I know there are a lot of variables to consider, but where abouts would an SL600 be timewise in a 1/4 mile.

What kind of impact would a Renntech upgrade have on that time?

Thinking about doing the upgrade!!!!!

low 12's? maybe? Engine wise it sounds like it should haul some serious ... booty. But not sure how much the weigh would affect it.

EDIT: After googling some searches it appears the R230 SL600's pull in continous high 11's & low 12's.

See my sig for my post RennTech 1/4 mile times. My SL ran a best of 12.3@118 before the upgrade.
