Doug Fehan tells stories and takes questions, including mine about the new, pre-production, 5.5L LS3-based engine that continues to cause other teams to question the unfair advantage GM has (despite no other team adhering to the new ACO rules, while Corvette has).
For those that don't know, the LS3 is the lowest-end, naturally aspirated 6.2L Corvette engine in production. The new, pre-production, hastily designed, racing 2010 Corvette C6.R GT2 takes the LS3 -- but it has been shrunk to 5.5L to meet new ACO requirements in GT2. Originally the ACO allowed Corvette to run a 6.0L version of the naturally aspirated 7.0L LS7 engine from the Z06 in the partial GT2 class Corvette ran in '09, but that caused competitor outcry. No other production car vendor in any LeMans class (now that Aston-Martin is no longer in GT) can produce a naturally aspirated engine that competes with even Corvette's lowest-end, production LS3 (let alone the LS7, which was designed alongside the production Z06). Again,tThe pre-production 5.5L was a rush job, developed only in months, to meet the new ACO requirements. Unfortunately, no direct gasoline injection has been added -- unlike prior designs and allowed by ACO -- because other teams, in the economic downturn -- have not developed them.
Several production GM performance engines, including those in the Camaro and newer Corvette prototypes, have the direct gasoline injection design, increasing fuel efficiency 10-15%. Even without it, Corvette is already the most fuel efficient sports car in the world. In GT2, less pits were killing the competition with it -- so GM agreed to take it out).
Doug Fehan talks at length about this in many videos over on www.corvetteblogger.com.
The one where I ask about the 5.5L is in this one (my question is at 7:58 -- Doug actually talked about it longer than when this video ends):

Oltre che per le sue dimensioni ...

Walking around the LS3 area, I found a bridge that looked over a dual carriage way, and I wanted to try out some shutter speed with my new camera. Forever one of my favourite techniques, and I can't wait to go out later again tomorrow to get more results!
