Default Front Mount peeps

Ok, so I've been debating about which way I should go. I was thinking either straight front mount, or a top mount with a mild water/meth mix, say 80% water 20% meth to drop the temps.

I was leaning towards the top mount due to the restricted airflow to the radiator when installing a front mount. If I lived anywhere else but AZ, I don't think it would be as much of an issue. Does anyone here have a frontmount that has logged their coolant temps after the install? Currently mine fluctuate anywhere between 190-200 after the cars warmed up and I'm cruising.

If you cut out the bumper enough, you shouldn't have a problem. The key is cutting out enough for the air to flow over the top of the FMIC and into the radiator. My coolant temps stay right around where yours are, maybe a few degrees warmer.

My vote goes to FMIC.

Back on topic:

Sounds like you shouldn't have any major cooling issues with a FMIC, but from my experience if you're going to go with water / meth injection going FMIC is kind of pointless because you will be cooling your air charge alot just with the injection. My experience is only from my Buick Grand National, but even with my stock IC (behind the radiator) my meth injection cools the air charge plenty by itself.

My vote: If you don't want to deal with alky injection and have a big turbo, go FMIC.

If you are going alky injection 100%, have your cake and eat it too. Get a big TMIC and run Water / Meth. Cold intake temps plus less lag FTMFW!!

For some reason I always assume everybody has a big turbo. If you have stock turbo, I would really lean towards meth injection. Or a bigger turbo/FMIC.

I noticed higher temps and decreased ac performance with a APS dr525 which is still a pretty thick fm like the older dr725.The very first thing I noticed with the aps was it changed the handling of the car due to weight below bumper.The car was not as quick on turns.If I still had the car I would either stay with tmic or get a smaler lighter fmic.I have sold the car but this summer I installed a bigger Koyo radiator and it has helped a lot.

When I put my txs on, I found that my car ran hotter, but I also did a pretty poor job of cutting the front bumper to allow airflow. I think the 2006-2007's have less frontal area. After running just a bit warm on average, I cut the front bumper more aggressively to increase airflow. That seems to have done the trick as my engine now runs where it did before I intalled the FMIC, even with a loaded down car and full AC.

I noticed 10* hotter coolant temps with my Perrin FMIC with the stock 02 radiator, but the old radiator is known to suck. With my PWR radiator its back to normal operating temps, in comparison to the TMICs i've had. AC still blows cold.

IMO to get the best of both worlds of cooler intake temps and stable coolant temps, in AZ at least, a FMIC and an upgraded radiator should go hand in hand.

So... adding weight to a car, and thereby changing the weight balance, especially when its past an axle (you know what a lever is, don't you?), doesn't alter handling? Physics be damned.

I would imagine that it would, but not drastically.

Your imagination isn't required for Newton's laws of motion to remain true. If something isn't drastic, there isn't a perceptible, quantifiable difference?

haha. I agree with you, but to the normal person, who's car isn't stripped down and still has a rather weak weight distribution, I don't think you would realize a front mount.

So you think you know how other people sense the world around them? You are intimately knowledgeable of 2TG8V's perceptive thresholds, and the configuration of his car? All you can say for sure is, you don't think YOU would realize the difference. Don't be so cocksure others can't.

Since when are these forums populated by normal people anyway? Most of our automotive interests and knowledge are well outside the Gaussian distribution.

I don't know what I think about the FMIC and weight distribution yet. I have made these observations though:

The bumper beam I removed is heavier than the IC I put in it's place. It is not significantly heavier though, maybe a couple of pounds tops.

The top of the IC sits approximately even with the top of where the bumper beam used to sit. It may sit (the ic) slightly higher by about an inch.

The IC and the bumper beam stuck out by about the same amount.

The bumper beam is wider than the IC.

Based on these observations, I would tend to conclude that the IC would have a slightly lower center of gravity as compared to the bumper. I would think this might only impact turn-in slightly and it is unclear to me if it would make it any worse as a lower center of gravity can improve a cars feel by lowering it's effective roll-center.

I would also think it may improve handling characteristics because it is not as wide as the bumper beam and therefore has a lower rotational inertia impact as compared to the bumper beam. This would make the car seem more "flickable" or aid in quicker transitions between right and left cornering with less overall roll.

Just my observations on my TXS FMIC. Others may be different.

I'm with you on the center of gravity theory, but its more complicated than that. We have the vehicle's sagittal, coronal, and transverse planes to consider. The wider bumper beam distributes mass from the pivot point moving the center of mass out and reducing the angular velocity. Maybe if I paid more attention to those advanced math courses and had any real interest whatsoever, we could fully model the dynamic system motion.

But none of that was my point. It was more simple: we can't claim with any absolute what someone else is going to sense. I know I'm not attentive enough, but would never attempt to claim someone else isn't.

We could model this, but I would have to dig out my dynanics notes and brush off the matlab skills as it's been a few months since I've touched that software. Also, without having a wildly accurate model of the car to play with, we'd be making a whole lot of assumptions and it would likely tell us not much about this specific vehicle. It might show a bit of theory though. I could ask my buddy who's studying vehicle dynamics at stanford right now. I know he had some wild transfer equations he was working on for a generic car model.

But I do sort of see what Kyle was getting at. There are A LOT of people on these board who wouldn't know/perceive even the largest of changes to the way their car handles. This is the reason we see all sorts of goofy ass suspension setups that fly in the face of common sense and physics yet the people swear it improves their car's performance eleventy billion percent.

But it is wrong to assume everyone is like this.

Yes I know I'm wrong, and I stand corrected. But I think DroppedClutch is just bent at me for my "geeks" comment in his thread about Win7. That was me picking on everyone in the thread I knew, not a personal stab at you.

But Back on topic here, I don't want the OP diverted from buying a FMIC because someone claims they can notice a difference. Yes, there might be a slight difference, but realistically, on a day to day basis, you're not going to notice it.

There you go making unfounded assumptions again, if you think I think "geek" is anything but positive. Check out what I'm I'm drinking my Jamaican Blue from...

No doubt; no matter how much we model and analyse in Maple and Matlab we could never model for the human reaction to the changes.

BoT: I saw my temps go up a bit. If I did it over, I think I'd stick with my Spearco TMIC and do staggered meth setup. Instead, I'm just going to do it on my FMIC setup.

I am 100% sure there was a handling difference,it has relation to the overhang of the intercooler below the beam

Im just stating my personal experience,I had 15k on the car before installing the fmic.Its ok if you dont agree.I know what I felt.

keyboard warrior... get off your googling high horse.. i had the dr525 and it weighs like 20 pounds...

on that note you're going to now tell me my car handled differently because I had a optima red top which weighs a bit more too right?

oh and if anything, you got rid of weight.. the stock bumper beam weighs way more than any intercooler setup
