LS1
My thought on the Cobra R (if in fact it was only pulling 13's in the quarter) are that it must have been highly overrated. There are lots of road course cars out there that are designed just for the road course and still kick some *** at the drag strip at the same time. I understand that super hard front and back springs and some of the other road course stuff can make it a hard car to launch. But just getting into the 13's with what was said to be making 385rwhp(as OICW stated)is very bad. Now if it was just 385 crank, then it should be making around 335rwhp or so(which sounds more likely to me). Then i can see it only getting low 13's. I still think it should perform better than that, being as its a stripper car, but i would think that 13's would be because its a mag test or manufacturer quote, it could probably actually do more like high 12's. Still too much money for a high 12 second car. Again keep in mind though, it was made for the road course, so if we dont know how it performs there, it is hard to estimate its value to performance enthusiasts that actually only care about performance and priding.
It was true up until about two or three years ago. There where only a couple of home made true duals made and no product available to us. But now there a a couple of true dual products you can purchase for an LS1. I think GMMG makes one of the more popular ones.
Don't feel bad man, that's why this thread is here. You're nowhere near being the first to do what you did. Hence the reason this is stickied at the top. Hopefully others will see it.
What information are you looking for. They are lighter than the original vette, come with 405hp, have a different block, heads, and cam than an LS1. The mufflers are made of titanium to cut weight. They have closer gears in the tranny, which equate to having around 3.90's in the rear. Stock they are an easy 12.4@ around 116 and some crazy good drivers have gotten 11's with them bone stock. Any other questions?
