Which one should be used on the V6 12V 2.8L
just for future which would be more efective

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

Nobody has any idea what da hell i'm talking about.

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.

Cool keep us uptodate

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.

sounds awesome, have fun
