Just checked Steve's home page and found series 18. Maybe I'm a little behind but it sure is looking good. Must have been hard to start welding in the roll bar on that nicely painted frame.
A few questions Steve.
I don't understand your fuel system. Do you have a single tank outlet feeding one pump in the bottom, out the top into the top of the second pump and back out the bottom to the engine? These pumps are in series? I thought you would have dual outlets with the pumps in parallel for volume. Also I am suprised that you can reverse the inlet and outlet.
One other thing. The drive shaft. You mentioned solid steel , don't you mean Steel construction. Driveshafts are not made solid.
It is looking good Steve and I am anxious to hear your impressions of how it feels to drive something that powerful.
Have a good day and thanks for the update.

 

Yeah, I saw it too. It's looking good :cool: ! You can tell it's getting close to the final body drop. Steve, you are going to HAVE to bring that thing down to the Cruise-In :cheers: !

It looks to me that the pumps are installed in series from the photo of the pumps on his 18 page. Parallel installation would increase volume but not pressure. Series installation would increase pressure and perhaps that's what was needed to feed this baby.

Maybe his driveshaft was carved from a rectangle of billet steel to provide ballast - kind of a long, thin flywheel... :lol:

 

Hey Norval! I'm about to post series 19. Actually, the frame is powder coated, not painted. Well probably have them touch up the few welds we've done before putting the body back on for good. They are finishing up the final touches on the engine right now. As for the pumps, Z-Man is pretty much right on the money. One pump will flow enough for close to 2,000 HP at very low psi. The problem is when you start increasing the pressure requirements. You are using carbs in your setup, so you can get great volume at 10-20 psi. We need a static 50-60 psi in this thing. That brings the effectiveness of one pump down to around 1,000 HP. Honestly on the street one pump will be more than sufficient, but for all out raging at the salt flats or track, we will need the second pump to keep the pressure and volume at the right levels. Also, the ECM actually regulates the flow for us. At low RPM's only one pump is running & I can toggle that in the cockpit. When the system senses high boost from the blowers, it will turn the second pump on. At that point there will probably be smoke everywhere!! As for the driveshaft, you are correct. I figured most people realized that a driveshaft would weigh about 200 pounds if it was solid. What I meant to say was that it "all" steel, not "solid" steel. In other words, not alloys, no compounds - just steel. Thanks for the clarification...
