Good point,.......... will do.

Midnight Koop

i doubt the gains are simply additive, so i don't think you'll get 50... but i really hope you get at least 30+

goodluck!

BlackLiquorish8

thats awesome i wish i had those funds.... those mods are lookin good

hawaiian

Don't know how that works really,.............. I'm just going off what I was told by Kleemann. Being that they've installed/dynoed them before I have no reason not to believe them. The dyno results pugguy2001 posted are also on point,...... he said he's got about 246hp (which is +57hp) at the crank w/ same mod. So I'm hoping to get somewhere in that neighborhood,.................. we'll see.

i hate you i'd actually be jealous if those headers didnt cost $1100. talk about price gouging.

tee_tz

Congrats! Enjoy...

How much do those parts cost though? Thinking about it, to me it no longer makes sense to get a supercharger, I might as well upgrade to a C350 (268 HP) or possibly C55 (362 HP), considering the SC will cost thousands and in the end the C350/C32/C55 are already built for the performance, not to mention possibly have more power. My only issue is that I love my manual gearbox and it'd be fun driving a manual supercharged Mercedes, it'd be among the few in the world.

Hmmm... decisions to be made...

I agree it's not the least expensive, but you do realize it's almost half off it's normal price. As far as price gouging, I wouldn't say that; I'd pay $1100 for Kleemann headers anyday. I'm sure others would agree.

hawaiian

$2500 total for parts(sale price).

sim_benz

oh, man!!! dude 1100 for kleeman headers? damn...TOTALLY wouldve done it without hesitation...when people say "parts are no longer available" does that mean that they are no longer made for the older engines, or that they are just out of stock at Kleemann USA?

BTW, i agree that the properties of parts are probably not additive just because a jump from stock up 25 is way different than a jump from +25 to +50.

And dude...SCs are rediculously expensive....just buy a 55!

BIGjohnny

I'd agree, i bought one as well.. but damn you again for putting me on hold for that booster kit! Now i'm left with none. Lol.

I'll have mine headers install this Saturday, i'll let you know how it goes.

Renntech pulley and SI tuning FTW!

You guys are forgetting that those K-headers have been dyno'd independently by Chris (CMoriart) outside of Kleemann - dyno showed +8RWHP near top-end w/ a loss of torque in the low end for the first 2000RPM. This, in effect, is what drove me to develop my headers, which gained 12-13RWHP, with no loss anywhere in the powerband. Both on independent dynojets.

I might make an independent-run of mine again to be advertised with one of our forum sponsors - just like 1FAST is doing with his custom header project. We'll see.

mig888

Let's thoroughly analyze what's been going on here...

A direct quote of CMoriart's post on the "other forum":

Obviously, the boost kit is doing what it should. Total increase in torque in the low-end, increase in power throughout - showed on paper for the highend. The pulleys and FPR push that what little air can go through. BIG difference in driving feel, ask Blake/Drex whoever's driven EVE pre-phoenix era.

KLEEMANN never got around to producing that ECU-Remap due to cost-effectiveness, btw. I say again, the only people to develop an ECU tune for a K-BOX+ tune is (and only) SpeedInnovation - I'm not pushing a product, that's just a fact. Come to think of it... I might be the only person here to have it :\.

Anyway, back on topic. No matter how you think about the above post (WHP or FWHP) - this should now suddenly alert you to which Kleemann upgrade is most bang for the pricetag.

mig888

Raise your hand if you've seen this more than 5 times :\.

Explanation - so this is a RWHP dyno. Let's round it off to an 18% drivetrain loss from crank then maybe things would make sense.

So I dynoed at ~160WHP with the boost kit on - weird huh? Gained additional power after my first prototype header, 172.5whp/186.8wtq.

Translate that anyway you want, but that 250+ at the crank? Maybe if they retailed fairydust at WalMart we'd all have it. I have tested the limits of the M271 to perform as far as it can possibly go... there's only one route left. .

tee_tz

Exactly. Think about what your paying for this part + your car's payments and worth and look at the cost of a used C55 AMG or slightly moded C32 AMG... The price difference isn't so much; yet the resale is extremely better.

I have yet to see someone break the 200 whp mark on the m271. My car is in the process of being completed, but I'm not even sure if it'll get back on the dyno.

In order to gain 50hp, it'll take more than just the headers and boost kit alone. For those of you that are expecting huge gains, I'd greatly lower your expectations. Tuning will help, but then you have to account for the AFR (Air Fuel Ratio), which already runs very high stock! I've got custom injectors to solve that issue.

Good luck with the mods, ladies and gents!

Blake P

Why the hell not? Isn't that half the fun of tuning in the first place?

C230 Sport Coup

Yeh, it's surprising that Kleeman, not some shlock fly by night company would claim 25 hp from a header on a < 200 HP engine?
Thats > 12.5% increase in HP.

Though I notice the torque is greatly increased, but dang those 1.8's don't hit their stride till 3800 rpm?

One of these days I gotta get a dyno.
My car just breathes since I put the header on, and sucks the gas too if I'm not careful. Wish I could find an intake system to replace stock that would increase flow and HP.

And BTW, congrats on the parts!
Thats a chunk of change but it'll be worth it.
Only other thing would be a muffler or exhaust.

hawaiian

Wow!!!!........... alot of action since my last post. I didn't mean to get everyone all up in arms. I'll call Kleemann tomorrow to clarify what they said; I may have misunderstood something. Now I have a question about the dyno #'s that's been thrown around,....... were the cars dynoed in dyno mode? Now Drexx you said you have yet to see an m271 break the 200 barrier, but pugguy2001 says he has.
Another example is what's on Kleemann's site, they claim that a C200 with the same m271 went from 163 to 210(don't know if was at wheels). Of course that's what Kleemann claims so who knows exactly. Truth be told, all of this means nothing until I get the install done and my own dyno results.

hawaiian

Believe me,.... I know I can't come close to either of those AMG's w/ under 50k miles for the price I paid including the Kleemann parts.

hawaiian

Sorry didn't know at the time........ Looking forward to u/d's on your headers/install.

drexappeal

This is at the crank, not at the wheels.

mig888

If I uptranslated my dynos to crank I'd have 207FWHP? .

drexappeal

It's not possible to dyno this car without being in dyno mode. When the car reads that the front wheels aren't moving, it automatically makes the rear wheels stall (because it thinks something is wrong).

So, this car HAS to be in dyno mode in order to dyno it.

drexappeal

I didn't realize he had hit over 200. Wow, that's good. Did pugguy ever post his dyno?
