Hey Mo, any updates?

I love this project and I'm hoping you have some new goodies to share

Mo_Bandy

Hey there!

Thanks!
Unfortunately not really much happening.

I’ve been super busy with other things going on, but the Vette is still going well and strong 😊

Thanks for checking in though…

best regards,
Mo

This Saturday, cars and coffee at Toledo Executive (NOT express) airport hosted by the EAA, awesome
event…cars mixed in with very cool old planes that fly in. Your drive onto the tarmac. It’s “invite only” since it is at an airport, and I’m inviting you ! Let me know if you want details.

Thank you for the invite, unfortunately my daughter just moved here from CA and we are having a house warming for her this Saturday. Perhaps the next time 😊

Best regards,
Mo

Hey Mo/Wayne,

I came across your interview at with Internal Combustion’s Youtube channel. Ive been pipe dreaming about doing an EV conversion for a while and your idea coupling Hyper 9s really blew my mind. Im not a fan of starting my first build trying to jerry rig a hacked Tesla rear end like Damien McGuire does, at least not until Im more experienced.

I was curious about your use of Torque Trends TorqueBox (1.9 reduction) coupled to a 2.59 diff. Did you consider going direct to the differential and swapping in a higher ratio ring and pinion like a 4.88 or something that gets you to the 5:1 ish ratio?

Reason I ask is Im floating that idea in my research as a way to reduce weight and drivetrain losses. My SC300 has a 4.27 which might be a little too sluggish even with 2 or 3 hyper 9s. Trying to see if theres kits out there that can bring it to 5.00 or higher.

Thanks!
Brendon

Hi Brendon,
Yes I chose the Torque Box for a couple reasons.
The Dana 36 rear end about the highest you can go is are 4.11 gears. I was actually running 3.73's when it was supercharged. So I selected the 2.59's to put the motors at about 2000 RPM @ 60 mph with the overall ratio at 4.941. It was more personal preference, the Hyper 9HV's max RPM's are about 7000 rpm's the torque curve starts to fall off at about 4300roms and they are designed to run continuous at 3600 RPM's. So as you can see it's a matter of higher top end speed, or acceleration. Even with the 2.59's I was still faster than a stock Corvette which was 5.7 seconds. I was running 4.8 seconds consistently.I also wasn't worried about overheating the motor running it at a higher RPM.
The Torque Box has a parking pawl which is essentially like putting the car in park, rather than having to set the emergency brake to keep the car from rolling.
Also I felt the Torque Box was more robust in terms of gearing as well as connecting to the rear of the motors and mounting to the frame.
Coming straight off the 1 1/8" shaft that is keyed seemed a bit scary to me as you are counting on the bolts biting into the shaft to keep everything together. Where are the Torque Box coupler and mount are very beefy and also add another mouning point to keep the motors from moving around under acceleration etc.
If you wish to reach out directly my email is wrbickley54@gmail.com

Gosh. I've never seen this thread before. Really interesting project. Mad scientist stuff. Ha.
