Anyone else had a new engine build run in on a dyno once fitted to the car ? ..im thinking of getting everything all in and then taking it up to my tuners for running in and mapping .

Mad_Mat

Ive just done this at MSD with my 3dr.
Ran in for an hour doing a simulation on the rollers to load and unload the motor.
Then did another oil & filter change with quality oil then on with mapping as usual.

It is a bit of personal preference though. I prefer the hard break in method.
Some people prefer a much longer run in break in period.

Mine was done on engine dyno after built in N/A guise 3hrs up and down revs, gave the builder and myself piece of mind, rather than spend all the time with installing to find an issue.

Mine will be run in as above. A good hour on the dyno with millers running in oil. Then changed for high end oil and kick it’s head in!

I'm liking the 1hr run in ..i always use msd so im going to let msd run the engine in and map .

slammedorion

Run it in hard
We did mine on road and did as my mapper requested

Does one simply remove the odometer or any part to remove adding on mileage to the car during these running in on the rollers?

As mentioned above a 3 hour run on the rollers could potentially add 200 miles onto the car. Its not like the car has done any 'miles'.

I've never unplugged the odometer whist on dyno or running in ..

I'll let MSD run it in as Stu see' s fit ..be good enough for me .

know a fair few that have had their engines done by MSD and all were happy

Yea I've spent all day reading about it all ..msd will have another to do soon ..safe way to do it all round by the sounds of it.

My 3hrs was on an engine dyno not rolling road

slammedorion

On the road is ok but 3rd gear plus pulls can start getting silly
Dyno is much safer for everyone/ everything

ajamesc

Surly a 3rd gear pull running it in would be like driving miss daisy

Rsmat

Try that when it's damp and your making the pulls in the 3dr cosworth with just over 400 ..you have to hang on ::

On a 400+ bhp car running it in and doing it on the road I was advised to not rev over 3000rpm and not load the engine on hills etc but it still relates to 90+mph which is a bit quicker than driving miss daisy A few long drives and it was soon run in!
The modern way of getting your tuner to run it in will suit a lot of people better without a doubt.

ajamesc

I build a fair few big Diesel engines at work and they don’t get ran in lol. First start it’s left running on fast idle so not to glaze the bores. Once all’s ok no leaks knocks or anything amiss it’s straight out driven as normal.
Things are lot more reserved with cars lol. When mine getting ran in I’ll just follow the instructions of my engine builder

Caddyshack

When my air cooled 911 was blue printed the builder said to drive with wide open throttle and big loading but not to rev over 4000 rpm...don't know if that is just air cooled but doubt it as ultimately all cars are air cooled one way or another.

The AMG factory is lit from power generated by the hand built engines being run in on the dyno....I love that concept.

That's just mad ..but love shit like that ..fair play to them.

Does anyone else thinking mapping cars is impressive and interesting??

Rsmat

iTrader: (2)

It's all fasinating stuff mate.

ajamesc

Along with choosing the right spec for what your trying to achieve mapping has to be the most important part of engine tuning

Rsmat

iTrader: (2)

Bang on its about getting it all right ..do that and you create a lovely driven engine .

unplug the speedo from the gearbox end whilst running in then connect it back after

Hi Glenn, its also loud and scary when your car is on the rollers!! I had to go outside as I was thinking "hope to fuck it stays in one bit". Relief when its finally finished and then the buzz of the drive home with all the extra power!!!!

Course its done miles, wheel are moving, engines running, transmission is in use.


Only thing that's not seen the mileage is probably the brakes.

Rsmat

iTrader: (2)

Why would ya ..?

Loomer

Its a good way to do it really as many things can be monitored, just the cost side of things i guess puts many off as paying per hour on the dyno is expensive compared to just sitting in the car up the road.

Ive got a few ready to come for running in and shakedown when mine is ready to use.

ajamesc

Mine was mapped on the road in real world conditions

Rsmat

Those days are gone now my tuner as one of if not the best dynos in the UK .

ajamesc

I guess you can only take the advise of the person you use I use one of the best mappers in the business. I think there basically set up on a dyno but fully mapped on the road/somewhere suitable if possible

Rsmat

iTrader: (2)

I just take my car and leave it with them ..then wait for the grin on the way home ..its been like that for 15years .

RSmark84

Re-read my post and you'll see 'miles' at the end, AKA actual road use.

Saying engine is running isn't something you can use as an excuse as engines run without moving.

cossynut2

I guess if you own a car that is really just an expensive toy and never gets driven then 200 extra miles are important!!! Why bother having it if you are so worried about a few hundred extra miles going on it.Sorry I just dont get it!! Cars are to be driven and enjoyed IMO.

Rsmat

iTrader: (2)

My escort is low mileage but I will not be unplugging the odometer ..as the car is still doing the mileage on a set of rollers just the same as it does on the road .

turbotrev

That’s what I thought ha ha

Cheers Paul

turbotrev

I disagree.

Mapping in real world situations is a lot better if it can be done

A dyno can only replicate that environment as best as possible...

Cheers Paul

You're not making sense ..no where have i said a dyno is better than open road mapping ..my tuner stopped doing open road mapping and now does dyno mapping on one of the best dynos if not the best in the UK I never said it was better than open road mapping .

Jay,

iTrader: (4)

yep a good tuner will do most on a dyno and the final tune on a road in real terms .

As for runing in I've always used 100 miles on old multigrade oil with 8psi up to 4500rpm then some proper oil and more boost more revs for another 100 then full map then let it av it lol

Rsmat

iTrader: (2)

I'm not entirely sure what Stu does mapping wise these days as things have changed since I last used him ..but people have said running in is mineral oil for circa 100 miles ..dropped and some proper oil in and boost .
