I run a standard port window SR (they are MCH ported) on my 511. Car is 4g with me in it. 4.10 gear. Could it be faster with a MW port? Possibly. I don’t really want to go there though. It’s a heavy street Car that gets driven everywhere from work to the track. The standard port window allows me some intake choice. I sometimes run a TM6 with a 1050/4150 in place of the six pack. Both combos ran identical, best et to date is 10.92 running through mufflers, air cleaner, driving it to the track. I shift it around 6g and it’s happy as can be. It’s super torque’y and responsive. Drags that ole rr around like it’s a gutted A body. And I’m sure it has more ET left in it if I wanted to chase it. It’s a 13 sec chassis with 10 sec power.

A 4-speed with a 2.65 first and a 3.54 gear is gonna need instant torque and response in a 4g charger. I think the TF240 would be a proper fit also.
