Guest rationull Posted May 25, 2006 Share Posted May 25, 2006 I'm new to Z cars and something of a paranoid wuss when it comes to engine speed (my old car's engine was a bit more fragile than the L28). Just for my own peace of mind, I decided not to fight the temptation to ask: How high do you guys usually rev your engines when accelerating, and for cruising? (mine is an 83 280zx NA just for information). Quote Link to comment Share on other sites More sharing options...
racerx260 Posted May 25, 2006 Share Posted May 25, 2006 The tach yellows at 6500 and reds at7000. However power peaks at about 5600 on older z's and about 5200 on zx's. So on a stock zx theres not much point in reving past 6000 and thats just to drop in at a higher rpm when you shift.If yours engines heathy you can rev it to 6000-6500 all day long if you want.welcome to the world of z's.

oinojo Posted May 25, 2006 Share Posted May 25, 2006 as you can see on my dyno chart, power drops significantly after 5500. I am running an l28 on su carbs. My A/F is constant until 5000 then it starts to run extremely rich which led to the drop in power. With a better cam i can see this motor running 6500-7 no problem.
