N2 realism

Well, I can see how Sierra's really done a great job with the physics model. The car really handles like something 3400lbs. But I recently converted an ICR track to N2. In a road course like that, there is of course alot of accelerating. Then it came to me. These cars accelerate no better than my daily driver! I did some performance testing and got something like 0-60 in 6.7 seconds and 0-100 in 11.3 seconds with no wheel spin. This can't be right. Then I proceeded to test the rest of the engine's RPM range. No different. 30-90 in about the same amount of time. The horsepower curve is linear. There is no peak torque and it seem like it is "averaged out". If they ever come out with N3, I't would be great to see an engine with a real or believable horsepower curve. So you can actually feel the "meat" of the power band. Well regardless, I think N2 is still my favorite game and no other sim makes you feel like your'e actually drafting inches behind Gordon and bangin' doors with Iron Man.

Part of the problem is that the racing motors need either clutch slip or wheel-spin to get the best 0-60 times. Otherwise, the RPMs are too low, well below the "meat" of the powerband. Here, I can assure you that you are completely wrong. Here again, I *know* there is a cubic function for horsepower, which is a pretty fair approximation of reality. ---Jim

I think it would be kind of fun to alter the characteristics of the power curve. Race with a torque heavy curve with low peak power at Martinsville, or a peaky no torque curve at Talladega. Just a thought. -Dirt-

Jim, Yes youre right, my mistake. I double checked again this time in higher gears, and yes the car accelerates harder at higher RPMs. What I really meant was the torque curve. It seems like the peak torque is as high as you can rev the engine. If the engines were a bit more realistic, the This is pretty much good enough for me, but I just wish the car would accelerate more realistically in 1st. Later, Adrian

I agree Adrian. In Nascar 2 the acceleration in 1st is rather dull. If you try and avoid spinning the rears tires the acceleration is sluggish. I believe that 70% or below throttle and the tires won't spin. If you have run "A Need For Speed" in the Viper for instance the 1st gear ecceleration has a most realistic feel. The engine sounds like it is working down low and the car gets up and goes. If you rev the engine first then jam it in gear you get the wheel spin. Also as the tires are slipping you tend to have better control of the car, whereas Nascar 2 gets a little too loose under tire spin. I too hope this is addressed in Nascar 3. Still, Nascar 2 is the best racing sim in my opinion. Cheers -- Nigel of Lakewood Motorsports (Memeber of the Nascar Offline Racing Series) Nascar Coruba & Coke Chevy Hamilton New Zealand
