Looking at the part it seems that it was first cast from a mold with a block of raw material left in order to machine the spindle shaft and flat mounting surfaces from that.
What with all the aluminum cast spindles and A-arms/wishbone set ups in today's cars, I would have thought that the original Trick Titanium facility back during the hey day could have cast it and machined it out of the Ti stuff. They probably did for the late Don Carlton and the boys for sure.
I know of certain carbon fiber brake disc equipped cars out there.
Mu$t be E$$$pensive.
Formula 1 territory.
By the way, there are some subtle but unique ideas in those Formula One magazines. I peep 'em all. Talk about high end Titanium companies peppered around the UK.

People only see clearly what they think they know about. LOL.
By the way, way to go on your recent middle to low 11's. A little more tweaking and the tracks are going to show you the door unless you rollbar it.
Bottom 11's should not be that far off. Very nice car.

Thanks!

11.30 @ 121 mph so far. They hunted me down in the staging lanes and slapped my hand last time. LOL!

More than enough to whip those pesky Vipers and Hellcats on the street. I drive it A LOT and it's comfortable and quiet. I really look forward to finishing the paint and installing trim.

Trim's too heavy. LOL

Was in conversation with a buddy of mine who works the armored car shift and he jokingly asked me the challenge of lightening his 5 Ton rolling Fort Knox and I Henny Youngmanly said to him: "Accidentally dropping all those canvas bags out the back door would be a good start. LOL.

good one ! next question, did he bite, and where did you "stash the cash" ?

I'm still tailing him like a stock car wind cutting.LOL.

Bumped into some of my notes tonight and took note to the weights for typical front runner tires. I used to run the very popular and yet vintage Formula 1 Super stock tires back in the day and then the Moroso Drag Specials before that. Now I have the Coker pie crust tires for more stable sidewalls.

Weights were/are as follows:

* Formula 1 Super Stock - 23 Lbs each.

* Moroso Drag specials - 13-1/2 lbs each.

* Coker Pie crust skinnies - 19 lbs each.

I've never run the DS2's from Moroso, but they were super light and yet iffy in my book for the street.

I do wish some company would rerun and release those Formula 1 tires. I'd run them again just for the looks. Would have to run helium in them though to make up for the weights. LOL.

What about these??

Never weighed those ET's but I presume that they are in the weight ball park of the Moroso's or maybe just a tad heavier since they look to have a more thicker skin sidewall.
I'm also concerned about thread design and tend to lean more towards the jagged pattern like the Morosos and Formulas for more stable contact patch.
I also remember using the Pro-trac front runners and they were great but a little heavier, again because of the sidewall design which is more resistant to rolling or folding and tearing on the street.
I can't believe that people got away with Volkswagon tires for all those years going fast MPH. Of course today's MPH numbers are insane even on the 1/8.

One lightweight knowing another. It takes one to flow with one.

Lot of pics of the back of that car driving around Frushing. Cool to see those two cars on the prowl in broad daylight, must have been quite a sight!

Quick update on my Duster. Received my aluminum gas tank last week, nice piece! The tank is fully TIG welded all around, it's like a work of art.


Though the OE tank is not super heavy, you can really tell the difference with the aluminum one.


It's kind of stealthy I guess. The sump gives it away but its not something you would notice at first glance unless you think to look under the rear. If anything, someone might think it's a fuel cell sump sticking through the floor.

Managed to take some time to get it installed today. Finishing up the new fuel lines at the moment.

You know how it is when you post a picture of what you are working on at the moment and everyone notices other things besides the main subject. LOL

What are those clamps on the rear springs set up like?
Is that a Cal-trac system?
Meanwhile, back to the original posted flicks. That tank looks fantastic though I was under the impression that you also had an in tank pick up/pump. Forgot you mentioned the up front engine mounted pump.
Stealth.
I like the fact that your set up utilizes two mounting straps and two J bolts out back. Mine only has one and I've been meaning to make a custom fail-safe system to keep my tank in the car just in case.
Yeah, those tanks are pricey, but worth all their lightweight in function and good looks.
What was the weight difference again?

Yes, they are Caltracs. Split monos, aluminum spring eyes, Rancho/Calvert adjustable shocks, the whole 9. Plus, I used Dr. Diff offset spring hangers - WAY nicer and WAY lighter than the old MP bricks.



Yep, just a mechanical pump and a fuel tank. I thought about an electric though, believe me, it was a hard decision not to get one. Still up in the air as to whether I made the right choice. If/when I do go with an electric it will be in tank fo sho.



It's tight. I used some neoprene tool box liner between the top of the tank and the body. I put some of it on top of the straps as a cushion to keep the aluminum from getting gouged over time.



Yeah, they are nice but I am still unsure whether the money would have been better spent elsewhere. It's a tough call, again, most would probably just opt for a cell over a tank if there was any extra work or cost involved.


8 lbs. You can feel it, it's really light.

Trust me, a cell is nothing but a burden in a real street car.
The trunk is nice to have bare.
8 Lbs is a good amount.
I did the same with cushion between the tank and strap to prevent gouging and or rub break.

Here comes the moon.

Little hard to have the stock fuel filler when a parachute is reqired,,,

Yes it is. You will have to really think it through as that's. the cost of going really fast.
I would think that you could mount the shoot just below the plate door. I would look at some fast cars this Summer. Lots to view at the Nats this August. Hint.

I can tell you right now I would take a trunk floor over my fuel cell anyday. The only benefit to a cell is it not being in the way while down there working past that it is a major PITA. Dzus fastenered trunk lid sure doesn't help either.

Fully agree! I just fabbed a ~22 gallon cell that is sectioned into the trunk...still no trunk space between tubs, battery and cell...

Next car will have factory style tank for sure!

A fuel cell has it's place for sure but sounds like I made an OK choice on the tank. Even have the trunk board in. No spare though! Would like to find a decent repro trunk mat, last one I got wasn't even remotely close to the original.
