[QUOTE="Arun, post: 44586, member: 1488"] I don't get impressed very often-but over the weekend I sure was so I just had to share. Ever since GM switched over to the square port head to the cathedral port head there had been alot of rumblings as to what the hell were they thinking. Big giant slow moving 260cc runners versus the fast moving 200cc runners-are going to hurt torque and low speed power-boy GM knew exactly what they were doing. Last week I had the opportunity to dyno 3 cars-a stock C6 LS3 with headers, a 2010 Camaro where we installed headers and one of our custom cams and a 2010 C6 where installed a ECS 1500 kit, meth, Bosch 1000cc injectors and ECS stage 1 fuel system-this car already had a cam and headers. The results were very impressive-the C6 with just headers belted out 394 rwhp-no stat, no cold air-and it made an equal amount of torque to boot. You honestly have to drive the car to appreciate how smooth and how torquey these LS3's feel. The 2010 Camaro basically has the same engine as the C6-so we bolted on some headers a CAI and of our blower cams-you might as why a blower cam-reason being this car has future plans of a supercharger. Using 394 rwhp as our baseline our cam was worth 58 rwhp and 23 rwtq-with no sacrifice in power down low. So we are now at 452 rwhp-coming from the cathedral port world it would take alot more than just a cam to get there with a LS1/6 or 2-and when you did get there the car would be nasty-this is were the LS3 shines-it drives like butter-very little to no bucking or surging-you can lug it down to 1300 rpm and cruise if you wanted you. Next up was the C6 from Montreal we finsihed up before the weekend. Can you believe at just 12 psi this car made 744 rwhp and 624 rwtq-and the scary thing is I could of gotten more out of. In fact when we made 733 rwhp we were all estatic-but I as always wanted safe so I added more fuel and pulled out some timing and it gave us even more power. That is now a gain of 292 rwhp over the 452 rwhp or a gain of 350 rwhp over the baseline of 394 rwhp-that's a crazy 29 horsepower per pound of boost. So for all you C6 owners with a LS3-your lucky, and you C6 owners with LS2's are pretty lucky as well-because the LS3 heads bolt right up. I am real excited about these new motors-so much so that my new combo for this season is a 364 with LSA/3 heads-but I'll be throwing 25+ lbs of boost to them:D. Here are the dyno numbers.
