Plastic Fantastic 76 Corvette

time to cap

key here is to not go fast


and be clean

hopefully crack checking tomorrow night

[SuperBuickGuy]

onward

welded 1/2 last night, other half tonight - and did it over a couple hours so I didn't get warping


pretty welds leak. My goal here was full penetration - thus the weld has some grey in it - key here is the HAZ is even (heat affected zone)

and all those black marks are holes - to check for leaks - I look for holes or HAZ changes

for whatever reason, this side didn't have any

then I put 7 or 8 psi in the tank, spray soapy water on the seams and blow bubbles

hmmm more bubbles

leaks fixed, clean up the tank.... next up, removal of the old tank eventually this will have tabs on the bottom so I can attach a defuser and also attach the rear panel to it

[SuperBuickGuy]

time to test fit

old tank

and out

get the fuel out... was joking with my dad that between the fuel in the tank and the nickel in the tank I should be concerned they'll both disappear

now you can see what the plan was

even got pretty close lining up the fill spout - the plan all along was an offset then straight into a coupling and the filler

[SuperBuickGuy]

tonight started mapping how I'm going to accomplish the tasks

was kind of hoping there would be some 'dos' and 'dont's' from the seller... guess not - this needs to attach to the deck and be supported underneath to the frame

here

the optima battery is 1" wider... so new battery box coming


part of tonight was a failed attempt to figure out whether the wire with a knot or the brown wire were the reverse light wires... I have a schematic - but who knows where


tomorrow I will spend some time on this but most of the day will be spent looking for used parts that I don't need....

[SuperBuickGuy]

Battery, cont.

it's like 1" wider... so a new tray is in order

and off

new tray

and installed and painted

at the swap meet today, I took a chance on several of these...

makes getting the burn off a lot easier

and reverse light....

[SuperBuickGuy]

time to give it wings.. or a wing

aluminum angle



some solid eyeball calibrating followed by serious staring





wing held on by hopes and prayers with an assist by gravity





it's about here I'm considering whether or not I like the stands.... they need to parallel something, e.g. the rear valence and let me be SUPER clear, I approved the design. CIRO did what I asked them to do...



my brave act of the night



now in place





thankfully, I have a plasma table... basically the wing will end above the end of the deck - so it will move horizontally.... no big deal



love it





a good view - the stands will mirror the rear angle - also, I have to build an 8" version for Optima.



paint is dry so I can finish this as well

[SuperBuickGuy]

I rarely ask opinions - mostly because they're someone else's preference (which is fine, and I have my own).

But here, I'm kind of stumped.

the angle


do I match the B pillar window frame or the tail light panel with the struts?

[SuperBuickGuy]

onward with fastening

Luigi is checking out the progress too

notice the tail blur? he is one active dog (love it)

bolted down

with pads to pretend we're saving the paint

and tied to the frame

tomorrow weld

[Panteracer]

I like the struts layed back a little so matching the
back of the car. I have changed the ends on mine
multiple times... Starting to rework the ones on my
Gt-1 race car plus raising the wing some

choices.
The A1000 pump is good for 1200 hp and has -12 lines in and out. The Holley system right now has - 6 lines and makes 500 wheel hp
I've been going back and forth about upgrading lines. I have most of what I need to upgrade to -10 supply and -8 return.
But
at this point I'm already pushing noise limits and 700 hp is at 7000 rpm. As it is now, it's got a physical cap on noise - set the rev limiter to 5500 and life is fine.
But yeah.

my only real concern if I leave it all -6 is it puts a lot of stress on the pump but with that said, I can turn the pressure up to 75 psi if I really want more power... after all volume is a function of pressure

got more done tonight, though.... think I'll stay with -6 for now.... but when I build more power, I'll update. At this moment, the car is fast enough for my skills.
line test

starting to lay out how the tank will be mounted

I also need to put an offset in the fill tube to line up with the gas cap (3 7/8 offset)


I also welded in the braces - brackets got a coat of paint so drying... bolts get here Friday
