I have an additional front mounted oil cooler and have observed high temps on track after multiple laps, I know other's with the D5 cooler who don't even have to think about oil temps! I have to watch them!!

Outside the operating range for the oil?
On a hot day with prolonged hard use I see my oil warning light flash on my oil temp gauge!
But you have the one attached to the back of the sump which is the one to have! If your not using the D5 one then I would imagine its not a problem for you to fit it!
Cheers Greg
The info I went on, is the data logging and testing on track that Ashok and Tim Williams carried out on Ashoks S60R. I can't remember the precise figures, but there was about a 15/20 degree (IIRC) reduction in peak oil temps after fitting the D5 oil cooler. What ever the peak oil temperature was (125ish degrees I think), it wouldn't go any higher, even after half an hour on track.
Well if a few bods have tried it & it seems to keep things a bit more stable then I feel the risks on not fitting it outweigh the risks of fitting it.
Good news today is the turbo is back with a clean bill of health. Bad news is there may be an issue getting 1 conrod so I may have to fork out for a complete set.
I still have this nagging doubt that early ME7 (just like geartronic) is not the way forward. But alternative manual throttle C70s are all one colour these days (and I know I'll get flamed for saying so) but G/G is just wrong.
will those rods fit a t4. least youll get some of your hard earned back
i think a new project entirely will get you more motivated dave, join the 850 crew :wave23d:
I was worried about my S60R 2.5 engine splitting liners so two years ago I obtained a low mileage 2.4T5 engine. Tim Williams built it to my specs at the time. Forged rods using the standard pistons. Ported the head. Shimmed the liners. I also have a FMIC. Farita down pipe with cat back. And progressive water injection. Tim used the original oil pump because of the high failure rate of the new Volvo pumps. I am still running the k24 that has been on he car from day one which has covered 108,000 miles. I have a mte custom map and running 1.5 bar boost. 366.6 bhp which is the maximum that my turbo can put out. I have done about 20,000 miles since this engine was installed. Seven track days and I have had no problems at all with it. What I have posted above is not ment to come across as any type of bragging, it is to inform you how strong and reliable the 2.4 T5 engine is.
You are not many miles away from me so if you want we can meet up and show you
I would suggest that you couldn't go far wrong if you did something similar with yours
Another point to make about Dave's post, is the spec he's running, is the same spec as me(apart from the Owens 19t), Ashok, Gaz, and others. The main point being that it's a tried and tested method, that works consistantely well on the road and track. And for a solid, safe and useable 350+bhp it's perfect.
But I understand that you are going a step beyond that with the GTX30 and aiming for higher power 400+bhp, that opens a whole new can of worms in almost every aspect, as you're aware. But it has been done on several cars on T5D5, even on ME7's. I wish I could be of more use to you Dave, but I just give the car to Tim, and he works his magic, 80% of it goes right over my head! I hope you get everything sorted Dave, and you end up with what you're after. I wouldn't be afraid of joining up on T5D5, the knowledge between a few key guys on there really would be of great help to you I'm sure.
Hi Cris. I am happy with my car ATM but the next thing for more power is to change the turbo and get it mapped for that. I haven't decided what route I am going for yet. I am watching Dream3r's idea of a 20g. When are you putting yours on a rolling road so I can see the improvement with the Owens 19t hybrid?
I chose the GTX because it was newer than the GT series and seemed to provide a good bandwidth to play with over what I believed to be better at the time than the 19T.
It doesn't have magic powers, despite what Frankie might believe - and it's been PITA to fit. The GTX does not give me guarenteed HP.
The engine development grew from the mess I got myself in when trying to take of the head of the donor engine.
The cylinder head specialists reworked the head onces they'd got the bolts out, that I rounded. The engine rebuild grew from that.
I probably should have moved to a more specialist firm & spent more time getting the engine just so.
Yeah but the turbo isn't controlled by the map. But regardless - just a quick note to add that I only lost a small amount of skin getting the engine out from under the car. So far I've split the gearbox off, removed pretty much everything (still got the clutch/flywheel to do). I've already ordered the ARD lighter crank pulley & the plasticy inlet manifold spacer from snabb.
I need to retrieve the crank from my old engine & look at both oil pumps - see which is best & then start the deep cleaning process of my block and sump.
I tell you what though - the snap-on gun I bought from ebay - may not undo the very tightest nuts but it does do most & has made things 10 times easier, given I don't have access to air tools this time.
I've bagged & tagged as I've gone along - hopefully I can remember where it all goes. So I am getting there - slowly.
I am toying with the idea of the TTV - I am using a Volvo OEM DMF, because I was advised that it would be kinder to the driver train. Could it potentially harm it & does it make it more difficult to idle & does it cause more stalls?
BT's TTV is still sat on the shelve in the garage till i'm ready to swop the gearbox so no direct experience, i do know there are a few people using them now & made a noticable difference to the rpm pick-up. These have been 850's tho so already fitted with a SMF
Graeme is running a TTV iirc.
toe-less graeme or captain slow?
Toeless Graeme (not slow Graham)
