Anyone know what the specs are for the FMU that is sold with the powerdyne kit. I was going to attempt to rebuild mine with the kit Powerdyne sells. It's an adjustable rebuild kit from 8:1 to 10:1. I'm assuming 10:1 supplies more fuel over the 8:1 correct?

I don't know which one you need, but I do know the answer to the ratio numbers...
It's the extra psi added, for each lb of boost.
So the 10:1 will kick the fuel up 10psi for each lb of boost.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a> -
I am running 6:1- the manual says that your fuel should be between 60 and 70 psi at 6 psi of boost.
Seeing as that we idle at 45-50 psi, you need an increase of 10-20 psi over 6 boost psi. Playing it safe on the 70 side, that works out to somewhere between 3:1 and 4:1.
I didnt feel comfortable running 4:1, so I put in a little extra fuel (probably running rich with 6:1)All gone :(<br />Best ET ever: 14.3 (I think)<br />----------------------------<br />Check out my site for exhaust clips, burnouts, and pictures, and the supercharger throttle body mod.<br /><a href=\"http://www.geocities.com/net_addict/index.html\" target=\"_blank\">Click on the Firebird</a>Comment

The 8:1 is the universal one that PD sells. Most us PD owners here probably have this.
The adjustable one, is that from Vortech?

I found a rebuild kit for sale:

I need to rebuild the FMU I have since my A/F ratio was super lean on my recent dyno.
I'm selling this blower to a local 3.8 bud and want to make sure I get the correct ratio installed when I rebuild the FMU.Michael Huff<br />92 RS, 98 V6, 97 SS, 00 Z28 <br /> <a href=\"http://www.carolinafbodyclub.com/\" target=\"_blank\">http://www.carolinafbodyclub.com/</a>Comment
