  Please explain

[BigMike]

Isn't that your new gas tank?



If so then its right above the rear cv/ujoint. If the joint blows then the driveline could wack through the body and smack the tank, and with some sparks you could roast a couple marshmellows

if thats actually a real concern, but some sort of driveline safety cage might be a good

[Willy Mammoth]

Have you been taking pain killers again? The fuel tank is inside the body and the floor is 16 gauge. If the drive shaft was to rupture the fuel tank it wouldn't do much except make an oily mess. I have never seen diesel blow up into flames like gasoline.

[Willy Mammoth]

I was thinking about welding in a 11 gauge stainless gaurd to help protect it further. Have you ever tryied to cut 11 gauge stainless steel?

BigMike isn't thinking straight lately.  Its kinda my fault- he's got visions of positive manifold pressure in his head...

Yea I remmember those days. I mean the days of playing with turbos. How does 25psi of boost sound on a 76 280z. I will have to find my videos of me drag racing and link it here. 12.7 at 110 mph in the qtr mile.


I think he is just in shock after his spill.

Mike, take care of that knee and lay off the pain killers. 

[BigMike]

Yeah I didnt really consider the fact that the Mammoth is runing on diesel. Pain Killers? I'm to busy waiting for Ryan to hook me up!

[reklund5]

patience, grasshopper.

I run 24 psi in my Supra...


Ryan

[scheid6996]

Here are some links to a few video clips of the Z drag racing. Keep in mind that they where back around 1991.

http://www.mhdfl.com/Videos/Mark's%20Z%20Racing%2004.wmv  This one was an RX7 that just didn't have any power like most.

oh nice, slacking off while I'm still hard at work and you're not even on-topic! OK so maybe it is your thread but you're still slacking off. 

[Willy Mammoth]

So how does it feel to be working when your other is slacking off?

I guess payback a biatch

You talk about transferring fuel over the hump in the tank, how are you going to do that?  Two pumps? It seems that once the fuel gets down to the hump it will only get fuel from the side the pickup is on.

Nice project BTW.

Looks good Willy, like the paint

I cut out the last 6" of the tunnel so the floor will be flat back there and I am reshaping the bottom of the tank so it is the same. This will allow for fuel to drain equally. I am also putting a drop in the bottom of the tank that goes through the floor where I will pickup the fuel. This will make sure the pump and engine have a source of fuel when it is at a severe angel.

Do you think you will ever get that low with a diesel?

[Lady Di]

Do you think you will ever get that low with a diesel?

depends on how far we go. 

[Willy Mammoth]

I don't plan to run it low, but I am more worried about air getting into the lines and causing it to run bad or stall at a time when I need it most.

I also plan to build a purge tank like they use on airplanes to allow for good fuel flow at any angel including upside down.

[UNBREAKABLE]

thats a good idea

[Willy Mammoth]

Better stop shaking it like that or it might go off.

[Uncle Jesse]

Thanks, the first picture of the tank doesn't show a flat all the way across, that had me scratching my head.  Now it all makes sense.

It wasn't flat. That was a  . But don't tell Mr Willy I told you that!

More pics of the rig please!!!

How do you shorten your shafts? I knew someone a long time ago who made a special input shaft for a gearbox out of two shafts grafted together, one was tapered on the outside, with a straight end that was threadedand the other was bored withe same taper, drilled and threaded. the two were screwed together a v was turned where the two met and they were then welded together. This was a rover / Buick v8 mated to a jaguar gearbox! I am interested in your machine shop methods, modifications and alignment as I am building up a home machine shop/ foundry so any techniques, methods or usefull tricks are really interesting to me.
