G-machine of a different.......scale?!?

So cool and I think you should go Whipple.

That is the way I am leaning. It will save $100-200 in parts cost, between the turbo's (whether I have them printed or make molds of the masters that I created), machined fittings, braided line, etc.

I'll be ordering parts this weekend. I need to go through the resin parts I have for the engine/transmission and see what all I want to use and what I want to replace. I'm hoping to have all of the major engine parts in a couple of weeks so that I can get it assembled and start detailing it.

This project is killer awesome!
PLEASE keep posting!
I too would go whipple

Thanks. It's been going off and on for about a decade. I'm hoping with the new availability of parts, I can keep the momentum going.

The cool thing about those 3D printed parts, the guy that created the LS3 has a full set of internals too. It would make a sweet little diorama. The down side is the cost. The fine detail material gets to be super expensive.

Just curious what would they cost ??

1/8th scale, with the way he has everything listed in his store, about $200 for the parts. This is with the majority of the prints being in material that leaves a lot of texture. This is ok for the block if you are going for a factory cast look. If you want a machined, LSx look, it would need to be printed in the high def material which drastically increases the price. The other parts can be smoothed, though it would take quite a bit of work.

I know he prints 1/4 scale parts, though he prints those in house and I don't have a price on that. I could get a price if you were interested in a scale LSx diorama for a desk piece or something.

Edit: That total cost could probably be reduced if I had him put it into the store as a "kit" with all of the pieces in one file to print, that could reduce the cost.

A few things to try and show the process, and trials this thing has been through.

The over sized wheels I mentioned were going to be SWEET, had they turned out correctly. The centers had the look I was after, though after the sleeves got machined, they turned out to be 23" in scale I think, and once I mocked them up, they were entirely too large.

The process:

I drew up the wheel centers, printed some test pieces, and like the look, though I felt they needed to be a bit bigger, the original spokes were too narrow and I felt the wheel was a tad too small. Upon re-design I printed new pieces and then ended up stalling because I couldn't find anyone to machine the wheel sleeves. I finally came across a group of modellers who had a Facebook group dedicated to big scale modelling (1/16th-1/8th). It was there I got hooked up with a guy who could do what I was looking for. So, I set out to get the wheels finished, one of the major hang ups of this project.

This is how big they turned out:



You can also see here that the guy machined the wheel sleeves for the center to be rear mount, I was looking for front mount, to replicate a 3 piece wheel. They were also machined with a "stepped" lip and I was looking for a smooth transition from the lip to the center. So, we talked it over and I sent them back to have him separate the sleeve and the mounting ring so that I could adjust the centers to the depth and mounting orientation that suited the build.

Here is what I got back:





Unfortunately when doing that, I was left with sleeves that did not have a smooth inner diameter, and mounting rings that did not fit snugly inside of the centers. Leaving me with parts that were all but useless. In the midst of all of that I thought about the lack of tires for the build, and once tires were on it, they wheel/tire combo was going to be ENTIRELY too large and look like a Donk.
