The ZR1 is built built for road racing not straight line performance, but I am sure that you already are aware of this, given your experience.
The ZR1 is a total package. Body, Suspension, Brakes, motors and refined interior. I don't really care for the hood with the blower showing and all of the carbon fiber parts.
Overall, It's a great car, just a little pricey.

I'm a drag racer but I always thought FI was not ideal on a road course.

I'm just talking bang for the buck here , a ZR1 is all about the prestige of having one . I'm not all about straight line performance , most of the hi-tech options on the car will never be put to the test on the street , I'm sure it won't be long before a new ZR1 gets it's azs handed to it by a C6Z06 or C6 with a few mods . A nice big cowl hood would've looked a lot better than the glass one .
A&A's new intercooler design may change the old road racing rules of N/A is best. Maybe a nice motor with 5-7 psi of boost will be do able at the track.

This conversation has been happening since I was posting in the C4 forums.
If you want one of the best supercars available in the world today, (as well as American made and the best value), there is only one, ZR1.
- Why buy a C5, I can make my C4 make the same horsepower for a lot less. Than it was...
- Why buy a C5 Z06, I can make my C5 make the same horsepower for a lot less. Than it was...
- Why buy a C6, I can make my C5 make the same horsepower for a lot less. Than it was...
- Why buy a C6 Z06, I can make my C5/C6 make the same horsepower for a lot less. Now it's...
- Why buy a ZR1, I can make my C5/C6/C6 Z06 make the same horsepower for a lot less.

Nicky and Jose fabricated an 1 7/8 inch header, custom X pipe and free flowing cats for the car. With some basic tuning with EFI Live (not wanting to push this beast just yet since it only has 200 miles on it) and the 1 7/8 header the car made 598RWHP 549RWTQ! The Dyno sheet shows over 40 RWHP and almost 50 RWTQ over the entire power band! Incredible!!
Here is the dyno sheet:
We also tried an 1/34 header which should a significant loss over the larger header. The larger header is the way to go.
We have left a lot more power on the table with the tune as again I only pulled the car a couple times on the dyno with the new ARH exhaust system and left a very conservative tune in it. Thanks again to Chad for getting me the software. The EFI Live software for the 09 ZR1 worked great. I personally drove the car after I tuned the car and I can say this thing runs great!
We have another customer picking up their new ZR1 next week. He is looking for an even more aggressive package. We are working on a custom pulley system and air box, both should really help this beast reach its full potential. I can tell you now that replacing the pulley is not going to be as easy as it is on a Magnusson but we think it will be possible with some creative designing.
Here are several pictures of the install:
