Car: 99 TA WS6 w/29k miles (mods in sig). Has stock gears & stock rear.
Dyno: Regular dynojet, not mustang dyno.

When car had shorty headers, ported TB, lid & loudmouth it dyno'd 315/326 (not that impressive IMO, but not bad). With adding Long tubes, off road y-pipe, LS6 intake & F11 cam would you guys think I can hit 400/390 or would that be a stretch? I have my opinion & personally I think I will only be in the 380-390/370-380 range but just looking for others opinions.
Thanks!

385 rwhp

 

might be a stretch to hit 400 but you'll prob be in the 380 area.

 

Yeah thats what I am thinking...in the 380's around 385. I am debating also adding an ASP crank pulley to hopefully get it closer to 400...
