Which one should be used on the V6 12V 2.8L
just for future which would be more efective
http://www.automotive.eaton.com/product/engine_controls/superchargers/index.asp
M45 power consumption

M62 Power consumption


some my calculations:
then per 2 revolution of engine the amount of air is 2.8L then the
1 bar = 14.5037738 psi
to make a 7 psi boost it would require about 0.5bar then the SC will require to produce 4.2L per 2 rev of the engine.
so for M45 4.2/0.75 is 1:2.8
so for M62 4.2/1.00 is 1:2.1
so if engine is spinning at 6500 then SC m45 has to spin at 18200RPM for M62 it has to spin at 13650 RPM
so M62 will consume 22HP and M45 will consume >20HP
but if to use even biger one then
like M90 4.2/1.5 is 1:1.4 equal to 9100RPM of SC meaning 22HP consumption.

But if I get M90 then I have a lot of boost level left for improvment. up to about 20PSI of boost can be build on it.

My question is should I even bother of integrating one into the car and trying to use one.
and another question is which one to chose. I mean with M45 there be like 4 psi, M62 is 7 boost, and M90 is about 20psi.

I know I spoke a lot, but I ask for your humble opinion

I do,

and your not going to like my answer.

there are quite a few 12v s/c's out there.

the current one is a m45 and it does not make the boost nessisary to probide psi to the engine.

your' going to have to look at the m62

another place to look is

tnx for the website. and as by my calculations on M62 people get 8psi tops. [as I read]. I calculated about 7psi but if you take into the acount heat desepation and intake restriction gets to like 8-9psi.
I got some desines in mind to get a intercooler in. and I hope to get M90 couse well I will be able to get more boost. But what M62 performence gets might be enough for a simple guy/teen like me.
+60HP from M62
More opinions would be nice.

well on sc audi there is a 12v using an m45 and he's not getting the results he thought. Head over an pm 4 rings he will help you with the calculations.

The g3 by pes for the 3.0 30v an m62 is 10 psi at max rpm. more than that they say you need to rebuild the bottom end of the 3.0.

Sadly for 2.8 12v's there is not a whole bunch of options. Custom s/c is about it. at the very least you need a m62. I think m90 is and might be overkill for the engine. my guess is you'll hit that spot where it takes more horsepower to create horsepower and the 12v does not have it to begin with.

like i said head over to s/c audi pm 4 rings. and ask for links of s/c 12v's

tnx. I was thinking of doing coustom SC. on power thing. how much M62 takes to create X psi it will take M90 same amout of power to create X psi. it is an overkill. if use M90 it will work on like 60% of its actual potential. but it will crate less heat. M62 like 120 delta. M90 like 100 delta. and M90 will live longer.
any more opinions?

Well I have desided M62 with 100% in use or M90 with 60-70% in use.
the problem is that if I go with M90 I will have to make a coustem pully for it. and for M62 I will be able to use regular pully for it.

New Update, I wana make a sleeper, a heavy sleeper. for that I have to find a upgrate for my tranny, which is weak, probably will go with something like Level 10 (L10.com). then I will have to find/make Variator and buy M90 SC. then create coustem mounts and buy SMT 7. using SMT7 piggy back ECU then connect SMT7 to the Variator, I believe its called CVS or something (I will find/build it). Then using Variator I will be able to control Boost by changing Ratio of cranck pully to the SC pully with a push of the buton. SMT7 will also provide extra fuel and a bit diferent matrix. With this setup, all you will see is an extra pully at the bottom, an intercooler, and thats it. also this setup will give me boost control from 0psi to 25psi.
Its all in my mind. I will write, develop, and sell.
By the way any one with V6 wana be mine giny pig? all it will cost you is a parts, and food for me.
it will develop not now but over summer.
keep me posted.

