Here's the chart I got of the Upsolute mod.

is there a way that you can display the dyno run on just one gear, instead of 4. Its alot easier to see the hp increase over the rpm band from one gear instead of 4. If you cant ta\hats no big deal. Thanks man. That power increase was what about 30rwhp. I'm sold! Imagine that with Renntech pully (which adds 30hp) what a quick little car!

hey wait a minute, the max hp difference from stock and chipped is only about 17 or 18 hp. yeah at that one point its around 30 hp but for most of the powerband its only around 10hp or so.

I think I'm missing something. This is new to me so please excuse my ignorance. :p I thought that the stock C230 had 192 HP. Isn't this only showing 184.2 max?

TimmyC230boy

Revstriker, There is a difference between flywheel hp and rear wheel hp. Car makers frequently quote flywheel hp as opposed to rear wheel hp to make the car look stronger than it really is. You will loose anywhere from 10-20% hp between the engine and the wheels, most of which is lost through the transmission.

192 hp is crankshaft horsepower. The dyno result is rear wheel hp. The difference is frictional losses in the drivetrain, losses due to accessories, differences in the dynos and conditions at the times of the syno runs.

revstriker

Thanks Timmy, Lynn, and Vadim. Now I understand the difference.

So is the blue line before the mod, and the red line after?

vadim

Yes, exactly

for 300 bucks its not at all a bad deal. especially if its easily reversible, and invisible.

i was wondering something, what kinda results would one expect with a new pully, and then a chip? i dont really expect the 50-60 hp gain someone stated earlier... hmmmm

someone fill me in.... i have never toyed with a SC engine before

You can ask Vadim to send you a smoothed out dyno chart in order to eliminate shifting points. All unsmoothed dyno charts appear jagged at the shifting points, and are hard to read because of that. Taking away the shifting points, which I don't think count, I don't see the 30HP that someone mentioned earlier.

Revstriker:
The dyno we have at Evosport, and most other shops, shows the power given to the rear wheels. There is a powerloss due to the transmission (more with automatic), and thus the result is usually 10-17% less than factory claimed HP.

Greg230:
The Kleemann power upgrade kit for the C230 Coupe raises HP by 38 to 230, and Torque by 39 to 239lbs-ft torque. For the price, it is definitely worth it. Give me an email if you want more info on it.

I think that you can get 42-47 HP with pully,and chip alone. With other tweeks exhaust and air filter maybe 50 HP. I dont see much over this unless you change the the inlet and pressure pipeing and install a larger intercooler.

do you have a chart showing the torque increase too. What would be really helpful. Is one gear, showing rpm (x axis) vs power (hp, torque on the y axis, but scaled)

are we convinced yet? it seems like there is always another piece of technical info that is needed? i don't really know about dynos, etc, but i can see that there is about 30hp increase. is my interpretation correct or will the additional torque charts provide contrary evidence? or maybe not such a great improvement?

how do i tell that the red (greater line) is the after-chip run?

and it looks like 5-10 hp increase over most of the speeds 0-55 mph and 30hp only at 120mph. so, i'd interpret that as, in reality, a 5-10 hp increase for real-life driving. still compelling especially w/ the fuel efficiency increase.

what are the peaks? gear shift changes? why the big dip at 52 mph and 87 mph?

I posted a similar question on the Performance Mods forum: but with a supercharged engine would one really see that big of a difference with an air-filter/cold air intake? I can see how it would help a normally aspirated car, especially since there is usually a different inlet pipe leading into the throttle body. But with a supercharged car the amount of air in the intake manifold is governed via the supercharger itself and is cooled by the intercooler (as supercharging will heat up the compressed air), and considering the rumor has it that the Upsolute chip modifies the activity of some computer acutated bleed valve then the engine is already getting a good amount of air that can be increased with no filter change. However, I can see how increasing intercooler efficiency should be the way to go as this would provide cooler denser air with which to make more power.

Cheers, BT

Trench,
I agree with you the gains by modifying the air filter or air box will not be as dramatic on a forced induction engine verses a naturally aspirated engine. Increasing the efficiency of the intercooler will return the largest gain for modifications to the induction system.

from what randy has posted earlier he stated that with K&N air filters there may be a small hp increase but mostly its most just a faster spool up time with turbo and superchargered cars. So basically if i am going to get a chip or a pully i will definatly get a air filter too. cause with K&N or ITG, you can use it over and over and over. Plus its not really that much $ either.
