MSP air-water intercooler project

(This is the 600hp kit from www.frozenboost.com, with the type 8 IC core, type 118 radiator and install kit)


***Update 4/14/09 - Initial install***

So far this week, I've got a good chunk of the fitting and routing done. Here are some pics of the progress so far....


First thing I did was relocate the power steering cooler line to behind the hood latch support to free up a little clearance behind the bumper. The lines are metal, but they are connected to the pump with rubber hose, so there's a bit of play in them. I left the two brackets in the engine bay unbolted for the time being, since the holes no longer line up and it seems like everything is supported decently without them.




Next up was cutting a notch in the bumper bar to give the radiator cleanrance. I just traced the outline of the foam support and cut that out, and figured I'd cut more if need be.




Figuring out the best way to mount the radiator was what has taken the most time so far. I quickly realized that my first idea (based on guestimating the space behind the bumper) was not going to work. So I took a few more measurements, and decided to mount the radiator slightly set back from the back of the bumper bar, using some washers as spacers. The downside to this is that I'm not going to have clearance to mount the included fan behind the radiator... Depending on how the bumper fits all said and done, I may adjust the mounting, and/or look for a nice slim fan or two.



My plan for mounting is to support the radiator from the top, using the two mounting tabs on the top. However, it makes for a fairly unstable setup, since the radiator is free to swing forward and backward somewhat. To address this, I'm going to makeshift some kind of bracket between the lower mounting tabs and the chassis of the car, that prevents any swinging motion. Seems like that will be perfectly adequate.


There was a *perfect* little pocket for the water pump down on the driver's side of the bumper, and two holes through which I could zip-tie the pump very securely. It's not obvious from the pics, but there is plenty of room to get the water hoses between the radiator and the IC core.




Finally, I test fit the IC core in the engine bay. Pipe routing is: 90 degree aluminum bend off the turbo, t-pipe for the BPV hose, 90 degree silicone bend into the IC core, and 90 degree silicone bend off the core into the TB.




Next steps... route the water tubing, wire up the pump, and pray to god I can fit the bumper without too much hacking

Aye, that ye did. I copy/pasted that post from my thread at 247, so some of the more relevant details were bound to be left out.


Oh... and the bumper fits!

Well, mostly. Clearance around the entire radiator is perfect, except that the drain valve gets in the way of the lower passenger side bumper attachment point. A little work with a sharp box cutter should take care of that though.




Oh, and I found out that the bracket from the factory sub is almost perfect for supporting the IC core, with only a couple small modifications




Pic of the ghetto lower bracket I made for the radiator, using one of the mounting rails for adjustable shelving. Kinda ghetto but it will do ;)

Last time I bought it, I found it at Checker with the rest of the automotive chemicals. The checker near me closed though, so I'm not 100% sure where to find it. Pep Boys is probably a good bet.

Jay that's a really nice fit where the battery used to be. Excellent work, and thanks for the pics.

I've heard it can be tricky to find (except online of course).
Looks great Jay, can't wait to see how well it works!

The finished product...













To turn the pump, on and off, I wired a little rocker switch into the cig lighter, so that the pump is powered whenever the car is in ACC or ON, but I can switch it off if I want. Turns out, the unused battery harness that came with my HID kit was perfect for wiring up the pump (and fan when I get that figured out).


I'm too wiped out to take it for a drive right now, but I'll post up some driving impressions soon. Also, I'll be throwing it on the rollers next sat. I won't have true back to back dynos, but I will post up my charts from last fall (identical mods, except for stock intercooler) at stock boost and maybe 8psi. I'll also start looking for a good gizmo to do some charge air temp datalogging. Finally, I'm also going to start shopping for a nice slim 7" fan or two. The fan that came with my kit was just a little too thick to fit behind the radiator, and I really want to run a fan to prevent heatsoak of the water.

So my initial impressions are that off-boost throttle response is improved, giving a more connected feel during gentle driving. I haven't noticed quicker or earlier spool, but that doesn't surprise me too much given the how quickly and early the turbo already spooled, and how little boost I'm pushing. I took a trip down to rochester sunday, and used that for an opportunity to get a little better feel for how everything was working.

I did notice boost coming on a little more smoothly than with the stock setup--before I would get a surge of power around 3k rpms as I hit peak boost, which would back off a bit as I kept going. (This is backed up by dyno charts, which I'll post along with my new charts from this coming saturday) Now the boost comes on smoothly with no surge... so it feels like I'm getting less power at first, but it pulls much better through the higher rpms. I also noticed that from 4.5k rpms and up, the boost edges closer to 8psi, and my narrowband indicates that I'm running a bit leaner in the higher rpms. Now, I wouldn't trust that gauge for anything but gross changes in AFR, but I am fairly certain that my dynos will show me leaner up top than before. Hopefully not too lean... hehe

But my observations seem to support that I'm getting a cooler charge and lower pressure drop across the core that with the stock setup, so that makes me happy. I don't yet have anything to monitor charge air temps, but I'm looking at picking up an inexpensive dual thermocouple reader (like this) and a pair of fine-wire TCs to measure temps up and downstream of the core. I'm also considering a water temp gauge, but that seems less important.

My next update should include dynos, and hopefully some temperature measurements soon to follow.
