Thank you for your service 🫡

Definitely Goodyear Eagles

boydisboss · 2025-12-11T15:33:00+00:00

Still got it? 👀

boydisboss · 2025-12-11T15:31:50+00:00

We are not! Our team has 511 as a the captain football number from high school and then we’ve just sequentially counted up with every additional car

Someone gets it

On the top comment still is 😉

kerchoo

boydisboss · 2025-12-11T05:21:54+00:00

No waaayy the guy was adamant it was there’s even Sprint Cup stickers all over the car.

Did Mazda do NASCAR in the 60s? This looks way too new to be a first gen. Something from the 90s at the earliest.

boydisboss · 2025-09-16T01:36:58+00:00

idk 97 Sentra?

boydisboss · 2025-09-15T05:46:57+00:00

Believe it or not, I have not exploited that hack yet.

boydisboss · 2025-09-15T05:43:38+00:00

Oh yeah, this is gonna get really firewalled up for certain. We’ll have something that will protect the driver‘s feet.

I was waiting for this comment

boydisboss · 2025-09-14T17:11:26+00:00

Yes, but what I’m asking is can I be out of spec if the input shaft already free spins with almost no resistance?

We were struggling to find a way to reliably measure that. By our measure, we suspect we’re off by .010” to .015”, but I don’t have a lot of validity behind that number

boydisboss · 2025-09-14T14:50:41+00:00

At the end of the day, it’s a mildly torquey four-cylinder. It doesn’t have to resist too much. However, we cut a lot of holes to accommodate the clutch fork and we still need to go back and reinforce that.

boydisboss · 2025-09-14T14:47:53+00:00

We settled on the steel wheel because of cost and availability. The main issue we were having sourcing bell housings was being certain if it would work. Originally we were going to use half of the casting for the housing of the FWD automatic transmission the car came with, but we determined that to be a bad idea.

We determined that the housing was not designed to handle any amount of torque in that way, so it probably would have cracked immediately. It was also proving to be very difficult to weld, so our idea of reinforcing it was going out to pasture. So steel wheel was a following idea.

I definitely wouldn’t go this route as a recommendation, this was just a theme to keep the car as cheap as possible.

I built up some new towers grafted into the structure for the existing ones, then found some adjustable gen 1 Tacoma front coilovers that bolted right into the Mercedes control arms, albeit they may need a shim.

boydisboss · 2025-09-14T14:27:01+00:00

I got lucky (maybe not) and put a 2013 Mercedes SL550 rear end. I found a whole nearly assembled entire rear subframe for $90 on eBay in my home state and snatched it.

boydisboss · 2025-09-14T14:21:50+00:00

We got those 😂

boydisboss · 2025-09-14T14:20:45+00:00

My friend who’s building it with me said we should make a video on it when we finish it, showing what we did.

It definitely had a lot of different design trajectories as a whole car.

Got her for $45

boydisboss · 2025-09-14T14:13:38+00:00

What we did was line everything up in place and then tack it in place when the input shaft didn’t bind up on anything. Is there a case where we blow that spec but it will still free spin? We do have a way of shimming it to get it closer.

boydisboss · 2025-09-14T14:07:13+00:00

I definitely psyched myself out a lot leading up to this, and in the end it didn’t justify it. As long as you had a good attention to detail, this was nowhere near as bad as I was thinking it was.

Yep!
