Default Mods done! guess my HP

So I have finished the mods for this winter ( yes allready.....)

Since snow and heavy rain has hit Denmark, the 87 is now in the garage. AND I dont have acess to a Dyno here in DK.

SO PLEASE GIVE YOUR GUESS ON MY HP NUMBERS.


Strong running (before mods) 87 A4. 90k miles

Mods:
  • Super Ram intake (good portet)
  • 1.6 roller rockers (+ Compcam guides, Push rods, APR 7/16 studs)
  • BBK AFPR
  • 160 T-stat
  • K&N + cut lid
  • Airfoil
  • AIR delete (Breathless Perforamnce)
  • Lingenfelter LT headers
  • Lingenfelter front Y (no cats)
  • NO main cat (straight pipe)
  • Borla SS cat-back
  • Costume chip by ski_dwn_it (in progress)

Tried to add it all up "ecklers style", and ended up frying my calculator

250-260 RWHP. The stock base will be a limiting factor, but you already know that.

270 hp. LTs exhaust and super ram should get you close to that.

Lars, you forgot to mention the 1.6:1 ProMags...

The guys are talking RWHP and (I believe) you are thinking CHP.

In any case, since the only thing you have not done is heads, I would take a stab at around 350chp or 290rwhp...

Though you will need to add new valve springs to safely rev into the 6k range to really benefit from that SR intake, IMHO.

Once she's tuned let us know if you can get some dyno data.
