You know....what has me bu$$ered is exactly how much is enough.
Like, I'm looking at the LS1 site and in the GM Motorsport forum. In the stickies there is a post about a SS Thunder ute with a 6 Ltr completely standard ( stock exhausts) which did a 13.9 @ 102 (about)
Then underwent a mafless tune and did a 12.9 @109.5...all bog standard with bugga all miles on it.
And all the while having traction problems!!!!!
Now this thing weighs what??....1625Kg.?.
I'll leave it to the more expert than me to guess what this same powerplant in a say....1140 Kg.? cobra would achieve.
My post clearly mentioned Street car as opposed to track cars but also mentioned being able to blow off most ex showroom cars.
Sure, most of us will install aftermarket cams etc but my point stands...the stock manifolds will not stifle a standard ( as presented for rego) lightweight cobra which can in that stage of development give a hell of a fright to most cars ex showroom.
There is another area which I suggest many on here don't realize. You can build these things...purchase the best brakes, springs, shocks and all sorts of mickey mouse stuff and I'll bet.......you $hit yourself first outing.
You'll more than likely find it wont stop, wont go around corners and you'll find yourself wondering what the hell is going on and having to spend more money than you planned on sorting the thing out.
I'd prefer to get it handling and stopping properly before I find myself short of money because I spent up big on some go fast stuff.
My point is...you really don't have to have all the best of everything ie. cams, extractors etc., to have a well performing cobra...the lack of weight is your best friend.
Cheers
