Balancing a Motor what do you guys think
 

i am in the process of building a b18a block
with eagle rods, srp pistons and a 8lbs flywheel

and i was wondering what you guys think, should i get it balanced or not?

i plan to rev to 7500 at most maybe 8000 down the road, i just want to do it right the first time
i have the head to support the motor


thanks

Balancing a motor is always best. Worth the extra money.

Re: Balancing a Motor what do you guys think
 

BALANCE>>>>>> YES

Re: Balancing a Motor what do you guys think
 

Most guys on here dont ballance their ----, if youre not in professional racing and getting up to the 8-9-10K RPM mark then I dont think its neccesary, It is a good idea and would do good for the engine but what is the point if you could put that money somewhere else.

Re: Balancing a Motor what do you guys think
 

with the 8lb flywheel, you definitely need to get it balanced. Any off imbalance in the engine can be felt more with a light flywheel.
Speaking from experience....

If you are putting money in the rods and pistons.... got the extra inch to get the thing balanced. It does make a noticeable difference. The engines that are balanced tend to run cooler, have quicker throttle response... and most importantly last LONGER.

Would you spend 2k on racing rims and tires, and NOT balance them? They might not vibrate too much, until you get over 60mph... but the tires will wear sooner.

dew it....

i would def do it. no point to build the motor and skip steps

Re: Balancing a Motor what do you guys think
 

then i will spend the extra 140

Re: Balancing a Motor what do you guys think
 

I just micro polish the crank and good to go, but if you can afford it do it.

Re: Balancing a Motor what do you guys think
 

i never have.........





p.s. on the 2 i rebuilt lol

Re: Balancing a Motor what do you guys think
 

i did it, unbalanced parts dont like to spin to well. just think about what happenes when a turbo is unbalanced and breaks

Re: Balancing a Motor what do you guys think
 

Def do it. Especially if your gonna rev to 8k or so.
p.s. are you gonna balance the crank and all that too.

Re: Balancing a Motor what do you guys think
 

If your balancing the new internals, they need the entire rotating assembly... that means crank, pulley and all that good stuff. I would do it just for the peace of mind. From factory Eagle's rods and normally a high quality after market piston (like the ones mentioned) come from factory very close to being in spec's for balancing. It's a good idea just to have them balanced and check to make 100% sure nothing is out of whack due to shipping or a possible slipup from Eagle or JE.
I've heard people's claims that if it's not a race engine, then it's not worth the extra cash. That is true to a point, however wouldn't you feel safer knowing your engine will last longer and all is within specs.? You can never be too safe. :D

It might be ok or it might not, if your doing it right balance it. Your bearings will thank you.

Re: Balancing a Motor what do you guys think
 

about how much should someone pay to have a the entire rotating assembly balanced ..along with crank pulley and flywheel?

Re: Balancing a Motor what do you guys think
 

about 100-150. The best thing to do is call around of course. Ask them how they balance them too. Putting crap on a scale and calling it a day is definitely not the way to go. You should also ask for the specs on the parts... just in case you have to replace the balancer/flywheel ect later.

When My engine was balanced, I told them to "zero" balance (stand alone balance) the balancer and flywheel. If I ever had to replace them, I would just need to get them balanced before I put them on.

Otherwise, if they are using your balancer to even out your crank and pistons, replacing it would require rebalancing the entire assembly... otherwise you would have an out of balance set up again.
