So I went to the dyno again to get some bigger numbers and some more tunning. With pump gas (94) and 14 psi It made 394 hp and about 375 tq.
So I put in some C-16 and at 22 psi made 499.2 rwhp and about 465 tq. I know its not exactly 500 but I think thats close enough for me.
I did however max out my top feed Denso 550's, the injectors were at 100% duty cycle according to the E-manage. We tried to up the fuel pressure but it didnt change the A/F's. So I could have easilly bumped up the boost another 1/2 pound but the A/F's were at about 12.5's so I didnt want to melt my engine just to get another .8 hp, LOL. So 550's on a 1JZ are good for 500rwhp max.
Next step is to get some 62 lb ( 680 cc) injectors, turn up the boost to about 25 psi. I figure that should make about 520-530 rwhp, I think that will be about all the GT28R turbos can do. That should do for now.........
