1st place DSP: 2nd at 2007 ProSolo DSP (4th at Nats)
2nd place DSP: 2x DSP National Champ
(Both of the above have a newly rebuilt motor with what seems to be significantly more power)
3rd place DSP: 1st at 2007 ProSolo STS
(To be fair, I'm still at 7psi boost, eyeballed alignment, and on on 200 run Kumhos while everyone in DSP runs fresher Hoosiers :P)
How effective are things like header wrap at keeping temps down? Is it just a waste of time?
Header wrap will keep the bay temps down.... but I doubt they'd have a serious affect on water temps.
- What fans are you running?
- What T-stat are you running?
Those are pretty much the only things you can change on a DSP car for cooling. I'm assuming you've already bled coolant numerous times, and checked that the water pump belt isn't skipping (I had that problem once... luckily the belt didn't shred completely untill the finish!). If you can take the belt off, check that the pulley isn't wobbling, either (pump could be going bad?).
I don't have an after market temp gauge but I have noticed a difference when using Redline water wetter. Living in Hawaii, I don't worry too much about water freezing.
Currently have a bottle of Redline Water Wetter, Bottle of Prestone Cooling System Treatment and straight water. I wish I could give you actual temps but normal operating temps does not go past the 3rd notch on the stock temp gauge.
So what's the best place to put your aftermarket water temp sensor? I have mine at the upper radiator hose, but the reading seems to be off as it reads 150 F when the stock guage reads normal.....
My autometer sender is in the upper hose as well. When the autometer just starts to register temp (100ish*), the dummy gauge goes to the middle. It stays at the middle until ~220*+. Almost entirely useless.
It seems that the stock KA (at least the 1995) has 2 coolant temp sensors: 1 for the gauge, and 1 for the ECU. The ECU sensor is a 2-wire unit, and the gauge sender is a 1-wire unit next to it. Is there anyway to replace the stock sender, or tap into the ECU's sender? I was planning on just swapping out the stock sender for an aftermarket one, and plopping a new gauge into the cluster (plopping = cutting, fitting, molding).
JohnGriff on zilvia (RPSport.com) is making a digi gauge that will fit in the stock gauge location and read the stock sensor. It'll have a warning LED also. He's trying to keep in under $90. This was the thread, but he deleted pics (it was a rough mockup) http://www.zilvia.net/f/showthread.php?t=186428&page=3
