step. 6) profit!!!

 

do any of you fools have an spl meter i could borrow for a few days?

if not, i'll head over to radio****shack and pick one up.

 

mikie i didnt realize it but there is a much better radioshack not far from us in ashland. just follow 126 south.

the last one is interesting... they talk about a variable compression ratio system... never heard of that before. i wonder how they change the compression ratio dynamically

 

by adjusting cam timing you change the dynamic compression of the motor. if you allow air to escape by opening the intake valve during the compression stroke, you lower compression. if you ensure the valve is closed during the entire stroke, you maximize compression.

that's why variable valve timing is a PITA to tune correctly. it's a balance of ensuring your properly evacuate the burned gasses and fill the cylinder with fresh air vs maximizing the dynamic compression of the motor.

fun stuff since neither one of them can be directly measured.....

 

dammit you beat me to it. You explained it better then me anyway.

 

that's okay. you ruined a nesic dyno day thread better than me.

maybe we should start a thread on nasioc and use the 'google ads- go away' method of getting points.....

 

that's pretty gay that VW is not bringing the the scirocco to the US.
I want one so bad

US $ FTL!!!

 

no rushing it. the block has been smoothed out and cleaned.
the motor didnt blow the headgasket from rushing it. We think it was a mixture of too much timing, a little increase in boost, and possible mix of a little pump gas left in the tank...

we are going to back the timing down in the peak torque area and keep the boost at 33-34 for now.
The car will have some weight out if it, plus 90lbs of rotating weight out of it so we should go just as fast with less boost

 

Less boost?! Just dont turn your back to me at the track, that is all i am saying.

 

 

I think vegas needs a new avatar.
