Do you guys think a fully modded C32 could take the new M3?

BigBodyBenzC240

Define fully modded?

jturkel

yes i do

i bet i can right now. Mike (Hooley) says he pulled on one pre-supercharger and that my car is currently faster than his pre-s/c'd setup.

once my headers are installed and i get retuned,....it will become a definite yes.

Gramma_Benz

I'm trying!! LOL

jturkel

i think mine ALMOST qualifies as "fully modded".....

there isnt much left i can do. just install my headers. no one makes a TB yet or an upgraded I/C that has proved anything. and no one does a cam b/c, well, its not worth like what, 2K? is it 20 CRANK hp for 2K? lol

maybe some kind of liquid CO2 kit or something. meth injection maybe.

BigBodyBenzC240

Theres another go fast mod!!

jturkel

haha ik......i'm not really interested in that anymore. i started a thread a couple yrs ago how i ordered a kit, but then i chickened out and returned it. i know forum members are running it, but it has always been a concern of mine that running nitrous through the blower may eat away at it. i dont think i'll do it.....i'd probably upgrade the blower or go turbo first lol.....

BigBodyBenzC240

A rear mount turbo? A water/meth injection wouldnt hurt the blower I dont think. But yeah I do believe your car would be considered a fully modded C32 and Hooleyboys C55 is just fully modded and then some!!

jturkel

who knows? maybe.....Eurocharged just turbo'd an SRT6, though not rear mounted.

I think water/meth injection would help. It is especially hot where I live and I feel my car losing power quickly in this heat. Only down side is the possibility of running out (which of course, i would get a gauge or something to monitor it) and i would have to tune for it

Hooley's car was super nice before he S/C'ed. NOW, its a beast of its own. Can't wait to see it on the dyno tomorrow with those new headers. mmmmm.

Mike and I have been talking a lot about the M112k a bit (me + bar + mike = us + MB mod discussions. haha. we have some ideas up our sleeves that might squeeze a little more juice out of these.

BUT back to the topic, yes i think a fully modded C32 can take down the E90 M3.....i'm just waiting for the opportunity

FrankW

running with the new M3s. yes. beat one...maybe it's 50/50

stock E90/92/93 M3 only dyno around 346rwhp on dynapack as I've seen on M3post someone posted their dyno. I did 353rwhp on dynapack.

jturkel

i dont really know too much about dynapacks, but from what i have been trying to search about them, they read high-ish like dynojets. what mods are on your car Frank?

VRP put down 363whp and 261wtq on a dynojet on a stock E90 M3........and if i use that calculator (http://www.to4r.com/calcs/pwtq.php), it converts my numbers to 412whp and 422wtq. Do i believe i can do that on a dynojet (aka, is that calculator 100% accurate)? Doubt it. Can't really compare dyno to dyno (which we all know). But from what I remember hearing Hooley tell me, I dyno at least 80 more wtq then M3s and have similar whp numbers (as mike as told me he has seen on the dyno dynamics at dynocomp). With their added weight, i think i would pull a little bit.

and by beating one, i obviously do not mean like, pull CLs and buses. Just like a CL or something through 2 or 3 gears (of course in Mexico or at the drag strip)

we'll have to wait and see!

FrankW

dynapack is most accurate for comparative tuning. the dyno is bolted to the hub, so you don't have a variance in different wheels and tires to worry. maybe couple % difference if you add wheels into the mix.

don't know if they read high or low, but just point of reference.

stock M3's rated 416. 346-348rwhp on dynapack = to about 16-17% loss to the hub. I think it's fairly accurate.

when i dyno mine i had ecu, delete res, intake, exhaust and pulley, but i don't have a baseline on it.

stage 2's more than enough to keep up with stock M3s except they have amazing gearing that even with much less torque they still MOVES.

TemjinX2

that seems kinda low for a dynapak numbers. Dynapaks, read the highest out of all dynos because its power to the hubs not to the wheels. But franks right, its easier for tuning on a dynapak. Usualy dynapaks read about 8-10% higher then a dynojet.

FrankW

here's a graph from the guy on M3post whose always dynoed on dynapack from stock to RD stroker motor.

he avg out the runs. tossed out the either highest or the lowest

AMS Performance

An AMS Stage 3+ CLK55 AMG is faster than an 09 DSG M3. So a fully modded C32 AMG should be able to do it no problem.

When comparing to an E90 M3, its not HP that is counts, its the torque curves. That's the E90s Achilles heel.

jturkel

those things have NO tq...so sad.

splinter

Don’t wait ‘til the twisties.

advans

the Bimmers dont have much tq compared to the equiv. MBs but when it comes to twisties and turns, we have to step aside.


and if somehow it starts snowing, that's where the RS4 comes in.

Jons95c36amg

Too bad the V8 they put in the new M3 is only a 4.0L I did surprise the new M3 though! You would destroy the new M3 from a roll. Your trq will eat it alive!

AMS Performance

They should have just used the E39 M5 S62 motor which would have bee much better for that application. Bevause they have such low torque and weigh 3600+ lbs, they honestly don't feel that fast (much like an S2000). The car is moving quick, you just don't feel it. The AMGs are polar opposite, much more torque & lighter chassis in the smaller 55 amgs (SLK55, CLK55, C55, etc). The only reason the M3 gets the times it does is due to the DSG transmission & its more aggressive gearing.

FrankW

the E90/92 M3 is still lighter than the C32/55 if not the same weight. There's no way a "stock" C32/55 can keep up with the new M3. The purpose of the M3 is to make a streetable track car, so the high revving engine serves that purpose. when in the hills when you keep the revs up in the 4k to redline the M3 is beautifully balanced and fun to drive. On the street it IS pretty boring tho except it looks good. lol

the S62 was a good engine, BUT it is a heavier engine. There's no reaosn to add weight to the already heavier e92 to continue using that engine. The s62 also had a lower redline.

The one thing AMG failed in the new cars is the WEIGHT of the motor even tho the 6.2 revs north of 7k rpm the engine is just too heavy. just when you thought AMG got the formula down with the C55 being able to achieve the same time as the E46 M3 on The Ring they went back to stone age with the C63.

jturkel

a stock one would NOT have a chance, but i think the M3 is still a little heavier. I came up with these numbers:

M3 Coupe: 3,704 lb
M3 Sedan: 3,726 lb

C32 Sedan: 3,540 lb
C55 Sedan: 3,605 lb

a stock one definitely won't cut it against the M3's 414hp. But modded, they definitely have chances.

loungn14

I guess I would be fully modded....

and yes, it wasn't pretty

AMS Performance

Correct, M3 is a porker, even with its carbon fiber roof. 295 ft lbs of torque pushing that much weight... not pretty. Sad for BMW now that AMG is the lighter option between the two (with more torque might I add).

It doesn't take that much to beat new M3 or even the heavier 55Kompressors (stock of course like S55K & etc). AMS stage 3+ setup (headers, pulley, software, & cats) will get you there in no time. For C32 wouldn't take much more than overboost pulley, software, & headers most likely.

Weight reduction is always the best modification but its hard to take out much more than 250lbs on the car without making drastic changes.

jturkel

yup....not really too many weight reduction mods for this car that i know of.....carbon fiber hood, maybe save you 20lbs? light weight battery, saving another 30 or so lbs. that seems to be about it lol. i dont know too many members that have done weight reduction on their car......and it can be quite $$$$ too
