It's not a bad tranny built right. I mean how much are you going to spend on a good 5 speed? Then you can't do anything else but switch gears while driving.
It's the torque converter - typcially 10% more HP loss, up to 20% HP loss under high RPM, compared with manual transmission. If one gets skilled with shifing manual transmission, it will usually do better than auto trans.
Less consistent though.
When bracket racing it's all about being able to run the same or close times time after time. No stick shift can do that since it's up to the driver.
You get a smaller torque convertor to make it up also a convertor multiplys the torque whereas a stick shift is direct. Get yourself a good $$$ convertor and your on your way.
I am a firm believer that a 5 speed cannot touch an auto tranny for racing. Once the tranny has been built correctly and matched up perfectly to the car.
Where as a 5 speed can be adjusted to any motor by the way of the clutch.

I don't see anything in the description of your engine that would make me feel good about advising you to add nitrous or a supercharger... certainly not a 150 shot!
Before you go messing with power adders, you better make certain your bottom end can handle it. Forged pistons, hardened rods, forged crank, etc. are where the smart people start building an engine, when they intend to use nitrous or s/c.
In that case... you're good to go... Have a blast! You might want to take in in steps though... 50 - 100 - 150, just so you can find weaknesses early on.
If you're running 10:1 compression or more, be very careful with a supercharger or turbocharger, that's really too high for reliable performance with those. But might be really interesting for a little while!
