i have 1200 to spend on my car...any ideas of good mods? performance? i already did my exhuast, it it made a HUGE diff. now i'm looking for a another 30 horses in pwer let me know

ohlord

me count the ways
Gotta go move a bunch of stuff before my Oldest Daughters wedding
I will put together a list later on.$1200 and all you want is 30H.P.?

What exactly did you to your exhaust if you don't mind me asking?

Dr. C36

Crank pulley is the #1 modification you can do, beyond that weight reduction helps a ton. In addition getting K&N airbox filter & silicone intake coupler definitely is a nice plus, smoother acceleration with a bit more top end kick and much nicer intake noise.

Dr. C36

Oh btw, forgot to mention.

I spoke to Oliver at Speed Tunin USA and he said he can do a special stage 2 software for the C36 with a higher redline of 7000rpm and a more aggressive tune for intake, exhaust & etc. You might want to get that, our cars make plenty of power on the top end and could use the extra 200-600rpm (depending which redline C36 you have, some are 6400 some 6800). The car can make power to 7000rpm easily with a few mods. Hope that helps.

yeah i was about to say. the chip is one of the most cost effective upgrades. relatively cheap and noticable gains. i would go with the crank pulley + chip, along with that the Dr. perscribed (high flow filter, be it K&N or Green, and a secure intake coupling to ensure high airflow for the now more agressive motor)

oh btw chip will give you better fuel economy as long as youre not flooring it around, in which case you will have decreased fuel economy.

as for my exhaust i added one magnaflow cat kept the reso, and straight piped the rest. car has an awesome sound, and is a beast on WOT and is a whole diff car on the freeway, top end torque is awesome, car feels free. accelration is great also. got it all done for about300

SeeKlasse

nice! great price too! my mechanic has a guy who works at his shop that is a welding master, he used to build OCC style custom choppers and things of the sort. they quoted me 200 bucks to weld in all new high flow cats (i pay for the cats seperately). even the hard to reach/replace pre-cats will be swapped out for higher flow cats.

Dr. C36

sounds like you are right on track to an excellent setup. I HIGHLY recommend putting in Royal Purple engine & differential oils as well, you can pickup a few more ponies & mpg as well that way.

The crank pulley comes out next week, I will make an announcement then. Any pics of your exhaust system? i'd love to see how you did it. Thanks

put gas in a container and store it in your garage.

Dr. C36

hahaha, you know what funny... thats probably one of the best investments you can do. get a 55gallon oil drum... fill that sucker up. Put in a bottle of "STA-BIL" and gas should last a few monts at least.

Z06EATER

thanks guys yea sure i'll take a few pics, and ohlord i'm waiting to see what you have for me as well.

SeeKlasse

55 gallons wont last long, i go through 30 gallons a week sometimes!

Dr. C36

55 gallons would last me at least 2-3 months, I only drive about 3500-4000 per year. I guess to each his own.

IMHO, $1200 falls squarely in the "cosmetic modifications" price range. If you really want meaningful power mods (like even at the 30 whp range) you will have to pay a whole lot more than that. So maybe the answer is to keep putting pennies in the piggy bank, so to speak??

SeeKlasse

i think if he got it chipped and spruced up the intake, along with a crank pulley, he would get much better power. i recommend upgrading the plugs to ik16 denso iridium power. im pretty sure the c36 uses a coil on plug design so no wire upgrade potential.

all above noted would be less than 1200 and good for at least 25hp. the chip alone can do 20. and if what dr. c36 said is true (getting 21peak hp with crank upgrade) he could potentially improve his hp by 41 if the gains coincided in the same rpm range. since that is unlikely, it is reasonable to say he would make at least 25, which are very nice noticeable gains.

crazeazn

im trying to justify getting a crank pulley along the lines of it will save me gas.

Dr. C36

Yes C36 is coil on plug so you can't do wires. I did Bosche super coppers, car runs very strong and it has plenty of spark so no real need to upgrade that. In fact alot of these older engines do not like platinum or iridium and actually run better on the old bosch super coppers b/c thats what they were originally designed with (same is true of BMW M50/M52 engines, they hated updated plugs).

