m90 or mp112

right now i have a m90 and have mp112 on my floor all the things to go with it like ported intake manifold and ls1 throttle body with 85mm maff and heads on the way but iv heard that the m90 is better so i would like your guys opinion

99 I have heard that the Mp112 is the one that the F-150 Harley packs. I have seen sites (Not sure if ZZP or intense) where they sell you these for your car or ported M90 that behave like the Mp112. The main diff between the Mp112 and M90 is the amount of air that each of them push on each turn. I beleive the M90 pushes 90 cubic inches on each turn, not sure about the Mp112 but I bet is more.
SO this means that both reving at the same rpms the Mp112 would force more air volume than M90 thru the intake manifold. If you install the Mp112 you must make sure that the engine would handle correctly the added air flow.

i am going all through the motor the heads were sent out wed and i am going to have them all sone up have the adapter plate 99% made and ported and polished ls1 throttle hopefully get the car back this week damn body shop but when i get it back i have a 3" high flow cat and a hooker aero chamber for the exhaust and then i am going to take the tb screen out and hook the ls1m up to it and figure some stuff out. i was told to get the stattama ss4 cam and i would be perfect for my car, i emailed intense on there custom pcm for my setup stage 3 but have failed to give me a response there info on that pcm is kinda vague so i asked them and its been a good week so just waiting

Sounds like your car is going to be a beast.

I just cant believe that you have purchased all the parts and still think that there is a chance the m90 is better.

You havent mentioned an Intercooler? Are you going to try and run the 112 w/out one?

I would also give DHP a call for your pcm. Dont let the cheap price of INTENSE sucker ya.

Im sure down the road you'll want to tune the car more and more so w/ DHP you have the option of getting the ICCU. I dont see anything offered like that from INTENSE.

no im not going to run the intercooler its the same bolt pattern but just cant justify a 1000.00 dollars for a core thats f***in insane and rediculous but i am kinda haven doubts on the mp112 great supercharger but the m90 is able to bolt up and with no problems i havent had my car for 3 months so i am very excited to get it back had to reorder tires again tried to put 235/50/18 and am going to go with 245/40/18 so yea i cant wait i think i am going to sell one of the superchargers i also have a spare ls1 throttle body so i am kinda undecided have you heard anything about the iccu

If your not going to do the Mp112 right then dont do it at all.

Doing it right means running a intercooler and iccu. Sounds like you're unsure about how far you want to take the car? The MP112 is going to give you hte best gains. Usually addinga iccu/dhp package means that you are running a intercooler.

i would like to run an intercooler but i have allready spent so much and need to spend so much more on the heads that i cant really afford a 1000.00 intercooler, there are a lot of people doing the m90 and having no problem keeping up with the mp112 so i am starting to lean towards that and if i decide that i can sell the superchager and get a intercooler for the m90 so ?........

What version of the M90 are u talking about? The new gen 5 off the 04 GTP's ?

or just a ported and polished m90 from a 97-03?

Well if you already have the MP112 then wait a little longer(to make the money) and get the PCM and related hardware to drive this SC. Because you have invested a heck more on what you have already and have waited 3 months to get your car back. What the heck wait a little longer and get what you need(money) to install the MP112. You will thank yourself later to wait a little longer now

jajajajajajajajajajajajajajajajajajajajajajajajaja jajaj Iam the car death wish faerie

i was going to do the 97-03 m90 but kilroypr is right i have invested a lot of money and all i need the run the stuff i got is the zzp race pcm and iccu and intercooler along with my heads but after that theres not going to be a lot that can touch me after this
