Default Sometimes I wonder...

Sometime I wonder what goes through the mind of some of these hotshots.
As an example, I was driving the ZR earlier today as I was doing some
datalogging. Low and behold up from behind comes a rather nasty sounding
5.0L Coyote Mustang. So he pulls up next to me and gives me a quick snap of the throttle while he's in neutral. The wxhaust note is pretty nasty sounding.
So sometimes I wonder, does he know what the ZR-1 moniker means?
But what I really wonder about is what does this guy in the 5.0 think, after demonstrating his nasty Coyote motor, that this 25 year old C4 Corvette decides to just jump in behind to stalk him. Hmmm.

Well if he was thinking that, he would be very wrong.
Frankly, I think he was just snorting and clearing his exhaust in the face of a lowly 25 year old C4 Corvette. I thought I would get into his rearview mirror and give him something to wonder about.

Well what I know that the guy in the mustang doesn't is that I beat the numbers mjn posted for Mustang. Except I beat them at the rear wheels and not at the crank.

I had the Z06 NPP exhaust valves closed at that point. I love sleepers.

The thing is the ZR-1 was king of the time, but a new mustang with a tune and full exhaust will hand us our lunch.

We have to have some serious mods to compete with new cars. Its just a fact and part of the game. I will say I beat a full bolt on 2003 Mach 1 a few years ago in my close to stock ZR-1. He thought I had a stock C4 LTx. When I popped the hood he was amazed at the engine. He had never seen one in person.

If u start out w a decent ZR-1 w an initial investment of 15-18k, do your own top end porting and exhaust, possibly a SM FW, you are now at about 470chp for a total investment of say 21k.
Add cams and head porting for another 3-5k, and you have a ~540chp for
roughly 25k total. And that's staying w stock displacement.
Another alternative would be to go w Pete's Closed Deck mod from the start w that same 15-18k stock car, and now u r in 600chp territory for about
the same total 25k investment. An incredible performance bargain and less than half of a stock Coyote Mustang.

Some ZR-1s w top end porting,headers and exhaust can even be had for mid to upper teens......Go to the next step, head porting and cams and you have over 500 HP barely breaking the 20K price...
Tough to find that in other used cars today.....
