I need to start monitoring my head temps......
I have an after market center console from Morph (excellent quality) that I want to mount the gauge in. I'm stuck choosing between a regular ol' VDO CHT gauge from CB performance or an Odyssey Series II CHT gauge from Dakota Digital. See it here The VDO is about half price and is pretty simple. The only thing I'm worried about is the gauge reading high or low when it's hot or cold outside. Plus that needle looks kind of hard to read. I looks like it goes by 50 degrees, how can you even tell if it's 350 or 400 or 375 or 385? The Dakota Digital unit is temperature compensating with a nice, easy to read digital display. It's also about doubt the price of a VDO. Anyone have experiences with either, and can tell me any thoughts, experiences? |

The only instruments that can be bought for less than 400.00 each that are temperature compensated come from Dakota Digital... Temperature compensation means a lot to head temp gauges as they are only totally accurate at 76F otherwise..
I just used these as back up instruments for the new R&D Dyno that I am building as we speak... Here ya go... I have 3,000 hours in this test cell and I'm not done yet! (IMG:http://images.thesamba.com/vw/gallery/pix/324511.jpg) (IMG:http://images.thesamba.com/vw/gallery/pix/324512.jpg)Westach has went down in quality recently and VDO turned to total shit in 2004... Today it was 40F on my way home from work, the Westach gauge in my 912E showed 350F, that means the actual head temp was 36 degrees less.... In the summer if it's 100F outside the head temp gauge will show 24F LESS than the actual temp... Unless you like adding and subtracting, buy a Dakota Digital, if you have 400 bucks buy a SPA like these that drive my datalogger...
