Dynoed my car a couple weeks ago on a Mustang dyno- 227 hp, 203 ft-lb torque

Rebuilt S4 block with new S5 housing- 1600 miles on it
Steetported- racing beat intake and exhaust templates
Corksport 80mm turboback exhaust
3 inch TID
Stock S4 Turbo 11psi, dropped to 8 psi by redline
Greddy FMIC V-spec
550cc and 1600cc injectors
3rd gen fuel pump
Centerforce dual friction piece of **** clutch
Haltech E6K- afrs are in the high 10s, timing map untouched from base map

 

Not bad.

What boost controller are you using? You might be able to squeeze out more power by bringing the afr's to low 11's, especially with a streetport.

I made similar numbers on my setup which is similar to yours, cept I have a tmic, stock ports, and 550cc x 4

 

Boost controller- Home Depot ball and spring special

 

That's some pretty good power...
Talking about in the range of 250 on a DynoJet...

Sounds nice

 

very nice

 

Last week I got my car Dynoed to see what the result would bes before I get new turbo back exhaust and only showed 140 rwhp and 198ftlbs torque. I have no mods what soever stock exhaust ecu air filter etc. seems a little low on HP. Car shows 79,000 Klm (about 50,000 miles) and the Dyno used was 2WD Mainline. Boost should have been stock also. Any thoughts
