[DML] Re: Delorean Choice of PRV

["therealdmcvegas" <dmcvegas@xxxxxxxxx>]

Actually, that still only half-true.

An engine does have to be certified on it's own as an engine. That in itself IS a lengthy 
process. Next it must be tested in an individual vehicle platform, which is a far less 
lengthy process comparatively. This proves that under load of a particular vehicle 
platform, it still stays withing emissions standards.

http://www.epa.gov/otaq/certdata.htm

I.e. a Ford 302/5.0L V8 engine would be tested as an engine for meeting emissions 
standards, and would then have had 2 seperate tests performed on it to see how well it 
does when installed into separate vehicle plaforms: 1. FOX Body (Mustang/Capri/Crown 
Victoria/Grand Marquis), 2. Light Truck (F-150/Bronco). And so on as the new vehicle 
platforms are introduced, and new engine options are introduced as well.

2nd example: AMC 2.5L I-4. First tested as an individual engine, and then proven it would 
work fine within the light truck platform, it could be installed into Jeep Wrangler/
Cherokee/Dodge Dakota (1996 only). But then when it was installed into cars, it had to go 
through new rounds of brief testing. Then it was installed into the Dodge Monaco and 
Eagle Premier with share the same platform.

So, with the DeLorean, the PRV was the best choice at the time it seemed (it seems like the 
Rover V8 would have fit the bill better). The engine was already certified to be used within 
the United States, and would only undergo minimal testing for emissions to prove it would 
do well when installed into the DMC-12. This also lead to severely detuning the engine, 
and installing such a restrictive catalytic convertor. The went overboard to ensure that no 
delays. In any case, no, the engine wasn't just a drop-in, but yes he engine was chosen 
because it had the most lengthy and expensive testing on it already completed.
