QUOTE(Vacca Rabite @ May 24 2015, 03:54 PM)  Dual SETRAB unit DOES fit in the same location that you want to put yours. Proof: (IMG:http://www.914world.com/bbs2/uploads_offsite/farm5.staticflickr.com-1435-1432508090.1.jpg) In this pic I have headers, but they also fit just fine here with SSI heat exchangers and a muffler. Also keeps oil temps low. Mine went from ~240 to 205. Mine is themostat controlled, with the stat opening and the fans turning on at 180. Zach Those fans do a good job of restricting the volume of cooling air through the coolers. Take them out or at least snip off the ends of the tie wraps. (IMG:style_emoticons/default/happy11.gif) |

In referance to posts #18 and #19:
Yes that is a cross flow cooler as are most of the other ones mentioned in this thread. That design is a stacked plate cooler having been sold under Long Mfg, Borg Warner and other manufacturers names. Not really better. They lack fins and are air side limited on heat dissipation. How many radiators have you seen made after 1930 that did not have fins? They do not flow air well. Long Mfg used to have the BTU heat rejection listed on their website showing this style cooler clearly removes less heat that a similar plate and fin cooler. The design dates back to WWII where it was used as an aircraft cooler ( P-38 ?) with very high air speed and fins could get flattened. They also need to be rubber mounted to prevent vibration damage. Ford used them as power steering coolers on diesel trucks with a high failure rate. Not a good choice for an under body cooler in the hot & poor airflow area under a 914 trunk. Regardless of what cooler you use an oil temp gauge will tell you if you have enough cooler. Bruce |

Well... It was pretty warm today... 80 degrees out. Oil temp got up to 270!!! Found out when I got home that I forgot to hook up the gnd wire for the fan!! Pretty sure fans work better when they are hooked up to power correctly.

Pretty sure fans work better when they are hooked up to power correctly. (IMG:style_emoticons/default/new_shocked.gif) on saturday here it was between 85 early and 95 later, and my 2.0 was pushing 235 and i was concerned about that. I am using Valvoline VR1, now, but otherwise the Gibbs oil Jake recommends and so i would immagine that it is formulated for temps like that - anyway ive been considering doing one of thse set ups as well to try and get those temps a bit lower, because that was just flat land driving. and ive been told that 220 would be a better running temp to hold under performance driving. So my question is, what will a set up like this run cost wise? and can a novice like myself do the work?(i've done most everything on this car myself so far-thanks to the World) or am i better off taking over to the local shop?(Bob Woodman-experienced 911 performance and racing shop). thank, and sorry for the hijack... |

Pretty sure fans work better when they are hooked up to power correctly. That sounds REALLY hot for driving around town. I start getting nervous with anything above 250 oil temps and that is racing which is ~20 minutes of WOT. I got to 250 with a brand new engine rebuild on the track and no external oil coolers (stock cooler only). Then I plumbed in the front coolers (which also adds ~3 quarts extra) and cant get my temps UP TO 200 without driving hard. With my front oil coolers TAPED OVER, I havent seen oil temps get even UP TO 220 yet this year with full track time. |

Not the best pic, but the only one I have of my setup (taken from the PO's FS listing, but the setup hasn't changed).
Setrab oil cooler with a pair of 5" Spal puller fans. Fans are activated via a 180 degree thermostatic switch, and I've also got the Tangerine inline oil cooler bypass so nothing goes to the oil cooler until temps get up. The front of the cooler has a manifold with two inlets that attaches to the orange ducting. There's a NACA duct in the rocker feeding one of the inlets, and the other inlet is fed via fresh air from the engine grill. This setup is actually too good. I have to beat the shit out of the car to get oil temps over 200. Typical around town driving has me at 160-180. I actually need to figure out a way to get my oil temps higher! I've tried removing the ducting, so that the oil cooler is only fed by the air flowing under the car, but the impact was only minimal. And this is in 90+ degree NC summer weather. I've been thinking about getting rid of the fans. Attached image(s)

Cool setup, I was thinking of doing an NACA duct on my rockers to do something similar when I install my Setrab/Spall combination as well.
On a side-note, what exhaust/heat exchanger setup is that? Very nice. And I guess that the 2270 is tuned well to have those temps...good stuff. |

It's the Tangerine 1 5/8 header into an EVO II silencer. It sounds pretty amazing actually. That little box is the Tangerine heat exchanger. As far as tune, I'm still working out some bugs in the idle circuit of the Dells, but the temps on the 2270 are great. Low 300's on the CHT if I'm putzing around town, if I'm really gentle it doesn't even break 300. Unless I spend significant amounts of time driving in anger, it doesn't ever approach 400. I'm just worried my oil temps are too low, so that I'm not getting proper lubrication in the engine. |

On the race cars, we used Duct (duck) tape to cover portions of the cooler to get temps up when we needed. |

I'm not currently seeing it on their website, (maybe it's NLA?) but they do have sizes that are close. http://www.elephantracing.com/oilhandling/...aboilcooler.htm |

how are you tapping the new oil lines to the new cooler in to the old?
