Hey man.. I think you've never actually seen a measured difference between a stripped out car and a stock one. My 540i stock is good for a 14.6@99mph. After I removed 300kg of weight from it, tuned it, and shortened the diff, it did a best run of

Would you imagine a nearly stock 540i can outpace a Challenger SRT8 from a dig?
Here's a video of my bone stock 540i matching a 355hp Audi S8 from a low roll till around 140mph. Why? Because the S8 weighed 150 kilograms more than my 540i:

Here's a video against a tuned S2000 when my car only had a tune on it:

Stock S2000 is good for 14.1 sec @ 97 mph. Makes sense.
Here's what happened after I stripped it:

Stock M3 is good for a 13.3 s @ 104 mph. That M3 had alot of goodies on it, but from a 20mph roll all the way up to 140mph, he couldn't pull a fender on me. WEIGHT.
It's not a couple of tenths. A proper weight reduction will yield you much, much more time than that. My 540i only made 282whp/299wtq, but the weight advantage kept it competitive. And for what it's worth, I kept my dashboard and all electronics and stuff in the front, where I was. Only behind my seats is when the mess started...
Even if it made the same power, the Fox will be faster as it is LIGHTER than my STRIPPED 540i bone stock. A 300whp GT40 Fox with the right setup is a car that can dip into the high 12's, which is still fast by today's standard.
Don't get me wrong, I received a lesson in modesty from this bone stock 500+ horsepower Range Rover:

More power will eventually win the race, no matter what. I'm the first one to agree to that. My entire point is that basic boltons with the right gearing and good grip, along with a significant diet, will work wonders for the low budget racer.