The gains on the pulley have been proven and dyno tested, However, chips are not nearly as high as their claims suggest to be. Realistically if you get 10 wheel HP from software upgrade you should be very happy. Some W210 E55 guys don't even get that much from chip. However I feel C36 tune maybe conservative so who knows, there may be more power to be had. I think getting to 320hp/tq is not as far fetched as many may think. Crank pulley alone gets you to about 305 ft lbs of torque (18wheeltq gain @ peak, 22.5 crank tq, 21ft lbs is maximum highest gain but not at the peak), leaving only 15 left with $600 remaining. Software is roughly $350 for the stage 2 chip (thats the price oliver gave me for the AMG models). That leaves another $250 for other stuff (in his case since he's done exhaust he could put that $250 to something else). He may already have narrowed that gap with his exhaust, but without dyno gains its impossible to tell. K&N and silicone coupler should pickup about 5 crank HP tops (I doubt any more then that at best).

again, its not nearly as hard as people assume. These C36s were really conservative. afterall they are only making 76HP/L stock which is hardly pushing it, especially for such a well built motor as these 3.6Ls

I think its entirely possible within that budget. The torque hitting 320 is easy, the harder part is getting the HP up to that level. With more free flowing exhaust and the minor intake tweaks and software I think it should be possible.

Just my honest opinion, don't every underestimate AMG

Dr. C36

Yes it will, estimated savings is roughly 3mpg (im being conservative as I can be). The M113 one saves 2mpg but it isn't nearly as aggressive with the weight savings and inertia as this M104 pulley (totally different animal). Once I did the conversion I realized why these M104s were so notoriously inefficient for 6cyls, Its all in the stock crank pulley design (which to be honest is TERRIBLE).

I can assure you any C36 owner who installs it will fall in love with their car all over again, it really is the #1 mod you can do on these engines, nothing else will make this much HP&TQ per $ as this (excluding ghetto NOS of course, but I mean REAL permanent modifications). The other pulleys are nice, but this one is a real GEM and my personal favorite.

FLYNAVY

I'll believe it when I see a dyno chart showing the cumulative effect of these mods. I have a hard time believing that on a naturally aspirated motor, you would see anything greater than a 2-3 hp gain with a pulley upgrade. IMHO manufacturers claims are pretty much all BS anyways until proven otherwise by independant sources, at least when it comes to aftermarket tuners.

SeeKlasse

the Dr. IS an independent source, he designed the pulley and tested it! plus hes got dyno charts somewhere floating around, i think i saw them on club202. Dr., perscribe this man a dynochart for his pessimist ailment.

Dr. C36

Where have you been, The dynos have been out for a WHILE.

Dr. C36

And just to put the icing on the cake, here is the M113 pulley on C55...

only 2-3 HP huh? lol

i keep reading about the ECU adaptation. do u reccomend installing the pulley and then getting the chip repgrogrammed or does it not really matter? im also curious because, for example, when i bought any one of my cars i would have my mechanic reset the ecu and everything else so the car adapts to my driving, would this procedure have any effect if i had the chip reprogrammed?

im pretty sure im going to get my perscription filled for some more horsepower soon Doc so make sure you got the m113 pulleys in stock!

Dr. C36

No it doesn't matter at all. When you get a new performance chip it changes the hard numbers within the ECU itself, Fuel maps, loads, ignition timing & etc. It does not eliminate HOW the ECU adapts within those new ranges. The ECU reset trick (via pedal) just wipes the short & long term adaption and starts over fresh relearning how you drive. After the first 3 days the short term adaption behavior is set and then it switches into long term from there pretty much. Short term adapts very quickly, long term gradually changes. ECU upgrade is not required with pulley, although it of course cannot hurt. B/c the engine spins up faster ECU has to readapt. If you do pedal reset and start out casual driving for a few days then gradually increase the sporty behavior it will adapt usually with in 5-7 days tops.

I have plenty in stock. no worries there, although these things are starting to sell like hotcakes. Thx
