02 Maggied TA Got the TA back from getting a new clutch and more tunning and was amazed to see it pute down 473hp and 453tq. It's still completely stock except for the blower( no headers,stock y-pipe, stock internals). I have a print out of the dyno but no scanner, any ideas on how to get it up here?

Before I got I scanner I took a digital pic of my dyno printout and posted it that way, looked OK.

Do no not waste money on springs unless you are doing a cam swap.

The boost will have effect on valve control. It wont "force the valve open" but it will be added force that the valve spring will have to deal with.
just say for a 2.02" valve, the area is about 3.2 in^2
If you're running say 8 pounds of boost, that's 3.2*8 = 25.6 extra pounds of force against the valve when it's shut. Obviously this will be a lower amount of force when the valve is opening/shutting, but for cars on the edge of valvetrain control, its a good idea to have better springs.

That is assuming the valve is completely closed. When open it is obviously bleeding into the cylinder so you are nowhere near that 25.6pounds (which would be even less since you have to consider area taken away by the stem[probably 20% or so]), and the spring is over 100psi at closed and exponentially higher at lift. Better springs are good when the cam is more aggressive. But until then, the stockers will do.