I also wana program the variator to act as boost increase. so like on the turbo. at the begining of the RPM little boost then increase as RPM increase.
that means when like taking it slow the SC will not take too much power for it self, then as you incerase RPM more boost build but more power taking.
smart, ahh.
so at low RPM you have low output then increases and also it would be safer.
I'm thinking of puting at low RPM like 1-5 psi and at hight 7-12psi. so the curve of power is a very steep one. pushing to like 300 -350 HP at full throtle and close to stock at idle.
also switchible mods from eco, which would be a bit eco that stock making about 120-150HP then normal 160-190HP then race 200-250HP then Pro-race 260-300 then @ss woping 310-350HP
And
whoever will forge internals and lower compresion ratio will have DITSDA (Dead in the seat during acceleration) 360-450HP and whoever craeasy enough will have Full which is 460-480HP and "Aub Kraft" will have 460-500HP pushing SC to produce about 30PSI. and not forget intercooler which will add extra ponies.

I'll be your 12v guinea pig, if you fly out to Oregon, or let me crash on your couch while you work on it...

Let me know when you have it planned out, I'm intrigued by a 12v SC option... I was previously thinking about swapping a 30v ans going SC on that, but if this works out like you say... ---->

First, I will have to choose a variator type and desighn. I have three choises, constant as direct no boost control, then step variator goes by like diferent levels of power output, or constant variator wich will give me constant boost control.
its all in my mind.
if you want something like my design but cheap, with M62 blower I will be glad to desighn and make.
the diference is that M62 tops at 8psi after that you have to overdrive it which is bad. and if use intercooler it will drop to like 6 or 7 psi.

Nate074 what car do you have?

hey would you be interested in making an M90 for a 30v 3.0 ?? Or are you staying with the 12v 2.8? I am looking for a less expensive alternative to the 5300 pes s/c with more potiential.

ye sure, it will fit any V6 engine, not turbo. You wont even see it.
I'm guesing on diferent types of kits. they seperate into groups of boost levels.
1. already set boost level on like 5 psi 7 psi 10psi 15 psi 20 psi 25 psi 30psi and maybe 35 psi
2. variable boost level 3-10psi 5-13 psi 10-15psi 15-20psi etc...

I think I will make default kit 1. at 7 psi.
additionals
Variator
optionals:
Intercooler
full set of pulles

The numbers are exaples.

But defenatly if its finished it wont cost 5300 buks. thats just silly. its easier to sell your car, add that money and buy S# car or even RS#

As I predict The cost should start at like 1500 buks or even less. and top at like 3500 buks with all options. I dont know If I will include piggy back, couse I'm not going to chip. but defenatly will work on the matrix for piggy back, maybe injectors too.

My SC is monted on the engine block not engine head.

I gues when I finish school, which is in a month, I will start actually puting it together.

got any pics of the project yet? got any leads for a company making forged pistons, and/or rods for an a4 v6?? possibly a crank, maybe just cryo treaded crank would be fine. Ps i only know of a 2-wheel dyno up here in alaska but would love to find an awd dyno if it weren't to far into canada. anyone know of any?

Nope not yet, I will start during summer.
I hope I will find leads on forged pistons and valves, and maybe a spacer to decrease the compresion ratio.

First finish school, get acepted into college.
Second work on the blower project and my guitar project.

quiqk question. would you like to serpanten belt to fell or variator?
facts:
it is easy to replace a serpanten belt. but more expensive.
and variator if fails then its a bit harder to replace. but cheaper.
===================================================================
second question:
would you like controling boost on fly [while reving]
or you would like to like switch at idle?
===================================================================
third question:
what boost levels whould you like?
and levels to switch between?
note: dont make it too big of a diference.
===================================================================
fourth question:
would you like running bifueled or dual fuel system or monofuel?
note: bifueled system, running on both fuels, like propane and gasoline. dual runing one or another. monofueled only first or second fuel.
===================================================================


progress:
thout of two types of variators. one that can damage serpanten belt ar switching between. and second that damages it self when switched.
I will develop two types of kits. one that uses M90 , and second that uses M62. both will come with IC as an option. Cryon system utilization optional, also anti drowning system w/side afect. also variator optional only for M90. set of pullies optional.
I think M90 will start at like 1500-2000 and M62 will start at like 1000-1600 buks.

new update, I beleve if I use no variator, a bypass valve can be used as a boost control.

the problem is some power will be lost in the proces.

