Oldest (possibly slowest) to newest (possibly fastest) HO chassis?

[Monty]

I've been away from HO racing for a couple decades now but I occasionally check out some YouTube videos and eBay listings just to see what's out there.  

Growing up, I was aware of the Aurora Vibrators series, but never owned any as the T-Jets had replaced them by the time I started.  At some point ('71?) Aurora came out with the slightly larger-bodies A/FXs, while Tyco had the Tyco II (2-button pickup) chassis.  Aurora's Magna-Traction cars were my favorites (fast and easy to work on) while the G-Plus cars (late '70s?) were a whole 'nuther level of fast, but not as easy to work on.  I don't know the specific timelines but Tyco had the HP7 and 440X2s out, and they seemed to run decently, but after buying a Marchon set, racing was almost boring (tons of speed, perfect magnets - never lift).  Shortly after, I kinda dropped the hobby and pursued my 1:1 car interests.

I see now there are replica T-Jet chassis (with or without a traction magnet) X-traction cars (Magna-Traction twins that are slightly less powerful), Super G-Plus, Mega G-Plus, Wizard, Bulldog (best?) and probably a dozen more I haven't heard of. 

How would you rate the various chassis that existed and/or now exist?

IMO, its hard to beat Wizzards, but  Vipers will put up a good fight.   As far as "factory" goes, (tyco Afx etc) they are pretty lame without  major modifications.

I guess I see the list I'm looking for as being similar to 1:1 hot rodding, which more or less started off with people modifying flathead engines up to the point where American car companies started offering OHV engines.  Now, if I understand it correctly, you can buy 1,000 hp cars ("Corvette and Mopar) off the showroom floor.

Yeah, T-Jets weren't the fastest HO cars ever, but what, at the time, was faster?  Maybe a Tyco with better rear tires?   Just like the original small block Chevy, Aurora Magna-Traction cars could be "rodded" (properly matched and shimmed magnets, better armature etc) to absolutely fly, but just like the 1:1 cars (LS V8 engines), better things evolved.  

My knowledge of the hierarchy drops off after the late '70s and the advent of the first series of G-Plus cars.  I guess I'm wondering if anyone knows the stairsteps from that point to Wizzards.

Here's my dated prototype A/FX from 1970.... I have a '71 also...

I've been experimenting with Round2 slot car chassis for some model railroad projects.  🙂
