C32 Dyno 300 rwhp with just filters
I decided I would dyno the C32 after I ran a 8.5 at 82 mph in the 1/8th on a 90 degree day!
Well, I dynoed my vette the day eariler and got 400/367 with the converter locked. So I wanted to see the C's number. Well guess what it did 300 from 6000 rpm thru 6300. The guy operating the dyno did not hook up the cable to get torque but we figured rpm by using mph vs. gear. Air fuel was 12.1 accross the board.
I can post the graph later but I was pretty impressed. Had to run the car up to 93 mph before hitting it cause it would down shift. Sounded wicked on the dyno cause you could actually hear the blower!
Come March I am going to do pullies and computer program! I am also going to the quater mile track to see how it will run!

Wow Im really excited to dyno my car, but after the mods of things to do
before of course. Was this on a dynojet? If so at conservative #'s, 300rwhp
equals 360bhp! (300rwhp x 1.21 = BHP)
I'm hoping to make 400rwhp and 400rwtq on my 02 C32!

400rwhp out of your C32? You have to run well over 21 pounds of boost to get that out of a supercharged 3.2L. Are you going to change fuel injectors and make sure the fuel pump can deliver enough fuel? What size of pullies you going with?
My vette does 400 at the wheels with just a cam and stage 2 heads. It runs consistant mid 11's at 116-118.
Good luck on getting 400 on your C. I may do pullies and tune to get 330ish and be done modding it!

I hoping to get 400's both rwhp & rwtq by opening the exhaust (full system),
the filters, the pulley, some sort of water/alcohol/methonal injection kit, and
some custom tunning.
On my old IS300 Turbo (with a T04E) I made 425rwhp & 411rwtq @ 17.3psi
with 93 octane. The only mods besides the turbo kit was a headgasket to
lower the compression and a valve body upgrade. Stock motor, stock tranny.
And then on my 95 M3 Turbo (old set up) I ran my car 14.5psi with a T61
turbo made 440rwtq and 460rwtq, this was done on a dynojet too like my
IS300 so I dont think its that hard to crack 400's, then again Im new here
and Im learning whenever I can when Im not at work (which is all the time).
I've got alot of reading to do, but from what I can gather, our C32 stock runs
14.5psi (1 bar) and thats a pretty good start, just open up the exhaust
properly and the psi WILL drop. Change the pulley and tune it properly and
I don't see how what can stop the car to make 400's to the wheels

The only real way to get to 400 rwhp in the C32 is to boost over 21 pounds. Every pound of boost there is a larger drag on the motor from the supercharger so I wish you luck.
I have thought about removing the supercharger and putting a turbo on the C. Nothing large but able to push 17 psi. At 17psi on the C32 you should see at least 400 rwhp.
Let me know if you get there using the supercharger. I would love to changes pullies and tune and get 100 rwhp.

I don't think there is anything to gain in the exhaust, even when the C32 is modified. I did dynos before and after removing just the secondary cats, and removing all 4 (primary+secondary) cats, and there was no gain. The cats are the biggest restriction, so I don't think that moving to larger piping is going to produce any more power either
you will loose boost. I'm gonna ask my mechanic to explain to me again why
it does that was working in a BMW shop doing all the things above for over
5 years
You are forgetting, the C32 is supercharged not turbo. Openning the exhaust on a turbo car allows the turbo to work better, there will be minimal gains on a supercharger.

I've dealt with turbos, superchargers, twin screwed, and clutch driven
superchargers too...
If what your saying its true, then I think the C32 are equipped with a under
sized supercharger, because generally rule of thumb 1psi = 15hp increase if
correctly done.
Its very possible. Just gotta gather the right box of parts and good tuning
and walla... and Im talking about the 100rwhp increase too

on sat i dynoed 320 rwhp this with full sl55 intake.
this was abaseline before my stg 2 mods.
i had placed two 16mm vents before the stock muffler. when running with vents open the car pircked up 12-15 hp /40 ft lbs torque around 2000 rpm but went away as rpms climed. confirming my seat of pants feel.
i am installing a supersprint muffler as part of my stg 2. will not be able to quantify it's effect due to the other mods being done but will be able to post results of c32 vs sl55 intake, as well as improvement on 100 octane. these are changes i can make as car is strapped down.
i definitey think there are gains to be made with the rear muffler. in fact, the sl55 intake plus a free flow muffer may be stage 0.5.....:-)
not sure what dyno...but a stock evo puts out 240 wheel hp according to the shop. pruven performance.

Sorry I have been working. Please send me your email address and I will send the graph. I dont know how to post it here.
My 32 must be strong as I raced a 2002 C32 and pulled 2 1/2 cars on him to 100.

I have done the SL55 box and green filters and it seems to do almost nothing for power. Maybe a slight gain between 2-5 hp but a difference like that can be marked up to almost anything when swapping between 2 runs. Muffler really does not do anything as well and that has been confirmed by vadim, renntech and many other tuners. The C32 exhaust is actually very well done and flows enough stock to work with really modded cars. Any upgrades are all for sound and looks.
The new exhaust setup that I have been working on is almost done....

guys sorry my car is still at speedtechnick. some difficulties with the stg 2 install. i had decided to add clear headlites halfway through and that also buggered up the process.
i apologize i made errors on reading my dyno chart. when i posted the above info i was at work. i'm looking at the graps now infront of me- 30 ft lbs with the "vents" opened up. as to rpm well it think this was a 3rd gear run, no rpm data but max power was 314 at speed about 102mph. there was spike after that kicked the 320hp #. the torque gains are from 40mph to 50 mph - i will calculate the rpm range tomorrow. (102mph = 6200 rpm, therefore 40-50=??) this with 265/30-19 tires
i promise photos of the modded stock exhaust, original dyno chart, charts with stock intake, sl55 intake then effectt of race gas.....but for most of that ...well...hell i need my car. c'mon speedtechnik!

40-50 mph on graph is not going to be 2000 rpm. Jerry. PM me an address i'll copy the graphs and sent to you. i don't have a scanner. at least i don't think i do. i have aprinter here as home that may scan but please don't ask me to figure out how to use!!!

I apologize for hikacking your thread cscollis!
How would one go about testing/checking to see if ECU remapping / custom tuning was done to your car? From reading a lot of your threads about the various tuners out there, it seems that it is pretty hard to tell if your ECU has been further tuned. MB certainly hasn't detected anything on my car as yet.
The reason I ask is that I dynoed my car with just new IK20's and kv85 wires and I am at about 320rwhp. Several other AMG's were dynoed on the same machine, same day, etc. and they pulled exactly what their predicted rwhp should be. From reading other threads (especially Vadim's), I see that the normal variation for C32's rwhp should be between as low as 275 to the high end of ~290. So, since the plugs and wires really shouldn't be doing anything significant hp-wise, there's something up with my car (and I'm not complaining!). I bought it used and would love to know if somebody already modded it!

Take a look at your pulley, and see if it has any numbers or writing on it. I know mine says Renntech. If you can, take a pic of it for us to see.
Sounds like you might have gotten lucky!

Everything looks OE with MB part numbers on them. The pulley looks OE also - no signs of logos or welded rings. It doesn't make sense!
BTW - here's a vid clip of my dyno
