reads Joe's post on how he figures the HP, somewhere like 5 HP for every lb of boost, if you raised your boost from the stock 7 lbs to 16, you should have gained about 30-40 mhp?? I shore could be wrong.
After redoing my exhaust and intake and chipping it, then a FMIC  with all new piping and removing the ac and cat, then redoing the exhaust one more time, I believe I am running close to 200 hp. Makes the rich kids round here wonder wtf is in the car!!!!!

I wouldn't go by such generalized numbers. There is to many variables that could affect the outcome. Temperature, humidity, altitude, general condition of your engine/turbo/ect. Run your car on a dyno a few times. Take it to a 1/4 mile track and make a few passes. Without doing the above, I can tell you my Capri has 250 horses, and with nothing to back it up, who knows?
Once you make a few passes, use this calculator to estimate your HP:

 Horsepower Calculator

I hope to have a few passes by summers end, and timeslips to back up any numbers I will post afterward. I have a number that I think my car is putting out, and I may be surprised to find I'm way off. I hope not, but I will do both 1/4 mile and dyno to find out for sure.

Noone here has the dyno #'s to back it up... noone There are calculators, etc. but no solid numbers yet. It seems everyone chooses to dump their money into more go-fast bits than to have dyno proven numbers.
