5.3 + maggie 122 + 90MM tb = good or not???

Run that 112 at 500whp around a road coarse once lol. One of two things will happen.
One, it runs a incredibly slow considering the 500whp dyno sheet because you have it tuned correctly and its pulling timing when the IAT's are at 200+ degrees.
Two, it melts the engine down because it rattles itself to death.
I can make a 112 hit 500whp on the dyno too after a cool down. Make it repeat itself after 3 back to back pulls like a properly supercharged or turbocharged car and then I will be impressed.

Ok I will see your road course and raise you one smoked porsche. Next?>

Excuse the fact that he smoked a purpose built race car, I am just showing you that the MP112 Magna Charger will and DOES perform on the road course. FYI, that car has over 6000 track miles on it.
Your claims have holes in them....There are plenty of people that see, back to back, to back results in the 500+ rwhp area.

K, all I keep hearing is how the power potential has no ends to it with these things but never see or feel anything but tremendous amounts of heat.
They do work awesome to a point but this person wanted to know if he should go with a 112 or a 122 when he has plans to up the cubes down the road. Sorry a 112 shouldn't be on a decent flowing 6l trying to make 10+psi. They work awesome to a point, just seems to me everyone thinks that they are good for 400+ci engines lol.

To answer the original posters question with some educated information, with your current combination 5.3/4L80-E I would suggest a MP122 with a spot on calibration. Remember the more pressure you pump into a STOCK motor the more of a risk you are taking. I don't care WHAT you are using for FI if you are running the higher boost pressures, your calibration better be dead nuts perfect.

Right on, I just get a little tweaked when people state that the maggie should be put on a wild 454 lsx and it will work great lol.
Its not that I hate these blowers. In the right application I love tuning them. Here is a buggy I did with a stock cam only 5.3l with a 122 and a 3" pulley.

im only wanting to run 9-10 PSI on a stock 5.3 with room to upgrade motor and boost. so what is the difference between 9-10 psi on on a 122 or a 112? and by calibration your talking about tunning right? to make 10Psi on a stock 5.3 with a 112 what pulley would you need? what pulley would you need on a 122?
