I tried calling them, but wow...I was on hold for a while.
But anywho.
I bought the disc set and have no idea which is which.
Im thinking its bys ize, but a couple of them are the same size.
Any easy way to figure out which disc is which?

 

see archives.....or the instructions that came with the discs.


2.72" Dia for the 12:1
2.47" Dia for the 10:1
2.22 Dia for the 8:1
1.85" Dia for the 6:1
1.59" Dia for the 4:1

 

Damn BRAIN!!!! Finally a question i knew the answer to and you beat me to it!!!!!!!!! AHAHAHAAHAHA :gay:

 

In that case.
There was a 6:1 Disc in it already
Haha.

 

Interesting. You should be running pretty close to where you want to be then in terms of fuel with the 1.8 injectors and the 190hp pump.

 

did you buy mine? i cant remember who i sold it to... it had a 6:1 in it if so.

 

Nope. I didnt buy yours Scott. It came with the Greddy kit when I got it.

 

then it should be a 12:1....with no spacer/holder thingy and completely fill the interior diameter.

 

I bought it used.
So, the PO must have put it in.

 

aiight tough guy!

 

That might have caused some problems if you assumed it was a 12:1 disc in there.

 

Actually.....
Now that I think about it.
I was detonating pretty bad at like 5psi on my non intercooled set up with stock fuel pump

 

Sounds about right.

Now I feel like checking the size of my disc.
