I thought that high revving in neutral was very bad for the engine, or am I mistaken?

I would set the rev limiter at 5200rpm so then its not bad because thats right at redline.

Have run 0-60 in 8.4 seconds (repeated) with a stock "C" 3800. The car is really deceptive because the torque curve is so flat - peak at 210 lb-ft at 2100 rpm and still making nearly 170 lb-ft at 5200.

The result is that there is no sensation of rising accelleration, it just goes faster.

Factory cuts the fuel because raw gas in the exhaust does nasty things to the cat.

wow.... very interesting stuff that I didn't know about my 91 padgett..... you are one very smart bunny rabbit....

2 Questions...
1)What should my 91'* RPMs be at if I'm cruising at 100kph?

2)I run stock igntion control boxes, but I have high quality plugs and wires on both my cars.... should I consider upgrading the boxes... is it really worth it?
