The benefits are that if you are planning on building that motor for more HP, that you can do it cheaper/easier with the carb/no computer controls.

Re: MPI to Carb ??
I'm by far no fuel engineer, but it seems to me that a fuel vapor would be easier to ignite than droplets squirted into the intake.
But I have the feeling it's probably so he doesn't have to be at the mercy of a shop to tune his engine.

Re: MPI to Carb ??
alecsammy, I can sympathize with your desire to consider a carb. I have EFI's and one is problematic. No one can seem to find the problem. Mine have been great for many hours but the lingering problem sometimes makes me wish I had carbs. I love the starting and idle quality and the MPG. But, new carbs set up properly can come real close to EFI performance overall and even exceed top end.
Good luck.

Carb = simplicity, EFI = potential nightmare. Often problems with a carb motor can be diagnosed quickly and easily, with EFI the potential problem list becomes endless. When they run fine EFI is great but when they dont it is a pain. Carbs are much easier to deal with.

EFI in my car is great. But I'm not trying to modify my car. I've read way too many stories of people building EFI, and having to send the computer back 3 and 4 ++ times trying to get it right.

Re: MPI to Carb ??
Saw your post about going to carbs. I'm actually looking to go to MPI from a carb. I'm not looking for the extra HP and want the reliable start and fuel economy. I'd be interested in buying you EFI set up if you're planning on selling. Would you need my intake?
Just thought I'd throw out the food for thought.
