Balancing (Yes or No?)
Turbo Mini Forums

We are just getting ready to put the vans engine back together.

However we are in two minds about whether we should have the rotating assembly balanced. (Crank, Fly, Clutch, Damper)

This is a budget build which we are hoping for about 140+ nana's from when set up. A typical rev limit of about 6k but perhaps stretching to 6.5k for the strip.

The question is do you think it is worth having the balancing done?

If something is worth doing, it's worth doing half of.

Are all the bits from the same engine?

Either way each bit will have been balanced at some point so should be fine for a road engine.

If you had the time and money then yes, but it's not critical for your needs.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

whats the cost of having it balanced?

imo if the flywheel and crank are from the same engine it shouldnt be far out

Built from 'spares' - preverto flywheel from one engine, rod's and pistons from another, crank from a third, timing gear from a 4th etc etc

Balancing is about £60 iirc.

for £60 its got to be worth doing suerly?

I think I'm leaning towards doing it.

We've been trying to work with the mantra 'do it once and do it right' as we've had two many projects getting in the way of our mini builds rescently.

I'd be annoyed if we'd put all the effort in to building it just to have the engine fail due to skimping on a £60 balance...

In all honesty I wanted to balance it anyway but wanted an opinion before forking out hard earned. Balancing it is then.

Just got to find time to get the assembly over the balancers.

have it ballanced john, as you have a miss match of parts

at that sort of cash i think you would regret it later if you didn't

Yep all the comments on this thread have decided it for us. For the sake of £57.50 including vat we may as well go for it!

After building a variety of engines with help from a mate - he came to rebuild his mum's std 1275 metro and chose to balance it. He reckoned it transformed the car and made it nice to drive!

I stand corrected. You should know

Picked the rotating assembly up last night, they said it was relativly OK for a standard crank. They've taken a fair bit of it, so it should be good now. Also, they've marked it all up so that we can get it back together the same way and keep the balance.

The firm's name is Engine Data Analysis. They where very friendly and helpfull and had a good chat with me. They mainly do Ford and Chevvy V8s, but will do things like balancing for most engines.

they just as you go into Xscape? on the right?

I know there is a race engine building place, they have extractors poking out towards the road.
