What lsa? Iv been in some ls1's with very similar cams on 114lsa's and one was later supercharged and one will be soon. From what everyone says 114-116lsa will be best, I think Kingston has a 112 cam s/c but I think from talking to him was going to a wider lsa down the track. Seen some results of 113lsa cams decent sized making good power and times with turbos and no problems. Sorry for the ramble on there.