And back to the variator,
I calulate and design a variator with right now 3 speeds.
when runing on stock pulley that will be provided, you will be able to switch between 2-3 psi which is kind of switch.
second speed will be running on 93 octane and about 6-9 psi.
third speed will be running on race fuel or propane/CNG and about 10-15psi.

and you will be have a extra pulley just that you could run also 3 speeds of 6-9psi, 10-15psi and 15-20psi.
and for crazy bastarts you will have another pully running same 3 speeds of 10-15psi, 15-20psi, and 22-30psi

also for people who will just want a constant boost without wories about variator or longlife you will have no variator. and direct drive.

also for cheap kit you will have a M62 blower w/ direct drive making same or similar numbers as PES G2 or G3 :-(

note the numbers are samples, acual values will vary with your engine desplacement, and of absents/presents of IC and of style of intake manifold. :-)

I got a q. where is this s/c gonna sit, cause you said you want to keep your kit hidden. That would be ok with me but would it not be easier to set her on top like the pes is isn't that were a roots type belongs? I know that on my dads 350z vortech (centrifical type) kit he has a serpanten belt the spin with the oem system but on the other end of that gear is a cog type gear of which drives his super charger which would be fine by me. Would that be considered variator. I think so.

http://files.automotiveforums.com/gallery/showphoto.php?photo=26452&size=big&password=&sort=1&cat=3211 350z system

2.On the go boost would be nice, but dot have to have, ps i would like to boost gradually to max not wam bam good bye quattro.

3. Well i dont have forged internals whats a good level to start with?5-7psi?

4. Probably runing mono btw here in ak 90 oct is premium so i gotta watch the mix.

What all would your kit include, say i want to start with making the power a pes kit does but room to upgrade with an m90. If i can find a place the make forged rod and pistons maybe bump up the psi to 12-15

Okey, I will summrise.
Okey, the PES kit dsadvantages: 1. No possible way to put IC in there without screwing your budget. 2. The M62 Maxes out at 8 Psi and then have to be overdriven which shortens its life. 2. its on top and heat goes to top, heating up he SC and decreasing eficiency. 3. Cost
Advntges: Its easy to change and check oil.

Then mine: disadvntages: 1. It would be hard to show off the car locking like stock. 2. I have no tuning possibilites, so I will try to provide basic Matrix for fuel and Ignton to my best ablity. (I might make a promotion, If person tunes his car he could sell the values back to me for a price). 3. I can only start actuall planing this summer or when becomes warm enough. 4. hard to check oil. 5. I will only provide with posible 3 speed variator [off, on, race fuel]

Advantages: 1. can use IC making more boost, and increasing efficiency, I guess extra 10-30HP. 2. Try to designe an alternative fuell system for the kit so that you could run propane or methane, they are like race fuel but beter 110 to 140 octane, clener and healthier. 3. The variators drive would be the weakest point and it would require changing, so the repair kit would cost like 10-30 buks, easily done. about 0.5-1.5 hours of work. 4. Varitor goes all you lose is boost no damage to the SC or Engine. 5. If the SC oil is same as Engine oil then it would be maintainance free. 6. the kit will provide same reliability as PES.

Note: the variator wont be like 1 second you want power next you dont but it would be like wana race, click click and you taking off. or your gramma in town, and you love your gramma, click click and you are ver near stock power. or you hate your gramm click clck and you are a speed demon.
For the stedy increase of boost I chose to use DV.
Its coming up soon so wait and dont kill your self.

PS I will write some more later.

oh ye, why I went with the root type instead the others like centrifugal.
1. The efficiency, the root type is more efficient.
2. its the shape I like and need.
3. ah forget the others.
=======================================================
well right now I'm it the middle of putting together the kit in my mind.
I had idaes, many of them, and well I desided like that.
you will have 3 to max of maybe 6 speeds. each speed will have a dimier so like you switch between them. and each speed will corespond with its boost level. You wont have like increase by 1 psi but more likly by 3-6 psi. so lets say on 2.8 engine you will have 3,7,13psi levels.
On the matter of tuning the Stand alone or more likly piggy back will have controle over it. I will offcouse provide with the basic one, then as I staited before like person actually tunes it, I will pay to get his map, legally ofcouse.
I havent figured out how to make the boost go up and down smothly, but I will get it eventually. I think I will be able to use Piggy to overide some manual controles, so it would be hasle less.
======================================================
The instalation could be pain in the ass, like 6 hours to install, I will make it as Plug and Play as posible. :-)
