Oil cooler temp difference
Hi all,
Just thought this tidbit of info would be interesting.. When I finished putting my new engine in I didn't have my new oil cooler yet, and of course couldn't use the old one because the old engine imploded with metal bits all over the place in the oil system. So what I did was bypass the old cooler (cut the old pipes, cleaned them, and looped them back). The car ran perfect like this and at idle the temp was the norm - around 190-200deg on the gauge (just before the middle). However, driving on the freeway, not exceeding 4Krpm, the temp would creep up to around 230deg. Still well within operating spec (170 to 250 is normal operating range), but definitely higher than normal. Tonight I got the new oil cooler on (my own custom design - not OEM), and now the temp never exceeds 210, actually sitting right around 200 under load. So the interesting info - the oil cooler keeps the engine 30 degrees cooler just at normal freeway speeds! I wouldnt have thought the cooler would have made such a large difference during normal driving, but it shows that the coolant system on this engine barely keeps the engine in operating range without the additional cooling. Anyway, just thought that was interesting.. Thanks! S. |

Beyond that I'd probably look at a more efficient radiator. CSF has a bunch of upgrades to the cooling elements (radiator, oil, transmission, power steering) to improve cooling quite a bit. I haven't upgraded my radiator yet but will likely be doing so soon. Thanks! S. |

The interesting bit was how much it is required during light usage. When driven hard, street or track, of course oil cooling is massively beneficial. But to affect temperatures by >15% just while cruising in top gear shows how important it is on this particular car, and thus also why upgrading it could be useful.. Thanks! S. |

anyways, what are you doing to address the way the cooler butts up to the exit vent on the undertray? custom rear shroud?
