I'm still hoping someone posts some before and after engine or chassis dyno data on carb vs TBFI, carb vs Port FI, or TBFI vs Port FI....
I looked a while ago and couldn't find anything, let alone on a Mopar.
If you're thinking EFI will give you more HP, think again. The theory has been proven many times. At the end of the day, a properly tuned EFI system vs. a properly tuned carb, should result in very similar HP levels. Don't forget an engine is an air pump. You can jamb as much air and fuel (N/A of course) and it is only volumetrically efficient enough to make a certain power level regardless of what component is putting said air and fuel into it.
The biggest benfits I've seen on my car is driveability. The coolant temperature control is amazing. I was never able to controlled engine temperature before. I've sat in traffic and it will never get over 195 when it's 98 degrees outside. This is on a 408ci, aluminum head, roller cam, motor with nearly 10:1 compression. What comes with high temperature, vapor lock. No problem there anymore either. It's gotten a little cooler around here lately. Over the weekend, I simply reached in the window and hit the key. It started right up. None of this jockeying the throttle to get the old cold-natured mopar to stay running. Oh one last thing. I had to stop abruptly this weekend for a red light. With a carb, I think we all know what happens 7 out 10 times when you do that, the engine dies. It kept running like nothing happened.
