Like I said in the other thread, with a balanced bottom end, cruising around at 4500 is natural and clean. It is kind of like driving around a sport bike, where "put put" at 6000rpm is not a big deal. Now I notice it. I am sure my fuel economy has gone up as I am aware of the extra vibration. There are two sets of resonants from my butt butt dyno, without any math or real live data. It feels like there is a bit of a vibration at 3600, and another at around 6800. I am still reving to 8500, and it still makes a silly amount of power at that level. I am using an adjustable cam gear now, and 4 degree's of retard flows a stupid amount more of air. Javad back in the day picked up 63whp by retarding the cam timing 4 degrees( from ~485whp to ~543). I feel like I did the same thing. Put it this way
Put it this way, if I were to take the engine out again and had the time, I would take it apart to balance it. For the 250$, it is a hell of a mod that makes the car feel so much more refined. Remember how smooth the 20v felt after coming from the 20v? Kindof like that.
On another note, I am using an adjustable cam gear now, and 4 degree's of retard flows a stupid amount more of air. Javad back in the day picked up 63whp by retarding the cam timing 4 degrees( from ~485whp to ~543). I feel like I did the same thing. Put it this way, with the cam timing at tdc, I could run 90% duty cycle on the injectors at 34psi with ~1400cc injectors. With the cam timing retarded 4 degrees, 90%DC occurs at 28psi. A ton more air is getting in and out of the motor with the retard. I recommend the mod to anybody as long as the turbo still has enough in it(reading jimmy??)
Hey Hank
Way to go gettin her back on the road again. Wait a minute, oh nevah mind. Anyway, I've also got the 034 cam adjustable gear and when Tufty and Brendan were playing around with it there was no perceivable difference whether they went advance or retard with it. Tufty attributes this to the high lift and duration of my custom cams. I also plotted my boost against your graph and you've got me beat by 800 rpm. I don't get to 26 lbs until 4800 rpm. I'm also putting out something on the order of 587 ft/lbs at that same rpm. Can you say, " Freight Train!". Well, congratulations once again. BTW, I'm taking the Monster out today to see if I can find some poor fella in a Super Car.
Hap, with some kind of game near Everboost, Maguire
It's funny
