sweet, thanks zeadlots

Re:Compression on D before turbo
 

Mine was STOCK D16a6 at 205, 205, 205, 205 before turbo + can of restore at 176k miles.

1 year later (over 10k miles) of experimental boost, it's now at 150, 150, 150, 150. I was pretty stupid even though I had a safe setup because my dist timing was off and I was getting detonation that I didn't know about for 1 year even though I had turboedit tunned good. I think my motor had a little carbon buildup (explains the high numbers), but now it's lower because I'm spraying with water inj.

Re:Compression on D before turbo
 

whats the compression ratio on the a6?

how much boost were you running? and what i really wanna know, is how did you NOT know you were detonating?

Re:Compression on D before turbo
 

d16a6 c/r is 9.1:1 i believe.

Re:Compression on D before turbo
 

wow 205 is nuts high for 9.1

Re:Compression on D before turbo
 

Well here is is:

Car had 204,000km's I just had a 16 hour road trip so there is going to be no carbon.

155,150,160,165

Re:Compression on D before turbo
 

My exhaust was loud and I never would have heard it. After I rigged a 2.5" muffled exhaust I could hear detonation and I soon tunned it properly.

Re:Compression on D before turbo
 

woo wooo!

Well, i just did another compression check on my own car, now since the weather is nice, and i am at lower altitude, and heres what i got:

190 190 191 191

I think i am ------- set to go for turbo. Those are damn good numbers.
