   Was wondering what you guys think a rough power estimate would be running my spec when finished:
   
   spec:
   
   vtr engine
   forged wossner low comp pistons
   forged wossner rods
   piper turbo spec cam
   competition bearings
   forge intercooler
   apexi avcr
   dp engineering turbo kit with gt28r turbo
   helix aluminium flywheel
   4 paddle clutch
   vtr box rebuilt with quaife atb lsd
   2.5 inch custom exhaust
   
   if i was running this spec at 15 psi, what do you think a realistic power figure at the fly would be?

   Cant really say, thers too much that can effect power.

   I started off thinking it'd be a turbo spec and around the 200bhp mark but looking at that I'd say nearer the 300bhp atf mark.

   I was thinking around 250 to the fly so 300 sounds great to me!!!
   
   Do you think i could run more than 15 psi reliably?

   Try out 16 psi and see if its ok. Then just build it up
   
   Dont push it too far though, or things may go bang.

   Is the Apexi doing the fuelling? Piggybacking onto the standard system? Controlling 4 larger injectors in the standard position, or extra injectors? I'm assuming it can only adjust the basic fuelling, and not ignition timings etc?
   
   Don't think i've ever heard of a boosted 8v getting very close to 200@wheels.
   I'd like to see it get 250+@fly. Realistically i'd guess about 200-220@fly.
   
   Should be an awesome torque figure though

   There will be 4 larger injectors in the standard position, your correct the apexi will not control ignition timing, there will be a standalone ecu from jamsport!
