$200.00???
I disagree that a 200.00 pulley swap will allow the GT500 to run with a ZO6. That is being very optimistic to say the least.. And I disagree that the Cobra will be 3600 pounds.. Most sources I have seen indicate 3800 pounds..
Weighing at least 700 pounds more is a HUGE burden to overcome..
The GT500 would have to have about 100 more hp to the wheels than a ZO6 comes with from the factory, to make up for the weight.. ZO6's dyno around 450-460 rwhp.. That means you will need a 550+ rwhp Cobra to do it..
If the 475 rated hp gt500 somehow gets through the factory with 420-440 hp at the wheels, (which would be great
) That would still leave you with about another 100-120 hp on the table that you would need "find", to be with the ZO6's power to weight ratio..
That is not going to happen with a simple pulley swap..
You're going to need lots of help from the aftermarket (exhaust,intake, who knows what else) , and most of all, get friendly with a good tuner and his dyno.. Doing this will of course throw your warranty out the window, and most likely sacrifice some of the factory refinement.
Theres more to a fast car than just HP.. Weight plays a huge factor.
And this is just at the DRagstrip.. On a race course, there is going to be no comparison.. The GT500 will just be too heavy to keep up.
The Gt500 will most likely respond well to mods and most likely will go as fast as the ZO6, with a few grand in mods..
But its not going to be anywhere as simple as you think.. And you will need a 550rwhp Gt500 to do it.. Which is no small task.
For the guys that just want to just buy a car,not have to worry about the aftermarket, and want a warranty, the ZO6 is hard to beat..
