I was wondering how much hp would warrant the purchase of these or would I be fine with just the regular ones. I'm more concerned with reliability and really don't wanna be pulling stuff apart for a long time after I have them in. Obviously I want it for an n/a application with probably no more than 200 whp.



TIA

 

It is not a BHP thing, they have better oiling and quality. Spend the $30.00 dollars.

 

How many miles are you planning (hoping) to get out of the motor. The race bearings will give you a much looser clearence that will sacrifice some longetivity.

If this is a mild build that you want to last 70,000+ miles I would use the standard.

If this is a street/strip build definately use the race bearings.

have you ever used the acl race bearings? how do you know the clearence will be different?

 

i've never dealt with ACL before.. but i was wondering if they are color coded like honda, or do you have to clearance your motor first with your old bearings, then tell them whaqt sizes you need?
i sure hope they aren't a "one size fits all" application like napa bearings.

also, why would these be any better than oem? especially when you open up the holes on the oem ones and deburr the edges? what would be the major advantage to using ACL bearings?

I have not used the ACL race bearings but I have seen them. They don't have a coating on them like ACl standards do. Thus they are thinner and will provide you with a looser clearence. I imagine they are similar to Honda Pinks.

huh? looser clearances? you must machine the engine components to achieve the clearances that you are building for. you dont let the bearings tell you what clearance your gonna have, you do that your self. and you dont need a whole lot of different colors like honda has from the factory to achieve the clearances you want. although that makes it easier, but less fun. but none the less the engine builder will machine the components to make the clearances what he or she wants, all you need is three different size's of bearings ( standard, .001+,and .001-)and some machines or in most of your cases and good machinist and your good to go.

Listen to this guy I agree 100%

Don't give me colors Give me numbers

 

The colors translate into numbers with Honda bearings...so I don't see the point with you arguement in respect to these. As far as I know though ACL's only come in one size other than the -.001 size for the race bearings. Also, if you have OEM bearings available to you and can size to each individual main and rod then why would you want to machine your crank? I would think this would cost much more and have much more room for error. And how does sending your crank to a machine shop to get it machined make the engine build any more "enjoyable"? And what if one of you mains or rods is already below your +.001 bearing? Do you just throw it out or do you go buy a Honda bearing that will fit it and keep the crank? I personally don't have the expendable funds that a race team does so I know what my $5 choice is. I'm very interested in hearing why you both say machine the crank however.

I think I will listen to myself and neogenesis2004. Why waste time machining when you can use a bearing to get the exact clearence you want. ACL race bearings are exactly what they are. A race part. They are thinner and will create looser clearences in your motor. It is that simple.

 

ACL's standards are green..

they jsut remove a flash coating on the new race bearings, which makes them look like crap, but who cares what they look like.

i assume the flash coating that IS NOT on them woudl be a very small difference in size com[pared to the regular acl's but i have not clearenced them yet.

ill try to get some #'s, or don might be able to, of the OEM green Vs ACL standard Vs ACL race thickness, so we can get some definite numbers

First off, who said anything about machining the crank?

Second if ACLs like you say only come in one size for a race bearing then thats pretty laim. Probably why 99% of the industry stick with Clevite H bearings or Federal Mogul. Anyhow most production motors come with as little as .0005-.0007 on the mains and .0022 on rods. You usually want to go with .001 of clearance for every inch of shaft diameter. For race applications add .0005 to total clearance. As parts become stronger clearances become tighter.
