I have a 2008 c300 could I get 300 hp? What all would I need? Tune, Headers, exhust,...

Kleeman can do it on newer models, I bet they could push 300 on yours.

EDIT: actually probably not on the m272

There's a pretty slim chance for 300hp out of the M272. Tuned, it is at something like 245? And I don't know if headers are made for the 3.0L, I think just for the 3.5L in the C350.

Unless you are willing to do something absolutely insane like add Nitrous- you won't reach 300 hp. Even if you could- it would be more cost effective (and safer) to trade your car for a C350.

That's what I thought. Whats the most y'all think I can get?

ilumunus

I could see 260 being feasible within a decent budget/without crazy fixes..

I have a 09 c300. A tune+minor extaust mod+k&n filter will bring you to the same level as the 2013 c300 4matic 3.5l. Me and my friend who has the 2013 did a couple test and our acceleration is about the same.

ilumunus

Oh, nice, I was right. I wasn't 100% sure when I had mine so didn't bother messing with it, I definitely would've though haha if I knew that it worked.

Hows the steering feel on your c63 compared to c300? After borrowing a buddy's e90 335i for a week I find that the steering response on the c300 is life less.

ilumunus

So, I don't know if you had heard this earlier or not, but I picked it up from around 200-250 miles away, and the drive home, oh boy!

It was so different, so much faster, so much more responsive, I was afraid I was going to oversteer and cause a terrible wreck (I survived, me and the car unscathed). I don't know if you've driven an e93 M3, but the 63 is probably about the same/maybe a teeny bit less responsive than the m3.

If you're ever in the 919 area, hit me up I'll let you try it if I can drive your monster (lol jk, you're far away so you probably won't bring it down, but I'll still give you a shot if you want) :P, I love the mods on your car btw.

EDIT: forgot to mention I'm a pretty new driver which is behind most of my uneasiness, but for someone with a few years of experience, making a switch won't be too bad.

EDIT 2: I don't want to hijack this thread, feel free to PM me if you need anything!

Your car looks plain sexy! I've never drove a m3 or 63 before but I'm pretty sure it's unforgettable. The weather where I live doesn't make sense buy any exotic cars because they'll be in the garage for 8 out of 12 month. Im actually visiting NY next year but probably not driving, feel free to drive my kia rental when I'm there XD

Has anyone used obx headers? They are under 400 vs. kleemann 2200.00. Is kleemann 5 times better? Does anyone have any performance specs for both. I think I will go with headers, exhaust, tune, k&n, work on the air box and maybe add a slk Intake Manifold. Any other ideas?

Wish there was some kind of cheap tuner for our cars =)

C300Sport

I got my OE Tune and handheld tuner for $595. I won't say that it transformed my car into a rocketship but it definitely gave it a healthy bump in power and a bit more enjoyable to drive.
If I ever decided to install headers, it can add another nice little bump as well...

jbanger42

can you go more in detail cuz i just bought a 2009 c300 and was wondering what i can do to get just a bit more power out of it.

catmandoob

Trade it in for a C63 is the easy answer. I did OE Tune and almost dabbled with the rest but it's honestly not worth it for the maybe +20 HP you'll get. The M272 is a good reliable engine in that year but the 3.0L version just doesn't have much in it really. Find a C350 if you want a small bump in power or snag a C63 for the best feeling w204 variant.

One reason is the “personality” of the M272.
It is a naturally-aspirated engine without a turbo or a supercharger—> it hasn’t got that much torque and delivers the maximum torque at quite high rpm.
