Hi Greg,
I run about 11-12" of vacuum with this cam. It does not bounce much more than 1" at any time. Although, this is idling at 750 RPM and I would like to idle higher, but my carb likes to drip off the booster with more RPM than that. I think if i idled higher, the vacuum would be almost 12" Is 11" with 1" of bounce enough vacuum?
I am planning a MSD 6AL2 unit with the rev limiter. That is a nice box and should work well.
I am really stuck on the two different systems. I wish there was a clear cut advantage, but i am not finding one.
I have a thought on the tank. I will sketch something up tomorrow and post it. I hate the looks of the rear sumps. They just look odd on a pro-touring car. My idea involves cutting a 12"X12" hole in the top front portion of the tank, making a box that fits in this area with 3 trap doors. One in the back, and one on each side. The idea is that under hard acceleration, gas will force the rear door shut and trap the fuel in the sump. On a hard decel, the fule will open the trap door and fill the sump. Same goes for the side trap doors. A hard right will close the left side trap door and open the right side trap door and vise versa. The top of the box would be welded or soldered to the top of the tank and the pump and the lines would be screwed into the top of the sump box.
Since this is a used tank, i figured that it would be a good place to practice. I just need to get it cleaned out enough to cut and weld on it. Is there any solution that can help with this? i like the dry ice idea. Where can a fella get some of that?
I was going to have the pump draw out of one compartment of the box and have the return dump into another compartment. This will allow me to recess the box down about 1" below the top of the tank so i can get the lines in and out of the top of the sump box. I have -8An aeroquip line running from the rear to the front and i also have the factory 5/16" line that i could use for return. Will that work for this application?.
Thanks for the help. Bob
