just because you can do it, doesn't mean you should/or have to in order to reach your goals.

It's still a "V6 blower." It'd be like putting a T3/T4 turbo on a Mustang GT. Yeah you can do it, and it will make more power, but there are better alternatives.

exactly what im trying to say. why not put the most efficient choice on? just because you are happy with 400 hp for now doesnt mean you wont want 500 or 600 later, you go with the bigger blower and get to your goal, then in 6 months when you want more you wont have to go buy another blower to get to your new goal.waste of time and money, and if your on a budget that just means you have to save some more pennies, it will be well worth the wait to not half *** it

Yeah, enough people bitch about putting a P1SC on a car instead of a D1SC... if I had another Mustang GT (which I wouldn't buy again, unless it was a new 5.0) and I wanted to supercharge it it would definitely not get an M90, just in case I wanted to run better than mid 12s at some point.

A turbo works nothing like a roots blower. The M90 is designed to work with any motor between 3.0 and 5.0 displacement. Just because it needs to be spun a litte quicker than an M112 would need to be spun doesn't mean the delta temps are much different. The Generation 5 M90 is highly efficient for what it is, and could support up to about 450whp reasonably. The M112 allows for a slightly higher ceiling, but nothing like what F8LPOS would have you believe. Something around 40rwhp more in an ideal scenario. If you want to get technical, the Generation 5 m90 is slightly more efficient than a non-ported m112 and would be a better choice if you're looking to run low boost (since the blower is smaller it takes less power to drive it). Think about it, you're talking about 22 cubic inches, how much more power can you really make? F8LPOS would have you thinking we're comparing a 3.4 Kenne Belle to an M45 Eaton.

I'm pretty sure NitemareTA's brother has gone 12.3 in his GT with next to nothing other than an M90. He's only running 6psi and has a pretty decently big pulley on the car.

I don't think I'd go roots/twin screw in the first place, would go centrifugal if I did a blower at all. If I go boost, it's turbo for me

This is a pretty easy way out of the discussion.
I can't find it right now, but there was a big write up on the GenV M90 vs the M112 blower. A guy maxed out both of his setups with each blower and found them to be within 30whp of eachother.

My father passed away 5 years ago. There is a reason I'm not indulging these idiots by participating in this conversation.

^much respect. I can't believe this thread is still open anyway. Anything informative ended with the first few pages.

So you're trying to say you're his mom? Wow way to walk into that one.

Feel free to take your shoe off and choke on it at any time.
You're so intelligent. See below

^^^ THIS. The M90 will create a lot of heat at the same boost as the M112 because of the little blower is working harder to compress the same amount of air therefor making it less efficient.

I'm done arguing with you because it's like talking to a retarded junkie teenager.

that would require reading and he didn't complete this task the first time so....... well you get the picture. LOL

better to just give up before we lose our minds.

Hey dude, don't take internet comments so serious. My sincere apologies if it upset you. You could have just went along with it and said your mom told you RacerBill has a little pecker or something to that effect
