Um... You people are still talking about auto GT's being quicker than the auto GTS...
It's a joke that you still believe this wild rumour. and I'll go on record right now and put all my cards on the table... unless you are running forced induction of some sort, there is no way in hell an auto GT will beat a sportshift GTS. If you have an auto GT feel free to hit me up for a race anytime you want and I'll be sure to politely hand you your ass.
Manual GT with a decent driver, yes, that's totally conceivable if he's got some bolt ons, a manual GT will give the sportshift a good run, and if the driver is any good, he could probably squeak by you and win, but an auto GT, even if he's manually shifting the gearbox, he isn't gonna win.
and if the sportshift has mods too, look out.
Lift makes all the difference in the world, off the line the GT may have a slight edge because of the extra torque (maybe you'll get ahead by 1/2 a car length initially) but by the time my tach needle gets to 5K it's all over.
You can get some good gains from Intake
and exhaust work, and if you choose to spray on an auto GTS it would be sick. Pretty much any engine mod you can do to the manual GTS will work for the auto GTS as well (pulleys, valvetrain upgrades, lightened or knife-edged crank) You can also bump up the compression with the 13:1 pistons if you choose to, just be prepared to either run racing fuel or buy an ECU upgrade from brash boy to runn off pump gas (the only ones that currently make them for the GTS autos that I know of)
TBKO is still working on an ESK for the GTS automatic tranny, it will also be available for the GT though.
last bit of advice I can give is this: weight reduction is your friend. Carbon Fiber Hood
and Fiberglass or Carbon Fiber fenders can help in this regard (both Carbon Fiber and Fiberglass fenders are now available BTW)
True, nobody is hating, but then again, lots of people are still talking a bunch of
drivetrain loss is the same whether it's a GT or GTS auto, the difference is in the engine, the gt makes 140 HP while the GTS makes 180 HP and has a higher redline. Being able to manually shift (and downshift)without tearing up the tranny also helps things.
Don't buy into the haters, just turn a wrench and practice, practice, practice. If you're losing to a auto GT, you're doing something wrong.
