Well, I took the car to the dyno today to see what the car would put down on 15-16psi of boost using 92 octane pump gas.
The car did 468whp, and she was pig rich the whole time. AFR was at 10.9-1 the entire time. Obviously I could of turned it up to 18psi and probably pushed 500whp, but thats kind of on the razor's edge, and I like to keep things safe
I'll be taking the car back in a couple weeks with some C16 in there to see what it'll do at 25psi! Looking at the dyno curve the turbo was still pulling hard at redline...obviously!
The pervious owner said it put down close to 700whp at 25psi so I'm hoping to duplicate :dunno:
Here is my list of mods, if you have any question or comments, I'd love to see them!

Pictures will be up later and if someone can host a short 30 second vid, I would send it to you email or however you need to get it.
number seems kind of low for a sp67 with a .81 a/r. Is this a Q trim or P?I thought espically with a full raceported head with 1mm over sized valves youll be a little higher, but than again your a/f was super rich at 10.9. Post the dyno sheet!
Nice numbers. I did 518rwhp/475rwtq on my sp67 p trim with a .68 a/r at 19 psi on a 7m-gte and 450/418 at 15 psi at an 11.5 to 11.7 a/f so those numbers are pretty good in my opinion. I would say you could break 500 rwhp just by leaning out your fuel curve to 11.5 to 11.7 at 15 to 16 psi. So again nice job!
With the octane your using, I would say push no more than 17 psi and don't let the a/f's get over 11.3 on the dyno. If it's at 11.3 on the dyno, it will be around 11.5-6 on the street which wuold be perfect. With this in mind, you wuold probably easily push 500rwhp. Sounds like you got a strong setup, the only thing hurting you is the safe tune ya got. Better safe then sorry!

As for the comments on the headword and what not, like banton said, that isn't going to really help me down low, on low boost. It's more for higher boost. Like I said, I'll be taking it back in about 2 weeks with 25lbs and race gas I'll probably still have it running rich though.
I really don't want to blow my motor. I'd much rather make a little less power and save my engine...it's just me :freak:
I need to get a G-force so I can raise the rev-limiter, when I post the dyno graph you'll see how the turbo just wants to keep climbing!
Oh, and just for the record, the car did 620whp and 599wtq on a mustang dyno at 25lbs. I'm not sure what that is on a dyno jet??? Maybe someone can help me figure out that calulation!
I'll be finding out in a couple weeks anyway :bigthumb:
I don't know what they are going for?? I've got an AEM going in soon. I'm waiting on a 4" DP and deciding on which exhaust to get. Than I need to have it tuned.
