ok i am going to do a custon intake for my new motor when i build it to put a roots sc on top of split port heads and i was woundering what the difference between the eaton m 90 and the eaton m 112 is

 

Personally I don't think anybody here knows that answer. Find a website that sells both and send them an email, or call them and ask them. Nobody will know better than the vendors that sell them.

 

didnt the m 90 come stock on the supercoupes??? i dunno bout the m 112 though. sounds like it would be bigger lol.

 

i'd be interested to see what you come up with as far as intake plans

 

the m112 is bigger. i hope you realize how much work is involved in this. you are going to have to custom fab a manifold. roots blower don't have a "built in" manifold like twin screws do. explorerexpress.com uses the m90 for their 4.0 blower and it works pretty damned well. you should talk to them.

 

you need to be single port for an m90 theres someone on here with a red new edge thats doing the swap, i cant think of who it is, try 3.8mustang.com to

 

talk to tomzac on 3.8mustang, he has done a M112 swap on his splitport.....its pretty badass looking

 

i been told on another site that its off an 03/04 cobra
