Gavn Posted 29October, 2017 Report Share Posted 29October, 2017 I'm trying to decide between either a front mount or 'in guard' type of oil radiator to swap out for the current factory trombone type cooler in a '78SC. The engine is close to stock and the factory trombone system works well enough for road use but I'd like to get the temps down a little on track days during the warmer months. So the cooling I'm looking at would be at speed (i.e. sitting in traffic is not a concern). The current front bumper setup has room for a front mount cooler. Naturally there's also room in the guard for the later 3.2 type cooler to replace the trombone.What are the pros & cons of these two options for track work? I'm leaning towards front mount purely because the panel is there and I assume it's the more effective option...Edit...should also mention that next time the engine needs to come apart we'll likely go for a bit more horsepower...3.2 - 3.4 so part of the idea is to future proof the cooling side.

clutch-monkey Posted 29October, 2017 Report Share Posted 29October, 2017 takes me a bit longer for the engine to get up to temp with the front mount, but it is very stable on the track. if the panel is there, fill it in with a front mount oil cooler.

Teutonic Posted 29October, 2017 Report Share Posted 29October, 2017 Relevant to my interests. I am running twin coolers in the guards and reckon the car could run cooler. Gets to 120 deg on track. Link to comment Share on other sites More sharing options...
Gavn Posted 30October, 2017 Author Report Share Posted 30October, 2017 We're also touching 120 on the hot days at Wakefield Park - I'd be happy to bring it down 10 degrees or so. Teutonic - are you running a factory 3.6 or something more exotic? Link to comment Share on other sites More sharing options...

Teutonic Posted 30October, 2017 Report Share Posted 30October, 2017 Gavin, a little more exotic. 3.8. Thinking about ditching one of my guard coolers, keeping the first one in line and mounting a larger one in the middle of the bar. Link to comment Share on other sites More sharing options...
tk111 Posted 30October, 2017 Report Share Posted 30October, 2017 Gavin,I changed my trombone to a radiator in the guard. SC engine (slightly worked).I used to get a bit warm on Wakefield day’s, as soon as I switched to radiator in guard temps got all sorted, just past halfway after pushing hard.I don’t really drive in traffic, so didn’t bother with the thermostat controlled fan or the air blockouts around the radiator.

Thinking about ditching one of my guard coolers, keeping the first one in line and mounting a larger one in the middle of the bar. thats what i did with the white car, however on the orange car which is a bit more worked i had to keep the other fender coolers as well! could be down to airflow though- the DP front lip is a larger aperture. Going big... big but should fit in standard iroc/rsr front aperture as per aboveon the more worked longhood had to keep both fender coolers and the smaller central cooler Link to comment Share on other sites More sharing options...
Teutonic Posted 30October, 2017 Report Share Posted 30October, 2017 Good to know. Might go down a similar path. If it's worth doing, it's worth over doing !! Few $$ in the engine now so would like it to last. Link to comment Share on other sites More sharing options...

Teutonic Posted 1November, 2017 Report Share Posted 1November, 2017 Thanks for kicking this thread off. It has finally spurred me into action. Looking to grab a setrab extra wide (405mm wide) 15 row cooler and use it to fill the front aperture in the 964 bar and run it in series to supplement the twin coolers in each guard.

LeeM Posted 1November, 2017 Report Share Posted 1November, 2017 Being a numpty, would a few big coolers take longer to get up to correct operating temperature during the cooler weather? Link to comment Share on other sites More sharing options...
clutch-monkey Posted 1November, 2017 Report Share Posted 1November, 2017 Being a numpty, would a few big coolers take longer to get up to correct operating temperature during the cooler weather? yup. Not really an issue in qld for me though. It's never that cold that I can't get it up to temperature after 15-20min driving Link to comment Share on other sites More sharing options...
Teutonic Posted 1November, 2017 Report Share Posted 1November, 2017 ^^^ similar here in WA. You will have slightly more oil volume but that isn't a bad thing either. Cold engine doesn't bother me too much. Just keep the revs low and drive with sympathy until it's up to temp. Link to comment Share on other sites More sharing options...

Just keep the revs low and drive with sympathy until it's up to temp. pretty much, and takes about the same for the 915 to warm up as well anyway, what with cooler on the side of the 915 to keep it from grenading etc Link to comment Share on other sites More sharing options...
LeeM Posted 1November, 2017 Report Share Posted 1November, 2017 I only ask, and maybe it's a bit different, but when I raced bikes, the team fitted a bigger cooler because it was noticeably overheating after 2 or 3 laps (a modded engine with 180hp), but we had to tape up the cooler for morning practise just to get it up to op temp. The engine felt very flat at 60 degrees then kinda woke up at 78 degrees. Was told you can cold seize an engine by running it hard at low oil temp, but I've no idea if that's true or not Link to comment Share on other sites More sharing options...

Zelrik911 Posted 1November, 2017 Report Share Posted 1November, 2017 Think about getting one (in the guard) with a fan, for traffic.For front there are a few long non P. car radiators that work. A mate had a Jag XJ12 one (I think), ultra cheap but worked well. I think there is a Mazda one too? Link to comment Share on other sites More sharing options...
clutch-monkey Posted 1November, 2017 Report Share Posted 1November, 2017 rx7 oil cooler has small fittings. could potentially be a restriction, don't know if anyone has ever had issues though. Link to comment Share on other sites More sharing options...
