Don't dump any money into your 10 bolt. I have a friend that fully built one complete with a girdle cover and welded tubes and snapped one of the axles like a toothpick with an na 408 without even putting it on the trans brake.

It's kinda like me wanting to put a pro 5.0 shifter in my t5 knowing it's not gonna hold either way.

A mini-spool is only like $10. The way I drive the car right now, I don't think I'll ever break the 10-bolt and therefore just never upgrade. No launch = no fun. If I break it, I break it.

So for 10 dollars what exactly does said mini spool do?

Is yours a one wheel peel? I forget that's a thing since mine is a y87 with the g80 "locker". It won't do a burnout for anything with the 3.23s unless I dump the clutch and give it the beans in 2nd but even stock with the 3.42s the parts car never had a problem holding the brakes and letting em rip.

Launch. Mine is an open and no matter how careful I am, the car either spins a tire or bogs. I should have the traction with decent 275s and the torque arm. I just need power to both wheels!

It seems that nobody actually makes a drop in mini spools anyway. I forgot that this thing has C-clips so you have to do an eliminator kit. :( I'm not below a Lincoln Locker but I'm not sure that I want to go through all the cleaning and risk of getting spatter where I don't want it. Idk. We'll see.

Just get a diff out of an ss or y87 car if that's all your really after and your trying to keep it cheap. Im not sure what gear set you have but hopefully at least the 3.23s and I'd still go deeper if I was tearing into it.
Changing a 10 bolt for a 10 bolt is WAY too much work and way too expensive. Mini spool is not really getting into it imo. You can do it all that without removing the gearset.

You really don't want to go deeper on a 7.5. That's part of their problem besides flex. The tooth engagement is hot garbage when you get high numerical.

The test drive went pretty shitty. Something isn't working right. With the all the settings in a place that make sense to me, the electric boost controller is not helping a damn thing. In fact, I actually have less boost than the wastegate spring pressure. 5 psi. This doesn't make sense. I'm going to replumb everything to just work off gate pressure. If that puts me back to 8 psi then I know that something is wrong with the boost controller.

Iirc getting the vacuum lines right is critical and was kind of a pain. It always worked perfectly once I got it right and if it isn't working out for you I'll buy it back for sure lol.

I know the settings can be a pain too and I can't remember what exactly it was I had to do to get it to work right on mine or I'd tell you. Could be buried back deep in my thread but idk.

As for the 10 bolt I'm still gonna swap my 3.42 rear into my car one of these days but that's just because it's already here and won't cost me anything but time. I think the real way to go is to put a built 9 inch in it according to my ls friends since they break 8.8s too. Where you've already put a tkx in it and have big HP plans down the road you may as well start looking for one in the junkyard or just weld your spiders in the meantime if traction means more to you than turning lol. But then again you do have a lot of other things to focus on in life so I say run it til it breaks. One wheel peel is probably saving you anyway and it kinda sucks not being able to just mash the gas and do a burnout.

I was walking by the car just to grab a screwdriver and a happened to see the problem. I don't know how I missed it, but at least my theories about the narrowbands vs wideband turned out to be correct.

I had a feeling this would become an issue. The turbo is not supported by anything except the passenger side manifold and I really don't have a great place to brace it.

I'd say that this is enough of an issue to park the car for a while. I'm not going to bother pulling this off and unwrapping just to band aid it with a weld. The nursery is done, but wife has been way more patient with the cars than she needed to be. With Nats behind me and no event goals for the foreseeable future, I'm at a good stopping point for this car.
