Bob, if they LET an IRL car run with something like an R10, it probably COULD win the 500, since it wouldn't have to pit as often. And the acceleration would have to be rocketlike, I'm sure (from experience running my truck at a clutch burning SW 5 on my Smarty--go to madselectronics.com ) A 500 mile race is as much about fuel management as anything. I promise you, when they let ANOTHER diesel powered car in Indy, I WILL TALK. And I wonít be the only one.<quoted text>
I said that diesel gives better fuel economy especially while hauling heavy loads, but you lose that when you drive fast. Nothing you've said contradicts that. It's good to know that your souped-up truck can blow somebody's VW off the road, and that a diesel can win an endurance event. When one wins, the Indy 500, then you can talk.
Your knowledge of modern diesel technology is underwhelming. For $700, I can get over 500 HP out of my engine, but the rest of the drivetrain won't handle it. I'm talking about a 2005 Ram with an Inline 6 High Pressure Common Rail Cummins 5.9, not a 89 model with a VE rotary pump and no intercooler, etc.
Any machine will lose in the fuel economy area when it runs above itís optimum Brake Specific Fuel Consumption levels. Combine that with wind resistance and improper gearing, and fuel consumption goes up, WAY UP. My truck (without programmer) lost 5 MPG running thru West TX where the speed limit on I-10 is 80 MPH. Itís pushing a LOT OF AIR, and the transmission is geared for German Autobahn limits for medium duty trucks (62 MPH/100 KPH). Believe me, itís not the engine and fuel that cause the fuel economy loss. Itís a combination of other factors Iíve already mentioned in this paragraph.
Bottom line, I can make so much more power from a turbodiesel with a little cash than I could ever do with a gas engine. You want to know why? It's simple, electronics, direct injection, and the fact that the turbodiesels in these trucks are capable of handling EXTREME PRESSURES by design. Set up right, a 3/4 ton turbodiesel will smoke a stock 07 Mustang GT and still be streetable. The funny part: they NEVER see it coming.
