LS1 balancer/Pulley

[shawnc16]

Anyone here using an aftermarket balancer/pulley on their LS engine? I have a stock F body pulley thats junk, cant use it. I'm looking to spin the engine to 7000+ possibly and I know for a fact that OEM balancers come apart at those RPMS anyway. Looking to see what people are using.

Well I'm running a ATI balencer on my LT1 I'M spinning 7000 RPM they have pretty much the best balencer out there I've seen a lot of LS1s with them as well .

Stock, 6900 limiter. If you get an aftermarket get an actual balancer, not just crank pulley, real balancers have some ability to absorb shock and harmonics, not just a nice looking pulley.

summit racing also has one with there name on it. its affordable and i have heard it a good piece, but have not try'd it myself. the power bond worked well with mine. Remember one thing alot of people buy them and just slap them on. a harmonic balance is suppost to be balanced with your rotating assembly. this includeds (crank/rods/pistons/flexplate or flywheel/balancer/). if your going to build a seriouse motor better include fitted rod bearings and rings along with lower timing gear and oil pump drive, to get a spot on balance. alot of people who just throw a balancer on end up with vibration in higher rpm's which can crack or spin a bearing or even break your crank. how ever for durability id save and go with ATI. short cuts cost money.hope this helps.

The Summit piece is supposed to be a nice unit....haven't heard from any actual users though.

I tell ya a good balencer is worth the money spent I have a lot of money in my firehawk bottom end and so I just spent the money and got the best ATI my big block has an 1800 dollar Lunati pro series crank in it and I am for sure going with ATI . But if money is a problem I would find the best peice within your budget I have seen these summit balencers on cars at car shows and at the track also seen a built in a mag a wile back that ran it id do a little check to see who makes it if its a good company that should give you sum peice of mind but if your spinning high RPMs id g
o ATI my machinest builds race and street engines and he built an old school small Chevy than would spin 10,000 RPM all day and it had a ATI balencer there real nice peice .

That's because you're nuts Russ! Lol. After working in the dyne cells.. I don't wanna see what a pulley does to my car when it flies off at 7200. It does happen!

Dont know why anyone would want to save a buck with a balancer. ATI here.... Its cheaper than a lower end.
