Well this is part of my solution
1/2" drill bit and lots of them

Added a SPAL 330 cfm 6.5" fan with temp controller to the oil cooler to help control oil temps and air flow through the cooler and fender liner.

I've been thinking about it. I'm curious to see how much your radiator lowers the coolant temps, as my car gets VERY hot with the downpipe crossing the front of the engine bay and being so close to the radiator.

During daily driving, some traffic with freeway with Texas 100+ heat I am in the very low 200 degree range. If I start to push it hard, redline every gear, it tops out around 215-220 and then about 3 minutes after I back off it is down to low 200 again.

I have the Seibon TS c.f. hood, and painted it to match. It has the same lines as the OEM hood, but with 6 vents. Noticeable heat temp improvement.

I'm not FI'ed but with my 24 row cooler i'm seeing about the same here in south Louisiana.

Oh, I was talking about water temps, but my oil temps with a 24 row cooler are about the same, closer to 220 more so.

You guys down in TX are definitely dealing with serious drought, but up in KS we're not much cooler haha. We did get some rain, but temps still hover around 100-103F.

Anybody else heatwrapped some components? I haven't fit it to my budget for this build.

I just want to double check to see if you guys already increased the fang vent by cutting out the extra plastic, and whether it had any improvements. For me, I think it does. I hardly touch 220F the past several weeks. Water temps look good. Fuel gauge... inaccurate as usual haha! Car is getting shipped out to Baker towards the end of the week, so they'll be doing some warranty work on the fuel sending unit.

We cut the fangs the day the SC was installed so no way to compare any real test results. As I never had an oil cooler on prior to my SC install.

How's your car coping with all this dry heat?

theDreamer · 07-25-2011, 05:24 PM

No idea, we do not have dry heat.

Car is fine, but the system does not like the heat in the afternoon or long traffic exposure. I have never had the car over heat or anything, but you can see all the temps get up in traffic.

DIGItonium · 07-25-2011, 05:29 PM

Haha... I didn't remember it being that humid, but there was one morning when my glasses fogged up after stepping out of the garage lol. Justin's car seem to be doing very well even with the A/C blasting. Definitely looking forward to getting force fed... are you going to drop by to check out my car?

No.

Definitely will be, have a summer class going on right now but I usually am able to stop by once a week, give the guys a hard time.

zzdudaka · 07-25-2011, 09:34 PM

Did this help at all?
Water temps never get to the middle dot even on a long trip. Never seen any issues there.
Oil however is another issue. with the gtm sc oil temps quickly get to 220 in the summer and running down the interstate at 80mph i am running at 235-240 on the oil. Seems high to me even especially with the 24 row setrab cooler.

Wonder if you could add some ventalation to the cowl where the wipers sit to help incoming air pass over the engine and over the car? Not that this would help the oil temps much.
