supercharge m104
Headers and new exhaust system will be next to get rid of the absurd back pressure!!

Congrats again, whipplem104. There is a lot more in there, especially when you get your 60' down.
Not bad for what a 3.2L
Saijin, IIWY, I'd forget messing with a 3.6L and just have Whipple duplicate his blown M104 setup on your coupe! Nearly 500hp (at the crank) with a plain 3.2L... awfully hard to beat that. Makes you wonder what an M119 would do with 12psi, eh? Mmmm, 750hp 500E....

A supercharger setup is something I've been looking at, I've been in some contact with the folks at Vortech. However, I'm liking the sound of the Eaton TSV 2300 (Cobra Super Snake uses one). But its likely overkill :P
Did you need to do any internals rebuilding Whipple?
Great question. My guess is, the long block is mostly stock. The Finns push the diesels to triple the stock power levels with stock internals, so double on a stock M104 wouldn't surprise me. Whipple?
I know that 280-350hp at the crank is no problem for a standard m104. The cise 3.0ll is where I started and I just ran it out of fuel. I put around 50k on that motor with boost. If you are going this route then I would definitely run a centrifugal blower with the cise. The positive displacement setup never worked very well with the intake. Reinforce the boot under the fuel distributor with fiberglass and some fuel tweeks and if everything else is in good order 300ckhp is very doable. 6lbs of boost.
The 2.3l blower is good if you are planning on making 500-800hp though.
I would be happy to discuss the ins and out of the options. PM me.
I would luv to come for a ride but I'm like half way 'round the world hehe......
I have a 1989, w124, m103 and i'm really keen to supercharge or turbo charge it.
Recently i've been learning a lot but i'm still very green.
I've got really confused in some parts and because of mixed opinions and unreliability of some advice i'd really appreciate some advice.
I'm looking at either getting a centrifugal supercharger which my father suggests over a turbo because you don't have to have a high RPM to get required boost (so far only looking at about 6psi), is this true with a centrifugal type as I've been told by some that this only applies to roots type and such.
if a turbo and centrifugal supercharger are going to act the same way is it easier to just to go with a turbo as one of you stated earlier? as for now it would be much easier to keep my cis-e system until i have more money to spend on a standalone system.
note also i'm not after a huge amount of horsepower so budget and upgrade-ability are my primary concerns.
Cheers for the help
Also, as much as I love the sound of a turbo blow-off valve, this sold me on the SC setup:

Ok so you disagree with whipplem?
>.< so who is right?
or are you saying much less work as in it is or it isn't

5speede, you do not need high revs to gain respectable boost with a turbo at all. It's not necessarily about revs/boost with a turbo in the first place unless you are planning to drag race it. You can have huge power at low boost & mid revs for instance, if yo choose the right set up!
Generally, SC are harder on engine internals than a turbo. They both need to be set up the right way. Many, many variables to gain what you want out of the build.
Whipple has chosen the SC route in this case & it will be a blast to see it completed. It already is friggin impressive!
3 things to consider way up front of any boosted build. Economy, power & $$$$. Look at all these variables before you jump right in.
P.S. The main thing that interests me with this project thread is that the OP is doing it the right way & folk can certainly learn from him



any updates though?
