PM me with your e-mail and I can scan and send you a drawing. I would have the washer made in tool steel. If you hook up with a shop that can make you 5-6 of them, I think you could sell them on here. I have some L9 bolts. Once I know a length, I can probably fix you up. The washer will be specifically to fit a RCD hub. If you get a different hub, you will have to dimension the washer accordingly. This set-up had been very reliable for us. 14-71 blower@ 35 PSI.

Got it fixed and 220 lbs of torque on an L9 bolt...



I originally built this engine in 2007 and at the time it had 10.25/1 compression and it was naturally aspirated. It has a small solid roller with lift numbers in the 5’s, 250 @ .050 and 110 LS. It made 550/550 on the dyno and was a fun little motor. I bought the blower setup shortly thereafter and have had it on this block a couple times in the past with the high compression.



I decided to lower the compression so I could run pump gas so I lowered it to 8.4/1 with new pistons. I have been driving it around for over 2 years now and then the snafu this thread is about happened. I had never dyno tested it with the blower so we decided to do it after the crank was fixed. They put it on as I had it setup and it made 710 HP but was pig fat. They dropped the jets in both carbs 6 numbers and it responded with 751 HP @ 5800 RPM 5% underdriven and 11 psi. On the dyno we had the alternator on it because the belt runs the water pump and we left the blower scoop on it. Plugs look great and it starts like it’s fuel injected.



I also have nitrous on it to cool it but didn’t dyno it that way so the 150 I hit it with while Mexico racing should really wake it up. They made the pulls at 28 degrees of timing and I pull more with a boost retard box when I am spraying.



Can hardly wait to get it to a track with 40 more Hp and 50 more FP of torque and a brand new converter that maybe my heavy pig won’t drive through...

Looks good, lots of power. The blower pulley does stick out way farther than ours. The extra clamp load on the bolt will help for sure.

The things we have to do to use factory water pump and alternator...
