That time for that SV8 would be achievable with the slicks, diff change and tune which it has had. Dont underestimate the quick times the LS1's can do especially with a proper tune and on slicks. However, we aint talking about running slicks. Those mods done to the SV8 would come to over $1600 anyway and the fact it was running slicks makes comparing it pointless. We are talking about a Heavy Auto XR6T sedan running a 13.3 with only a unichip ($1600) in full street trim. Lets compare Apples with Apples not Apples with Oranges.
