What size will I end up after getting 510cc Silicone implants?

Thank you for the question. There is no accurate correlation between size of breast implant and cup size achieved.
Generally speaking, the best online advice I can give to ladies who are considering  breast augmentation surgery ( regarding breast implant size/profile selection) is:
1. Concentrate on choosing your plastic surgeon carefully.  Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you're looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals  with your plastic surgeon. This communication will be critical in determining  breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as  “natural” or "DD/E cup”  etc means different things to different people and therefore prove unhelpful.
 Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup  size may also be inaccurate.
 The use of computer imaging technology may also be very helpful during this communication process.
3.  Once you feel you have communicated your goals clearly,  allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals.  Again, in my practice, this decision is usually made during surgery.
I hope this (and the attached link) help.

Your question about estimating your cup size after a breast augmentation and lift is a really good one, and what we tell our patients is that it is really difficult to do so. What matters more I think is if you like to look, size and shape of the breasts after the procedure, and understanding that the bra size can vary depending on where you are fitted or the type of bra you choose.  If you feel a bit uncomfortable about the size, I would suggest chatting with your surgeon prior to surgery and perhaps resizing implants as well.  Hope that helps and good luck!

I agree your question is better addressed to your plastic surgeon.510 cc breast implants are quite large especially when done in conjunction with a breast lift.  Please be certain to ask your plastic surgeon if he or she feels that implants that large may compromise your breast lift result.Cup size of bras varies with manufacturer and retailer so your final size will depend upon the store or you by your bra.
