Im gonna be getting a m90 in a couple of weeks, I am getting it from a buddy at work who runs his thunderbird down at the track, he's gonna be doing a m112 swap on his thunderbird and were gonna put the m90 on my car, obviously its rebuilt, but were gonna make the adapters and everything with scrap aluminum from work, were gonna do some extra measurements with everything and then hopefully get it started. Gonna put a bigger t/b on as well, so hopefully we can get it to work sometime this year, and hopefully wicdked can tune it for me ;P cant make promises right now though.

 

Too big for your engine.

 

no it aint, how is it to big, hes got an m90 on his thunderbird which has a v6, and is swaping out to a m112, i can go up 1 which is to the m90, m90 will be putting me at around 20 psi of boost right off the rip, so as long as I dont go smaller in pulley size I'll be alright, I'll just put a bigger pulley on, and line everything up, if you aint ever tryed to do a swap like that, and your just making suggestions by what you've heard without doing it yourself then you shouldnt be making statements that you have no lagit proof of.

 

butt hurt much i wanna see this done tho, will be a first.

 

yea go for it

 

yeah me to, because it's not gonna cost me hardly anything to do, accept my exhaust which I am gonna do Vibrants header dp combo, and then 3" all the way back, and cooling mods, but I am buyng all of it and then once I have everything I am gonna be putting it all together

 

basically whatever you are trying to do has been studied before, the m90 i not going to yield a gain for you. the m90 draws a lot more power from the engine so you will have to pulley down more. and where are you getting the 20psi from?

 

isnt the m66 the step above the m62? i dunno

 

The m90 is a bigger sc then ours obviously so there I am gonna get more boost no matter what, going down in pulley size is gonna force to much air into the motor on top of more heat, so that will equal bad bigger pulley I will be puttiong my self back to where I am now but I'll be getting more power, on top of a bigger pulley the rotors arnt spining as fast and there's less heat, cooler the engine the more power I am gonna gain

Not sure I havent heard of that 1....

 

I think you need to do a little research before you invest anything into this project.

 

it was on the ss monte carlos

 

"Jarvis sometimes you gotta run before you can walk"

 

seems like a fail waiting to happen

 

lmfao, statement of the year!

 

i understand what your trying to say but when you look at the flow charts, delta temperatures, and the power required to drive the supercharger, the m62 is better fit to our engine. the m62 spinning at 14000rpm @ 10lbs of boost develops 180*F. the m90 spinning at 12000rpm @ 10lbs of boost develops 200*F. the m90 also draws more power even though its spinning at a lower rpm than the m62. bigger blowers are not always better.

 

lol y...? y do you assume that? what proof do you have that all bad is gonna happen....?

 

there is a reason that every person that has tried this swap has failed.....
I'll let you waste your time though

 

humm well has anyone put one on there car yet?

 

there is a reason all of them have failed

 

ok thanks

so who has done it that way I can talk to them on what they have tried

 

I'm not at all trying to be a dick here (unlike you)
It does not work. Many shops have tried it, many people have tried it. It is a waste. Learn how to read compressor maps and charts on parasitic loss and maybe you'll see what we are saying. But if you want to waste your time, it is you time and for you to waste.... I'll just wait to say I told you so in the end.

 

humm seems to me you were, maybe you should try to choose your choice of words, and I am not trying to be a dick, I figured you guys would chime in to maybe help me out and give some pointers, and what I should avoid in the process, not shoot me down like I am doing something wrong, I am just experiementing, and I dont have very much knowledge on sc's but I know people that do, and are wanting to spend some of there free time to help me out. I like your dyno # on ur balt do you do the sc swap to a turbo?

 

car was s/c swap to turbo and thanks.
and I am giving you pointers in my own way I guess. First off it won't clear the stock hood, gonna be right up on the radiator support, Also takes quite a bit more power to turn then the M62 (I forgot the exact number but it's upwards of 15% or so) it's also less efficient than the M62. Airflow isn't that much greater either. Plus depending on which Gen M90 you have, it won't be able to support the impeller RPM to run high boost.

 

I can double check but it's suppost to be a really good one, hes running i believe 8's in the eighth mile with his thunderbird, and with the power I lose trying to turn the m90 wont I gain it back when the sc is running...

 

8's in the 1/8 mile is not hard to accomplish whatsoever. and no, it take more power to turn the higher you go in rpm's
