The Questionable Garage is doing a Demon build for all 3 of Holley's Grand Champion challenges using 3 different motors (Hemi, LS, Coyote) but the same car. Pretty cool idea, I like it.
He is using a QA1 coil over conversion kit, which completely makes sense to me with his 3 motor criteria.
What I am curious about is it in the first video (above) he makes the comment that the TB suspension is lacking in adjustment. I asked in the comments what it was missing in the way of adjustment and his answer was; "You can change ride height with the spring preload but you also end up loosing some spring preload to achieve that, so you can make quick changes but you can dial in a coil over way better".
Not questioning his use of a coil over kit, just (apparently) not understanding how coil over pre-load works. I did read one article on it and it sounds to me like tensioning the torsion bar when the suspension is on the stops is the same deal. And the only issue would be if the TB is too strong and/or the car too low resulting in the TB losing all tension when the suspension droops.
And the only reason to preload the spring is to make sure the spring doesn't move off it's seat at full extension, right? So no real handling benefits?
Am I missing something?
And just to be clear, I'm not poking at Jerad, just making sure I'm not missing something.
I haven't watched his video. However, I had this exact same idea last year at Moparty when one guy showed up to three grand champion events and won all three. He owns a vette, and he borrowed a mustang and a viper. When I was there, I told my friend (crew chief) that we need to build a foxbody that can accept all 3 engine platforms. I would build it so the engine was an easy swap with connectors for the harnesses and exhaust with v-bands. While I do think it will be fun, I don't have the funds for such a task. The cost to this guy will likely be nothing since I'm sure he's getting sponsored parts, and his youtube revenue will pay for the car. After all, this is his job.
I hope he gets it done in time for next month. Would love to see another A body out there with us beating our **** like it owes us money.
