Do these numbers look normal?

231hp
270tq.

Absolutely bone stock. No modifications whatsoever. I haven't even looked at the air filter.

It's about 55hp/tq drivetrain loss. 19%hp loss. 17%tq loss.

I was hoping for 240hp.

 

Not too bad for a bone stock A4 car. Do a basic tuneup (plugs, wires, air filter, fuel filter). Stuff like that will make a car gradually lose power. How many miles are on it?

 

I ve always heard that m6 have about 15% drivetrain loss and a4 around 20% so your number seems ok for a fully stock car.

 

Motor has 70k and new plugs, though i have no idea what they are gapped at.

Car itself has 100k miles.

I have an intake cutout and 3000 stall ready to go on.

 

Your numbers seem pretty close to what a bone stock A4 should be putting up.

 

Not bad at all, average stock dyno for an A4 car is in the area of 225rwhp and 250ish rwtq.

 

Sorry, didn't see you have a '97, those numbers are about right on then.
