2019 Challenger Widebooty HellKitty (she's giving me the meatsweats...)

[L92 OLDS]

Will you take it to the track yet this fall? I'd like to see your numbers.

That's the one. The close ratio is awesome, and kind of un-nerving - I caught myself putzing along in 4th when I should have been in 5th on the way home. I also spend a lot of time going 3-4-3-4-3-4 as either one feels right with the amount of torque it has. The car kind of begs for 4.10s or better (factory is 3.70s) - even if it will go 100km/h in first. I love not having the .50 6th gear too.

Funny thing is that while the transmission is rated at 650ft/lbs input, the car is rated at 656ft/lbs now. Pretty sure it has a solid 10% fudge factor built in.

Wow! That's a tall first gear (eye of the beholder). The T56 Magnum ('aftermarket' TR-6060) in the Camaro has this set...2.66, 1.78, 1.30, 1.00, 0.80, 0.63

We're running it with a 3.42 and it is pretty fun. The rear gear set went in the car when we were going to go back with the SBC/TH350. If I had it to do over again, I'd go with a 3.73 to make 6th a little more useable and 1st gear even more fun but as it is, the car is too snappy in 1st gear for 99% of traffic on the road. With the torque your car has, I'm sure that 2.26 1st gear feels like granny gear. It sort of reminds me of the really expensive cars in the 20's and early 30's that had V12's and V16's. The big idea was to have enough torque that you didn't have to shift. You just ran around in high gear all the time.

I don't have a tall 1st gear in my T5 WC but then I don't need it with the engine plus all the stickers on the GP.....

First and second gear are enough to get me in a lot of hot water.

It feels a lot like the econo-spec WC T5 I had in my '91 Z28. The worked over TPI 305 had torque for days.

This picture is very Yin and Yang.

Car/truck, stick/auto, RWD/AWD, white/black, Dodge/Chevy, no options/fully loaded, two doors/more doors, cloth/leather, fair weather/bad weather, two scoops/no scoops, etcetera etcetera.

About the only thing they have in common are their supercharged 6L+ V8 power plants - totalling almost 1400hp; and both scare the sh*t out me.

That's mild compaired to my Saginaw's 3.11 first gear.

That's mild compaired to my Saginaw's 3.11 first gear.

When I say tall I mean high (numerically high). A low (numerically high gear) I call steep. 1st gear in my WC T5 is nearly 3:1 as well. Steeper than I'd like but will pair well with the 3.08 in the rear end. Oops....

It's going to suck having to put a big ugly licence plate on the front of the Hellcat....

No it won't: https://www.summitracing.com/parts/bmp-sns1e/

Plus, half the cars up here have no front plate - thanks Quebec!

I hope you can get away with no plate, it'll take away from the mean front end look of the car....
