R32 GTSTT Posted August 4, 2004 Share Posted August 4, 2004 Just done a RB30 conversion, and are at the stage of running in my engine. Ive heard alot of ways to do this, but just wondering how other people would go about this?

Bl4cK32 Posted August 4, 2004 Share Posted August 4, 2004 Righto... I pick My RB31DET up in a few days and this is my plan : Change oil/filter 2-3 times first 5000kms Main thing is dont over rev for first 500 kms Put eng under moderate load (ie accelerate from 40 to 80 a few times) aviod prolonged idle first 100 kms first 1000kms use any "plain" non friction modified oil after that change to good oil.... Happy running in Link to comment https://www.sau.com.au/forums/topic/47964-running-in-a-engine/#findComment-966915 Share on other sites More sharing options...
Guest Moses Posted August 4, 2004 Share Posted August 4, 2004 I will be doing this very soon , have been told to keep revs low (less than 4k) but not to drive like a pu55y as you need to load it up to bed in properly. I wont have any boost below 4k so I guess I can just keep my foot down and drive normally. Will only take 1000k's using mineral oil first then semi-synthetic.

JH32 Posted August 4, 2004 Share Posted August 4, 2004 Also I've heard driving up hills in higher gears is a good idea to help bedding in of the rings, by putting load on the motor Link to comment https://www.sau.com.au/forums/topic/47964-running-in-a-engine/#findComment-966931 Share on other sites More sharing options...
R32 GTSTT Posted August 4, 2004 Author Share Posted August 4, 2004 Ive got a wolf3D v4, however its been tuning for my 2litre. Do you think i should put the stock computer back in to run it in, or get the wolf tuned to 3500rpm, and then later after its run in tune it properly. Or do you think the wolf at the moment will be fine for running in the moment?

I'm interested in this as my EMS is tuned for a 300hp RB20 using stock injectors. so i'm wondering how it will go when i start it up with 700cc injectors Link to comment https://www.sau.com.au/forums/topic/47964-running-in-a-engine/#findComment-967012 Share on other sites More sharing options...
Fitzpatrick Speed Works Posted August 4, 2004 Share Posted August 4, 2004 when you start it up with those bigger injectors id say it will hardly run and will be rich as a pig!!! IF it is tuned for 370cc injectors and running the power you say the injectors will be pulsing for a very long time to try and get the fuel through, when you put the bigger ones in the will flow twice as much but still be open for the same time equaling twice as much fuel!!!! Run them in hard to go hard i say my run in will be on the dyno to ramp ups then a full power run on low boost is my run in process!!!

Bass Junky Posted August 4, 2004 Share Posted August 4, 2004 Do a search as this has been discussed at length before. When running in an engine, its best to use high and varying load, but not hig revs. Load will bed the rings in nicely.

FATGTS-R Posted August 4, 2004 Share Posted August 4, 2004 I would assume the best way to get advice on running in your particular engine is to ask the person who actually built it! I am not versed in this subject but was told it is something to do with how "loose" it has been built. I would assume that is referring to clearances, so the builder would know best. But as mentioned above by others, varying load, no high rpm "free revving", no prolonged idling is a good guideline I guess. And obviously using non synthetic oils to begin with. Not too sure about pulling up hills in tall gears though, might be too much load? If it was my engine, for peace of mind I would have it done on a dyno. For the amount spent on an engine rebuild a few hundred bucks of dyno time is pittence. @ R32-GTSTT: I would reccomend using the standard ecu for the run in process.

Bl4cK32 Posted August 5, 2004 Share Posted August 5, 2004 My best advice would be to swap out all gear that you had, and replace with all std items...ie injectors, afm, etc...then run the std ecu. AFM should be able to keep correct fuelling then. Saying that mine is being started on a Power FC, then fuelling set up straight away....with a mild tunew for the run in...using all std parts. ie injectors, afm etc... If you dont have the std gear, make sure you get a tuner to start it and check the mixtures straight away...

krawler Posted August 5, 2004 Share Posted August 5, 2004 a quick note ... Not only big load, but avoid backing off in a hurry. Always slow to build the revs (full throttle, high load) then slow to bring em back down. Dont just jump off the accelerator. Krawlies Tips For Running In Engines. And hey, if it works on an E5 (possibly the worse engine ever made), its gonna work on an RB Link to comment https://www.sau.com.au/forums/topic/47964-running-in-a-engine/#findComment-968637 Share on other sites More sharing options...
krawler Posted August 5, 2004 Share Posted August 5, 2004 Oh and vary your revs too. If you are on the freeway, constantly change your throttle position. You dont want to hold a certain rpm and load for too long.

Would it be ok to drive it ~4km to the dyno workshop or not?

GTR-Ben Posted August 5, 2004 Share Posted August 5, 2004 I will be towing my car to the dyno and then getting it to run correctly.. With a custom engine and a New Computer.. it's never going to run right first time, and will only hurt it driving it around untuned. At least on the dyno you can monitor everything.

krawler Posted August 5, 2004 Share Posted August 5, 2004 Heres a slightly off topic query ... How long does it take to be run in on a dyno? I've heard claims of around 15 minutes to be properly bed in using the slow-power-on, slow-power-off method with a rise of 1k each time (ie: up to 1000rpm, back to idle... up to 2000rpm, back to idle...)

Bl4cK32 Posted August 5, 2004 Share Posted August 5, 2004 Well Joel is starting his with all the std gear ecu etc....i assume he wont be driving it too far till he gets it on the dyno to check out the mixtures, but it should be ok..... *Disclaimer*....only if you want to...lol Link to comment https://www.sau.com.au/forums/topic/47964-running-in-a-engine/#findComment-968742 Share on other sites More sharing options...

Skyrine-Dave Posted August 5, 2004 Share Posted August 5, 2004 what is done when it is run in on the dyno? chassis dyno or engine dyno? is a full power full boost run included? my dyno shop said they would just chuck the car on the dyno and start ramping it up tuning for full power straight away.. and they've had success at it... but i am VERY uncertain about that method. I'd prefer a nice run in scheme Link to comment https://www.sau.com.au/forums/topic/47964-running-in-a-engine/#findComment-968906 Share on other sites More sharing options...
R31Nismoid Posted August 5, 2004 Share Posted August 5, 2004 From what my car will be getting things new except for rods. Just load it up on the dyno, bed it in and drive away a happy customer No long running in times or anything like that This is what will be happening with my car, on advice from Ben@ Racepace, and there is little doubt he knows what he is doing when it comes to this stuff. Certainly take his advice when he gives it Link to comment https://www.sau.com.au/forums/topic/47964-running-in-a-engine/#findComment-969417 Share on other sites More sharing options...
