too early for a dyno???

[blaze]

hey all i just got my new motor back from a rebuild. it has only just rolled onto 100k's im getting it tuned by greenfoam, n would like to know if a dyno run would be too much on a new motor? i was gonna wait till i least rack up 1000+ks. would like to also know what the car has to rev at to get a dyno reading

[Kernal]

Mate... Its better to be safe that sorry. Wait till you get to whatever the recommended Ks are.

yeah true ill ask the dudes that built my engine whens a good time

[brockee]

hey mate what sorta work got done to it????

Wait till after your 1000k's run in oil change, that way the cam has had time to be run in and the engine has settled.

Most rebuilt engines perform best after 2000klms. some people say its fine after the rings been bedded but i'd prefer to wait a couple of thousand first

[betts]

I waited until 1500km's until I put mine on the dyno, best to be safe I reckon. You need to allow time for the cam to run in and at least until your first oil change to get rid of all the run in fluids and such. Speak to your engine builder, some people slap it on the dyno straight after the build and rev it to redline, but that just doesn't sit right in my head. What did you end up doing to the engine?

Go by what your engine builder says. I find a 30 minute drive can run in a motor quite well, varying load/rpm and what not (yes there is a little trick to it).

Everyone has different methods, some are just more idiot proof then others.

every motor a have ever had built incuding 355,383,400,202,ls1,rb30 i have always run them in on the dyno and never had any problems ,once the rings bed in its fine and a cam only takes 2 mins to run in,with piston rings there either going to bed in or not

ended up getting it rebuilt to the same specs and cam but wo with the dual plane manifold and 9x7 air cleaner out the bonnet woulda loved to stroke it but i livein a complex and there's no more room on the fridge for any more vehicle noise complaints. the point is after 5months she finally alive! hope to crack 300hp
