VERY IMPRESSIVE STUFF!

whipplem104

Got everything done. Have been getting the tuning back in spec. I gained over 1.5lbs of boost and the intercooler is working much better. It is pulling really hard at only 10 degrees of timing. As soon as I get the fuel in spec I will add some timing back.
Headers and new exhaust system will be next to get rid of the absurd back pressure!!

Wow, I hope I see you on the road or at a meet sometime! Very cool!

whipplem104

Here is the final install. I have to redo some wiring still and clean up a couple more things but not much should change.

DW124

Well done there any updates though?

whipplem104

Finally got some things worked out in the rear suspension and some decent tires and went to the track tonight. Ran a 12.8 at 110 with a 2.1 60'. Cut a better first half my first run but let out of it and ran a 13.6 at 69mph. I was .2 faster at the 1/8 mile on that run. First run though and wanted to make sure everything was going smoothly. Next time hopefully a little faster.

Holy **** dude. Sounds amazing
What kind of HP/TQ numbers you putting down?

whipplem104

Thanks, I have not had it on the dyno for a while but from my last numbers to what I am doing now and the 1/4 mile calculators I should be around 350 whp and a little higher torque. I am going to baseline it soon though before I start on exhaust.

It was awesome seeing this sleeper make a 12-second pass in person.

Congrats again, whipplem104. There is a lot more in there, especially when you get your 60' down.

I saw this in the W202 forum, I would say thats probably close for estimate. In my SC'd C43 I ran similar 1/4's at 112mph and worse 60's around 2.4ish resulting in 13.1 ET as my best. I dyno'd my car to death and got 342whp/370wtq as my highest numbers. I would expect with your trap speeds you would be making around the same.

Not bad for what a 3.2L

whipplem104

Well finally got to the dyno and dialed in. 398.7whp and 383 whtq. Again the cam advance on made more power up untill around 5,000 rpm. New exhaust is working well as I am making power all the way up through the rpm. This is on e85 at around 15 degrees of timing. More timing made no more hp. Boost is still between 11.5-12.5 psi. No ice in the intercooler, so basically this is street hp. It is around 62-65 degrees today with high humidity.

Saijin_Naib

Bad-*** sir

AMGDave

Whipple, that is an incredible power curve. Wow.

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....

Saijin_Naib

My target is around 350-400HP range (at the max), at the minimum, I want around 280HP (C36).

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?

AMGDave

Sounds reasonable. Whipple's setup has already proved it works great, you could probably settle for a little less boost/power and have the engine last a loooong time.



Anything aftermarket would require a ton of custom fabrication. I bet Whipple could duplicate his setup and send you a bolt-on kit (not that it would be cheap, lol).



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?

whipplem104

Thank you guys. It has been a lot of work. I am running a stock motor. I have minor porting at the intake for the larger runners. Other than that a junkyard engine. I have been beating on this one for a while now. Probably around 4-5 yrs. I have probably been over 400 at the crank for most of it. I was n/a for about 6 months at 1st. Other than the last couple of years it has been a daily driver. I probably have 10,000 miles since the last I got this setup running. A lot of tuning time on the road. So a lot of abuse. I have even hit heavy knock a couple of times on a hot day.
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.

As I've stated on that 'other' Performance site. Excellent work man. These engines can handle anything so long as there set up right I would luv to come for a ride but I'm like half way 'round the world hehe......

Hey guys

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

Saijin_Naib

Turbo = oil lines. I'd venture SC is much less work, and for this reason, I'm also picking Whipple's brain about his setup.

Also, as much as I love the sound of a turbo blow-off valve, this sold me on the SC setup:

Nice vid.

Ok so you disagree with whipplem?
>.< so who is right?

Saijin_Naib

Disagree? Hell no. Where did I say that? I said I agree with him completely and that is why I'm picking his brain about his setup, so I can better know what to expect when I eventually tackle this project.

5speede

I thought he said a turbo would be easier to install and when he did a supercharger setup he had to have 2 fuel actuators and stuff, or was that someone else?

or are you saying much less work as in it is or it isn't

BAD300

Not the best place to debate the SC/Turbo pros/cons on someones Project Thread really. However, there is no right or wrong or better boost method, PERIOD. Each method attacks gaining HP at a different angle, achieving similar results.

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

5speede

Yes your right sorry i don't mean to hijack the thread.

Nicely done!!
