Although not directly on the topic of your thread, the old skool hot rodders' ways are ultimately the best:

1. Reduced weight;
2. Reduced parasitic drag on the engine;
3. Reduced drag;
4. Increased air;
5. Increased fuel;
6. Gearing;
7. Making sure everything else runs "correctly"


So, as other folks have said in one way or another on the various forums, reduce the curb weight to under 3,000 pounds if you can -- good luck. Carbon Fiber is very sexy but very time consuming as well. Figure out ways to reduce the drag on the engine, e.g., getting rid of this or that pump; Lower the car for example or whatever to reduce drag; Increase the air or at least the quality of air, e.g., intercooler and removal of whatever restrictions you can. The Turbo ... ah, the turbo. Alot of time has been devoted to this, and I still have not found one drop in replacement which is the silver bullet cure to this issue; more fuel, e.g., mod'd IP, larger flow nozzles; higher geared rear end for off the line peppiness. After being a forum member on STD, there's no one answer which fits all solutions. Look at the C-111 for the ultimate performance in a OM617.952A engine. It still has world records standing I beleive.
