steve_m Posted October 23, 2005 Posted October 23, 2005 Small V8 Looks interesting, very light, compact and much cheaper than PowerTEC/whoever is making V8's this week. Quote
Blatman Posted October 23, 2005 Posted October 23, 2005 1/4 size engine. Being as the IRL V8's are small anyway, that'll be tiny. It's for big model cars and nothing else... Quote

davidgh Posted October 23, 2005 Posted October 23, 2005 It's a while since I was at school, but....... ....remember we're talking about volume here. Quarter dimension is going to give 1/64th volume if I remember correctly! Bore = 0.915" = 2.32cm Piston area = pi x 2.32 x 2.32 / 4 cm2 = 4.24cm2 Stroke = 0.723" = 1.836cm Swept volume = 4.24 x 1.836 = 7.786cm3 8 cylinders = 8 x 7.786 = 62.29cm3 (So, presumably, the original is 4 litres!

neilb Posted October 23, 2005 Posted October 23, 2005 The IRL Aurora V8 is based on the production 4.0-liter DOHC 32-valve Aurora V8 that is available exclusively in the Aurora luxury performance sedan. As required by the IRL rules, the competition engine retains the production Aurora V8's basic "architecture" -- its 102mm cylinder bore spacing, 90-degree bank angle, and chaindriven camshafts. The street and racing versions also share similar technology, including lightweight aluminum construction, dual overhead camshafts, multi-valve combustion chamber design, and advanced electronic engine management. The production Aurora V8 engine produces 250 horsepower at 5,600 rpm on unleaded gasoline; the methanol-burning IRL Aurora V8 racing engine produces over 700 horsepower and revs to 10,500 rpm. I think that the real thing might be a better idea??? Quote
steve_m Posted October 23, 2005 Author Posted October 23, 2005 I think that the real thing might be a better idea??? OK, maybe there was a lacking in my original post but I fully understand the size of this engine, it is not a real engine Quote
