Any idea how much they dyno to the wheels after some break-in?
The new GT500's look really sick; I wouldn't mind owning a stripped down one.

Probably in the mid to high 11s. I've seen ones with pulley changes get higher. I saw a 2008 on past time last night with a blower swap pull low 11s. Otherwise, stock.

I also saw 3 S197 GTs run between 14.1 and 14.8 in the quarter...

My stock NewEdge bests that. Someone needs a driver mod...

stock 2010 GT can run 13.5s easily.

I did it in my F-body in 1st. Loved starting races at 6k rpms or so. Just can't be an old man and decide to make a sandwich in between your shifts

That's a good way to lose a race IMO.

Nice power from the cam-only Vettes. I wish these Heavy-*** IRS Goats would trap that high with the same power levels. I haven't been to the track since the cam install, but I am hoping for 120-122.

I was at the dyno just about month to month and a half ago and there was one that had 1500 miles on the clock, bone stock, layed 470 to the ground

Btw, your c6 ls3 looks sexy and I can't wait to get one after college. That much power on a cam-only setup?

Trans Am w/ A4 and 3.73's, what are your trap speeds in the 1/4 mi and what gear are you in going through the lights, D or OD or 3rd or 4th and also what RPM's are you at as well?
Thanks,
MS

I have only been able to run her in the 1/8th mile on Sumitomos which do it no justice. We are talking like 2.4 60 fts with pre-staging... horrible. Lol if you want I can give you an update this spring when I go to Cedar Falls for 1/4 mile here in Iowa on some Mickey Thompson Et Street Radials.

Either way though, good running LS3. Makes me want to invest a bit more so I can be sure I can afford one right after college
