I spend a lot of time at the track and the '11 and '12 5.0 cars with tune, CAI, exhaust, gears and DR's (and average Joe driver) are low 12 to high 11 sec cars @ 115 to 120ish mph.....nice times but with the same mods I have ran a 10.56 @ 135. Upgrade my blower to a TVS and I'm going 9's just like Rebecca Starky. :
Your car is an exception. Most stock blower GT500's are not even close to 10's, let alone mid 10's @ 135. I feel I'm a pretty good driver and have only managed 11.2 @ 124. Way off your times and MPH. I don't have headers or a lower pulley, but I'm not grinding on my factory timing cover to change a fuggin lower!
I think what has happened with all the hype and unrealistic times the shop cars where putting up (huge money is at stake for all the big shops) alot of guys who can't drive a high HP car with a manual transmission are frustrated. There are a number of guys on this forum alone that are on there 3rd clutch. I'm still running my stock '07 without any TSB work done on it and over 300 passes. These same guys will order the 5.0 with an automatic, think they can throw on some bolt ons and run 10.70's all day long....lol...not going to happen. Don't get me wrong, I love the new 5.0 motor and it has huge potential but if you don't have the patience, skill or knowledge to get a GT500 down the track in less than 11sec. its not going to be any easier or cheaper in real world conditions with an average driver in an '11 or'12 GT.
This is probably more true. EVO, Lethal, etc....make it seem simple to get a GT500 to run 10's. It just isn't true. Many with Whipples/KB barely get into the 10's. It is a hard car to drive....heavy, bottom end torque, and a 6spd. For many the new 5.0 A6 is the way to go. Contrary to your opinion, all you need to run 10's in a 5.0 is a TVS swap/tune(VMP), and DR's. There is a guy in TN that has gone 10.7 with this swap with just that. A personal friend in Baton Rouge has gone 10.5's with TVS on 9psi, bigs/littles, and some exhaust. I have another friend with a '12 that has ordered the VMP TVS swap with the 9psi pulley. I expect him to run mid 10's come this fall/winter. Don't sell them short.
