I've been getting my car updated to do some more serious road racing. Last time I went out my oil temp got up to 275 after 3 hard laps (and they weren't even that hard based on my track times). I've been reading Matt Robertsons posts over on LXF about his mods and based on that decided to go ahead with a few mods to help me get around the track better and put as much wear on the car. Some of these mods you already know about.

These should help me get around the turns better, but what I hadn't done is beef up the cooling systems. I ordered the parts based on Matt's list and then set up a time to get them installed. I have a buddy that owns a custom shop that does all kinds of work and we agreed to do this in the evening. The first night we were there until 2AM working on the car and the next night we put in about another 4 hours.

Ok on to the pictures. Here are the boxes from summit. These contain all the fittings, coolers, fluid, and hoses.

This box contains the oil cooler and a few BT pieces that you've already seen.

A few things that I learned. The little cooler on the front of the SRT is for the power steering. The tranny cooler is behind it on top and the A/C condenser is below it. Behind all of that is the engine radiator. Initially I was going to do auxiliary coolers for the oil, tranny, and power steering. However since I have a good size power steering cooler I elected to not install the one I bought. This also meant i didn't have to fab up some mounting tabs and relocate my horns. I know some have had issues with the power steering pump going out even on the SRT but that was under some hard steering like doing drifting and autocross. If things look bad I'll go back and install it.

the first thing was the tranny cooler. This wasn't too bad. We made some mounting brackets and attached them to the cooler with some 5/16" all thread and then bolted the brackets to the front bumper rail.

We came off the top tranny fluid line from the stock cooler and went into the aux cooler and then back into the line we cut. the connections for the stock tranny cooler are a special connection that has a little retainer clip so it's important not to lose it. We did have to bend the metal hose so that it could fit with the fascia on. That sucker is tough and last thing we wanted to do was kink the hose.

Next was the oil cooler. This wasn't too bad but there are some things to be aware of if you're doing this on the SRT and maybe on other 300s as well. I used the mopar police oil kit and followed the install how to by rjkusse on LXF. The oil filer nipple has to be taken out and the only way to do it is get on it with a pair of vise grips, you're not going to need it anyways. After we got the cooler unit on we tried to put the filter on. I got the same filter that is recommend M1-204 (Mobil 1) and that sucker wouldn't fit. The nipple on the oil cooler is bigger. After some searching we found that I needed a magnum filter, M1-210. The other thing is that the lower radiator hose replacement is a different size than the stock one on the drivers side connection. It should be a 1.65" ID but it was a 1.44" it doesn't sound like much but when you look at them you can tell. We ended up using some heat and a pair of pliers to stretch it out enough that we could get it on. Its tough but do-able.

The last thing we did was install some steel brake lines that I got from BMC.

I had a small leak at a fitting on the tranny cooler but a few turns of the wrench and it was fixed. I've been monitoring my oil temp and I know that driving at 70 on the highway the temp was around 220-225 and now i run 206-212 depending on the outside temp.

Sorry I don't have more pictures but we were moving pretty fast and didn't have much time for pictures. Last thing on the list is some new tires. I got a spare set of SRT wheels from Meech, just need to put some rubber on them.

I installed the power steering cooler today. This one mounts just below the hood latch and requires the relocation of the horns. I chose a cooler that had the fittings on one end as opposed to one on each end. I bought an elbow so I could turn one of the fittings down to make an easier connection. I also found out the barbs included in the kit don't seal so i went to NAPA and got some brass ones with longer threads. Some brackets were fabed up and attached to the support for the top of the fascia. I was worried it wouldn't be strong enough but that sucker is on good and should hold just fine. For the horn relocation I've seen where some people move them to the front bumper support but I found out that by modifying the horn bracket they could go back almost in the same spot.
