Dyno Sheet Petition - ZR-1 Net Registry Forums

LGAFF · 07-10-2010

There are several on line petition sites that are free or very reasonable in costs.....wondering if anyone is interested in pursuing this? I did write up a quick note to attach and certainly open to redrafting....

Hello,

I am a proud member of the General Motors family, an owner of a C4 Corvette ZR-1, as well as a member of the ZR-1 registry. As you know, the C4 ZR-1 holds a special place in both Corvette and GM history; the first DOHC Corvette motor, the 24hr endurance record at Ft. Stockton, as well a placing the Corvette in supercar status with the likes of Ferrari and Lamborghini.

As a member of the ZR-1 Registry, we continue as caretakers of this unique automotive icon. Over the years, as support for the ZR-1 has dwindled and parts become scarce, we have pooled our resources to manufacture our own gaskets, bearings, and other items required to maintain the Heart of the Beast.

We have also pooled our resources to continue the development of the LT-5 motor, including development of large displacement small block LT-5s that produce over 600hp. Other automotive enthusiasts are amazed as this 20 year old legend continues to compete with newer automotive technology.

Lastly, we are preservationist of history, collecting articles, preproduction pieces, as well as supporting NCRS restorations. However, one piece continues to elude us, the original dyno sheets from Mercury Marine, each one unique to each of the 6,939 ZR-1 LT-5 engines produced from 1990-1995. Currently, the dyno sheets are housed at the National Corvette Museum. We have been informed that GM forbids the distribution of these sheets to the public.

We are writing to you requesting that the dyno sheets be released, in copy form, to current owners of C4 ZR-1s so that we can add this final piece to the legendary puzzle. Certainly this is a great opportunity to generate revenue and support for the National Corvette Museum as well as display your support for caretakers of this unique piece of GM history.
We anxiously await your reply and thank you for your time.

Man Lee nice writing talents! You are the Wordsmith!

Okay, I'm in. I would pay to obtain a copy of my motor's original MM test cell dyno sheet.

What do i do to support your efforts in this matter? Sorry if I'm a bit dense....but whom do I write to in support of your effort?

I'll join in.

All the talk seems to be about the 375 hp engine being possibly short of its advertized horse power. Does this mean that the 405 hp LT5's were spot on, or nearly, and that copies of the dyno sheets are going to be easier to get?

The Motor Trend article that did top speed testing vs. Jay Leno's black Viper had the 405hp motor a little down on power according to the dyno chart. But who knows what correction factor they were using.

I would find it hard to believe the 375hp cars were short considering that they ran the same or faster quarter mile times than later cars with 405hp, with minimal changes in body weight.

At some point they will release them.

I'd love to have the dyno sheet for my car, nice writing Lee and good luck with getting to the top of the food chain with the request.
