however there is no direct relationship between boost and hp gain.

If you drop to a 3.5 you might gain 15hp at the crank however a 3.4 will only put you at 10hp over stock, because you have 6* of KR, cancels out any extra boost.

thats IF you have KR right?

145-160 at the wheels depending on tuneup, etc.

Correct.. KR pulls timing and reduces HP output.

However.. running super unleaded (92-93 octane), good intake, good exhaust.. and a 3.4 you should be good. That is pretty close to my mods in the beginning and it'* quite a difference.

You mention doing this around Decemeber.. I am assuming a cooler climate as I am typing and can't see where you are. There'* very little KR at 0F You will need to rescan as it warms up in the spring.

The 3.4 pulley should give you 30 hp and 50 ft-lbs of torque. Torque is what you will feel.

So this is just at the crank right? I mean I have very similar to chrlotte

Also going to install the 3.4 pulley and 604 plugs later on.

Has anyone got a wheel HP and TQ rating?

Also what do SSEi'* Dyno @ stock?

Let me just say that the difference between the 3.8 stock pulley and the 3.4 is two black stripes from any speed less than 20 mph as opposed to just from a standstill.
