I bought a 2011 Camaro 2LT with variable valve timing, twin cam, 4 valves per cyclinder direct injected V6 (state of the art), the advertised hp is 312. I also bought a used 2002 Z28 with the LS1 engine from the same dealer for a good price. The advertised hp is 310 for the 2002 Z28.
But when I drive each car, the 2002 Z28 seems a whole lot more powerful.
Elapsed time at a control track also proves the z28 is more powerful.
I did some reseach and found that for the 1998 to 2002 LS1 engines, the true hp at the rear wheels on the camaro is more like 350 (same LS1 in the corvettes).
The torque ratings were also dumbed down by GM on these camaros
I have now had my 02 Z28 for 6 yrs. It has 92k miles. The LS1 is great! it can withstand alot of abused. These cars with bolt ons can easily get into the 400hp+ range. but add cam, heads and a real proper tune and you can get 450 to 490rwhp range ..all day long, that translates to 500-550bhp WITHOUT the need for nitros, turbo or supercharger.
These cars were underrated so vette owners didn't have a cow.
LS1's make around 290-310rwhp which is the same as stock Vettes. For people on this board who say the V6 makes V8 power....aaahhhh no... it doesn't. Please get into the V8 FIRST then tell me if your V6 is like a V8. Theres like a 150hp and 150tq difference!
The V6 is not much compared to newer ones, but it will still pick up to highway speeds before you could turn your head to check the other lane. Takes any turn without a problem, good on fuel, and how could you ever forget the nostalgic but mandatory t-tops. Interior is roomy in the front, the back, can be made comfortable if you're sitting alone.
This car is exceptional. I have owned a lot of cars in my life, including a 1968 Camaro, which is the only one that compares to this vehicle in performance. This car has literally saved my lie on several occasions. I don't drive a high performance vehicle to show off, Phoenix roads are dangerous. When I tell my car to do something, I expect an instant result. On at least three occasions, spit second performance has avoided serious accidents. She is asthetically appealing as well. She always turns heads, a nice bonus. She leaks a little in a car wash and the stereo needs upgrade. Everything else is amazing. I am giving this to my son and getting the 2009 when available!
