1320 is 80 cubes.
Not that small compared to the 90 we presently have.

Doubling posting for a reason....
Does anyone know if the Eaton charts are volumetric efficiency or adiabatic?
10-15-2011
i was sent here to tell you that the charts are thermal, volumetric numbers on the tvs would be 97-100% and about 88% on the gen5Originally Posted by matt5112

Quickly realized that VE goes up as the blower spins.
Opposite of the charts provided.
Thanks though.

Wow. No offense man but you are a salesman's dream. I don't get how you can determine the dude is a genuis by talking to him. lol If so I have some swap land in Florida I would like to talk to you about.
He isn't the first person to think of this swap. He is just the first person to try it because it's a lot of money to put into something that nobody has tried and could fail. Actually when he first started thinking about this swap I was also thinking about doing a swap but placing the rotors into a M90 case. After some e-mails I found that it wouldn't work and figured it wasn't worth it.
Show me hard evidence this is going to work instead of speculation and theory. The proof is in the numbers.

why don't u go over to club gp and ask him directly instead of shrugging off his ideas on a forum he can't defend himself on. i can't give you the answer you're looking for all i can do is try to relay the information that i understand.
in short it seems the blower bolts down and works just like the m90, just better than the m90. how much better remains to be seen but i don't think someone with a solid grasp on how things work and how to read a compressor map would be taking such a gamble on power unless they were sure of it. which is what i said, he's very smart and i have a lot of respect for him so if he says 350, it'll be 350 or more.

Guy, no one can register for CGP anymore.
Heres a fun one:
My car is pretty stock:
This is all assuming the same VE, which I know is wrong.
Based on that, the 1900 isn't too large.
However the 1320 is perfect for a stockish car.
Any serious modifications and you should be looking at the 1900.

someone on club gp posted this link
A snap shot of Eaton’s superchargers | Supercharger Performance and Engine Performance Parts
with headroom 150hp higher than the m90 why would u need the added drag of a 1900? the line u drew on the 1900 would have it running like a 5 inch pulley lol
also this is worth taking a look at
10-16-2011
3.4 on the M90.
3.2 on the 1320.
3.9 on the 1900.
Rated HP means nothing when you have the performance map which clearly states that if you were to push the blower any further than what I showed, you'd fall outside of the magical 70% AE.
Yet a 1900 would still be >70% for some time to come.
Based on the inefficient gen IV M90 and M112:
http://www.magnusonproducts.com/images/mp90g2.jpg
http://www.magnusonproducts.com/images/mp112g2.jpg
at 12 000 RPM and 10 PSI, 42 HP for the MP90 and 52 for the MP112.
You spin the M90 to 12 810 RPM, costs you 45 HP.
You spin the M112 to 10 500 RPM, costs you 43 HP.
Fun times.
Edit: Hell lets use your chart.
R1320 14 300 RPM for 1080 m^3/hr at a 1.8 PR.
R1900 10 500 RPM for 1080 m^3/hr at a 1.8 PR.
1320 uses 30 HP.
So does the 1900....
Hmm...

I'm sure nick could tell you why 1320 over 1900 but i don't know enough about the differences to say otherwise
10-16-2011
Cost has been the main point I've seen.
10-16-2011
i was talking with nick about the 1900 and he said a few things to me about why the 1320 is better for our engines.
the biggest pulley he can find for the 1900 is a 3.3 inch. boost levels on his cammed l32 would be outragous, you need a built motor with mods like aluminum heads/ported heads and a 4.2 stroker just to eat up all the air. you r lookin at 900 cfm of air by redline.
by contrast the 1320 will support 500whp or more with the proper cooling and engine mods. its cheaper and easier to make work and even spinning it insanely fast the AE is still better than the m90s AE when the m90 is running at its peak efficiency.
basically if u just want a blower thats better than the m90 and u wanna make non-race car power the 1320 is the best choice available. if your goals are 550+whp on a roots setup maybe u should look into fitting a 1900.
also he said boost levels on the 1320 will be lower than the m90 when comparing cfm vs cfm because the colder air coming out will not create as much pressure. this helps with drag and heat even more
10-16-2011
In short, no it doesn't.
10-16-2011
Magnuson apparently makes pulleys for the 1900 ranging from 2.8 to 4.1.
10-16-2011
can you elaborate on this? im confused because they r both roots style blowers.
10-16-2011
It doesn't "Bolt down" just like the M90 or even work like the M90 because the rotor design and case is much different. If you wanna say they work the same because they are both made my Eaton and they are superchargers then yes they are the same. lol
10-16-2011
Dollar for dollar good luck making a SC car faster than a turbo car so whats the point here? We've been down this road before........
10-16-2011
You'd rather drive a 700 WHP 4g63 over a 700 WHP BBC?
10-16-2011
Yes yes I would, becasue the 1st option likely wont handle like ass and its AWD and I get this weird white stuff from the sky where I live Im sure you do too.
10-16-2011
Because you DD your race car right?
Yet the VE is higher on a TVS than a M90 thus more CFM output for the same input.
