Hmm pretty strange, my 1JZ dynoed 450 rwhp and rwtq on 20 psi and pump. Pretty similar turbo to yours too. Where did all your torque go?
When we lean out the a/f around the 4500 to 6000 range the torque climb to about 440.
I am not a friend of lean so we brought it down to rich and sacrifice a bit of torque.

It hits around 4200-4500, Powerband responds at 4600. Cruising on 5th, I can squeeze it and get 20psi by 3900

hi drewgo

the afc can not adjust the middle (between 4000-5000)? Also on the 7k rpm. 12.3 afr. Tad lean no?

about the 4000-5000 rpm point, It would actually help with spool and of course power producing too. Being that rich, man, at least mosquitos won't bother you at all. lol

yeah that was corrected to bring it down to 11.8. I am retuning as soon as I get a chance. I am adding some more goodies to the equation.

Does this setup on stock cams have more in it?
We've done 591rwhp on a pt67 and 680inj and SAFC. So yeah the set up will give you more. However wont go passed 620's or so due to head restriction, you can get more if you add cams.

Very nice setup drewgo! :) I hope with my GT35 I can achieve 440rwhp or better!

I am sure you will, just get big injectors so you don't end up like me blowing up engines and stuff.

So you think you can make 500whp on pump w/out cams?

Yes, it's been done. Cams do add horses, but one of the things they do Is give you a better power curve. But yes you can make well over 550 with out cames.

I've been present to witness this.

On this turbo though right? I always hear people looking for 500 on pump go with like a gt35 or 40r and I haven't seen anyone (from here at least), pusing 500 even on these.

No not on these, PT67. Theser are good for high 4xx or low 5xx. I would not expect these to be there on pump. IVe reach 485 with my gt40.So yeah you can do it with these but to go 600 I would say this would not be the way
