

Well now we are getting into air flow dynamics and this is not my strong suit. So what I am about to say could be incorrect, but I am pretty sure I am right.

The FMIC is going to require more piping and is going to be more space for the turbo to pressurize. An FMIC on stock boost may make the air cooler but the turbo is going to boost up and then quickly drop off or struggle to boost up at all (lag). I am not terribly sure how it would work. And once again I could be wrong all together on this but, it would be like trying to inflate a king size air bed with your mouth.

As for the SMIC, there is an equation floating around that coorlates HP with airflow assuming stoich mix. And basically, the if you want to run 250 HP, you would X amount of airflow. Then there is another equation on the IC theory sites that explain that for X amount of airflow, your IC would need to have Y amount of cubic inches to effectively cool it Z amount of degrees.

If you try to push too much air through a small IC, it simply wouldn't spend a long enough duration in the IC to amount to any cooling. Kind of the same reason why trucks have larger radiators than passenger cars. More water flow needs more space to be cooled in.

Hope my gibberish makesw sence! LOL!

 

[Spooled]

Well
.......

Cool, I'll have to look around for those equations. It's interesting stuff and I totally see your point about the tiny stock turbo struggling to pressurize a larger volume.

genius, just out of curiosity, have you dynoed your setup yet?

No. Quite frankly I am afraid to. It hasn't been pulling as hard lately since I accidently slipped the clutch at a gas station and shook it up really hard. I am hoping that it is my couplings leaking. The turbo is spooling real quickly and I am not getting as much power as I should.

The T-bolt clamps are tightened all the way to their limits but I can tell they are still a about a hair too big. I ordered the correct size last week and am hoping that will eliminate my problems. I am also still using worm clamps in a few places and they are stripping. If someone has a story of noticing a drastic improvement after tightening the clamps, it would bring comfort

Also, you know where the factory location is for the MAF? Well after I took it off, I simply stuck the K&N cone at that spot with the IAT tucked inside on stock intake pipe. I KNOW that is not helping at all!

So before I run to the neighborhood dyno, I would like to change out the intake and atleast make sure my couplings are on good. Here on the MS coast there are no shops around but I am moving to FOrt Walton Beach, FL and hopefully I can find one down there after I get my stuff straightened out.

LOL! Just imagine his voice reading my posts.

I was at a huge radio station-sponsored Halloween bash in Detroit and there was some guy dressed as Napoleon Dynamite who pulled it off well. It throws you off.
