Dyno Sheet Petition - ZR-1 Net Registry Forums

tomtom72 · 12-29-2011

Good Afternoon,

I am a member of the ZR-1NetRegistry. Our Registry is devoted to the preservation of the fourth generation Corvette ZR-1. Most of our members actually own one of these fine examples of GM's engineering prowess. I own a 1990 car number 2233. My particular interest in writing is to respectfully request that owners of this wonderful machine, having proved ownership, be allowed to obtain copies of their car's motor dyno test results.

In the realm of mass produced automotive motors our LT5 motors are a high water mark in that these motors were, and still are, the only hand built motors in any GM product for public consumption. I wish to be very clear that our LT5's were not just 'hand assembled'. LT5 components arrived at the Stillwater, Oklahoma Mercury Marine plant mostly as unfinished castings. Mercury Marine employees had to finish machine the major components and then assemble the motor. Once completed each motor was tested in an engine dyno test cell for performance verification and mechanical break in. Having passed it was then released to the Bowling Green plant for assembly into a ZR-1 chassis. As a consequence of this method of production each LT5 has a "birth certificate", it has a dyno test sheet. This dyno sheet was kept with each motor as it's own 'build sheet' and when it was joined to a ZR-1 chassis the chassis number was stamped on the motor at that time. This is a subtle point, but it completes the numbers matching documentation that all Corvettes enjoy to this day.

I would add that the National Corvette Museum has custody of these dyno test sheets as it is one of their preservation functions where the history of the Corvette is concerned. They are the guardians of all the original documentation of all Corvettes produced at the Bowling Green plant. I should think that as they offer reproduction window stickers and build sheets presently, they would be very receptive to augmenting their income stream with offering reproduction LT5 dyno test sheets.

I would close by thanking you for your time and for any assistance you could provide in our quest to complete the documentation of our ZR-1 Corvettes.

Respectfully,
Thomas Del Guidice thomastom72@aol.com

Okay so this is the direction that I chose to take with my e-mail. I hope it is enough on message with everyone else?
